If the signals of two repeater transmitters mix together in one or both of their final amplifiers and unwanted signals at the sum and difference frequencies of the original signals are generated, what is this called?

How does intermodulation interference between two repeater transmitters usually occur?

How can intermodulation interference between two repeater transmitters in close proximity often be reduced or eliminated?

If a receiver tuned to 146.70 MHz receives an intermodulation product signal whenever a nearby transmitter transmits on 146.52, what are the two most likely frequencies for the other interfering signal?

What type of circuit varies the tuning of an amplifier tank circuit to produce FM signals?

What audio shaping network is added at an FM transmitter to attenuate the lower audio frequencies?

Which type of filter would be best to use in a 2-metre repeater duplexer?

The characteristic difference between a phase modulator and a frequency modulator is:

In most modern FM transmitters, to produce a better sound, a compressor and a clipper are placed:

Three important parameters to be verified in an FM transmitter are:

For a repeater to operate automatically, the circuit that determines when to turn the transmitter on and off is the:
