> Nothing heard from DragonSat on 145.870. (9600 baud AX.25)
A crude test of a Dragonsat model with the antenna un-released was still
radiating on the order of 26 to 36 dB down.
>From now on, instead of FM, we are going to listen with an SSB receiver
and see if we hear the 30 second chirps. Listening on SSB should improve
our listening sensitivity 20 dB or so, plus an added 10 dB on direct
overhead passes might make it detectible if the only problem is antenna
deployment.
Should be a less than one second burst every 30 seconds on 145.870.
Should be near the pass times of CAPE...

Has anyone heard TRITON-1? I listened for two passes today and haven't
heard any downlink signals.

The $50sat team is asking for help form our friends in the southern
hemisphere in capturing telemetry form $50sat. We are trying to determine
the charging characteristics of the power system. The three team members all
live above 40 degrees north and the satellite does not warm up enough during
N-S passes to allow charging to begin. None of us are usually around during
S-N passes. Any form of report is welcome: decode of the fast morse
(120WPM), RTTY demod, audio recording or I/Q capture from a Funcube or RTL
dongle would be greatly appreciated.
A link to a detailed description of the communications package can be found
on the $50sat website, http://www.50dollarsat.info . The last distribution
of keps from AMSAT contain good elements for $50sat.
$50sat is one of the smallest amateur radio satellites ever launched at
2"x2"x3" and weighs only 210 grams. TX power is just 100mW.
Thanks,
Howie AB2S
