This may be stupid but i recently had my 1250 programmed for use at work, all of the channels in the zones work except for one of them. 153.62000 is the frequency for this channel 431 DPL, i tried to use it this morning at work and was able to transmit and my dispatch, and they could hear me loud and clear, but if i have the radio on scan i can't receive any transmissions for that channel . If i take it off of scan then the screen is showing that I'm receiving the transmission but i cant hear anything coming through. any ideas? your input is appreciated.
