I realize this is an old radio. I pulled it out to use in another vehicle. When I PTT on right side, it transmits on left side on same frequency and then receives on left and right side. (repeater). I have 146.700 on both sides. When I transmit on right side, I see no response from repeater on right side, but see response on left side. Transmit on left side, see response on both sides. Both have the same tone squelch activated with same PL tones. Been all over menus, but cannot find any setting that I can see or understand how to fix this. I APRS on left side and data on right side. Any help on this issue?
