Markus,
Thank you, I hadn’t seen the spectrum plot; it more clearly suggests a group of six signals in a signal wilderness than the spectrogram does; and the spectrogram shows coordination between diverse stations and beautiful signal/noise diurnals.
I put the spectrogram in 4.5” x 8” on 11” x 17” black mat board, and am formatting the spectrum in 4.5” x 112” on 1’ x 8’ background.
Thanks to all for these great images.
73,

…
I think that Paul’s grabber’s 186 hour window with the six ~ 8270 Hz signals including diurnals and coordination is suitable for framing, a beautiful sight.
