Here's my continuation of the carrier plot,

using a frequency of 137776.999810 Hz.

I wondered what that glitch was.
No obvious peak on Edgar's animated spectrum. I like
those animations, I just load the file into mplayer
and step through a frame a time.

Does this frame show the beginnings of a peak?

Probably not, it's off frequency too much I think (~-1mHz) and too
broad. No hope of coherent BPSK messages unless we see a sharp
10 or 12dB spike on there.
