The event is scheduled to begin at approximately 18:49 UTC. It is recommended that you start listening approximately 10 minutes before this time. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between OR4ISS and ON4ISS. The contact should be audible over Belgium and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. There are two schools participating in this event; South Street Elementary School and Westside Middle School Academy (WMSA). Westside Middle School Academy offers students a unique opportunity to partake in rigorous hands-on activities. There are two academies at Westside, STEM and Global Studies. In the STEM academy, students take part in engineering projects such as building small paper boats, designing escape pods and launching weather balloons. Students also participate in the Connecticut Invention Convention and Connecticut State Science Fair. Teamwork is essential at Westside. Our teachers encourage us to go beyond our limits and to give our best effort. In addition, Westside has a culture of safety, respect and responsibility (S R 2), which ensures that all students are learning in a safe environment. Finally, the diversity of our school community enhances the learning experience for all students. South Street School is one of 13 elementary schools in the city of Danbury. The staff of South Street prides themselves on the diversity of the school as it compares to the rest of the district as well as the state. The state average for Hispanic students making up the school population is 22.1%, South Street boasts a solid 64.5% Hispanic population. The "Melting Pot" community that is found at the school allows for an incredible mix of background experiences, cultural traditions and a wealth of different styles of learning. The majority of students gets to and from school by walking with their families or friends and the sense of community and family is strongly felt in the school and the surrounding areas. Students at South Street thrive in an environment that emphasizes inquiry based Participants will ask as many of the following questions as time allows: >From South Street 1. What is the most difficult part of your job? 2. What type of microorganisms are dangerous in space? What micro-organisms are important and needed in space? 3 What type of medical testing does and astronaut have to go through to be physically and mentally fit for duty? 4.

The event is scheduled to begin at approximately 08:38 UTC. It is recommended that you start listening approximately 10 minutes before this time. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be a telebridge between NA1SS and LU1CGB. The contact should be audible over Argentina and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in French. The Principality of Monaco is a territory of only 2.02 km2. It is the second smallest independent state in the world (after the Vatican). At the time of the last census in 2015, the Principalty had 38,400 inhabitants. Monaco is located at the edge of the Mediterranean sea, along the French Riviera, about twenty kilometers from Nice. The principality is governed since 2005 by the sovereign Prince Albert II of Monaco. This small country attracts many tourists (formula One Grand Prix, the casino, the oceanographic museum, the prince's palace ...) Our school "le cours Saint maur" is a private Catholic school under contract and is located in Monaco. It hosts about 220 pupils from Kindergarten (3 years) to 5th Grade (10-11 years). This year, we will celebrate 80 years of school. For several years, my class participated in intergenerational meetings with the Speranza Albert II center. This center is a day care center specialized in the care of people affected by Alzheimer's disease Or with cognitive impairment. Intergenerational exchanges are an opportunity for sharing both cognitively and emotionally. They allow an interaction where the two parts learn from each other and allow mutual enrichment. Since September, we have been working together on the "Thomas Pesquet" project. We meet twice a month at the Speranza Center and we work in workshops in pairs with elderly people, these are always moments full of emotion.

My setup is minimal, and am just using a Arrow antenna mounted to a camera tripod. I do have a GaASFET preamp, but the LNA in the SDRPlay seem to do the trick without the preamp. I use SDR Console software, which is powerful and a lot of options in it. It is above and beyond HDSDR and SDR#!!! The other nice thing with using a SDRPlay on Sats, is you can see the entire band for downlinks, and at a touch you can move to another signal in the linear sats. I record the passes audio and listen to them back after also. Hope this helps a little, and 73!

Message-ID: <050908d4f3db82f7a459af4df81b24ac@mail.gmail.com> Fired up our next PSK31 cubesat card for first test and the ground station got full S9 carrier but signal was full of noise totally masking the PSK31 tones. Turned off. Channel was clear. Then opened squelch and there was S9 noise over 5 Mhz around our UHF downlink. Went down the halls with HT and signal tapered slowly down in all directions. Came back and with 1? of wire in the HT antenna connector narrowed it down to a cheap battery charger. Lesson over and over again, is that a squelch HIDES everything Even 20+S9 noise sources. Zero bars while squelched. Reminded me of when we had local repeater problems. Turns out it was the megawatt balloon radar operating in VHF looking over Washington DC. No one could hear it with their radio squelched. But open the squelch and every channel throughout 2m would show 60+S9 bars on the noisy trash. It was similarly baffling at the peak of packet in the 90?s when some hams would complain that their packet system wasn?t working, and yet they never turned up the volume to listen by ear to the channel to see what was going on. I still see that sometimes in our students who think that all you have to do is hook-up two wireless thingy?s and is should just work? but never think to listen to a channel or use a spectrum analyzer to see what they are dealing with. Turns out, this battery charger (now that I remember) was the SAME one that got me several years ago. I was just too old to remember until I had again done the full DF search through the entire academic building and ended up right back at the same point.

It works but you get the performance that you pay for. If you're willing to part with another $20, you want to consider the Low Noise Amplifier for the RTL-SDR from janieelectronics. I ordered one through eBay and received it yesterday. It ships from Hungary so a little patience is needed with respect to delivery time, but I did get mine a day before the last predicted delivery date. I used it last night and it works! I definitely downloaded more data packets from AO-85 than I have been getting lately. I also tried it on a pass of AO-73 that was at a lower angle than I would normally attempt. I was able to download data from that pass, which I probably would not have gotten without the preamp. I wasn't paid and didn't get a discount for the review. I am just happy that an inexpensive item actually works as promised. If you are as cheap as I am and looking for a preamp for your SDR, consider the janieelectronics Wide-Band LNA. It works for me.

This live Earth-to-space radio contact will last for 10 minutes starting at 2:30 pm CST Feb. 9 in Space Center Houston's Mission Briefing Center. The special event is a feature of the nonprofit Space Center Houston's 23rd Space Exploration Educators Conference. The amateur radio interview is part of the Amateur Radio on the International Space Station program (ARISS) where excited students can link with astronauts living and working on the ISS. Since the ISS first opened for habitation in 2000, ARISS volunteers have hosted an astounding 1,076 ARISS radio education contacts. This contact should be audible over the US Eastern Seaboard; listeners can tune to 145.80 MHZ. Here is a sampling of students' questions: ? Since hair root cells actively divide in a hair follicle, does zero gravity affect this process? ? Do you have a time zone in space? ? What do you feel is the most important accomplishment performed by the space station that will help science? The three-day conference draws more than 500 hundred educators from around the world to experience hands-on learning in sessions led by rocket scientists, astronauts and renowned educators. Space Center Houston is the cornerstone of the mission of The Manned Space Flight Education Foundation, a 501?3 nonprofit science and space learning center with extensive educational programs. The mission is to inspire all generations through the wonders of space exploration. Space Center Houston is the official visitor center of NASA Johnson Space Center. The mission of Seabrook Intermediate School is to ensure each student explores and discovers unique talents, passions, and abilities through a dynamic system, including the Science Magnet Program. About ARISS: Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crewmembers aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

What a fantastic idea and opportunity to engage your daughter in the ARISS program. You turned a passive event (just listening in) into an active learning experience. I bet that with a little preparation, the same technique could be leveraged / expanded to a classroom situation. Besides direct RF, the contacts that are live-streamed could be used as well, all time-zone permitting of course. We generally only get a few days to a week advance notice of the questions. Are they available sooner through other channels? That would be the biggest challenge to leveraging this to a more expanded audience.

This may be the last activation of K2BSA stroke five from the museum as the Irving TX location here will be closing AND relocating to the Philmont Scout Ranch in northern New Mexico after June of this year. It's been a fun run of doing radio merit badge classes from the museum but you will hear the callsign more in the future as we move to other venues in the area to introduce scouts to amateur radio and also amateur satellite.

I am at the AMSAT booth inside a hangar at the Palm Springs Hamfest, getting ready for this event to officially start at 9am/1700 UTC. So far, I am planning a couple of demonstrations for the start of the event, from outside the hamfest site (Palm Springs Air Museum)... AO-73 at 1656 UTC (8.56am PST - around the time the hamfest starts) FO-29 at 1731 UTC (10.31am PST) These demonstrations will be done in front of the museum, near the US Navy A-6 Intruder on display. The FO-29 demonstration wil be done using one FT-817ND and my Elk log periodic antenna, and I plan on using 145.930 MHz (+/-) as my uplink for the 1731 UTC pass. There will be other demonstrations during the day. Where possible, I will try to post those mentions here on the -BB, but looking at my @WD9EWK Twitter feed is probably a better way to go.

Upcoming Contacts * A telebridge contact via K6DUE at the Space Exploration Educators Conference, Houston, Texas, is scheduled for Thu 2017-02-09 20:30:10 UTC 21 deg. The scheduled astronaut is Thomas Pesquet, KG5FYG. The Manned Space Flight Education Foundation Inc. is a 501(c)(3) nonprofit educational foundation offering extensive science education program and a space museum. It is the Official Visitor Center of NASA Johnson Space Center and the only Smithsonian Affiliate in the greater Houston area. Educational emphasis is placed on science, technology, engineering and mathematics (STEM) in a fun and engaging way. It uses space exploration to inspire wonder and interest in science and math. Space Center Houston offers a rich array of education programming for teachers and students, providing extraordinary learning opportunities. Inspiring young people to choose careers in STEM is one of the outcomes of our program. Education programs are based on data-supported evidence of effective learning and teaching methods. This specific contact will be taking place during the Space Exploration Educator Conference, which engages teachers from around the world for three days of hands-on learning and exceptional keynote speakers. Students from the Science Magnet Program at the Seabrook Intermediate School in Seabrook, Texas will be participating in the Amateur Radio on the International Space Station (ARISS) contact. Seabrook Intermediate School is the leader in innovative education. Their mission is to ensure that each individual explores and discovers unique talents, passions, and abilities through a dynamic system distinguished by limitless opportunities (including the Science Magnet Program) that foster collaboration, creativity, intrinsic motivation, respect for diversity, and citizenship to develop a productive role in society. The Science Magnet Program at Seabrook Intermediate School is offered to students in grades 6-8. The school provides a unique science curriculum for all students while providing additional science electives and opportunities for students enrolled in the Science Magnet Program. * A direct contact via K4PSA with students at the Palmetto Scholars Academy, North Charleston, SC, is scheduled for Fri 2017-02-10 17:59:18 UTC 38 deg. The scheduled astronaut is Shane Kimbrough, KE5HOD. Palmetto Scholars Academy is a public charter school, providing a gifted curriculum to students in grades 6-12 in North Charleston, South Carolina. 6 years ago PSA opened in a converted day care center and was the lowest funded school in America. It was started by a group of concerned parents who wanted to meet the needs of gifted students. In those early days, board members took out second mortgages to meet teacher payroll, and parents pulled together daily to send in supplies. Despite challenges, PSA rose above the decrepitude and started its tradition of achievement, earning their mascot name of Phoenix. PSA is a student haven for gifted students. ???It???s okay to be a nerd here??? and ???It???s cool to be smart??? illuminate the student culture at PSA. To meet the intellectual needs of gifted students, PSA participates in many challenges such as VEX Robotics, VEX IQ Robotics, FIRST Robotics Competition, Ham Radio, Lowcountry Science Fair, Odyssey of the Mind, and the Student Spaceflight Experiments Program (SSEP). PSA students have designed three experiments through the SSEP. Two experiments reached the ISS and returned to Earth, although the second experiment blew up on the Orb-3 and Falcon 9. The third experiment launches next month. Students also send experiments via PongSats, Cubes in Space, and student-launched high- altitude balloons. PSA has a Ham Radio Club and their own vanity call sign, K4PSA. The club meets every other Friday for 1 ?? hours and after schools on Friday. Since its inception in 2015, the club has gotten 6 students licensed for ham radio. These students will be the student liaisons and leaders for this ham radio contact. PSA has established itself as a distinguished charter school in South Carolina. With a new building, better funding, and culture of achievement, PSA rises from the ashes like the Phoenix and challenges its students to reach the stars.

The fun part of it is that I'll be FM SAT equipped. I've attained all requirements to operate as CU2ZG/VK2 and ZL/CU2ZG, under CEPT. Urban environment permitting I'll be active while on QF56, RE44, RF72, RF73, CN89, FN03, JO22, and probably other in inner Australia, operating SO-50 and BY70-1 (while in orbit), plus AO-85 and LilacSAT-2 (if on). Given allowed weight and space restrictions while on travel, I'll be equipped with a Wouxun KG-UV9DPlus and a Nagoya RH-770 telescopic whip, the same setup I've use in several other quick rover ops. If any of you happen to be nearby please drop me a private email. Special interest on meeting local hams and AMSAT branches. I'd like to state my thanks to the Singapore SARTS staff that, despite I had not attained a temporary license to operate from their country, have been of grateful help. 73 de CU2ZG Pedro --- Este e-mail foi verificado em termos de v?rus pelo software antiv?rus Avast. https://www.avast.com/antivirus -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!) FUNcube-2 aka FUNcube on UKube The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/ All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

I either read or heard about it many years ago, got a clear mental image of the concept from the description at the time, and that's all I remember. It seemed like a really neat idea to me, and (if I recall correctly) it was an AMSAT innovation. Come to think of it, maybe it wasn't intended for a P3 bird, but maybe for a planned geosynchronous satellite, instead. As such, it may have never been put into practice. 73 de John, KD2BD From gabrielzeifman at gmail.com Tue Feb 7 18:17:37 2017 From: gabrielzeifman at gmail.com (Gabriel Zeifman) Date: Tue, 7 Feb 2017 12:17:37 -0600 Subject: [amsat-bb] Back from VE8 Message-ID: Hello fellow bird trackers and sky talkers, I have safely returned to EM15 from the reaches of the sub-Arctic. What a great trip with 1,140 contacts in the log (over 900 already with confirmations in LoTW). The trip started out very well filling in many holes in holes in many people's 488 maps in DN land and a bit of EN land. After crossing the border, many never before heard grids were activated. The real fun began after crossing the 60th Parallel into the Northwest Territories and into DP land, a field that most people had never worked. The conditions were great, temperatures weren't absurd (don't get me wrong, still damn cold). The Winter Roads I did get on were great (lots of fun working from the Detah Winter Road on Great Slave Lake in DP22). Nothing greater than working across the Atlantic while on an ice road under the northern lights... DP00 was definitely the most absurd grid I visited, on the Trout Lake Winter Road. Next time I'll have to go further and get into CP90. Everything seemed to go very well up until around day three in VE8 when all of my coax jumpers began acting up. I still managed to get on some passes with this setup and make some great contacts. It eventually got bad enough where I had one jumper that seemed to work alright and the whip on my car and used that for 2m, basically limiting me to FO-29 (where I was very quiet most of the time). Upon getting into BC, John K8YSE found Tim VE7XIX (former VE5SAT, AC2GK). I met up with Tim in Fort Saint John, BC and he had everything we needed to make a temporary repair on two of my jumpers. Thanks to Tim the portion between BC and Portland, OR was saved (solder and lots of gorilla tape). Upon reaching Oregon and California, thanks to Clayton W5PFG and Steve N9IP I was able to get some new coax jumpers. The drive down the coast and through the desert was great, many rare grids activated. A memorable time was driving through LA and listening to the 147.435 repeater and checking into the "Bong Hit Net" at 4:20PM. It was great to meet many hams throughout the trip, in both the US and Canada. Especially fun was attending the Palm Springs Hamfest and meeting many SoCal sat ops (and a certain displaced 9 lander). My buddy Ethan also passed his tech at at the hamfest and will soon be KE0xxx and hopes to get on the birds soon. Was great to meet John K8YSE in Mesa and get EN91 as a /r grid (easiest /r grid I've ever gotten). All contacts are uploaded to LoTW. If you are missing anything, now would be a good time to start emailing. Big thanks to Dave KG5CCI, Fernando NP4JV, and Paul N8HM for being my QSL managers. Those three received my logs via Iridium messages and uploaded. If you enjoyed receiving instant QSLs from the sub-Arctic out of range of any terrestrial networks, thank those three, it wouldn't have been possible without them. Thanks to all for all the contacts, it was a ton of fun and I look forward to the next one (I'm itching to use V31NJ, hint hint)! 73, Gabe NJ7H From david.xe3dx at gmail.com Tue Feb 7 18:36:41 2017 From: david.xe3dx at gmail.com (David Maciel (XE3DX)) Date: Tue, 7 Feb 2017 12:36:41 -0600 Subject: [amsat-bb] Back from VE8 In-Reply-To: References: Message-ID: Always do a good job, Congratulations Gabe, for my geographic location and antennae work very little in great travel miles and grids I am happy, you help many people to get new grids.

