I have two Yeasu H/T's (VX-6 & VX-7). I just replaced battery in both. Now, without doing any programming tweaking, neither will receive on duplex, but will transmit & hit the repeater(s). In simplex, both transmit & receive perfectly. I have done a factory reset on both, and reprogrammed using "CHIRP". No change. Hits repeater, but I cannot receive. Offesets and tones have been verified. They have not been dropped. Any suggestions as to what I might try?
