I can talk just fine but I can hear once. Seems like when I first turn the radio on I can hear for just a little bit.
Brand new radio. Other channels seem to work fine.
If that is the case, I would be sure you have the correct tones programmed in for both TX and RX. Sometimes, repeater owners will program different tones for the RX and TX frequencies, it will not always be the same tone for both.
Since other channels are working fine, I think it is safe to assume that it is not a hardware issue in the actual radio, which is a good thing.
