Thanks Jeff! Having someone to kick this around with is helping.
Very good point about the ratty user signal. I hadn't thought of that. You are exactly right. I need to make sure the controller is set up to always keep the transmitter up for a short time after loss of user signal on the repeater, and just kill the tone.
