Just curious if anyone knows anything about this situation - there is a
gnu licensed project on sourceforge called DReaM. A fellow named Cesco,
HB9TLK, created a ham radio version called WinDRM
( http://n1su.com/windrm/docs/1.1/ ) derived, so they say, from DReaM,
but at far as I can tell, there is no source code available! Just
running 'strings' on windrm.exe you can find fftw 2.1.5.
Anyway, thought this was interesting - a baudline spectrum of
off-the-air HamPAL (DRM) picture swapping session:

you can just make out the spectrum bands shown in Robustness mode E /
Spectrum occupancy 0 as described here:

particularly the frequency pilots.
