Hi I have a BC 796D base scanner. I have a channel that is a digital channel and was working fine. I unplugged it and brought it home and now there is an issue with that channel. It just makes the horrible squelch/nasty sound when ever they key the mike. I didn't touch anything on it and am not sure the issue. I do know that the P-25 card is enabled and that is on. It is a UHF 450 range channel. I appreciate any help. Not sure what the setting should be or how they could have been changed from just moving it. Never had a problem doing that before. Is it possible for the digital card(p-25) to go bad? thanks in advance.
