[amsat-bb] Receiving MYSAT-1 telemetry

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!
