Hi Ken!
Things certainly sound right from your description, but just for comparison sake here's an image of a MYSAT-1 packet as I was decoding from a recording some time ago:

... you might also want to check the "Modem Setttings" in UZ7HO SoundModem and make sure that "non-AX25 filter" is NOT checked. FYI, I normally leave "KISS Optimization" checked and "PreEmphasis filter" with "All" checked.

I've been trying to decode the 1.2k BPSK telemetry from MYSAT-1 (44045) without success. I'm using UZ7HO's SoundModem set for BPSK AX.25 1200 bd. The SDR is set to USB with 4 KHz bandwidth and the signal is strong with a 25 dB SNR. The received signal is right in the center of the soundmodem's waterfall between the upper and lower indexes for that BPSK mode. I'm obviously missing something here!