Sounds as you got it under control. I used a 16 element CC cross-yagi for AO-10 and the phasing harness was not according the dimensions one would calculate but it worked. I traded it for a M2 436CP42UG for AO-40 (which I still have) and the CC 20 element 2m satellite antenna. 2m went kaput early so I used the 432 yagi a lot for uplink in mode-US or LS. I had a 50w linear which was overkill (usually ran about 20w). The dish photo I shared was my mode-S downlink using preamp to two Drake converters. M2 is marketing an 8 element cross yagi CP antenna for 2m which is probably just right in gain. Its pretty spendy, though. If you have a couple 3 or 4 element yagi's you can combine them for CP and even switchable in sense using a relay or two. I am using a 2M7 by M2 linear yagi and only have 26 elements of the big M2 436 antenna mounted. Not QRV yet as I am planning major changes next summer. GL on whatever you decide. 73, Ed At 03:45 PM 2/7/2017, Dave Mann wrote: >I just finished assembly of the Cushcraft cross-polarized yagi which >I bought from a fellow Ham. It was like new.

Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. Palmetto Scholars Academy is a public charter school, providing a gifted curriculum to students in grades 6-12 in North Charleston, South Carolina. 6 years ago PSA opened in a converted day care center and was the lowest funded school in America. It was started by a group of concerned parents who wanted to meet the needs of gifted students. In those early days, board members took out second mortgages to meet teacher payroll, and parents pulled together daily to send in supplies. Despite challenges, PSA rose above the decrepitude and started its tradition of achievement, earning their mascot name of Phoenix. PSA is a student haven for gifted students. "It's okay to be a nerd here" and "It's cool to be smart" illuminate the student culture at PSA. To meet the intellectual needs of gifted students, PSA participates in many challenges such as VEX Robotics, VEX IQ Robotics, FIRST Robotics Competition, Ham Radio, Low country Science Fair, Odyssey of the Mind, and the Student Spaceflight Experiments Program (SSEP). PSA students have designed three experiments through the SSEP. Two experiments reached the ISS and returned to Earth, although the second experiment blew up on the Orb-3 and Falcon 9. The third experiment launches next month. Students also send experiments via PongSats, Cubes in Space, and student-launched high- altitude balloons. PSA has a Ham Radio Club and their own vanity call sign, K4PSA. The club meets every other Friday for 1 ? hours and after schools on Friday. Since its inception in 2015, the club has gotten 6 students licensed for ham radio. These students will be the student liaisons and leaders for this ham radio contact. PSA has established itself as a distinguished charter school in South Carolina. With a new building, better funding, and culture of achievement, PSA rises from the ashes like the Phoenix and challenges its students to reach the stars. Participants will ask as many of the following questions as time allows: 1. What is the first thing that you do after you receive the SSEP experiments? 2. Besides Earth, what interesting objects have you seen from the view on the ISS? 3. Are there plans to send a 3D printer to the ISS in order to print food? 4. Do you have to wear a uniform, or can you wear anything you want in your free time? 5. Do you play pranks on each on the ISS? 6. How are you affected by relativity at the current speed you are going, and do you have some sort of atomic clock on board to measure the effect? 7. Is there one person that is trained to fix the spacecraft, or is everyone able to fix it? 8. We sent watermelon seeds in microgravity on a sounding rocket out of Wallops Island. Do you think watermelons would be a good fruit to cultivate on the ISS? 9. Does microgravity affect your ability to talk? 10. Are there laws in space that don't apply on Earth? 11. Do you think re-usability will become a standard for all rockets launched by the United States soon in the future? 12. In your opinion, what is the greatest recent innovation in spaceflight? 13. What games, if any, do you play on the ISS that can only be played in microgravity? 14. How do you feel about civilian space travel, if it ever happens? 15. Can astronauts observe religious services aboard the ISS? 16. Are there any modifications to your 3d printer to allow it to print in space? 17. What do you plan to do once you are finished being an astronaut? 18. If you could choose any animal to accompany you to space, without it affecting them, or harming anyone, what animal would you choose? 19. What is the most interesting item that you have printed with your 3D printer? 20. Have your opinions changed after seeing the world from a perspective no one else has seen? 21.

I am a broadcast TV engineer and we had a group from the local high school come to our studios where we linked them up with the ISS crew. Not on the expected 2 meter145 frequencies, but up on 14Ghz and down on 12Ghz, Ku band. The link actually went via NASA's Houston comm center and not directly to the ISS. Our uplink dish is 12 meters in diameter and capable of an ERP of about 3.5 million watts. It's been a while since I did an uplink as almost everything coming in and going out of our station is Fiber based these days. Even our Live trucks are moving away from microwaving their video back to the studio in leu of a neat little box called the "Back Pack". It's basically a box with 6 cellular connections all bonded together to allow very high bandwidth. The Photog straps it on his back and plugs his camera directly into it. No more need of an expensive microwave truck. There are also some other pretty cool technologies coming down the pike that I can't event talk about. The future of communications will be changing whether it be watching TV or talking on your iCom Amateur radio to the LEO satellites. Can't wait to see what the future holds.

The flight, C-37, will be carry a total of 104 satellites into orbit. Nayif-1 has been developed by the Mohammed bin Rashid Space Centre (MBRSC) and American University of Sharjah (AUS). The UAE's first Nanosatellite was developed by Emirati engineering students from AUS under the supervision of a team of engineers and specialists from MBRSC within the framework of a partnership between the two entities, aiming to provide hands-on experience to engineering students on satellite manufacturing. The spacecraft includes a U/V linear transponder and telemetry transmitter. It employs enhanced oscillator circuitry and includes an active attitude determination and control system. As with previous missions carrying FUNcube payloads, AMSAT-UK would very much like to receive as many reports from stations around the world, especially during the first few minutes and hours after launch. We expect that the first signals may be heard in North America during the mid evening hours (local time) on Feb14th There is a mission specific Telemetry Dashboard for this project and this can be downloaded from http://download.funcube.org.uk/Nayif-1_Dashboard_1038_installer.msi and, in a similar way to the FUNcube-1 Dashboard, this will be capable of uploading the telemetry received to a central Data Warehouse. Guidance Notes for the installation of the Dashboard, integration with a FUNcube Dongle and the Data Warehouse have been prepared for the Nayif-1 mission. These can be downloaded from Nayif-1 Dashboard Notes ver 1.0b.pdf A file to test that the Dashboard and Warehouse configuration are working correctly can be downloaded from http://download.funcube.org.uk/nayif1_testfile.funcubebin The operating frequencies for the spacecraft will be: Telemetry 145.940MHz using 1k2 BPSK to the FUNcube standard. Transponder Uplink on 435.045 ? 435.015MHz Downlink on 145.960-145.990MHz Initial operations of the spacecraft will be in a low power "safe" mode where only the telemetry transmitter is activated. More details about the launch, exact deployment time and pre-launch TLE's will be made available as soon as they become available; in the meantime we will really appreciate your support! 73 Graham G3VZV From m5aka at yahoo.co.uk Wed Feb 8 15:36:27 2017 From: m5aka at yahoo.co.uk (M5AKA) Date: Wed, 8 Feb 2017 15:36:27 +0000 (UTC) Subject: [amsat-bb] Nayif-1 + ISS SSTV + Uni CubeSat Opportunity References: <1413693683.930073.1486568187955.ref@mail.yahoo.com> Message-ID: <1413693683.930073.1486568187955@mail.yahoo.com> Nayif-1 CubeSat Launch Announced https://amsat-uk.org/2017/02/08/nayif-1-launch-announced/ ISILaunch Services Blog http://blog.isilaunch.com/category/isilaunch17/ MBRSC and AUS Announce launch of Nayif-1 http://m.dubaiprnetwork.com/pr.asp?pr=118386 Receive Pictures from Space ?

The downlink frequency is expected to be 145.800 MHz and the transmission mode is expected to be PD180. This opportunity should cover most of the world during the operational period. The MAI-75 experiment uses a notebook computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the ham radio, specifically the onboard Kenwood TM D710E transceiver. Images received can be posted and viewed at https://ariss-sstv.blogspot.com/ Please note that the event, and any ARISS event, is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time.

He has asked me to help funnel QSL requests to him while he is at sea so that he can process them and mail them from ports as he travels. Yuri does not process qsl requests when he is not on a ship. The following procedure only applies to contacts made during this season from the M/V Chestnut. Previous seasons will be handled by his manager Eugene, UX0FY. Eugene has all the logs for previous seasons and can be contacted through his qrz.com email address. Please contact Eugene before sending anything in the mail to him and ask for instructions on how to proceed. You may prepare a logsheet of QSO's that Yuri can print, verify, sign and mail from one of his destination ports. An example of a suitable logsheet can be found at papays.com/sat under the UT1FG/MM QSL Instructions link at the top of the page. Please use the following conventions when preparing the logsheet: 1. List only one contact per grid. 2. Only request confirmations of NEW Grids. 3. Use Excel or a similar program to create the logsheet. 4. Save the Logsheet to a .pdf If your program cannot save to a .pdf, download a free program like Bullzip that will install a .pdf printer that you can print to and create a .pdf file. 5. Each page should stand alone; there should be a place for Yuri's signature on each page. 6. Incude your COMPLETE Mailing Address on each page. 7. Name the logsheet file with this format: Yourcall_UT1FG_DateLastQSO for example: DJ8MS_UT1FG_10Feb2017.pdf 8. Email your file as an attachment to: k8yse at papays.com with the subject line the same as the .pdf file name: DJ8MS_UT1FG_10Feb2017 10. Please be sure to follow the example on the website papays.com/sat/ut1fgqsl.html Consistency will help Yuri process requests more efficiently. 11. If there are qso's on your list that are not in the log, Yuri will draw a line through them and initial. I will send an acknowledgement email when I receive a request. This way you will know that Yuri will have your logsheet. If Yuri tells me that he has mailed your logsheet, I will post that information on the bulletin boards. Yuri's time when nearing or in port is very limited. He has a lot of responsibilities to carry out and large amounts of paper to process along with requests from his Company. He has more time when he is sailing. Let that guide you when deciding when you email your requests. A good time to mail your request is when Yuri is about 5 days from making port. Follow him at marinetraffic.com (M/V Chestnut - bulk Cargo). This new procedure may be changed or stopped depending on how it goes. Hopefully this will work well and Yuri will find it acceptable. We are very fortunate that Yuri operates from so many water grids that otherwise would never be on the satellites. His passion for satellites is amazing. Have fun working him. 73, John K8YSE --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From va6bmj at gmail.com Thu Feb 9 17:55:05 2017 From: va6bmj at gmail.com (B J) Date: Thu, 9 Feb 2017 17:55:05 +0000 Subject: [amsat-bb] Ideal Mass For Small Satellites Message-ID: http://spacenews.com/smallsat-builders-admit-a-little-bigger-might-be-better/ 73s Bernhard VA6BMJ @ DO33FL From n4ufo at yahoo.com Thu Feb 9 21:29:50 2017 From: n4ufo at yahoo.com (Kevin M) Date: Thu, 9 Feb 2017 21:29:50 +0000 (UTC) Subject: [amsat-bb] SO-50 09 FEB 2017 1720z recording?

In-Reply-To: References: Message-ID: YES! very fun project. I caught the same pass Paul is referring to, we only got 7 frames :-( here at VT. The fun (and proud) part for me was it was all part of a undergraduate class project for the satellite communications course where the students had to simulate the orbits (using STK), predict pass windows where the crosslink was possible (line of sight from AO73 to FO-29 and LOS from FO-29 to VTGS), then for each pass window do a link budget computation for each 1 second timestep of the established chain event, and do a doppler curve estimation. The proud part was that two of my students (undergrads) were dead on with their predictions, and were present during the decoding event and therefore got a half letter grade bump on their project grade since we successfully demodulated packets based on their simulations and predictions (not only did they pick a good window with a higher chance of success, their doppler curve matched nearly perfectly, allowing us to tune correctly to decode the packets). The magic part that folks should keep an eye out for is trying to make the attempt when AO-73 is in sunlight since you get a 10 dB bump in output power from AO-73 in the beacon. That was also a great teaching moment during the attempt where we could see the signal drifting (up in frequency since AO73 and FO29 were closing on each other, not down like you might expect with normal doppler) in the spectrum display, but barely breaking the noise floor, then all of a sudden there is this 10 dB jump in SNR (AO-73 coming out of shadow and into sunlight) and packets start decoding! very fun project, very hands on for the students. Do some research, develop a simulation, synthesize something meaningful about the real world from the simulation, try it in the real world, and then explain what worked and what didn't and why, but with actual satellites in orbit! Also, they used the free version of STK in the class project and then wrote scripts in python to process CSV data generated by STK, so all of this is simulation stuff is doable by hams with completely free software and tools.

So if one line was 1/2 wavelength long, the other line would be 1/4 wavelength or 3/4 wavelength long, if the horizontal and vertical elements were at exactly the same spot on the boom. The more common method is to set the vertical and horizontal elements at 1/4 wavelength different locations on the boom, and then you only need two feedlines that are exactly the same length. The advantages there include the fact that phasing lines' lengths need to take account of the velocity factor of the coax, whereas placing elements at different boom locations is equivalent to a velocity factor of 1.0 (air). So how to get the two feedlines exactly equal? Besides lining them up side-by-side when cutting them, you can connect one end of the cables to a 2-port power divider (or a simple T connector if you aren't worried about an impedance bump to your signal source), and the other ends of the cables to the X and Y inputs of an oscilloscope that has X-Y plotting capability. For two equal lengths, you should get a perfect diagonal line, and if one cable is a bit longer than the other, you will get a long, slender, diagonal ellipse. If the cables differ by a full 1/4 wavelength (or 3/4 wavelength), you would get a perfect circle. If the cables differ in length by exactly 1/2 wavelength, you would get a perfect diagonal line with the opposite tilt direction as the zero-difference tracing.

Message-ID: Hi All, The launch time for the Nayif-1 CubeSat has been confirmed as 03:58UTC on February 15th 2017 on the PSLV C37 vehicle and a set of pre-launch TLEs have now been released: NAYIF 1 17002U 17002A 17046.17824931 0.00000000 00000-0 00000-0 0 9993 2 17002 97.5521 107.5843 0004848 278.6481 296.8511 15.21991390 01 This file can also been downloaded from here http://download.funcube.org.uk/nayif_tle.txt We expect that the FUNcube transmitter on Nayif-1 will activate at approximately 05:06UTC, but the exact timing is still to be confirmed! Initial transmissions will be in ?safe? mode and will be of the 1k2 BPSK telemetry only with approx 50mW of RF power. If the predictions are correct, the spacecraft will be heading north over Mexico and the western parts of the US and Canada. During the Launch and Early Operation phase (LEOP) of the mission, the Nayif-1 command team will be headquartered at the American University of Sharjah Ground station in the United Arab Emirates. They will obviously be especially keen to have all possible reports of signal reception during this first orbit! To encourage everyone to take part, there will be a small prize for the station that submits the first data to the Nayif-1 Data Warehouse and perhaps an extra reward if they manage to receive the very first frame transmitted by the spacecraft! This should have the sequence number 5471 or 5472. Details of the Nayif-1 frequencies, together with details of how to the download the Dashboard can be found here https://funcube.org.uk/2017/02/08/nayif-1-launch-date-now-confirmed/ The Data Warehouse is still under final development but a preview can be seen here: http://data.amsat-uk.org/nayif1/index Please note that if you are already a registered user of the FUNcube Dashboard then you do not need to re-register. Your existing details will transfer automatically to the new Dashboard when you run it for the first time. If you run the test file with the Nayif-1 Dashboard please do not expect the Warehouse to show the data - it is from an earlier date than that is already displayed. However the ?packets uploaded? tab at the bottom right corner of your Dashboard will show that the files have uploaded OK, that all is well with your system and that it is ready for action. We are hoping that the actual launch will be webstreamed and details of this will be made available as soon as possible. The AMSAT-UK and -NL team will also be using the #funcube IRC channel on launch day and you will be very welcome to join them there. If you do not have the Dashboard available then please submit your heard reports here. A web client can be found at http://irc.lc/freenode/funcube if you do not have an IRC client installed. 73 and thanks for your support Graham G3VZV From g0kla at arrl.net Sat Feb 11 15:23:32 2017 From: g0kla at arrl.net (Chris Thompson) Date: Sat, 11 Feb 2017 10:23:32 -0500 Subject: [amsat-bb] AMSAT NA telemetry server down Message-ID: The AMSAT NA telemetry server has been taken down while we troubleshoot an issue.

