Default Speaking of A.M. reception

Dont know Mike

I would suspect by itself I/Q detection/demod wouldnt help in a
situation where AM stations are using the exact same frequency.

Two antennas/RX detect systems could certainly be used if you can get a
usable phase diff between stations and use that for phase cancellation.
(ie not an I/Q RX as such) Could even do that in software and be very
specific as to what phase diff range is cancelled. You'd have to sample
at RF rather than AF though which makes the project more $/complicated.

You could also DSP filter based on audio content. That would be a real
difficult one!

Directive antenna?

Ok, how about the Tayloe detector, it has a strong front end and I and Q
outputs.
Anyway to use this to eliminate stations on the same freq. Maybe two
antennas and two
detectors phased or computer manipulated?
