An rtl based sdr should work. The internet seems to have several how-to's
to get them receiving APT. Thanks to the list, I've got my fcd playing with
wxtoimg via HDSDR (via CAT interface) vspMGR and virtual audio cable.
Satpc32 drives the rotators.
Only thing I learned is that rather than compensating for Doppler, make the
IF (58kHz) wide enough to contain the whole pass. It works where I am only
because it's RF quiet. Seems to be LHCP, too. At least that seems to be the
Do use a tripod or a omni. The signal level needs to be relatively
constant, or when the software tries to stitch the image together, a mess
is made. I can imagine a crew of wild eyed students pointing an Elk every
which way but up.
