Andy -
You are missing key pieces ... Like TTL to RS232 conversion.
McGrawHill has publications on RS232 prog in "C" lang. I have these in home library.
Start there.

I will be putting W1AW on AO27 for a demonstration (HT and ARROW) during the
teachers institute on July 28 (Tuesday) probably during the 1216(L) pass.
Your assistance with the demonstration would be appreciated. If you would
like a QSL of the contact, please send yours to WA8SME, and I'll take care
of it. No SASEs required.

It's great to see the renewed interest in activating
"rare" grids on the birds. If you don't have a particular grid
worked and confirmed, it is a "rare" grid. It is important
for all of us to recognize those who are operating "portable"
in a grid away from their home. They are only there for a
short period of time so giving them the frequency is the thing
to do. If you hear a callsign that you have not worked before,
call that person rather than someone you just talked with on
the last pass. We need to encourage the new people as they are
the future of the amateur space program. Use the portable
designation if you are operating away from home so others will
know that this might be a new grid.
We have enjoyed a long stretch of AO51 being in the V/U mode on
435.300. After the end of the month, the bird will be in sunlight
continuously and that will allow higher power and other modes to be
used. If AO51 is in a non-V/U voice mode, as it was for a 2 week period
not long ago, grid dxpeditions are not going to be worthwhile. If
you plan a vacation ahead of time, you might find later that the bird
will not be in a v/u voice mode during your trip.
The Operations Team sets the schedule and they do it based upon
requests from the membership for alternate modes. Personally I think
that there should always be a 435.300/145.92 mode available. Everyone
who is interested in chasing grids or activating grids away from their home
should email KO4MA and request that V/U voice remain on. You cannot
plan anything if you don't know if AO51 will be in V/U voice during your
trip. The schedule is based upon input from the membership and if we
don't make our requests, those that want the bird in other modes (both
transponders) will most likely be served. The second transponder is fine
for other modes but there are probably some modes that cannot be activated
if V/U voice is to remain on. Maybe Drew can clarify this for us.
There are some that would say that there are other satellites that can
be used for FM voice. Very true, however, if you are out there trying
to activate grids, not having AO51 available is a handicap. You spend a
lot of money to do it and then have 1/3 of your potential air time, on the
best FM satellite up there, not available to you. It makes no sense.
I'm on L band now and will have S band RX running soon. I enjoy setting
up for different modes. But after you work a few stations in those modes,
and fine tune your equipment, there's not much left. Chasing grids never
ends. There's always one more to work.
If you are interested in working or activating new grids, please email KO4MA
and request that AO51 always have one V/U voice transponder available. There
is no guarantee that this will always work, but if there are no emails, it is
likely that there will be more periods of non V/U voice on AO51.

John,
I certainly understand where you are coming from, although I disagree with
some of your positions. AO-51 is currently our only satellite with multiple
modes (other than ISS), our only S band satellite, our only BBS, our only L
band satellite, etc. Unfortunately our power budget doesn't allow us to run
every mode we want to at the same time. This problem will only get worse as
the batteries age. We are already at the point where after this extended
period of mostly full illumination, we will most likely only be able to run
one transmitter at any time, and possibly not the S band in eclipse
at -all-.
The good news is that the full illumination lasts for quite a while, and
during this period we can support two UHF transmitters at a high power
level, or one UHF at modest power and the S band transmitter. If we run
separate S and UHF, the UHF downlink will have to be on 435.150, as the
435.300 and S transmitters share an audio path.
So...that being said, do not expect us to completely forego L and S just for
more grid swapping, as fun as it is (I'm at 550 confirmed). Send your
requests in early for whatever mode you'd like, and we will try to honor
them. Meanwhile, get your S band downconverters ready for portable ops, your
817s and 706s working with SatPC32 on a laptop, and be ready to occasionally
run your grid trips on ALL the satellites. It's a real shame to hear so many
ops on V/U FM, and so few on V/U and U/V SSB/CW.
Since I try to walk the walk, look for me on the SSB -and- FM birds as G/
and OZ/KO4MA over the next 2.5 weeks. I hope to stretch the footprint to
North America on FO-29 and AO-7 with my little 817 and Arrow setup.
Mode requests should go to ao51-modes at amsat.org, not to me direct.

Please excuse me for posting this, but in this tight job market I felt
might be of interest to some AMSAT or ARRL folks.
I know of job opportunities for someone in the San Diego area that has
either satellite or submarine communications experience in the DOD. If
you have either or both, please contact me OFF LINE and feel free to
send your resume. Thanks

Hi AMSATs,
Last weeks I have been working on a testboard for the very small linear transponder system that I have designed.
I plan to be at the JARL Ham Fair in Tokyo, Japan on 22nd and 23rd August, where I will present my thiny linear transponder to the ham people.
I will be in Japan from 15th August till 27th of August.
When some University Cubesat group in Japan is interrested in my transponder design I can give demonstration and presentation.
Only serious parties please.
Please see some older movies about my transponder design on youtube:

73, and maybe see you on Ham Fair Tokyo,

Hi William...
It is good to see one person accomplish so much for us satellite users! You
already have a successful transceiver in orbit and a launch behind you!
Keep up the good work!

ok so what about this question,
say you are going to go on vacation or moble /expadition,
and you know that they?are changeing?AO-51 to say L/S mode for next week,
?
would a HT that has L band FM transmit (DJ-G7T) 1 watt
be ok or would you a 10watt amp with the proper antenna,?
to kick the bird :-)
i have the S band covered almost.?

HI,
I'm looking for any simple source code in C-language for FX-614 (ax.25
decoder) for undestanding simple ax.25 protocol. I found only few
asm code for PIC16, but c-lanugage is easily to adopt to other microcontrollers.
I tried to connect FX614 IC like in HITSAT
http://www.hit.ac.jp/~satori/hitsat/img/decord.bmp and read at RX PC
port with rs232 terminal programme,
but I didn't receive any useful frame with b011111110 start (like
describet in ). After this I found that all modem using pin CTS on
RS232 port, I don't know how to handle this with
PC to read directy with rs232 RXD port like HEX or binary values to
see raw values of packet frames?
It is possible to read values from FX614 (through max232 ) with PC to
see raw format?
So I'm looking for any simple source code in C to find how to decode
signal from fx614 to microcontrollers port and then to PC
Thanks for your help
all the best Andy

Hey everyone,
K5E - The 40th Anniversary Apollo 11 Satellite Special Event - has concluded. My thanks to everyone for making this a fun and memorable special even on the satellites.
Here's a brief summary:
The K5E log contains 338 contacts representing 182 different operators.
Contacts took place on all of the FM satellites (AO-27, AO-51 and SO-50), all of the CW/SSB satellites (AO-7, FO-29 and VO-52; both CW and SSB contacts are in the log), and via the International Space Station. The ISS contact was a two-way direct-packet contact between K5E and KB1GVR, in Maine.
I will post a more detailed summary in the near future.
Thanks to AA5PK, K8YSE and WA4NVM who assisted by operating portions of the special event as (their calls)/K5E. Their assistance proved valuable in expanding coverage throughout North, Central and northern South America.
QSL Cards are in transit from the printer! Thanks again to Glade Schroeter, WA3MVQ, and GGGraphicsstore.com for donating the cards.
My goal is to have all on-hand QSL requests filled and back in the mail by no later than July 31. If you worked K5E and have not requested a QSL card, please do so with an SASE. Direct all QSL requests to N3TL at the address on QRZ,com/N3TL.
Thanks again to all, and 73,
Tim - N3TL
