Hey Kevin,
This repeater you are having trouble with wouldn't happen to be the
2 meter machine on 145.16 output and 147.71? If it is, you are 10
KHz away from the adjacent channels that are co-ordinated. You are
also 5 KHz from the adjacent channel of a co-ordinated repeater
input.
What were you thinking??? Umm......turn that junk off NOW!!!!! I
think YOU are higher than your insertion loss.
