Guys This is a non-Kenwood two meter question. There is a lot of VHF knowledge on this reflector. I am VHF challenged. Question: Using a "Brand X" duo bander, I have trouble keying up one repeater. When I key the mike I get squelch. It happens on just the one repeater and not every time. All other freqs are O.K. If you have any suggestions please respond directly. 73, Archie, K4GA