And if the "mechanical method" of getting the quarter wave offset between elements is used, then no need to get coax feeders of different lengths by exactly a quarter-wave after adjusting for velocity factor. Just two pieces of 50 ohm coax of exactly the same length, which can be easily verified with relatively simple test equipment, namely a dual-channel oscilloscope with x-y plotting mode.

February 12, 2017 To All RADIO AMATEURS BID: $ANS-043.01 SSTV From The ISS February 13-14 An MAI-75 Experiment SSTV event is planned to begin on Monday, Feb. 13 from 09:25-18:00 UTC and Tuesday, Feb. 14 from 11:25-16:30 UTC. The downlink frequency is expected to be 145.800 MHz and the transmission mode is expected to be PD180. This opportunity should cover most of the world during the operational period. The MAI-75 experiment uses a notebook computer on the ISS Russian Segment, which stores images that are then transmitted to Earth using the ham radio, specifically the onboard Kenwood TM D710E transceiver. Images received can be posted and viewed at https://ariss- sstv.blogspot.com/ Please note that the event, and any ARISS event, is dependent on other activities, schedules and crew responsibilities on the ISS and are subject to change at any time. While preparations are being finalized please check for new and the most current information on the AMSAT.org and ARISS.org websites, the AMSAT-BB at amsat.org, the ARISS facebook at Amateur Radio On The International Space Station (ARISS) and ARISS twitter @ARISS_status for the latest information on this event. [ANS thanks ARISS for the above information] --------------------------------------------------------------------- K5T Grid Expedition to DL88jx Several satellite operators will make their way down to the southernmost tip of Texas' "Big Bend" on Sunday, February 12, 2017. Operating from within Big Bend National Park's Talley Campground via amateur satellites, grid chasers will have a shot at the ellusive DL88jx for a period of roughly 18 hours. Listen for K5T on FM and SSB satellites starting roughly at 21:00 UTC on February 12 through 15:00 UTC on February 13. ISS packet is possible but not planned. You may occasionally catch K5T in grid square DL89. Pass/schedule requests will not be honored on this trip. Some HF operation may occur.

Dave and his daughter downloaded the list of questions for the ARISS QSO between Astronaut Shane Kimbrough and South Street School, Danbury, Connecticut USA. He and Erin researched the questions and made a list of projected answers for them. The contact was made with ON4ISS, an ARISS telebridge station in Belgium, and Erin and Dave were able to listen to the transmission live from from their QTH in South Yorkshire, UK. Dave videotaped the QSO and posted it online at: https://www.youtube.com/watch?v=MzQbyIH8Qwg This is an excellent example of how to integrate Amateur Radio and the the ISS without being directly part of an ARISS contact. The examples can be used with any demo or within a planned classroom setting. This is a great example of how to introduce a STEM related activity and create an interest in the hobby at the same time.

[ANS thanks Debra K1DMJ and the ARRL for the above information] --------------------------------------------------------------------- University CubeSat Opportunity The UK Space Agency is encouraging university students to take advantage of a new opportunity to build and test their own CubeSats The aim of the The Fly Your Satellite! program is to support university student teams with educational CubeSats throughout the assembly, integration, testing, and verification process. By participating in the programme, students will implement standard practices for spacecraft development; receive support from experienced ESA specialists; attend tailored training courses; and will be offered access to state-of-the-art test facilities. ESA say only launch opportunities from the International Space Station (ISS) are envisioned, and CubeSat teams applying need to ensure that their mission complies with a deployment to orbit from the ISS.

The flight, C-37, will be carry a total of 104 satellites into orbit. Nayif-1 has been developed by the Mohammed bin Rashid Space Centre (MBRSC) and American University of Sharjah (AUS). The UAE?s first Nanosatellite was developed by Emirati engineering students from AUS under the supervision of a team of engineers and specialists from MBRSC within the framework of a partnership between the two entities, aiming to provide hands-on experience to engineering students on satellite manufacturing. The spacecraft includes a U/V linear transponder and telemetry transmitter. It employs enhanced oscillator circuitry and includes an active attitude determination and control system. As with previous missions carrying FUNcube payloads, AMSAT-UK would very much like to receive as many reports from stations around the world, especially during the first few minutes and hours after launch. We expect that the first signals may be heard in North America during the mid evening hours (local time) on Feb 14. There is a mission specific Telemetry Dashboard for this project and this can be downloaded from: http://download.funcube.org.uk/Nayif-1_Dashboard_1038_installer.msi and, in a similar way to the FUNcube-1 Dashboard, this will be capable of uploading the telemetry received to a central Data Warehouse. Guidance Notes for the installation of the Dashboard, integration with a FUNcube Dongle and the Data Warehouse have been prepared for the Nayif-1 mission. These can be downloaded from: http://tinyurl.com/ANS043-Nayif-1-Dashboard A file to test that the Dashboard and Warehouse configuration are working correctly can be downloaded from: http://download.funcube.org.uk/nayif1_testfile.funcubebin The operating frequencies for the spacecraft will be: Telemetry 145.940 MHz using 1k2 BPSK to the FUNcube standard. SSB/CW Transponder Uplink on 435.045 ? 435.015 MHz Downlink on 145.960 ? 145.990 MHz Initial operations of the spacecraft will be in a low power ?safe? mode where only the telemetry transmitter is activated. More details about the launch, exact deployment time and pre-launch TLE?s will be made available as soon as they become available; in the meantime we will really appreciate your support! [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- Nayif-1 UPDATE Pre-launch Keps and more details The launch time for the Nayif-1 CubeSat has been confirmed as 03:58UTC on February 15th 2017 on the PSLV C37 vehicle and a set of pre-launch TLEs have now been released: NAYIF 1 17002U 17002A 17046.17824931 0.00000000 00000-0 00000-0 0 9993 2 17002 97.5521 107.5843 0004848 278.6481 296.8511 15.21991390 01 This file can also been downloaded from here http://download.funcube.org.uk/nayif_tle.txt We expect that the FUNcube transmitter on Nayif-1 will activate at approximately 05:06UTC, but the exact timing is still to be confirmed! Initial transmissions will be in ?safe? mode and will be of the 1k2 BPSK telemetry only with approx 50mW of RF power. If the predictions are correct, the spacecraft will be heading north over Mexico and the western parts of the US and Canada. During the Launch and Early Operation phase (LEOP) of the mission, the Nayif-1 command team will be headquartered at the American University of Sharjah Ground station in the United Arab Emirates. They will obviously be especially keen to have all possible reports of signal reception during this first orbit! To encourage everyone to take part, there will be a small prize for the station that submits the first data to the Nayif-1 Data Warehouse and perhaps an extra reward if they manage to receive the very first frame transmitted by the spacecraft! This should have the sequence number 5471 or 5472. Details of the Nayif-1 frequencies, together with details of how to the download the Dashboard can be found here https://funcube.org.uk/2017/02/08/nayif-1-launch-date-now-confirmed/ The Data Warehouse is still under final development but a preview can be seen here: http://data.amsat-uk.org/nayif1/index Please note that if you are already a registered user of the FUNcube Dashboard then you do not need to re-register. Your existing details will transfer automatically to the new Dashboard when you run it for the first time. If you run the test file with the Nayif-1 Dashboard please do not expect the Warehouse to show the data - it is from an earlier date than that is already displayed. However the ?packets uploaded? tab at the bottom right corner of your Dashboard will show that the files have uploaded OK, that all is well with your system and that it is ready for action. We are hoping that the actual launch will be webstreamed and details of this will be made available as soon as possible. The AMSAT-UK and -NL team will also be using the #funcube IRC channel on launch day and you will be very welcome to join them there. If you do not have the Dashboard available then please submit your heard reports here. A web client can be found at http://irc.lc/freenode/funcube if you do not have an IRC client installed. [ANS thanks Graham G3VZV for the above information] --------------------------------------------------------------------- UT1FG/MM QSL Procedure for this season As you may know Yuri, UT1FG, prefers to do his own QSLs to the extent possible. He has asked me to help funnel QSL requests to him while he is at sea so that he can process them and mail them from ports as he travels. Yuri does not process qsl requests when he is not on a ship. The following procedure only applies to contacts made during this season from the M/V Chestnut. Previous seasons will be handled by his manager Eugene, UX0FY. Eugene has all the logs for previous seasons and can be contacted through his qrz.com email address. Please contact Eugene before sending anything in the mail to him and ask for instructions on how to proceed. You may prepare a logsheet of QSO's that Yuri can print, verify, sign and mail from one of his destination ports. An example of a suitable logsheet can be found at papays.com/sat under the UT1FG/MM QSL Instructions link at the top of the page. Please use the following conventions when preparing the logsheet: 1. List only one contact per grid. 2. Only request confirmations of NEW Grids. 3. Use Excel or a similar program to create the logsheet. 4. Save the Logsheet to a .pdf If your program cannot save to a .pdf, download a free program like Bullzip that will install a .pdf printer that you can print to and create a .pdf file. 5. Each page should stand alone; there should be a place for Yuri's signature on each page. 6. Incude your COMPLETE Mailing Address on each page. 7. Name the logsheet file with this format: Yourcall_UT1FG_DateLastQSO for example: DJ8MS_UT1FG_10Feb2017.pdf 8. Email your file as an attachment to: k8yse at papays.com with the subject line the same as the .pdf file name: DJ8MS_UT1FG_10Feb2017 10. Please be sure to follow the example on the website papays.com/sat/ut1fgqsl.html Consistency will help Yuri process requests more efficiently. 11. If there are qso's on your list that are not in the log, Yuri will draw a line through them and initial. I will send an acknowledgement email when I receive a request. This way you will know that Yuri will have your logsheet. If Yuri tells me that he has mailed your logsheet, I will post that information on the bulletin boards. Yuri's time when nearing or in port is very limited. He has a lot of responsibilities to carry out and large amounts of paper to process along with requests from his Company. He has more time when he is sailing. Let that guide you when deciding when you email your requests. A good time to mail your request is when Yuri is about 5 days from making port. Follow him at marinetraffic.com (M/V Chestnut - bulk Cargo). This new procedure may be changed or stopped depending on how it goes. Hopefully this will work well and Yuri will find it acceptable. We are very fortunate that Yuri operates from so many water grids that otherwise would never be on the satellites. His passion for satellites is amazing. Have fun working him.

I have Mode J doppler shift worked out-you start high in frequency, and the frequency lowers as the satellite moves towards you, and then away from you. For example, if I transmit in the exact center of the FO29 passband-145.950-the received signal from FO29 starts out above the center of the receive passband, around 435.859 or so at the beginning of the pass. When the satellite is overhead it is at the center of the passband-435.850, and then moves lower in frequency as the satellite moves away from me. This is assuming I keep the uplink frequency at 145.950 the entire time. Is it my imagination or is the situation reversed on Mode B. It seems that if I transmit on the center frequency of the uplink passband, the downlink signal is below the center at the beginning of a pass, and then moves up and ends up above the center of the downlink passband at the end of the pass-assuming I keep the transmit frequency the same. Is that correct? Why would Mode B behave differently than Mode J? You can see I still have some things to learn about the satellites. 73 John AF5CC From n8hm at arrl.net Tue Feb 14 03:50:01 2017 From: n8hm at arrl.net (Paul Stoetzer) Date: Mon, 13 Feb 2017 22:50:01 -0500 Subject: [amsat-bb] Mode B doppler shift question In-Reply-To: References: Message-ID: You are correct in your observation. The difference is that by tuning the higher of the two frequencies, you are canceling out much more of the Doppler shift since Doppler affects the higher frequency more. If you fix your transmit frequency on a Mode B satellite, you'll likely drift over other QSOs in progress.

Transceivers with CAT, or two rigs with CAT allow to implement this. I do this with a vintage FT-736, and QSO is just as a normal HF QSO, no tuning, hands free during all the pass, providing both stations use the same approach. There are very nice programs as SATPC32, Orbitron and others that allow do this. I use http://lu7abf.com.ar/pass.htm (the .exe part) along with wispDDE Driver. Using this, I see how transmit and receive Dopplers moves as the satellite passes, thus even not having CAT Control, one can manually correct Uplink/Downlink, allowing easily hear own return. To contact a station heard, Downlink frequency could be changed, application will show what Uplink to use. Wishing nice and rewarding contacts thru the birds. 73, LU7ABF, Pedro On Tue, Feb 14, 2017 at 12:50 AM, Paul Stoetzer wrote: > You are correct in your observation. > > The difference is that by tuning the higher of the two frequencies, > you are canceling out much more of the Doppler shift since Doppler > affects the higher frequency more.

The event is scheduled to begin at approximately 09:50 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and SV7APQ. The contact should be audible over Greece and adjacent areas. Interested parties are invited to listen in on the 437.525 MHz downlink. The contact is expected to be conducted in English. The 3rd Junior High School of Komotini is one of the 13 schools of Secondary Education that operate in Komotini, a city in the Region of Eastern Macedonia and Thrace, in the north-east of Greece. Our school is one of the oldest in the Municipality of Rodopi. The current building was constructed in 1992. Its a relatively new building with 16 classrooms, and laboratories for Computer Science, Physics, Chemistry, Biology, Music rooms, multiple-function rooms and a fully-equipped library. There are approximately 350 registered students (age 12-15), and 38 teachers of different fields in our school. One of the main characteristics of our school is its multi-cultural character. 25% percent of our students come from repatriated Greek families who lived for about a century in countries of the Former Soviet Union (Russia, Georgia, Armenia, Ukraine, etc) and came back to Greece in 1990 after the collapse of the regime in the countries of Eastern Europe. These students speak both the Greek and the Russian language fluently. 16% percent of our students are Muslims. The existence of a Greek Muslim minority in Thrace has been recognized internationally since 1922. Among them, there is a significant number of Pomaks and Roma students. There are integration classes for students with special educational needs and learning disabilities taught by teachers of Special Education. Additionally, every year many national educational programmes, such as Environmental Education, Health Education, Consumer Education and many Cultural programmes (music, dance, theatre, art, radio, astronomy) are implemented. Our school also has a very active cycling club. Students go on various educational trips every year, visiting other parts of Greece and expanding their learning skills and abilities. Participants will ask as many of the following questions as time allows: 1. What is the most challenging problem of living in space? 2. Can you see the moon closer from Earth, is it different? 3. How do you stabilize the food on the table? 4. How often do you do extravehicular activity? 5. Is it very difficult to become an astronaut? 6. Do you have sufficient oxygen in ISS? 7. If you had just one wish to become true for your job what would it be? 8. If a member of the crew is injured can you give him first aid? 9. When you come back to earth, is it easy for you to walk? 10. Which is the difference between day and night in Earth and in Moon? 11. What is the main target of your expedition? 12. Can you see meteor showers from space? 13. Have you ever seen a comet from space? 14. How long did the preparation for this expedition last? 15. How many hours do you work, do you have shifts? 16. What is the most extreme procedure of your expedition? 17. What is your favorite food in space? 18. How old were you when you decided to become an astronaut and what was the motive of your decision?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

I think you missed the question I was asking. I understand that people tune the uplink signal on Mode B, and the downlink signal on Mode J, where the 70cm band is the one being retuned. I was discussing where you never tune the transmitter, you stay on the same frequency, and the effect that doppler shift has on the downlink signal. To me it seems that the downlink signal, all by itself due to doppler shift, moves in different directions on the two different modes-it seems to decrease in frequency in Mode J as the satellite approaches you and then passes you, but seems to increase in frequency in Mode B when approaching you. Is that correct? 73 John AF5CC On Tue, Feb 14, 2017 at 3:50 AM, Paul Stoetzer wrote: > You are correct in your observation. > > The difference is that by tuning the higher of the two frequencies, > you are canceling out much more of the Doppler shift since Doppler > affects the higher frequency more.

