How are your tones? About 90% of the packets on the air are overdeviated, distorted, skewed, unbalanced, not properly emphasized or demphaasized or neither. These work "fine" terrestrially when weak signals are not involved but may be 20 dB or more away from good performance with weak signals or picky receivers. I can decode PSAT with 5 bars on the Kenwood TH-D72, but have no other experience to compare. I remember good balanced tones did 3 bars on a D700, but typical bad terrestrial signals would not decode sometimes with all 9 bars!
The ear can tell between good tones (listen to ISS) and bad tones (listen to 144.39!)
We have a bgighawatt experimental air defense radar near Wash DC on tethered balloon blasting out power at 143 and 149 mHz and all over the place. I wonder if PSAT gets overloaded by that? PSAT does not listen to carrier detect, so when it has a packet to send, it sends it.

My packet setup gets digipeated instantly on terrestrial APRS networks, and works fine with ARISS, but even with overhead passes on NO-44 and NO-84, when I copy the birds well, I can't manage to get an APRS packet digipeated. Even if I crank the power up to 50 watts, using the M2 LEOpack antennas, those birds simply are deaf to me. I'm sending to CQ via ARISS, as my reading of the online docs seems to indicate that is appropriate. I've also tried CQ via PCSAT-1 and CQ via PSAT (for NO-84) but still no joy. I've also played with TX delay. Nothing works. What am I doing wrong? -- Mark D.
