Dear all,
We have a functional Ground station setup at QTH location MK68WM. We have a
2 Unit array of circularly polarized Yagi antenna mounted on antenna rotor
system for tracking satellites operating in UHF band.
Instrumentation available with us is Signal generators, Signal Analyzers,
Vector Net
Amateurs are invited to submit technical papers for presentation at the 33rd
Annual ARRL and TAPR Digital Communications Conference to be held September 5-7
in Austin, Texas. These papers will also be published in the Conference
Proceedings (you do not need to attend the conference to have your

I have listened several times and never heard the CW beacon, so that's neat.
The channel 6D value shows the telemetry to be nothing more than
gibberish, unfortunately, as that number should be 50 +/- 1.

One way to measure the g/t is to use sun noise. You point your antenna
toward the sun and cold sky and measure the delta noise. Use that attached
ss to calculate the g/t . I have a similar system and let compare notes.
Also take a look at the SETTI League doc for back grown

I have experienced a similar problem in satpc32, although the error message is
not exactly the same. I see this only on a Win 8.1 PC. One thing I have done
with some success is to IMMEDIATELY update Keps as soon as satpc32 finishes
booting. I am also interested in a permanent fix for this.
Red,
I tried an experiment today on the 1630Z pass . My normal

Dear radio amateurs,
A courtesy notice that LituanicaSAT-1 transponder will be operative until
June 5, 0100z. At about this time period a scheduled reset should occur and
both CW FM beacon on 437.275 MHz and 9k6 baud telemetry on 437.545 MHz
should be heard. We encourage you to send reports to fin
Dear Laurynas
This afternoon we had two good passes over Brazil and we make contact with
PY4ZBZ, PU2NGB .
Here are an sample of signals receive on the last 3 days .
Thank you for this nice sat .

Bob,
I can tell you from years of experience with writing tracking programs for
Windows and iOS that one of the biggest problems is decay. Strange things
happen to math routines when the altitude of the satellite drops below the
surface of the earth. One solution is filtering out these decayed sat
I was listening to AO-7 in Mode B as it rose at 2153Z.
At 2158Z, AO-7 suddenly switched from Mode B to Mode A.
At the time of the switch, there were two stations using excessive power (badly FMing) on the bird. Not sure if that was a
coincidence or not.
Called CQ on Mode A in both CW and SSB

I had to try the last pass before that moment in JO22nc (and the first pass
in a while at a usable time for me). Heard at least two QSOs but
I find it odd that they did not reply to you in Mode A. Given that the
warnings about excessive power can lead to random mode switching on
AO-7 stretch back 37 years, one can only conclude that they wanted the
satellite to be in Mode A.
