Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

Has anyone located a driver for the LVB Tracker internal USB to serial
port adapter on Windows 7 x64?
If not, has anyone reverted to the serial port connection on LVB Tracker
and used an external USB to serial port adapter successfully with
SatPC32 on Windows 7 x64?
I have an Edgeport multiple USB to serial port that has drivers for
Windows 7 x64 that I will use if I have to. I would prefer using the LVB
Tracker with its USB to serial adapter if someone has another solution.
Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to
get some telemetry packets. The satellite would remain on for less
than one minute after being commanded on. A quick test of the "bent
pipe" voice mode repeater was successful. . The "hardware watchdog
timer problem" is still evident; as expected, spacecraft temperatures
are insufficient to keep the transmitter ON (needs to be above 15 deg
Orbit projections suggest that satellite illumination conditions will
not result in increased temperatures for nearly 10 years. Command
stations do periodically turn AO-16 "ON" to check on its condition and
see if the hardware timer problem has "automagically" fixed itself
(which in not anticipated, but who knows...).

Here is another teaser :) Several months ago I commanded the AO-16
S-band transmitter ON; it too remains functional (albeit weak), and
was received by me, Drew KO4MA, and Alan WA4SCA.

The ideal AMSAT FM transponder for a cubesat is the PSK-31 transponder
being developed for the Naval Academy PSAT mission.
With an FM downlink, anyone can receive it with an HT and a laptop with
PSK-31 software. And anyone with a 10m PSK-31 uplink can transmit to it.
The reason it is ideal is that it is a multi-user transponder supporting
up to 30 users at the same time. Everyone can transmit horizon-to-horizon
and see everyone else. A big QSO party in the sky:
And since it is FM, Everyone tuned into the downlink SEES THE SAME
WATERFALL and sees EXACTLY where they are in the downlink. A small uplink
doppler adjustment can keep each station locked to his chosen channel in
Everyone can talk to everyone if they want, or go one-on-one too.
The SSB uplink and UHF downlink transponder fits on a smaller than 3"x3"
circuit board being developed by Mirek Kasal at Brno University.
If we could just get more Cubeats to fly these things, we would have all
the joys of multi-user transponders, and yet they fit well in any cubesat.
The ONLY problem is the HF wire antenna. Ours is going to be a 4 or 6'
whip of Nitinol Wire.
In addition to thes PSK-31 transponder, PSAT also supports the usual APRS
AX.25 transponder on 145.825 too. Launch is planned for Summer 2013.
I will have an AMSAT table at the new Tucson Hamfest and Fly-In,
hosted by the Oro Valley Amateur Radio Club. The hamfest will be
next Saturday, 6 October 2012, between 0700 and 1300 local time
(1400-2000 UTC). This hamfest will be at a new location northwest
of Tucson, at the Marana Regional Airport along Avra Valley Road
west of I-10 exit 242. More information is available at:
I will have on-air demonstrations throughout the hamfest, starting
with an SO-50 pass just before the official 1400 UTC start of the event.
I will work passes on that satellite, as well as VO-52 and FO-29, until
an AO-27 pass just before the 2000 UTC end of the hamfest. For the SSB
satellites, I will try to start out around 10 kHz +/- above the center
of the transponder. If you hear WD9EWK on those passes, please call and
be a part of the demonstrations. The hamfest site is in grid DM42jj.
If you work WD9EWK next Saturday and would like to receive a QSL card,
please e-mail me with the QSO details. QSOs will also be uploaded to
Logbook of the World after the hamfest.
It's apparently setup to use hardware modems. This shack loves hardware TNCs :)
You might be able to get AWGPE working if you can send KISS data out to a virtual com port...check out http://www.soundcardpacket.org/
"In addition, Tim Pearson KB9VQF has written a <http://www.pearsoncomputing.net/freeware.php>AGWPE Serial Loopback utility that creates virtual serial ports that will let you link AGWPE to any packet program that can link to a KISS-enabled TNC (AGWPE's sound card mode simulates a KISS TNC). "

Anyone who would like to try to establish a new distance record on AO-7 mode B, get hold of me. I believe the current record is 7766km. The potential distance is 7907km. I have worked out to 7692km thankyou OH5LK. New satellite tower/antennas complete. I am located near Seattle Wa...CN87wk and enjoy trying to stretch the footprint. The difficult we do immediately the impossible takes a little longer.

Yes, that'll work. You'll make your head hurt getting it all set up tho :)
Quick outline of approach:
1) get AWGPE installed and working.
2) install a virtual serial port pair using something like com0com; use baud emulation.
3) install AGWPE KISS-Mode Loopback interface. Configure to use one of the virtual ports; use 9600 baud.
4) Now launch/configure F-1 Telemetry decoder. Pick "the other" virtual com port, use 9600 baud, and then start it.
Use local APRS packet traffic to test...you should be printing it (raw data....
It takes a bit of monkey-ing around, but it works!

*You should connect this program with your transceiver first.
Not sure what they are looking for here. I would like to use AGW Packet Engine
as my packet TNC. Anyone offer any guidance in how to configure APWPE to the
F1 decoder program ? I also have MixW if that would work...
Here is a news item that would be too late if we waited for the next ANS
I'm posting this as a favor for Tom W5KUB since many hams enjoy his live
amateur radio webcasts. AMSAT is not sponsoring any part of this event nor
endorses any of the products or commercial content.
Lots of hams have a good time during Tom's shows so tune in if you can. You
might win one of his on-line prize drawings too. He randomly picks a
participant in the webchat.
When live webcasts are not going on he loops recordings of his previous
shows. His amateur radio webchat is available from his web page also.
