Found this on the PSK31 reflector.
My crystal for the VXO has now arrived and I'm looking forward to being on
this mode after my return from a weeks R+R in HB9 land next week.

<< Subj: [psk31] Hunting Really Weak Signals

Here's a tip for anyone interested in hunting really weak psk31 signals.
I've noticed that the built-in waterfall is useful for displaying signals
weak enough to be barely audible, but no weaker. PSK31sbw can decode
weaker signals, however, and a more sensitive display is needed.
Suddenly my idea light came on...The Windows program SPECTROGRAM works
well for displaying super weak CW. Using a spectrum average of 4, I've
been able to watch a 2700 kHz bandwidth and watch for the familiar double
- line spectrum of psk31 signals. With a frequency marker traced on the
waterfall, I simply tune my li'l ATS-909 to place the signal on the
marker. When PSK31sbw is started, it is right on frequency...
So, if you're hunting DX, just use a good scope to find your prey!