If you fix your transmit frequency on an overhead pass of FO-29 at 145.950 MHz, your signal at the satellite at the beginning of the pass will appear to be 145.953 MHz. The transponder will retransmit your signal at 435.847 MHz, which will appear to you around 435.857 MHz. At the middle of the pass, your signal at the satellite will be at 145.950 MHz so the transponder will retransmit your signal at 435.850 MHz, and you'll receive it at 435.850 MHz. Say you fix your transmit frequency on an overhead pass of XW-2F at 435.340 MHz. Your signal at the satellite at the beginning of the pass will be around 435.350 MHz. The transponder will retransmit your signal at 145.980 MHz, which will appear to you at 145.983 MHz. At the middle of the pass, your signal at the satellite will be 435.340 MHz, the transponder will retransmit your signal at 145.990 MHz, and you'll receive it at 145.990 MHz. The reason for the difference is the different magnitude of the Doppler shift between the two bands (435 MHz having about triple the Doppler shift of 145 MHz), so, yes, a fixed transmit station will drift down on a Mode J satellite and up on a Mode B satellite. If you fix your transmit on Mode J, your signal will drift about 7 kHz on the transponder during an overhead pass, however on Mode B, your signal will drift about 20 kHz on the transponder. 73, Paul, N8HM On Tue, Feb 14, 2017 at 10:18 AM, John Geiger wrote: > Hi Paul, > > Thanks for the reply and your insight.

(437.500, 437.550, & 437.60) You need to adjust your tuning steps separately for TX and RX for Doppler correction. Your current configuration is taking to big of a step. Patrick WD9EWK made a list of 5 Doppler corrected frequencies which he stores in memory. As the orbit progresses over your QTH start with Memory #1 and work your way on up through the frequencies in memory. He has a graphic file of his frequency table posted at: https://twitter.com/WD9EWK/status/793644904916193281/photo/1 Patrick's recommended steps work well for me. I find I spend only a little time on memory slot 1 and slot 5. Memory slots 2, 3, 4 are what I end up stepping through most often during a pass. Also, packet routing add-ons such as WIDE, etc. are not needed. CQ VIA RS0ISS or CQ VIA ARISS keeps your packet short, less error prone, and more likely to be digipeated. I'll be looking for your callsign via the ISS (although toward the east I have a pretty big obstruction but I sometimes get through it). -- 73 de JoAnne K9JKM k9jkm at amsat.org From n8hm at arrl.net Tue Feb 14 19:06:02 2017 From: n8hm at arrl.net (Paul Stoetzer) Date: Tue, 14 Feb 2017 14:06:02 -0500 Subject: [amsat-bb] Having Issues with UISS/Soundmodem for ISS contacts..

As you can understand we are now getting to grips with the data flowing in and will need to make a few changes to the display portion of the application. This will entail stopping it a few times today as we make updates. The data collection part of the application will remain unaffected. If I have to stop that, your dashboards will back off until it becomes avaialble again. 73 Dave, G4DPZ From n4hf.philip at gmail.com Wed Feb 15 14:53:09 2017 From: n4hf.philip at gmail.com (Philip Jenkins) Date: Wed, 15 Feb 2017 09:53:09 -0500 Subject: [amsat-bb] Any current 2 meter usage by ISS? Message-ID: I'm one of the instructors for a Technician class course; I'll be teaching the specialized communication section (e.g. satellites, EME, APRS, fox-hunting) among other topics. I'd like to give those students who are already interested sat comms enough info so that they can start listening to ISS and the FM sats NOW; the specialized comms topic doesn't come up until a little more than midway through the course. As a teaser, I plan to give them the downlink frequencies from ISS and FM sats, explain tuning for doppler a little, and show them how to use the Pass Predictions page on AMSAT.ORG. I know that ISS packet is currently only on UHF (not VHF), but is the 2 meter voice frequency of 145.800 being used, either for random contacts by the astronauts, or for school contacts? None of them currently have packet/APRS gear, so I'm focusing only on voice contacts at least until the class ends (but I'll mention both of those when I do my more lengthy presentation in about a month). So, in short, my question is - is 2 meters being used at all right now for voice from ISS? If not, are random contacts being made on a UHF frequency? (I don't see a UHF voice downlink frequency listed in the 2016 "Getting Started with Amateur Satellites" book.)

Firstly, thank you for all the data, I have seen your call on the warehouse earlier. -298 frames and counting. This is my limited understanding...... The warehouse is totally happy with the data arriving from any souce i.e. different dashboards. Each frame transmitted from a funcube satellite or payload, includes a satellite identifier. This tells the warehouse the source of the data so it can store it appropriately. It also applies the correct decoding equations for the raw data transmitted The sequence and frame numbers are used to sort frames into correct order (some may be played back after a pass) they also prevents duplicates and set a time limit on when a particular frame will be accepted. If a dashboard for AO-73 receives data from Nayif-1 or UKube (or FUNcube-X) it will send it to the warehouse where the sat identifier is used to store it correctly. The issue is that the dashboard used at your QTH will only display the data correctly for the spacecraft it was intended for. Our hard pressed software team is working on a single dashboard for all the FUNcube satellites / payloads. It is a work in progress. This will be particularly useful when ESEO is launched as this satellite will have 1k2 and 4k8 bit rates and for another project which will transmit images. Please bear with us. So many things to do and so little time........... 73 David Gentlemen, Can I run both the Funcube AND the Nayif dashboard at the same time.

AMSAT will have a booth at the Yuma Hamfest in southwestern Arizona on Friday and Saturday, 17-18 February 2017. The hamfest will be at the Yuma County Fairgrounds, located south of the I-8 freeway along 32nd Street in Yuma, across the street from Yuma International Airport and Marine Corps Air Station Yuma. More information about the hamfest is available at: http://www.yumahamfest.org/ Once again, thanks to the Yuma Amateur Radio Hamfest Organization - a group whose sole purpose is to host this annual hamfest - for providing AMSAT a booth. This has become the largest hamfest in Arizona, drawing lots of hams from Arizona, Nevada, southern California, along with the snowbirds spending their winter somewhere in the deserts along the Colorado River. Hopefully there will also be some hams who come up from northern Mexico, which is only a couple of miles from the hamfest site. Along with the booth, there will be on-air demonstrations of satellite operating during the two days - weather permitting. If you hear WD9EWK on the satellites, including ISS and (if available) NO-84 passes, please call and be a part of the demonstrations. The hamfest site is in grid DM22qq.

I will head west for this weekend's Yuma Hamfest tomorrow night. Since I am not leaving earlier in the day, I don't plan on making stops along my drive from Phoenix. With that said, if I am making good time on the drive, I might stop to work a pass or two on the drive west. The best way to see what I'm doing is to look for WD9EWK-9 on APRS: http://aprs.fi/WD9EWK-9 I will spend most of my drive on the I-8 freeway through Arizona and a part of southern California tomorrow night, passing through grids DM22 and DM32. As of now, my plans are to return home sometime on Sunday (19 February). I don't have to drive the most direct route home, but that route would go back through the rarely-heard grid DM32. Or, based on some Twitter discussions a couple of weeks ago, I could make a long loop into southern California and work from grid DM13 once again. Or I could go north, heading back to the DM23/DM24 grid boundary - a place I operated from a couple of weeks ago. Any preferences? If so, please let me know by e-mail or at my @WD9EWK Twitter account. Thanks in advance, and 73!

AMSAT will have a booth at the Yuma Hamfest in southwestern Arizona on Friday and Saturday, 17-18 February 2017. The hamfest will be at the Yuma County Fairgrounds, located south of the I-8 freeway along 32nd Street in Yuma, across the street from Yuma International Airport and Marine Corps Air Station Yuma. More information about the hamfest is available at: http://www.yumahamfest.org/ Once again, thanks to the Yuma Amateur Radio Hamfest Organization - a group whose sole purpose is to host this annual hamfest - for providing AMSAT a booth. This has become the largest hamfest in Arizona, drawing lots of hams from Arizona, Nevada, southern California, along with the snowbirds spending their winter somewhere in the deserts along the Colorado River. Hopefully there will also be some hams who come up from northern Mexico, which is only a couple of miles from the hamfest site. Along with the booth, there will be on-air demonstrations of satellite operating during the two days - weather permitting. If you hear WD9EWK on the satellites, including ISS and (if available) NO-84 passes, please call and be a part of the demonstrations. The hamfest site is in grid DM22qq.

I worked AC0RA in Texas, AA5PK in Texas, NP4JV in Arizona, W5PFG in Texas, and WN9Q in Wisconsin from my QTH in southwest Washington, DC. I also heard KO4MA in Florida and NR0T in Minnesota. Signals were generally strong, with some fading at points. It seems to work at least as well as AO-73's transponder.

It was much easier than finding myself on an equivalent pass of AO-73.

Off course there is a challenge to add 104 spacecraft to the database in one go, and the whole swarm is still quite close together. We expect that Nayif-1 will be one of the last ones identified, as it is "only" a one Unit cubesat, and therefore has the lowest radar cross sectional area. So unless it separates from the rest quickly, it will be the smallest object of the lot. The main payload and the two secondary indian satellites have large radar cross sections, so have been identified already I would expect the Planet satellites to appear first, as they can do ranging to aid the orbit determination. So please keep using the pre-launch keps for now. We will update the BB when we believe that we have been detected. Off course, observations are most welcome. Precise TCA reports for instance will help in the determination of the timing of the orbit. Remember: there is no TLE lottery until all tickets are in the bowl ;) Thanks for all your participation so far, the Nayif-1 team appreciates it and is very impressed with our community!

Both sounding really good. I was using keps for 2017-008F (since they load automatically into Gpredict); seemed to work ok. I lost the bird a minute or two early, then realized that my rotor decided to swing around just at the wrong time, and it was too late to stop it. But even so, I'd say those keps are just a tad late, as both Bob and John had already found themselves and were chatting when I first got the rig and antennas configured. QSB was not much of a problem (operator issues were more severe :) ). I didn't check the telemetry side of things this pass. Equipment here is a Yaesu 847. 2m 2x8 element CP beam for receive, and 2x15 CP beam for transmit. No amps or preamps needed. Nice bird!

Following is my schedule for the weekend. As I mentioned on Twitter, I do pay attention to the "grids worked" maps you have on your QRZ web pages. As a result I am making a special detour to make FN17 available to a few who need it. A few of you even e-mailed me your maps. That's fine too! Send them to the e-mail address on my QRZ page. A few notes: - The weather forecast looks promising! I'm not likely to freeze or get buried in snow as long as I can keep the car on the road! - I have a long drive to FN27/28 on Saturday morning. Forgive me if I miss the first pass. - I will do my best to operate from the FN27/28 boundary, conditions permitting. If it's not safe then I'll have to do them separately. I don't know if I have cell service there. I'll announce where I will be if there is. - There are a few XW-xx "freight trains" in the schedule. We'll see how agile I can be! I'll try and keep up! - The usual disclaimers regarding obstacles like trees and geography that may block my signal. I may pack up early if there's no activity and I get bored. Get in there and work me. Snoozing = Losing Once you work me, please stand aside on subsequent passes and let others who need the new grid work me. I'll work you just to get you out of the way if you insist on being a pest, but I might forget to log you! :-) If you want to make a quick call and say hello then please wait until things quiet down and you hear me calling CQ. 73, Ken Alexander VE3HLS Friday Evening FN25 -------------------------- 17.02.2017 AO-73 01:10 17.02.2017 FO-29 02:25 17.02.2017 BY70-1 03:26 17.02.2017 EO-79 03:57 17.02.2017 FO-29 04:09 Saturday Afternoon FN27/28 -------------------------- 18.02.2017 EO-79 16:39 18.02.2017 FO-29 17:02 18.02.2017 AO-07 17:23 18.02.2017 AO-85 18:30 18.02.2017 AO-07 19:13 18.02.2017 AO-85 20:10 18.02.2017 AO-07 21:08 18.02.2017 XW-2D 21:34 18.02.2017 XW-2F 21:35 18.02.2017 XW-2B 21:39 18.02.2017 XW-2C 21:47 18.02.2017 XW-2A 22:37 18.02.2017 XW-2D 23:09 18.02.2017 XW-2F 23:09 18.02.2017 XW-2B 23:14 18.02.2017 XW-2C 23:23 Saturday Evening FN27/28 -------------------------- 19.02.2017 XW-2A 00:10 19.02.2017 AO-73 00:13 19.02.2017 AO-73 01:49 19.02.2017 FO-29 02:19 Sunday Morning FN17 -------------------------- 19.02.2017 AO-07 18:14 19.02.2017 AO-85 18:55 19.02.2017 AO-07 20:06 19.02.2017 AO-85 20:36 19.02.2017 XW-2D 21:22 19.02.2017 XW-2F 21:22 19.02.2017 XW-2B 21:27 19.02.2017 XW-2C 21:35 From k8bl at ameritech.net Fri Feb 17 02:55:46 2017 From: k8bl at ameritech.net (R.T.Liddy) Date: Fri, 17 Feb 2017 02:55:46 +0000 (UTC) Subject: [amsat-bb] EM30/31 Re-Schedule In-Reply-To: <771656376.272421.1487215188846@mail.yahoo.com> References: <771656376.272421.1487215188846.ref@mail.yahoo.com> <771656376.272421.1487215188846@mail.yahoo.com> Message-ID: <221923411.996847.1487300146210@mail.yahoo.com> New schedule is: 2/17 1542Z Pass SO50 1602Z Pass FO29 Bob K8BL/5 ----- Original Message ----- From: R.T.Liddy To: AMSAT BB ; Starcom Sent: Wednesday, February 15, 2017 10:19 PM Subject: EM30/31 Re-Schedule Due to a schedule conflict, I need to cancel my operation from EM30/31 on 2/16.

So yes, it will arrive earlier and earlier. Reason is that "slowing down" due to drag only makes the orbit lower. And lower means the orbit is smaller, and smaller means it gets to the same point sooner. Hence, it appears "faster" in time, but only because it is lower... Something like that... Bob -----Original Message----- A quick analysis, based on the doppler curve shown on the Dashboard and the Nova predictions using the latest TLEs, suggests that the spacecraft is presently approx 40-45 seconds ahead of the TLE predictions. Whether this is a?fixed offset? or whether this difference will change each day remains to be seen.

The drag at perigee reduces the total kinetic energy of the satellite, so when it continues it's orbit, it won't reach as high of an apogee.

Plan is to switch back to auto mode on Sunday 19 Feb 2017 pm UTC as usual. See https://funcube.org.uk/news/ for details of new FUNcube launched a few days ago, and Pls see below for other FUNcube transponder info Have FUN with the transponder. 73s Jim G3WGM and the FUNcube team. AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!) FUNcube-2 aka FUNcube on UKube The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/ All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

Any other suggestions out > there for an alternative to LMR-400?Thanks Frank KB2CWN Hello Frank, You could always consider a LNA at the antennas, which sets your system noise figure early on in the receive chain and allows the use of RG-8X or similar. It's best to buy a weatherproof LNA and mount it right at the antenna/rotator with a short section of high-quality, low-loss coax (or direct connect). You'll want to run DC up the coax to power the LNA, if possible. Make sure your LNA switches itself out of the way when you remove power! Of course, you'll lose power as heat on transmit with the higher-loss cable, but I wouldn't that is much of a problem with today's radio output levels. http://wb0dgf.com/preamp.htm Remember that you only need enough LNA gain to offset cable losses and your receiver's noise figure (NF). More than that risks overloading the front-end of your receiver and causing undesirable non-linear operation (IMD). A good place to start is about 13-15 dB of gain, if you need a concrete number. That's my view on it, and I'm definitely no expert. It works for me. YMMV. :-) --- Zach N0ZGO From kb2m at comcast.net Fri Feb 17 22:09:41 2017 From: kb2m at comcast.net (Jeff) Date: Fri, 17 Feb 2017 17:09:41 -0500 Subject: [amsat-bb] Kenwood D72A for sale In-Reply-To: <0D4272B5D938491E9B7CA06EEF666025@kb2m4PC> References: <0D4272B5D938491E9B7CA06EEF666025@kb2m4PC> Message-ID: <018FC1963D334A3984D924F11C9101A6@kb2m4PC> The D72 has been sold, thanks for all the interest.... 73 Jeff kb2m -----Original Message----- From: Jeff Sent: Friday, February 17, 2017 8:14 AM To: Amsat Subject: [amsat-bb] Kenwood D72A for sale I have a little used full duplex Kenwood TH-D72A for sale.It is in near perfect, unused condition.

