Question A-005-006-002

How does intermodulation interference between two repeater transmitters usually occur?

Correct Answer

When they are in close proximity and the signals mix in one or both of their final amplifiers

Explanation

If strong signals from nearby transmitters enter each other's final amplifier stages (which can act non-linearly if not perfectly isolated), intermodulation products can be generated and radiated.
