My scanner just stopped picking up channels and I don't see the trunking icon but it work in signal stalker for a few channels. I didn't do anything to it.
With all the rebanding going on it's possible the trunked system has changed its frequencies. Check the database and compare it to what's programmed in your scanner. I'll bet you see a difference.
Can you tell us where you are and/or what system(s) you are monitoring that stopped working? Over the past two weeks the Sacramento CA systems both rebanded.
If the system was rebanded, it is likely that you will need to do more than just change the frequencies in the scanner. The scanner must be told the system is a rebanded system. After we know which system we're talking about, we can advise you.