But many people have problems with water accumulation in Belden 9913 type air dielectric coax so I don't recommend it. I switched to using LMR-400 and have been pleased with its performance in an installation that was up without problems for over 10 years. (Never had problems with it, just tore it all down after about 10 years to move from Minnesota to Texas!) As others have mentioned, LMR-400UF (Ultra-Flex) is an option for less stiffness in the rotator loops. Personally, I'd go ahead and use the regular LMR-400 and leave generous rotator loops, and you should be okay. That's how I put together my station in Minnesota and like I said, I had no problems with the coax in 10 years' time, before taking it all down to move to a new state. The Ultra-Flex version has noticeably greater loss than the regular LMR-400, especially in a 50-foot run on the 70cm (or higher) band. You might compromise by using LMR-400UF from the antennas to the rotator loops to just below the top of the tower, then change to regular LMR-400 from there to the rest of the 50 foot run to the radio location. You could even use a short piece of LMR-240UF for the rotator loop and then regular LMR-400 for the rest of the run, if you weren't comfortable with the stiffness of your loop. Good luck with your installation. 73 de W0JT/5, EL09vu20, AMSAT-NA LM On Fri, Feb 17, 2017 at 2:46 PM, Norm n3ykf wrote: > Belden 9913f7 > > On Fri, Feb 17, 2017 at 3:17 PM, Frank Staffa Jr. via AMSAT-BB > wrote: > > Hello everyone.

It also has some an unfortunate birdie which may or not affect you (436.7950). You could easily use some other UHF receiver or receiver chain with some work. Notably you may have to remove the de-emphasis circuit or bypass it by tapping into the discriminator directly; Some radios provide such already and then you could easily decode 9k6 GMSK in software. > > Jim > > wd0e at amsat.org > > jim at coloradosatellite.com > Diane VA3DB -- - db at FreeBSD.org db at db.net http://www.db.net/~db From ko6th.greg at gmail.com Sat Feb 18 17:06:55 2017 From: ko6th.greg at gmail.com (Greg D) Date: Sat, 18 Feb 2017 09:06:55 -0800 Subject: [amsat-bb] BY70-1 decay estimate In-Reply-To: <141fbbaf-ea74-1fa5-7b09-12f9eafdaed9@xs4all.nl> References: <9348335e-f4f2-1b3a-d536-123a91aad95a@xs4all.nl> <8b919221-beaa-d47d-778d-3d6713267816@xs4all.nl> <141fbbaf-ea74-1fa5-7b09-12f9eafdaed9@xs4all.nl> Message-ID: <7b210a2c-fd00-759e-9872-d8761b1a07fd@gmail.com> {sniff} Thanks for the confirmation.

Conductor migration is a problem with straight 9913, as well as other issues. Minimum bend radii need to be observed. PL-259 connectors can be applied to f7 with a plumber's torch. Amphenol N's are easy install and easy to come by. Do look for the 9913f7 compatible ones as the center conductor is heavier. I like Belden as quality is top notch. Flexible and long lived product. Keeping work in the US? Priceless. A 50' run is not much to worry about. Use LMR-400 DB (cost=free) for the 130' home run to the shack on VHF. It needs no preamp. On the UHF side, LDF450A does better, but needs a preamp. Try Craigslist for bits of cable. I dug 300' of LDF450A out of a dumpster. Still have 100'. Tomato or tomato. Do take care as workmanship rules the longevity and weatherproof qualities of the final product. All of this stuff works. Install with a hammer? Not for long.

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space).

DATE February 19, 2017 To All RADIO AMATEURS BID: $ANS-050.01 Nayif-1 Launched The Indian Space Agency ISRO successfully launched the amateur radio satellite Nayif-1 along with 103 other satellites, a record for a single launch. The PSLV- C37 lifted off from the Satish Dhawan Space Centre, Sriharikota, Andhra Pradesh at 03:58 UT on Wednesday, February 15, 2017. Nayif-1 started transmitting about an hour after launch and radio amateurs in the west of the USA reported the first signals. The first frame of data received at the Data Warehouse was from Christy Hunter KB6LTY. Telemetry data was also received by WA6FWF, KA7FVV, WC7V, NC7V, K6FW, KE7QPV, WA9ONY, W5PFG, KK6AYK. Ken Eaton GW1FKY reports he received his first frames of data when the satellite came in range of the UK at 10:07 UT. The satellite looks to be in perfect health and it was placed in autonomous mode before the end of the first day in orbit. Just like FUNcube-1, this mode has the spacecraft sending high power telemetry when in sunlight and with the SSB/CW transponder active when in eclipse. Already many contacts have been made through the transponder. As expected, the frequency stability of this spacecraft is much better than its predecessors. A new post-launch set of TLE?s has been issued by the launch authority and it can be downloaded from http://amsat-nl.org/download/NAYIF_TLE.txt Please note that these numbers are not based on JSpOC observations so we do not yet have a valid catalog number. During the Launch and Early Operation phase (LEOP) of the mission, the Nayif-1 command team have been headquartered at the American University of Sharjah Ground station in the United Arab Emirates. They have been very grateful for all the telemetry received from around the world. It has proven to be immensely useful to the team in checking that the spacecraft is functioning correctly. Our world-wide network has greatly impressed the many professionals that have been watching our activities. Already more than 100 ground stations are submitting data to the Nayif Data Warehouse. Please continue uploading the data as this will further enhance our knowledge about the spacecraft and the space environment through which it is traveling at 7.6 km/s. The Nayif-1 Data Warehouse has been updated and now includes the Whole Orbit, High Resolution graphs and the upload ranking. It also includes telemetry details from the ADCS sub-system ? this is called the iMTQ and is capable of actively magnetorquing. Over the coming days, we will be further tweaking the warehouse, so bear with us if it is unavailable for short periods of time. Background Nayif-1 has been developed by the Mohammed bin Rashid Space Centre (MBRSC) and American University of Sharjah (AUS). The UAE?s first Nanosatellite was developed by Emirati engineering students from AUS under the supervision of a team of engineers and specialists from MBRSC within the framework of a partnership between the two entities, aiming to provide hands-on experience to engineering students on satellite manufacturing. The spacecraft includes a U/V linear transponder and telemetry transmitter. It employs enhanced oscillator circuitry and includes an active attitude determination and control system. The operating frequencies for the spacecraft are: Telemetry 145.940 MHz using 1k2 BPSK to the FUNcube standard. SSB/CW Transponder Uplink on 435.045 ? 435.015 MHz Downlink on 145.960 ? 145.990 MHz The Nayif-1 Telemetry Dashboard can be downloaded from http://download.funcube.org.uk/nayif-1_Dashboard_1039_Installer.msi Guidance notes https://funcubetest2.files.wordpress.com/2017/02/nayif-1_dashboard_notes_release _1-0b.pdf A file to test that the Dashboard and Warehouse configuration are working correctly http://download.funcube.org.uk/nayif1_testfile.funcubebin Nayif-1 Data Warehouse http://data.amsat-uk.org/nayif1/ [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- Satellite Operators on the Road ZF, CAYMAN ISLANDS. Scott/KA9P and Ron/W9XS will be active as ZF2SC and ZF2FB, respectively, from the Cayman Islands between February 22-28th. Activity will be on 40/30/20/17/15 meters and the satellites. Operations will typically be CW, with a KX1 or KX3, and Buddipole beams or verticals. QSL via their home callsigns or LoTW. 6E, MEXICO. A group of Ham Radio operators from Southern Mexico will be operating from some Mayan archaeological sites from the Mexican States of Yucatan, Campeche, Tabasco, Chiapas and Quintana Roo, using the special callsign 6E3MAYA between March 18-21st. Activity is to commemorate the Spring Equinox which is so important for the Mayan culture. Activity will be on 80-6 meters on CW, SSB, the satellites and the Digital modes. QSL via XE3N. C6, BAHAMAS (IOTA Op). Operators John/M0IDA, Rob/M0VFC and Steve/M1ACB hope to be active as C6APY from Little Harbour Cay, Berry Islands (NA-054, WW Locator FL15do). They will fly into the Bahamas on March 2nd, but it will take them a couple of days to get to the island, so they hope to be active around March 4th - but this is very much weather dependent, as is the whole operation. They will fly back to the UK on March 12th, which means they will need to de-rig on the 10th or 11th, again varying according to the weather. Operation probably won't be 24/7 - they will do as much operating as they can, but eating and sleeping is back on the boat, there's only three of them, and they will probably want to go for the occasional swim as well. They will be running up to three stations simultaneously, all Elecraft K3s at 100W. They will be generator powered and have to carry the full week's fuel with them on the boat, hence no amps. They are expecting that most QSOs will be on 40-15 meters; they will monitor the higher HF bands as well and may venture on to 10/12m if propagation favors them; similarly they may throw up an 80m dipole, but don't expect to do very much, if anything, there. There will definitely be CW (op M0VFC) and SSB (ops M0IDA and M1ACB); they may also do some data if time permits. They should be active on some satellite passes with hand-held antennas: the FM birds will only cover parts of the USA, and not EU, so they will attempt some FO-29 passes as well. They are not satellite experts though, so be patient with them. QSL is via M0OXO's OQRS system. They will upload the logs to ClubLog and LoTW regularly throughout the trip, assuming all the kit plays nicely.

This radio will replace the Ericsson radio that failed a few months ago. The VHF radio is used for school group contacts and amateur packet radio in the Columbus module. Once the Dragon vehicle is berthed to ISS, the Ericsson will be unstowed and, at some point, installed in Columbus, replacing the UHF radio that is now supporting APRS packet and some school contacts. Our thanks to SpaceX on an outstanding and historic flight from Kennedy Space Center's Launch Pad 39A, where many Space Shuttle missions and nearly all the Apollo moon missions were launched. We also would like to thank our ARISS benefactors-NASA and CASIS, the Center for the Advancement of Science in Space. And, of course, our amateur radio long-time sponsors-our national amateur radio organizations around the world, including the American Radio Relay League (ARRL) in the US, and our international AMSAT organizations, including AMSAT-NA. Before closing, I want to let you know that ARISS is making great progress on the development of the new interoperable radio system that we hope to use to replace our aging radio infrastructure in the Columbus module and the Service module. The hard (and expensive) part of this effort is just beginning, with testing and human certification on the horizon. We thank all that have donated to the cause thus far. We hope you continue to help ARISS move forward through your support, including your volunteer time and talent and, of course, financial contributions through the AMSAT web site donate button. 73 es Ad Astra!

We have produced a new set of unofficial TLEs that take into account the new AOS / TCA / LOS timings. Please however note that the post-launch TLEs do not contain the correct constants to make this TLE reliable in the long run. The only object that comes close in the recent TLEs from JSpOC is the 2017-008F object, but note that we are still missing a lot of objects. They are working round the clock to map and catalog all remaining objects, but 104 satellites presents a challenge. We are in contact with JSpOC about this and are doing our best to help them match up objects. For now, the unofficial ones are: NAYIF-corrected 1 17003U 17002A 17046.17714120 0.00000000 00000-0 00000-0 0 9994 2 17003 97.5521 107.5843 0004848 278.6481 296.8511 15.21991390 02 and 2017-008F-corrected 1 17004U 17008F 17050.08273148 .00155491 00000-0 65272-2 0 9998 2 17004 97.5078 111.7095 0000538 25.3680 334.7132 15.22769132 566 And we welcome any observations with regard to which one you used and how much it was off.

I read that at the very least putting one on the 70cm antenna will help a lot with the receive. But, I just can not find any. Most of the names I came across must have went out of business because their website are no longer in existence. ?Any suggestions out their from you season operators out there? The ones that I got last post I couldn't find.?Thanks Sent from Yahoo Mail on Android On Fri, Feb 17, 2017 at 3:17 PM, Frank Staffa Jr.> wrote: Hello everyone. I just purchased a M2 leopack antenna system and I was reading about different coax cables to use for low loss. Since I am mounting the antenna only about 10 feet off the ground, 50 foot will be enough to go into the shack. I wanted to purchase RG8x but read that the best way to go is with LMR400. What I dislike about it is that its much wider and very stiff, and will make it difficult around bends. I also have the Az/alt rotator which I will have to loop each antenna to have enough for turns. Any other suggestions out there for an alternative to LMR-400?Thanks?Frank KB2CWN? Sent from Yahoo Mail on Android Frank, I went through the same thing you did. I am running a Kenwood TS-790 (so about 30 watts max) and have about 100 feet of feedline so I need preamps on both 2 meters and 70 cms. I looked and the recommendations you have already received are great but I ended up going with these: http://vhfdesign.com/en/category/lna I found that they were less expensive that some of the others and they would handle my power requirements. They have RF protection but I think most folks would say that you still might need to use a sequencer or just an on/off switch depending on the band you are receiving on (that is the mechanism I went with- I just switch the transmit band preamp off (thus it is bypassed) using a simple switch in the shack). They would probably be fine for FM but for SSB it is not worth taking the chance (I switch them religiously). You could also use the simple sequencer they sell. That is my next project. I have been very pleased with them but have only had them in place for a few days. The company was very responsive to my questions via email and I was a bit of a pain when I bought them because they appear to be a new(ish) company. Good luck and have fun!

An astronaut on the International Space Station looks back at Earth and sees the beauty and diversity of life. They imagine humans of all colors and creeds finding common ground and getting ready for tomorrow. Our school mirrors that ideal in microcosm. Our school is in North America, in the United States, with latitude of 44? N. John Glenn Middle School is proud to stand in Maplewood, Minnesota ever since it opened in 1962. Generations of citizens have been educated within our walls. Today, parents and grandparents come to conferences to support their student and fondly say, "I remember this classroom." The neighborhoods have grown but the family ties remain the same. Our students have come together from different nations, cultures, and personal histories. They speak approximately 35 different languages. They find faith in many different religions. Some of us are temporarily out of our homes. Some of our families are hurting financially. Thankfully, all of us have the chance for a bright future. Our principal, Jill Miklausich, guides us to collaborate in learning and problem solving. She encourages us to band together and reach for the stars. Together our students of all colors and creeds, face adversity, and get ready for tomorrow. Our school embraces the fearless sense of adventure made famous by our namesake, Colonel John Glenn. When we make the call to the International Space Station please know that our hearts and minds are filled with excitement and infinite possibilities. At John Glenn, we celebrate life! Participants will ask as many of the following questions as time allows: 1. How do you handle an acute illness like one that needs an operation or immediate help? 2. What do you do in your free time if you have any? 3. What kind of medical testing does an astronaut have to go through to be physically and mentally fit for duty? 4. What are the difficulties when it comes to being clean, eating food, and engineering in space? 5. How important is team work to the mission of the ISS crew? 6. What is your favorite piece of research you have done and how is it impacting our future? 7. When you go up in space, do you feel the loss of home or when you come back, do you miss sleeping under the thousand stars? 8. How does the International Space Station benefit humanity? 9. Can people with disabilities go in space? 10. What happens if the space station breaks down? 11. Do you have any games or electronics you use? 12. Where could WiFi be in space and cellular connection for phones? 13. What is the best thing you've seen in space? 14. What was going through your mind during your first orbit? 15. Have you made any cool or new discoveries on the ISS? 16. How do you send written messages from Earth to the ISS?

In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Similar boom lengths. Now when vertically polarized and stacked side by side as in the top picture how close can they get to each other before starting to mess with each other. Same thing in next image but horizontally polarized so above and below each other. Now if they are 90 deg in rotation IE: one is vertically polarized and the other horizontal, I'm thinking they could even be on the same boom correct? So that brings in the third drawing same antennas but at 45 deg to the horizon but 90 to each other, How close can they get without bugging the other? Now with the 45 deg angle thing, how much will a metal cross boom mess with them?

