The ISS ought to be on 145.825 for packet, unless they're doing something strange up there.

I don't know if there's any terrestrial APRS, or any other sort of 1200bps packet, but it's probably worth listening out for that to test your decoding.  Receive levels are surprisingly uncritical, but if you can get access to a deviation meter or service monitor to set up the transmit levels you'll get on a lot better.

Round here (NW Scotland) APRS has undergone a sudden and massive resurgence of interest, and 144.800 is extremely busy.
