Might have misexplained it actually, the user has a Kenwood Radio that has
been played with prior to him getting the radio, had the deviation turned
way up, when he transmits on the 146.910 repeater to their input of 146.310,
he clips into my receiver at 146.325 causing the repeater to key up several
times during his conversation when he speaks loud into the microphone. I
even offered to adjust his radio for him, says he would like that, but won't
make the attempt to bring it here to get it done. Just was hoping to
eliminate it on this end, which I had with the Mastr receiver until I
installed the preamp, then he came back, but the suggestion of using a pad
might do the trick. He generally gets on early afternoon, so once he begins
his transmissions, I will put the attenuator inline and see how far down I
have to go to get rid of him then check receiver performance from that
point.
