Amazing enough, PCSAT2 had a normal packet BBS on 435.275 down and 145.825 up with the callsign of
MAIL-1. One use to be able to access it at 1200 or 9600 baud, though
the link was better at 1200 baud.
Not sure what its replacement was, might have been a picosat and is now using:
Downlinks: 145.825 MHz 1200 baud packet and 435.350 MHz PSK31 and SSTV
USNAP1: . . 437.605 MHz 9600 bd TLM once every 30 secs from sister cubesat BRICSAT2
Uplinks: 145.825 MHz narroband FM packet and 29.4815 MHz SSB PSK31