They will also, without the operator having to take any particular action, upload that data correctly to the data warehouses and these uploads will be correctly recorded on the "Upload Ranking" tab. The use of the "wrong" Dashboard when uploading data to the Warehouse causes the no problems:) Although the FUNcube dashboard will display data from the other two spacecraft, and vice versa, much of the data is invalid as the tlm sequences and some of the formats are different between the various spacecraft. We are presently working on two Dashboard upgrades: A) creating a "Display the tlm ONLY from the satellite specific to the particular Dashboard in use" tickbox to select. This will mean that, for instance, the FUNcube-1 dashboard will not display or store Nayif-1 data. This will ensure that all the graphs etc only relate to FUNcube-1. Again thsi would not stop the software decoding tlm from one of the other spacecraft and forwarding it to the Data Warehouse. B) creating a single Dashboard which combines all the existing ones into one "unified" version. We cannot at this time confirm when either of these "upgrades" will be available but we appreciate their importance.....

I read where I can put both of my Cushcraft 3-element Yagis together, spacing the elements on one so that they are ahead or behind the other set of elements. Then binding the two Yagi booms together. Feed line would be one 1/4 wave and one 1/2 wave, "I think". Then the two feed lines would be soldered together and attached to a PL-259. I put a couple of photos of my construction project on the AMSAT Facebook page, but it only shows the 70cm Cushcraft Circularly Polarized Yagi at one end of the cross-boom and a single 3-element Cushcraft Yagi at the other end of the cross-member. I originally placed the second 2-m Yagi at a 1/4 wavelength away from the end Yagis, but saw some pretty high SWR readings on both the 70cm and on both 2-m Yagis. This is more difficult to explain in writing than to actually do. I will get some photos up to my Ham Radio DropBox account and post the link here, "real soon now". Photos here might be more illustrative than my written explanation (pun intended). I appreciate all of the comments and other advice received here and on the Facebook AMSAT page. ------------------------- Esto es para mis amigos de habla hispana: La misma pregunta aqu?, RE colocando los dos Yagis 2-M directamente al lado del otro y ?ngulos de 90 grados. Le? donde puedo poner ambos de mis Cushcraft de 3 elementos Yagis juntos, espaciando los elementos en uno para que est?n por delante o detr?s del otro conjunto de elementos. Luego se unen las dos barras de Yagi. La l?nea de alimentaci?n ser?a una onda 1/4 y una onda 1/2, "creo". A continuaci?n, las dos l?neas de alimentaci?n se soldar?an juntas y se unir?an a un PL-259. Puse un par de fotos de mi proyecto de construcci?n en la p?gina de Facebook de AMSAT, pero s?lo muestra los 70cm Cushcraft circularmente polarizado Yagi en un extremo de la cruz-boom y un solo 3-elemento Cushcraft Yagi en el otro extremo de la cruz- miembro. En un principio coloc? el segundo 2-m Yagi a una longitud de onda 1/4 lejos del extremo Yagis, pero vi algunas lecturas bastante altas de SWR en ambos los 70cm y en ambos 2-m Yagis.

I didn't realize that its high spin rate may be some of the issues I'm having with it. I basically can't get reasonably consistent reception long enough to possibly complete a QSO ! I've been able to copy my own downlink OK at times and using DopplerPSK with no issue. And I have copied your call a number of times. Does NO-84 go into a "low-power" mode when it is in eclipse ? My antenna is limited to an "Alaskan Arrow" which is rotor mounted on my roof and tracks the satellite. Using an IC9100 and an inverted L for the uplink antenna. Hopefully condx will improve, as this is a very interesting satellite !

The event is scheduled to begin at approximately 08:31 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between FX0ISS and F4HHV. The contact should be audible over France and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in French. We are two small schools in pretty twin villages in the South of France, Boissi?res and Saint-Dionisy. Enjoying very beautiful surroundings, we are located just 15 km from N?mes and 40 km from Montpellier, in the Occitanie region, on the threshold of the Camargue wetlands and the Cevennes mountain range. Our villages are nestled at the foot of a hillside covered with evergreen oak trees, juniper bushes, thyme, "capitelles" (dry-stone cabins) and with a well-preserved "oppidum" (iron-age settlement) at its summit. >From the top, one can marvel at the splendid view over the plain of Vaunage (stretching between Caveirac and Calvisson), the Pic Saint Loup and the Mediterranean Sea on the horizon, and to the recognisable architecture of the Grande Motte (seaside town). On a clear day, one can even discern the peaks of Mont Loz?re, Mont Aigoual and Mont Ventoux. Our two little schools, served by a single school-bus-run, work closely together within an inter-town educational grouping ("Regroupement P?dagogique Intercommunal") and maintain a privileged relationship with all of the children. The Boissi?res school welcomes 61 pupils from infants ("maternelle") to first grade ("Cours Pr?paratoire") - in three classes and the Saint-Dionisy school receives daily 73 children from second grade ("Cours El?mentaire 1re Ann?e") up to fifth grade ("Cours Moyen 2e Ann?e") - also in three classes. The pupils are delighted to work together on a common theme between the two schools. They are charmed by this wonderful project of being able to communicate with Thomas Pesquet from space. They have been carrying out lots of learning work and are making discoveries about astronomy, the International Space Station and communication. We can be sure that many are already dreaming of becoming the next Thomas Pesquet! Participants will ask as many of the following questions as time allows: 1. Est-ce qu'il fait nuit dans l'espace? 2. Qu'est-ce qui a ?t? le plus difficile dans ta pr?paration? 3. Est-ce que la Terre est belle vue de l'espace? 4. A quoi as-tu pens? juste avant le d?collage? 5. Est-ce que tu manges bien? 6.

Es-tu press? de revenir sur Terre? 19. Comment es-tu habill? dans la station? 20. As-tu d?j? vu passer une m?t?orite par une fen?tre de l'ISS? Translated: 1. Is it dark in space? 2. What was the hardest thing in your training? 3. Is the Earth beautiful from space? 4. What did you think just before liftoff? 5. Do you eat well? 6. You fulfilled your dream...so what do you dream about up there? 7. Is it good to be in space? 8.

We can be found at Amateur Radio on the International Space Station (ARISS). To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD About ARISS: Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Our villages are nestled at the foot of a hillside covered with evergreen oak trees, juniper bushes, thyme, "capitelles" (dry-stone cabins) and with a well-preserved "oppidum" (iron-age settlement) at its summit. >From the top, one can marvel at the splendid view over the plain of Vaunage (stretching between Caveirac and Calvisson), the Pic Saint Loup and the Mediterranean Sea on the horizon, and to the recognisable architecture of the Grande Motte (seaside town). On a clear day, one can even discern the peaks of Mont Loz?re, Mont Aigoual and Mont Ventoux. Our two little schools, served by a single school-bus-run, work closely together within an inter-town educational grouping ("Regroupement P?dagogique Intercommunal") and maintain a privileged relationship with all of the children. The Boissi?res school welcomes 61 pupils from infants ("maternelle") to first grade ("Cours Pr?paratoire") - in three classes and the Saint-Dionisy school receives daily 73 children from second grade ("Cours El?mentaire 1re Ann?e") up to fifth grade ("Cours Moyen 2e Ann?e") - also in three classes. The pupils are delighted to work together on a common theme between the two schools. They are charmed by this wonderful project of being able to communicate with Thomas Pesquet from space. They have been carrying out lots of learning work and are making discoveries about astronomy, the International Space Station and communication. We can be sure that many are already dreaming of becoming the next Thomas Pesquet! Participants will ask as many of the following questions as time allows: 1. Est-ce qu'il fait nuit dans l'espace? 2.

We can be found at Amateur Radio on the International Space Station (ARISS). To receive our Twitter updates, follow @ARISS_status Next planned event(s): TBD About ARISS: Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), the Center for the Advancement of Science in Space (CASIS) and National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio.

Dave's 3 element 2m beam doesn't quite qualify. Joe, you're probably ok, but still... I'd put them as far apart as is practical, and not worry so much about the math. How long is your cross arm? 6 or 8 feet? Start there. These are relatively blunt instruments; don't over-think it. :) To Joe's numbers, two of the 65's would be placed 65 (what, inches?) apart, or about 5'. By the ideal different bands diagram, the mixed pair would be half of 65 plus half of 123, or 94 apart, or about 8'. But the different bands practical diagram says, basically, anything farther than half of whichever is the higher band's distance, so if that's the 123 antenna, about 5'. So, like I said, 6-8 feet is probably fine.

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS.

You made ( or someone) made a comment about 10 meters screwing up NO-84. Does it really attenuate it that much? I have been playing with NO-84 for quite a while. Reason asking is My 10 meter side has been no problem, even 5 watts, is enough to activate her. My weak side has been the recv. But Sunday I put together a 70 cm 9 ele beam and listened and on both passes not only was it full quieting it was FULL SCALE!! Then at the Monday passes this I was ready for transmit too.

ARISS thanks everyone in advance for their assistance. Feel free to send your reports to aj9n at amsat.org or aj9n at aol.com. **************************************************************************** *** Message to US Educators Amateur Radio on the International Space Station Contact Opportunity Call for Proposals Proposal Window February 15 ? April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS. For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Sessions go to http://www.arrl.org/hosting-an-ariss-contact.

Or Possibly it is the other way around? Where the PSK is what gets shut off? Reason asking is My 10 meter side has been no problem, even 5 watts, is enough to activate her. My weak side has been the recv. But Sunday I put together a 70 cm 9 ele beam and listened and on both passes not only was it full quieting it was FULL SCALE!! Then at the 00Z pass this evening I was ready for transmit too. I listened first and heard nothing, about mid way I started transmitting, and nothing at 5 watts, 20,, 50 and even 100 not once did she come awake. Does this happen?

Or Possibly it is the other way around? Where the PSK is what gets shut off? Reason asking is My 10 meter side has been no problem, even 5 watts, is enough to activate her. My weak side has been the recv. But Sunday I put together a 70 cm 9 ele beam and listened and on both passes not only was it full quieting it was FULL SCALE!! Then at the 00Z pass this evening I was ready for transmit too. I listened first and heard nothing, about mid way I started transmitting, and nothing at 5 watts, 20,, 50 and even 100 not once did she come awake. Does this happen?

Thanks for this explanation. I was wondering why the Superview satellites were in stable near-circular orbits at ~520 km if the launch vehicle malfunctioned.

The highest will be for the period between the last two sets before decay, which have epochs: Fri Feb 17 17:37:01.530336 2017 UTC Fri Feb 17 22:00:25.286112 2017 UTC i.e., roughly 4.5 hours apart. The specific orbital energy at the first epoch was -3.044e7 J/kg and -3.054e7 J/kg at the second. The energy decreased by 100 kJ/kg during this time, so over 4.5 hours that's an average of about 6.2 watts per kilogram. Multiply that by the (unknown?) mass of the spacecraft to determine the actual drag power dissipation in watts. Depending on how much of that heat was conducted into the spacecraft, I suppose it would have shown up as a temperature increase in telemetry but not necessarily enough to cause the electronics to fail. Decay was about 2.25 hours after the last eleset, and obviously the power dissipation rose quite sharply toward the end of that interval...

There's the Karman Line that many people consider the traditional "edge of space", set quite arbitrarily to a nice round 100 km. But even a satellite at, say, 500 km will come down in a number of years because it's already re-entered the atmosphere and losing energy to air drag. (Strictly speaking, you could say that it never "re-enters" the atmosphere because it never left it in the first place.) Karman reportedly chose 100 km as about where an aircraft moving at orbital velocity would be just barely able to generate enough lift to support its own weight. I.e., that would be the highest altitude conceivably reachable with a winged aircraft. I'm not sure how he got that result since it would depend on the size and shape of the wings, the aircraft weight, etc. And of course no real aircraft can get *anywhere* near 100 km with lift, to say nothing of achieving orbital velocity with current aircraft propulsion. (Even with a rocket engine Space Ship One could only briefly visit space; it had only about 4% of the energy needed to attain a minimal orbit.) >From memory, most meteors and decaying spacecraft break up below the Karman line, in the mesosphere at maybe 70-80 km. The mesosphere is the hardest region of the atmosphere to study since it's too high for balloons and too low for satellites. It can only be briefly visited with sounding rockets (or well protected re-entering spacecraft.) So I can't give you an exact altitude, but I could say that an object "stops orbiting" when its vacuum perigee (i.e., its projected trajectory if you ignore the atmosphere) goes negative. As long as the vacuum perigee is positive you could say that the satellite is still in orbit, if not for long given the rate at which it's losing energy to drag (and causing the instantaneous vacuum perigee to decrease). And that assumes the spacecraft remains in one piece. Just before re-entry, Apollo 11 was in a highly elliptical earth orbit with a vacuum perigee of 38.5 km. But it lost so much energy to drag that its vacuum perigee went negative well before it could reach that original 38.5 km point. Had the vacuum perigee been too high, then when it got to perigee it would have retained enough energy to fly back out into space. Mike Collins wrote in his book that he carefully monitored total spacecraft energy during entry, and he breathed a huge sigh of relief when it fell below that required to maintain an orbit. > #2, in the case of a spacecraft with radio TX capability, should we > expect it to stop transmitting at some point prior to actual re-entry > (for some electrical or RF reason) or do objects normally keep > transmitting until they fail structurally due to heat & mechanical > break-up? Well, that depends on how much of the drag heat gets into the electronics and whether they get too hot to function before structural failure. The air is so thin in the upper mesosphere and the velocity is still so high that heating effects probably overwhelm aerodynamic forces, so initial structural failure probably comes from melting, not mechanical pressure. --Phil From AJ9N at aol.com Fri Feb 24 09:13:32 2017 From: AJ9N at aol.com (AJ9N at aol.com) Date: Fri, 24 Feb 2017 04:13:32 -0500 Subject: [amsat-bb] Upcoming ARISS Contact Schedule as of 2017-02-24 09:00 UTC Message-ID: Upcoming ARISS Contact Schedule as of 2017-02-24 09:00 UTC Quick list of scheduled contacts and events: ABOUT GAGARIN FROM SPACE, Space Odyssey Project, Krasnoyarsk, Russia, direct via RV?ADW (***) The ISS callsign is presently scheduled to be RS?ISS (***) The scheduled astronaut is Andrei Borisenko (***) Contact is a go for Sat 2017-02-25 08:36 UTC (***) Ecole primaire Elie Desplan, Boissi?res, France and Marie Castang, Saint Dionisy, France, direct via F4HHV The ISS callsign is presently scheduled to be FX?ISS The scheduled astronaut is Thomas Pesquet KG5FYG Contact is a go for: Sat 2017-02-25 13:14:15 UTC 58 deg (***) ABOUT GAGARIN FROM SPACE, Raduga Space Communication Center of St. Petersburg, Russia, direct via RA1AJN (***) The ISS callsign is presently scheduled to be RS?ISS (***) The scheduled astronaut is Sergey Ryzhikov (***) Contact is a go for Sun 2017-02-26 09:15 UTC (***) Ecole Albert Camus, Rueil-Malmaison, France, College Marcel Pagnol, Rueil-Malmaison, France, and Ecole ?Robespierre B.?, Rueil-Malmaison, France, direct via F6KFA The ISS callsign is presently scheduled to be FX?ISS The scheduled astronaut is Thomas Pesquet KG5FYG Contact is a go for: Wed 2017-03-01 08:04:44 UTC 77 deg Student Space Technology Association, Knoxville, TN, direct via AA4UT The ISS callsign is presently scheduled to be NA1SS The scheduled astronaut is Shane Kimbrough KE5HOD Contact is a go for: Wed 2017-03-01 19:08:03 UTC 49 deg **************************************************************************** ** ARISS is always glad to receive listener reports for the above contacts.

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS.

