what are you mumbling about richard? doppler direction finders operate at
audio frequencies and since the detector and switching system operate from
the same clock they are perfectly accurate... at least as well as you can
calibrate the phase reference between the demodulator and clock.

hello dave,

same thought here..i wish to use 2.4ghz as my carrier and a doppler
shift in the kHz range.
any recommendation on good FM receivers in this frequency?
thanks

To give you 10% resolution will require it have its local oscillator
accurate (and stable) to one part in 100 Billion (of course, same goes
for the source). Hmm, maybe Bang & Olufson....

Laser interferometry would be simpler, and probably cheaper too.
