> 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
Should be a less than one second burst every 30 seconds on 145.870.
Should be near the pass times of CAPE...
