I saw his "bear claw" trace. It appears to be a carrier and 3+/- sidebands every 360 Hz or so. I suspect this is some other modulation method that uses 7 subcariers. bob

0230 UTC pass, saw the bear claw PSK 31 waveform again. Anyone else
able to see the PSK dowllink? I am seeing 7 parallel traces, almost like the transmission is overloading the receiver.
Attempting to attach the file to this email with a capture of what my

On a positive note, APRS is working perfectly on NO84 even at low
passes.