Assuming a flight to GTO was available to a 1U or 3U cubesat, if the perigee is not raised the satellite will not stay in orbit very long, if I understand it correctly. Given the limited size of the spacecraft and the prohibition on volatile propellants this poses a difficult challenge. It would be interesting to determine if enough thrust can be generated by electrical thrusters to accomplish this ? - Howie AB2S ________________________________ From: AMSAT-BB on behalf of Phil Karn Sent: Friday, February 24, 2017 12:53 AM To: amsat-bb at amsat.org Subject: Re: [amsat-bb] BY70-1 Here's a first calculation of the power dissipation in BY70-1 during its decay. The highest will be for the period between the last two sets before decay, which have epochs: Fri Feb 17 17:37:01.530336 2017 UTC Fri Feb 17 22:00:25.286112 2017 UTC i.e., roughly 4.5 hours apart. The specific orbital energy at the first epoch was -3.044e7 J/kg and -3.054e7 J/kg at the second. The energy decreased by 100 kJ/kg during this time, so over 4.5 hours that's an average of about 6.2 watts per kilogram. Multiply that by the (unknown?) mass of the spacecraft to determine the actual drag power dissipation in watts. Depending on how much of that heat was conducted into the spacecraft, I suppose it would have shown up as a temperature increase in telemetry but not necessarily enough to cause the electronics to fail. Decay was about 2.25 hours after the last eleset, and obviously the power dissipation rose quite sharply toward the end of that interval...

Plan is to switch back to auto mode on Sunday 26 Feb 2017 pm UTC as usual. See https://funcube.org.uk/news/ for details of new FUNcube launched last week, and Pls see below for other FUNcube transponder info Have FUN with the transponder. 73s Jim G3WGM and the FUNcube team. AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Low temperatures give higher freqs!) FUNcube-2 aka FUNcube on UKube The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regular-operation/ All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL.

Latest was 6-turn feed for an offset feed dish to receive AO-40 on 2401 MHz. But back in 1996 I built a 14-turn 437 MHz helical beam to try to hear MGS at 10M km from Earth. Did not finish the 437 converter in time but did try out the helical beam on uplink and found it not near as good as my M2 436CP42UG (not surprisingly). I used flat brass strip to match 140 natural impedance of a helix to 50-ohms. The length was 1/4 wavelength and spacing from the ground plane reflector varied from direct connection to the flange-mount N-connector to about 3 times further at the connection to the starting turn of the helix. Easy to tune by varying that distance for best match. I think 2m is the lowest frequency I would make a helical beam. That 20-MHz monster that MIchael links to - well I think I would rather make a x-yagi (which would permit using either RHCP or LHCP). Most amateur Jupiter radio astronomers only use a crossed dipole antenna. 73, Ed - KL7UW Date: Fri, 24 Feb 2017 12:21:32 +0200 From: Michael Fletcher To: amsat-bb at amsat.org Subject: Re: [amsat-bb] Helical Antenna for 2-meters > I just did some calculations from the ARRL Antenna Handbook. > I came up with a 6-turn helical with a diameter of 25.826" and > a length of 121.65".

Otherwise, things are much more complicated with a chemical or electrical rocket because you have to carry your reaction mass with you and then put energy into it to blow it out the nozzle at high speed. There's a fundamental tradeoff in rocketry between rocket power and propellant mass flow rate. You can produce a given amount of thrust with high power and a low propellant mass flow rate, or with low power and a high propellant mass flow rate. E.g., to produce a thrust of 1 N with a mass flow rate of 1 kg/s, you have to eject it at 1 N / 1 kg/s = 1 meter/sec. Ignoring relativity, the kinetic energy in 1 second of exhaust (1 kg) will therefore be 1/2 mv^2 = 1/2 * 1 kg * (1 m/s)^2 = 0.5 joules and since you need 0.5 joules every second, the required power will be 0.5 watts (assuming 100% efficiency). If you double the exhaust velocity to 2 m/s, you can drop the mass flow rate to only 1/2 kg/s and still get 1 N of thrust (1/2 kg/s * 2 m/s = 1 N). But you'll now need a power of 0.5 * 0.5 kg/s * (2 m/s)^2 = 1 watt i.e., twice as much power for that same 1 newton of thrust. So, which do you have more of, propellant mass or energy? In a chemical rocket the energy is stored in the unburned propellant, so the energy per unit mass is set by the propellant chemistry. That's why every propellant combination has a theoretical specific impulse, e.g. 455 seconds for hydrogen/oxygen in vacuum. Specific impulse is just effective exhaust velocity divided by g = 9.8 m/s^2, so the theoretical exhaust velocity for hydrogen/oxygen is 4,462 m/s. But in an electric rocket the energy source is external to the propellant mass, so the energy/mass ratio can vary; you decide how fast to eject it. If mass is cheaper than energy, then you want a low exhaust velocity. If energy is cheaper than mass, then you want a high exhaust velocity. Since the rocket is free to move, the kinetic energy it produces will be split between the payload/rocket itself (which you want) and the exhaust (which is effectively wasted). The only way to get 100% of the energy into the payload/rocket and none into the exhaust is to set the exhaust velocity equal to the current velocity of the rocket so that the exhaust comes out stationary. Of course, velocity is relative so you measure it relative to the reference frame in which the rocket is initially stationary. So to minimize energy consumption you want to increase the exhaust velocity as the rocket accelerates. That's the exact idea behind the VASIMR (Variable Specific Impulse Magnetoplasma Rocket). The recent "EM drive" hype notwithstanding, I know of only one way to produce thrust in vacuum without some kind of propellant: the photon rocket. Even a flashlight will work, but let's do the numbers. The momentum of a photon is equal to its energy divided by the speed of light, so to get 1 newton of thrust from a 100% efficient photon rocket requires a power input of 1 N * c = 300 megawatts! That kind of power in space requires either a very large solar array or a very big nuclear reactor (which still needs a very large radiator to reject waste heat). But there's a simpler way to power a photon rocket with the sun. Instead of turning solar photons into electricity and back into photons, why not use solar photons directly? Voila -- that's what a solar sail does. The thrust produced by a solar sail per unit area is equal to the incident solar power per unit area divided by the speed of light. At 1 AU that's about 1361 W/m^2, so the thrust will be 1361 W/m^2 / c = 4.54 micro newton/m^2. That's actually units of pressure, so solar radiation pressure at 1 AU is 4.54 micropascal on a sail normal to the sun that simply absorbs solar photons. If you reflect them back, you'll get twice as much, 9.08 micropascal. Doesn't seem like much, but you'll get it continuously, no local power source or propellant mass needed. The one big problem with solar sails is that you can't use them in low orbits because they'll generate far more drag than thrust. 73, Phil From dave at g4dpz.me.uk Sat Feb 25 09:36:04 2017 From: dave at g4dpz.me.uk (David Johnson) Date: Sat, 25 Feb 2017 09:36:04 +0000 Subject: [amsat-bb] Nayif-1 Orbit Predictions on Data Warehouse Message-ID: Hi, With thanks to Chip, N2YO, we now have graphical orbit predictions for Nayif-1: http://data.amsat-uk.org/nayif1/satpos.html 73 Dave, G4DPZ From wouterweg at gmail.com Sat Feb 25 09:52:32 2017 From: wouterweg at gmail.com (Wouter Weggelaar) Date: Sat, 25 Feb 2017 10:52:32 +0100 Subject: [amsat-bb] NAYIF-1 TLE Message-ID: Hi All, JSpOC has released a new set of TLEs, which now contains additional objects.

School presentation We are two small schools in pretty twin villages in the South of France, Boissi?res and Saint-Dionisy. Enjoying very beautiful surroundings, we are located just 15 km from N?mes and 40 km from Montpellier in the Occitanie region, on the threshold of the Camargue wetlands and the Cevennes mountain range. Our villages are nestled at the foot of a hillside covered with evergreen oak trees, juniper bushes, thyme, "capitelles" (dry-stone cabins) and with a well-preserved "oppidum" (iron-age settlement) at its summit. >From the top, one can marvel at the splendid view over the plain of Vaunage (stretching between Caveirac and Calvisson), the Pic Saint Loup and the Mediterranean Sea on the horizon, and to the recognisable architecture of the Grande Motte (seaside town). On a clear day, one can even discern the peaks of Mont Loz?re, Mont Aigoual and Mont Ventoux. Our two little schools, served by a single school-bus-run, work closely together within an inter-town educational grouping ("Regroupement P?dagogique Intercommunal") and maintain a privileged relationship with all of the children. The Boissi?res school welcomes 61 pupils from kindergarten ("maternelle") to first grade ("Cours Pr?paratoire").in three classes and the Saint-Dionisy school receives daily 73 children from second grade ("Cours El?mentaire 1re Ann?e") up to fifth grade ("Cours Moyen 2e Ann?e") - also in three classes. The pupils are delighted to work together on a common theme between the two schools. They are charmed by this wonderful project of being able to communicate with Thomas Pesquet from space. They have been carrying out lots of learning work and are making discoveries about astronomy, the International Space Station and communication. We can be sure that many are already dreaming of becoming the next Thomas Pesquet! Participants will ask as many of the following questions as time allows: 1. Selma (4): Est-ce qu'il fait nuit dans l'espace? 2. Elia (8): Qu?est-ce qui a ?t? le plus difficile dans ta pr?paration? 3. Tom (5): Est-ce que la Terre est belle vue de l'espace? 4.

Ethan (5): Est-ce que c'est bien d'?tre dans l'espace? 8. Alexis (8): Un des plus beaux cadeaux de notre enfance serait que tu viennes nous voir : penses-tu pouvoir r?aliser notre r?ve? 9. Kylian (6): Qu'as-tu fait pendant le trajet jusqu'? la station spatiale? 10. Gabin (7): Est-ce difficile de vivre en apesanteur? 11. Gabriel (6): Est-ce qu'il pleut parfois? 12. El?a (10): Quelles ?motions ressens-tu lorsque tu travailles ? l?ext?rieur de l?ISS? 13. Tatiana (6): Avais-tu un sapin de No?l dans l'ISS? 14.

(6A7, 76 and a 77) Very feasible, but with gear that old I'd not want to rip out the old wiring etc. I'd look into a cosmetic plug in replacement. Then again, they are only $10. ;) Also, nowadays using a DDS as a signal generator is going to be more accurate, more stable. YMMWV > > I can do just about anything with bi-polar transistors...

It "should" be easy to specify a satellite QSO. There is no reason you couldn't simply pick a satellite name, and the logging program fills in all the other details required in the background. Some satellites with multiple modes might require a mode selection like AO-7. (In general the satellite name is good enough to know what the frequencies involved are. LotW only goes by band, not actual MHz value). As for uplink vs. downlink, it is no different than any other non-satellite contact. You log the frequency you transmit on. The REAL issue is that many people don't confirm via LotW. I sort of figure I owe it to the other guy, so I take the time to make sure my entries are correct. 73, Bob, WB4SON On Sat, Feb 25, 2017 at 6:31 PM, John Becker wrote: > I never was able to get it to work years ago. > Just gave up and moved on. > > John > > > _______________________________________________ > Sent via AMSAT-BB at amsat.org.

Along with the rest of the Amateur Radio satellite community, I hope that EO- 88 will meet all of its objectives. I wish you and your group the best of luck in this and future endeavors to keep Amateur Radio in space. [ANS thanks William A. (Bill) Tynan, W3XO, OSCAR Number Administrator for the above information] --------------------------------------------------------------------- Two projects with AMSAT ties selected for NASA launches Two cubesat missions with ties to AMSAT have been selected as part of the eighth round of the NASA CubeSat Launch Initiative. These spacecraft are eligible for placement on a launch manifest after final negotiations, depending on the availability of a flight opportunity. TJREVERB is a CubeSat from Thomas Jefferson High School for Science and Technology, in Alexandria, Virginia. This satellite will include an AMSAT Fox mode U/v FM radio system, and will be capable of serving as an analog FM repeater. HuskySat-1 from the University of Washington in Seattle will carry a mode V/u linear transponder and 1200 baud BPSK beacon similar to RadFXsat-2. The satellite will demonstrate plasma propulsion and high gain telemetry in advance of a larger CubeSat lunar mission. The complete list of satellites selected may be found at on the NASA web page. https://www.nasa.gov/feature/nasa-announces-eighth-class-of-candidates-for- launch-of-cubesat-space-missions http://www.amsat.org/?p=5795 [ANS thanks Drew, KO4MA, AMSAT Vice-President for Operations for the above information] --------------------------------------------------------------------- ARISS Equipment on SpaceX Launch Included as part of the successful launch of the SpaceX Dragon vehicle to ISS is an ARISS Ericsson 2 meter VHF radio. This radio will replace the Ericsson radio that failed a few months ago. The VHF radio is used for school group contacts and amateur packet radio in the Columbus module. Once the Dragon vehicle is berthed to ISS, the Ericsson will be unstowed and, at some point, installed in Columbus, replacing the UHF radio that is now supporting APRS packet and some school contacts. The unmanned cargo ship packed with food and supplies for astronauts arrived safely at the International Space Station Thursday, 2/23/2017. The Dragon cargo ship was grabbed by the station's robotic arm at 5:44 am (1044 GMT). Our thanks to SpaceX on an outstanding and historic flight from Kennedy Space Center's Launch Pad 39A, where many Space Shuttle missions and nearly all the Apollo moon missions were launched. We also would like to thank our ARISS benefactors-NASA and CASIS, the Center for the Advancement of Science in Space. And, of course, our amateur radio long-time sponsors-our national amateur radio organizations around the world, including the American Radio Relay League (ARRL) in the US, and our international AMSAT organizations, including AMSAT-NA. ARISS is also making great progress on the development of the new interoperable radio system that we hope to use to replace our aging radio infrastructure in the Columbus module and the Service module. The hard (and expensive) part of this effort is just beginning, with testing and human certification on the horizon. We thank all that have donated to the cause thus far. We hope you continue to help ARISS move forward through your support, including your volunteer time and talent and, of course, financial contributions through the AMSAT web site donate button.

This demonstration provides the first of the launch opportunities under the new Light satellite, Low-cost Launch opportunity (LLLor L3) Initiative initiated at the ESA Council Meeting at Ministerial Level in December 2016 with the aim to provide low-cost and regular launch services for European Institutional light satellites through full exploitation of the Ariane 6 and Vega C launch systems? capabilities. This first proof-of-concept flight using the current Vega launch system will demonstrate and validate standard innovative services for light satellites. The SSMS dispenser with its modular design enables Vega to provide launch opportunities for light satellites with an overall mass ranging from 1 kg CubeSats up to 400 kg minisats with different alternative configurations and relevant combinations under a ?rideshare? concept. Potential customers, be they European public-sector organizations or other entities, are invited to respond to the joint ESA and European Commission Announcement of Opportunity, which can be downloaded together with its questionnaire, by 31 March. http://www.esa.int/Our_Activities/Launchers/Vega_flight_opportunity_for_ multiple_small_satellites (including links for the application process due by March 31) [ANS thanks the European Space Agency for the above information] --------------------------------------------------------------------- Satellite Changes in AMSAT Keplerian Element Distribution The following five satellites/object numbers have been deleted: SATELLITE NORAD CAT ID REASON BY70-1 41909 Deorbit 2-18-2017 OBJECT 41930 41930 Not Amateur Sat-ISS Launch EGG 41933 Not Amateur Sat-ISS Launch OBJECT 41934 41934 Not Amateur Sat-ISS Launch TuPOD 41936 41936 Batteries Dead-ISS Launch Thanks to Nico Janssen for his work in predicting BY70-1's deorbit.

The 2U CubeSat BY70-1 was built by students from the Beijing Bayi High School and carried into a 524 x 212 km orbit on a CZ-2D rocket launched from the Taiyuan Space Launch Center on December 28, 2016. On February 17, 2017, as the satellite was about to burn up on its re-entry into the Earth?s atmosphere, this end of mission statement was posted on the school?s website. Dear friends of BY70-1: Satellite BY70-1 has completed all designed missions. For the amateurs who completed 2-way QSO using the repeater onboard, received effective satellite telemetry, or obtained satellite camera photos, we would like to invite you sending connection data package (audio or video evidence), satellite telemetry data or photos received to Email: 6015 at bayims.cn. So that we can keep statistics records and deliver our appreciation toward you in public. We would be pleased to exchange QSL card for QSO users, and some souvenirs for the telemetry or camera photos users.

