During the 1940Z pass, 7 degrees max elevation over the Pacific, I ran both Warbler and SoundModem ver 0.83b. SoundModem captured slightly more than twice the frames that Warbler captured ( 14 vs 6). I did have to un-tick the non-AX.25 filter option in the SoundModem settings for BPSK AX.25 1200 baud.

Thanks to all the responses to my BPSK demodulator query.
