In order for anyone to help you with this, you'd need to specify what radio or software this involves, and are you trying to enter a frequency? Or some other number?
The radio brand is UV-5R5 made by Baofeng Corporation. I have figured out the answer to this question, though, in the TDR. Except that the channel is fuzzy most of the time. That is the only problem now. I do not hear the communication.
It sounds like he might have a radio that has dual VFO channels, usually used for cross band repeaters. Like Steve suggested,if you could provide us with the make and model, we can mot likely assist you or at least point you in the right direction.
