Feb 11, 2018 · Right now, the only regularly working satellite for packet or APRS would be FalconSat-3.Unlike with the ISS or NO-84, you need a radio capable of 9600bps packet, and where the TNC can function on more than a simplex frequency (FalconSat-3 uses a 2m uplink and 70cm downlink). APRS PROTOCOL: APRS has long been recognized as a channel effecient protocol requiring only a single one second packet per station to report position and status. This is a tremendous advantage to the amateur satellite system, because it allows a maximum number of users (probably 200 or more) compared to the usual dozen or so with these PACSATS.

All APRS satellites and the ISS use any of the three generic paths of ARISS or APRSAT or WIDE. Since all of these satellites supports the same generic paths (when properly configured), this means you can operate either ISS or PCsat or PCSAT2 without reconfiguring your TNC! Just set your UNPROTO path to APRS VIA ARISS and it should work with both birds. Since this time, there have been numerous attempts to totally recover the satellite, but further attempts have been stopped. NO-44 remains on and active when conditions are favorable for sunlight, usually in mid-day passes, although by the time it covers about 30-45 minutes into eclipse, power drops.