April 15, 2017 The Amateur Radio on the International Space Station (ARISS) Program is seeking formal and informal education institutions and organizations, individually or working together, to host an Amateur Radio contact with a crew member on board the ISS. ARISS anticipates that the contact would be held between January 1, 2018 and June 30, 2018. Crew scheduling and ISS orbits will determine the exact contact dates. To maximize these radio contact opportunities, ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed education plan. The deadline to submit a proposal is April 15, 2017. Proposal information and documents can be found at www.arrl.org/hosting-an-ariss-contact. The Opportunity Crew members aboard the International Space Station will participate in scheduled Amateur Radio contacts. These radio contacts are approximately 10 minutes in length and allow students to interact with the astronauts through a question-and-answer session. An ARISS contact is a voice-only communication opportunity via Amateur Radio between astronauts and cosmonauts aboard the space station and classrooms and communities. ARISS contacts afford education audiences the opportunity to learn firsthand from astronauts what it is like to live and work in space and to learn about space research conducted on the ISS. Students also will have an opportunity to learn about satellite communication, wireless technology, and radio science. Because of the nature of human spaceflight and the complexity of scheduling activities aboard the ISS, organizations must demonstrate flexibility to accommodate changes in dates and times of the radio contact. Amateur Radio organizations around the world, NASA, and space agencies in Russia, Canada, Japan and Europe sponsor this educational opportunity by providing the equipment and operational support to enable direct communication between crew on the ISS and students around the world via Amateur Radio. In the US, the program is managed by AMSAT (Radio Amateur Satellite Corporation) and ARRL (American Radio Relay League) in partnership with NASA and CASIS (Center for the Advancement of Science in Space). More Information Interested parties can find more information about the program at www.ariss.org and www.arrl.org/ARISS. For proposal information and more details such as expectations, proposal guidelines and proposal form, and dates and times of Information Sessions go to http://www.arrl.org/hosting-an-ariss-contact.

I've been using LOTW for eight monthsnow. I have about 425 QSOs, of which 297 have bee QSL'd through LOTW. Over half of those that have not been QSL'd (over sixty) are with LOTW users. Most are single QSOs, but a number are hams that I have QSO'd with multiple times. Perhaps it may not be important to log those QSOs that have occurred with the same ham multiple times. For a ham working towards the Barbee (W4AMI) Satellite Operator Achievement Award, every QSO is important. At what point does one become a nag after politely asking others to QSL past QSOs via LOTW? I dislike being a nag! I've also found that it is sometimes difficult to contact hams to request QSL via LOTW. LOTW does not provide a mechanism, so I've had to resort to searches via qrz.com in the hope of finding a valid email address. It is probably asking too much for LOTW to provided a mechanism to politely 'ping' users to log their QSOs. 73, Mac / AE5PH On 02/25/2017 06:51 PM, Bob wrote: > The REAL issue is that many people don't confirm via LotW.

Not meaning to hijack the thread, but I'm a bit surprised about that. I would have thought that the need for verification would be a given. I guess it would have been impractical in the days when verification was only via QSL cards. With systems like LOTW and qrz.com, perhaps not as impractical.

My SatPC32 registered copy works fine with Fodtrack on XP but gives an error when SatPC32 accesses the fodtrack.exe file using Win10. The error is "Exception EOLISysError in Module ServerFODTrack.exe bei 0005E909. Class not registered." The new motherboard I am using does not have a parallel port on board so I have been trying both PCI and a PCIe cards without success. I also have changed the required bits in SatPC32 config ParPort.SQF file to suit but no luck. Tried calling other rotator interfaces and they seem to run ok given I don't have that hardware. Also tried running SatPC32 in compatibility modes but no luck there either. It does not drive the fodtrack box but otherwise runs ok. I would rather ask before playing around with the PC's REGEDIT stuff which could be terminal.

SatPC32 control's both the uplink and downlink frequencies, and it seems to track perfectly fine with VFO changes on the downlink, and set's the uplink to the appropriate match, but when I use my RIT knob on the TS-2000 to change the uplink frequency offset, SatPC32 overwrites it. What do you guys find is the quickest and easiest method for finding your uplink? Thank you! Mike, AE0MT.

I start by first setting my radio to the nominal frequency and then adding whatever offset to the downlink may exist. If there's already traffic there, I go elsewhere in the band so that I don't interfere with the QSO. I then make a test transmission to fine-tune the downlink with my software. I identify myself and why I'm on the air so that anyone listening will know that I'm not ready for a contact. Since I have to set up my station outside and I'm holding my Arrow yagi, it's easier for me to do that by voice rather than transmitting CW. I adjust the downlink because I figure it's more important that other stations hear my signal and avoid it while I'm tuning. Usually, though, it takes me about a minute to find my signal. After it's all set up, I can start calling CQ. I use Gpredict for controlling my radio. It allows me to adjust both the uplink and downlink, making it easy to fine-tune my signal or QSY to a different frequency. 73s Bernhard VA6BMJ @ DO33FL From bruninga at usna.edu Sun Feb 26 15:20:12 2017 From: bruninga at usna.edu (Robert Bruninga) Date: Sun, 26 Feb 2017 10:20:12 -0500 Subject: [amsat-bb] Solid State conversion (tube equivalents)?

The three tubes would need 6.3v at 1 amp. I could get the plate voltage from a simple voltage doubler from 60 Hz.. Since 5v 1A switching wall-warts are throwaways, they would be a great filament supply except that 5v on the filament vs 6.3 is like a 37% reduction in filament power. Humm... Ill have to look for a 6v DC/DC supply... Our use two 5v's in series and use a series regulator down from that.

I had been thinking about ways to use the earths magnetic field to raise perigee by storing energy in capacitors and pulsing something along the lines of a magnetorquer with a high current pulse at the right time and vector. The problem, I think, is that I would need to generate the thrust at apogee where the earths magnetic field is weakest. - Howie AB2S ________________________________ From: Phil Karn Sent: Saturday, February 25, 2017 12:41 AM To: Howie DeFelice; amsat-bb at amsat.org Subject: Re: [amsat-bb] BY70-1 On 2/24/17 07:55, Howie DeFelice wrote: > Very interesting Phil, it seems to make sense that this calculation > could be used in reverse to calculate the energy needed raise the > perigee height of a GTO orbit.

Otherwise, things are much more complicated with a chemical or electrical rocket because you have to carry your reaction mass with you and then put energy into it to blow it out the nozzle at high speed. There's a fundamental tradeoff in rocketry between rocket power and propellant mass flow rate. You can produce a given amount of thrust with high power and a low propellant mass flow rate, or with low power and a high propellant mass flow rate. E.g., to produce a thrust of 1 N with a mass flow rate of 1 kg/s, you have to eject it at 1 N / 1 kg/s = 1 meter/sec. Ignoring relativity, the kinetic energy in 1 second of exhaust (1 kg) will therefore be 1/2 mv^2 = 1/2 * 1 kg * (1 m/s)^2 = 0.5 joules and since you need 0.5 joules every second, the required power will be 0.5 watts (assuming 100% efficiency). If you double the exhaust velocity to 2 m/s, you can drop the mass flow rate to only 1/2 kg/s and still get 1 N of thrust (1/2 kg/s * 2 m/s = 1 N). But you'll now need a power of 0.5 * 0.5 kg/s * (2 m/s)^2 = 1 watt i.e., twice as much power for that same 1 newton of thrust. So, which do you have more of, propellant mass or energy? In a chemical rocket the energy is stored in the unburned propellant, so the energy per unit mass is set by the propellant chemistry. That's why every propellant combination has a theoretical specific impulse, e.g. 455 seconds for hydrogen/oxygen in vacuum. Specific impulse is just effective exhaust velocity divided by g = 9.8 m/s^2, so the theoretical exhaust velocity for hydrogen/oxygen is 4,462 m/s. But in an electric rocket the energy source is external to the propellant mass, so the energy/mass ratio can vary; you decide how fast to eject it. If mass is cheaper than energy, then you want a low exhaust velocity. If energy is cheaper than mass, then you want a high exhaust velocity. Since the rocket is free to move, the kinetic energy it produces will be split between the payload/rocket itself (which you want) and the exhaust (which is effectively wasted). The only way to get 100% of the energy into the payload/rocket and none into the exhaust is to set the exhaust velocity equal to the current velocity of the rocket so that the exhaust comes out stationary. Of course, velocity is relative so you measure it relative to the reference frame in which the rocket is initially stationary. So to minimize energy consumption you want to increase the exhaust velocity as the rocket accelerates. That's the exact idea behind the VASIMR (Variable Specific Impulse Magnetoplasma Rocket). The recent "EM drive" hype notwithstanding, I know of only one way to produce thrust in vacuum without some kind of propellant: the photon rocket. Even a flashlight will work, but let's do the numbers. The momentum of a photon is equal to its energy divided by the speed of light, so to get 1 newton of thrust from a 100% efficient photon rocket requires a power input of 1 N * c = 300 megawatts! That kind of power in space requires either a very large solar array or a very big nuclear reactor (which still needs a very large radiator to reject waste heat). But there's a simpler way to power a photon rocket with the sun. Instead of turning solar photons into electricity and back into photons, why not use solar photons directly? Voila -- that's what a solar sail does. The thrust produced by a solar sail per unit area is equal to the incident solar power per unit area divided by the speed of light. At 1 AU that's about 1361 W/m^2, so the thrust will be 1361 W/m^2 / c = 4.54 micro newton/m^2. That's actually units of pressure, so solar radiation pressure at 1 AU is 4.54 micropascal on a sail normal to the sun that simply absorbs solar photons. If you reflect them back, you'll get twice as much, 9.08 micropascal. Doesn't seem like much, but you'll get it continuously, no local power source or propellant mass needed. The one big problem with solar sails is that you can't use them in low orbits because they'll generate far more drag than thrust. 73, Phil From rjlawn at gmail.com Tue Feb 28 01:19:24 2017 From: rjlawn at gmail.com (Richard Lawn) Date: Tue, 28 Feb 2017 01:19:24 +0000 Subject: [amsat-bb] ARISS packet Message-ID: I read JoAnne's article in the recent AMSAT journal issue with great interest as it was somethingnive never done.

Thank you everyone for the help this past weekend getting me back on the birds. One step at a time. Eggbeater's are in process, and with any luck, that will do the trick for now. I come to you guys with a little bit of an unexplained situation I am having with my TS-2000. For whatever reason, it seems to be showing full scale RF input, but it doesn't seem to hear anything. The current antenna is a Comet GP-15 Tri-band vertical on my roof. It's common coax is connected to the common port of a Comet CFX-514 Tri-plexer. I had this triplexer on a VNA at work for giggles, and I found it to have about 50dB of isolation between the port's. Does this seem like I am overloading the front end of the 2m side with the 70cm transmit through the triplexer? https://youtu.be/eV_HGuw60_4 Thank you for your help and suggestions.

There are some changes in UISS settings to work with Soundmodem (Figure 10 in the article) which you likely have made. I start Soundmodem first followed by starting UISS. When UISS starts it shows a message that it connected with Soundmodem: Connected to Server 127.0.0.1 Port1 with SoundCard Ch: A; On the UISS main screen I set these pulldowns (you can manually type in the values if they aren't in the pulldown menu): To as CQ Via as ARISS TX Text/Data as =4211.29N/08827.08W-Greetings (my lat/long, the "-" is the code for the house symbol on the map, and Greetings is whichever text you want to use for CQing. When I click the Text/Data F5 button it transmits. On the Soundmodem settings I've selected AFSK AX.25 1200bd and I left that little window set at 1700 which seems to be a default. One note about the soundcard packet applications is they will only display packets that are 100% correct with no checksum errors. I miss the feature on hardware packet where you could PASSALL to the screen including the incomplete packets. Some packets sound "good" but if it contains a checksum error the software won't display the message. I don't know if the Flex 5000 needs any additional interface settings. I've observed what Alan mentioned that Soundmodem on receive is pretty tolerant of levels. I'm seeing different sound levels on receive here between different computers. I know my FT-857D is sensitive to transmit sound levels and I need to use the Windows audio mixer slider to keep the FM deviation within limits. On another computer running an SDRPlay for receive I've observed that VBcable always seems to run with higher levels but Soundmodem decodes OK. > ... clues how to set up UISS for terrestrial APRS packet on > 144.390 to enable me to test this setup by getting some feedback > that shows things are working? When I listen on 144.390 for testing all I see is the raw APRS data. I don't transmit on 144.390 since I'm not active on APRS (cool maps though). The raw APRS packets look like: 1:Fm W9RCG-2 To APU25N Via K9ESV-10*,WIDE2* [09:43:58R] [+++] =4307.10N/08807.20W#APRS&DIGI @ Menomonee Falls, WI {UIV32N} I find it useful to see some test signals on 144.390. In the mishmash of callsigns and routes you can tell who transmitted the packet by the asterisk. The only path information you need for ISS packet is the UNPROTO set to CQ VIA ARISS. I found that the settings to decode terrestrial packet transfer directly to receiving packets from the ISS and PSAT even though the content details differ between terrestrial and space. The map on http://www.ariss.net/ only shows that stations that were received by a satgate station. Sometimes half of my packets aren't gated via satgate to the internet even though I received my own (and others) packets directly at my station. This web page will still show you if you were satgat'ed without you sending APRS information. You'll see your transmitted text without position information. If you transmitted position information that would be displayed on the map portion of the web page. (That map is zoomable so you can get close-ups on your area.) I guess it goes without saying, but I'll say it anyways, tracking the Doppler shift on 437.550 is important on both the transmit and receive legs. Packet on 145.825 will be easier once they get the chance to install the new Ericsson radio. -- 73 de JoAnne K9JKM k9jkm at amsat.org From py4zbz at yahoo.com Tue Feb 28 19:02:21 2017 From: py4zbz at yahoo.com (Roland Zurmely) Date: Tue, 28 Feb 2017 19:02:21 +0000 (UTC) Subject: [amsat-bb] Nayif-1 spin graph References: <1089965833.650438.1488308541210.ref@mail.yahoo.com> Message-ID: <1089965833.650438.1488308541210@mail.yahoo.com> An interesting assembly of graphs Z + and Z- shows the rotation of the satellite.Please see here: 73 de Roland PY4ZBZ From n4qwf1 at gmail.com Tue Feb 28 20:54:25 2017 From: n4qwf1 at gmail.com (n4qwf .)

The transmitter is on and transmitting and the signal strength is going up and down due to 'tumbling', ploarity shifting, etc. The reason you hear static is that it's not like SO-50; instead of squelching when there is no signal, AO-85 simply rebroadcasts what it hears... which at the moment is 'nothing', SO it is passing the white noise from it's UHF receiver straight to the 2m transmitter. Eventually you heard a voice there at the end, so yes, you ARE hearing it. If I read the TS-2000 manual correctly, your problem is that you have the PL tone set on the receive band... not the transmit band. The 'T' should be above the sub band display in other words. So since you are not transmitting the proper PL tone of 67.0 Hz, you are not able to hear yourself come through the transponder. See about fixing that and give it another try. And from experience, I'll suggest to double check that even after you get the 'T' on the correct band, verify that it's 67.0 Hz.? =^) 73, Kevin N4UFO From wa4sca at gmail.com Tue Feb 28 23:22:44 2017 From: wa4sca at gmail.com (Alan) Date: Tue, 28 Feb 2017 17:22:44 -0600 Subject: [amsat-bb] ARISS Packet In-Reply-To: References: Message-ID: <000001d29219$910c8440$b3258cc0$@gmail.com> Rick, In your original post, you said " I have no decoding packets whatsoever either from ARISS or terrestrial on 144.390." Since RX is in fact working, the most likely transmission problem with the Flex is that compared with traditional rigs, there is considerable latency, or delay, between the audio input and transmission. The result is that the transmitter cuts off before the full packet is sent. Fortunately there is a parameter, TXtail, which will keep the transmitter keyed for a period after the audio is sent. Somewhere in Soundmodem, probably the Modem tab, IIRC. Try setting it for 500 ms or so, and see if that helps. It solved my problem. After you get it working, you can cut that back a bit, if desired. How much is a complicated function of sampling rates, buffer sizes, etc. Another issue is deviation. Too much is much worse than too little. I find that setting VAC at -14 gives me 3 KHz deviation. 73s, Alan WA4SCA <-----Original Message----- In case anyone is still looking, our final passes will be tonight, all times EST.
