When testing the electability of a signal, remember that no object is
anonymous in EM.  What you are hiding is your message, not your radio.  So
you would get a radio with high enough sample rate and sensitivity to
profile the emissions of your transmitter to your specific transmitter, and
see if your burst profiles could be reconstructed to recover the encrypted
streams.

Only somebody like a military specialist would ever be able to compromise a
signal that way, of course.
