[amsat-bb] LVB

Sat Jul 11 14:58:22 PDT 2009

I built my LVB up from the bare board which I ordered from G6LVB direct in the early days. It was a fun home brew project. Mine is bare bones. It has no display and no buttons. It just sits inside a Radio Shack box and does its thing day after day. If you look at my unit, the PCB just has enough of the components on it to do the job which it does well.

I would highly recommend the LVB, it works well and is supported well.

The $200 is a great deal. I helped sell every one we had on hand at the
AMSAT booth in Dayton. Another perspective, about 2 years ago I replaced my
ISA bussed motherboard for a new one. The only ISA bussed mobo I could
find(that was under $500) cost $190. Other then the two ISA slots, it had
the comparable performance of a $35 mobo! My next computer upgrade for my
sat control system will use an LVB to control rotors. The Kansas City
tracker ISA card will be heading to the Smithsonian Institution....

Hi Myles,

Simply stated---this is a very functional and easy to use track box,
with exceptional attention to construction detail when purchased
already assembled by AMSAT (thanks, Mike Young!).   It's a very fair
price at US$200.  (Price out the parts to build one up...it's a deal).
It's essentially plug in, calibrate, then play!

73,

Mark N8MH

>> John -- I think Greg means the 8-pin DIN, not the mini-DIN ....
No.  The PSK-1 RS-232 port to the Computer is J10, which is a mini-8 DIN on rear panel.
I am looking at the back panel of my PSK-1 here in workbench!

The PSK-1 also has 8-pin DIN (J2) for the TNC Modem Connection (via 20-pin TAPR disconnect header on Tiny-2 or TAPR TNC-2);
and three 5-pin DIN connections: TNC Radio Connection (J4); VHF Radio (J1); UHF Radio (J3) --- 
the separate VHF and UHF radio connections were useful for the Icom VHF/UHF radios (271/471; 275/475) of that era.

The PSK-1 and PSK-1T modems do have different rear panel connector types!
LOOK at the REAR PANEL (eBay auction # 320392587069 has a rear panel photo)
On the PSK-1T, there is an 8-pin Mini-DIN marked CONTROL (RS-232), I assume that Gywn kept the pin out the same as the PSK-1
and would connect this to a PC serial port (RS-232) that is running a terminal emulation or control program.
To the left is a Male DB-9 marked PACKET (RS-232) ... A manual for the PSK-1T will confirm its usage/connections.

As I remember, and W3IO probably has a better memory, PacComm introduced the PSK-1 for the PacSats launched at that time.  
Later, Gywn reintroduced the PSK-1T with some updates and suggested modifications.  
I first saw a PSK-1T at the 1995 AMSAT meeting in Orlando (1995) --- shown in preparation for AO-40.

Mark, I was watching that eBay auction (# 320392587069), but did not bid on these items -- I already have one!
There were two PacComm PSK-1 and DFM TNC combinations for sale on QRZ a couple of weeks ago at $35 per set or $50 for both (great deal)!
Yes, the DFM permits usage at 9600 AFSK (which one of the satellites did support).

Hi Greg,

"//
To get me going can some one  please send the pin out for the radio 8
pin DIN for the DFM TNC.

Thanks de John K0CQW
"

Um..back to the question John asked--it was about the 8pin DIN on the
DFM, not the PSK unit.  The DFN TNC doesn't appear to have a mini-DIN,
so, that's why  I didn't think the mini-DIN answer was what he was
looking for :)

http://cgi.ebay.com/ws/eBayISAPI.dll?VISuperSize&item=320392587069

Excellent information, history and details, though, Greg!  Thanks!
In the shack I have a couple each of the PSK-1 and PSK-1T units, and
manuals.  The PSK-1T with the built in TNC is really slick (the "T"
designates the built in TNC, no disconnect header hookup needed!)

Hopefully the chatter will help John get his stuff going--but I think
he STILL needs the 8pin DIN info for the DFN....my hunch is that it's
the Paccomm "standard" pinout for hooking up the tx audio/rx
audio/PTT/GRND, but I can't confirm.

If you participated in AMSAT Field Day and would like your efforts to 
count towards AMSAT Field Day, you have until Monday, July 13, 2009 at 
11:59PM CDT to submit your entries. They can be emailed to me at 
kk5do at arrl.net or kk5do at amsat.org
You can also send them in the mail but give plenty of time for them to 
arrive or you will be out of luck. I will send you a confirmation email 
when I receive your entry (might take a day depending on my work 
schedule). Photos and neat descriptions of your field day antics and 
events are welcome.

Cost is very reasonable-AMSAT gets the profits-after purchase support is excellent- easy to setup and use
