Sounds like the scanner receiver is the problem. (You'd have to have
some really weird transmitter circuitry for it to emit on those three
frequencies.)
Make sure the transmitter and scanner aren't too close to each other --
you don't want the transmitter signal getting into the electronics of
the scanner and you don't want to put too much signal into the scanner
receiver, if you overload it then you're going to get all sorts of
modulation effects (that is, apparent signals will show up all over the
spectrum).
Its helpful to know the relative strengths of the signals.

Our club purchased a scanner. We are using a program on the scanner
which gives primary freq and + and - 455 image freq.
When a tx is turned on the scanner picks up these image freq as well
as primary.
I am thinking these are generated by the rx not the tx.
Are they a problem? Am I correct?
