Hi Tim,
Might the RX be hearing the TX?

I had this on a Mastr II and solved it by adding a resistor across the audio
input to the exciter - I think I used a 100K, but you could experiment. It
originally sounded like squelch noise leakage, but it wasn't.

Yes, it has a stock Motorola PL encode board. I think the noise was there
before I installed it.

Has the noise been there all along?
It may be just the nature of the beast.
There is an article on the RB web site about modifying a mobile audio
squelch board to work in a base/repeater station, one of the benifits to
doing so is the better muting of audio from the receiver, this is
because

I believe he said that with the controller disconnected, and using local
PTT, it still does it. That should take the receiver completely out of the
equation, leaving only

That's why I suggested trying to add some resistance across the mic high and
low at the exciter.

Would the same apply to an MSF2000 base station converted to a repeater?

Chuck, I did over look that part about being disconnected.
