[amsat-bb] Re: Pehuensat-1 heard in europe

[Mike Rupprecht]

Tony,

AOS 2015 UTC for my QTH JN49lr
LOS 2028 UTC

BUT – no signals after 2024UTC (the transmission stopped). If you
analyze the telemetry, especially the values Battery1 and Battery 2 you
can see the decrease. Battery 1 Voltage goes back to 12.2 volts, Battery
2 Voltage to 12.1 volts.

I analyzed my mp3 file and could decode more frames. Here are the frames
with correct timestamp:

I wonder, that the nominal AFSK frequencies are not 1200Hz and 2400Hz
but 1330Hz and 2530Hz. I think, a standard TNC will not decode this
signal.

Mike,

Thanks for passing that along. I've been trying to copy the Pehuensat
during 
the nighttime passes, but no luck.

Going to try again tonight around 0120Z during orbit 246. Did you hear
the 
voice anoucements?

Hi all,

just heard strong signals from Pehuensat-1 (2015 UTC).
Here are the first frames (will analyze the file and try to decode more
frames.)

Time is not the original time ( X- abt 15 minutes)
