As far as I know receivers receive and produce no waves of any kind, but your questions are WAY beyond me. This is a forum about learning to fly not the internals of receivers. Not sure anyone will be able to answer your question here.

Standard procedure is to turn on the radio/transmitter before powering up the receiver.

You say servos are unresponseive but you don't say what sticks or controls you are moving to try and get a response. Which transmitter control maps to which channel depends on what transmitter you are using.

Those are FM receivers. Are you using an FM transmitter? is it on the same channel as the receivers? Do you have channel crystals in the receivers?

We need a LOT more information.

You may find some help here - Read the chapter on receivers and radio systems, then post your next questions and information.
