Note: IM products can be minimized by use of band pass filters, isolators, notch filters and/or band-pass/band-reject filters.
Even order products are blocked by the transmitter low pass filter. Also the transmitting antenna has some out of band
attenuation of the frequencies coming back into the transmitter as received by the antenna plus any products produced in the
transmitter are also attenuated.
Testing: insert an attenuator at the receiver input with the issue (like 10 dB). If the signal is reduced by 10 dB, the IM is generated
out side of the receiver. If the signal is reduced by more than 10 dB, the IM is generated in the receiver.  If it is weakened
10-30 dB the IM is both in the receiver and an outside source.
