Interference from an adjacent/inband radiating source is
likely to cause the receiver's AGC circuitry to limit the
incoming RF signal to the point where the signal you're
trying to receive gets buried in the system's noise. Or,
the interfering signal is of sufficient magnitude so as to
simply "confuse" the receiving electronics.
Ghery, are you Insturment Rated, yet?
