hi Nick

a possibly stupid, unrealistic and very untested idea comes to my mind:
why not build a real AM radio in pd? in a subpatch with a very high
samplingrate (using [block~]-object) you could amplitude modulate the
signal you want to transmit. with a narrow band-pass filter [bp~], that
is tuned to the carrier frequency, you could get back the amplitude of
the original signal. maybe you add some [noise~] to simulate cosmic
radiowaves.
just a few ideas. i would be interested, if this approach has a chance
to work....
