At about 8 this morning, my 536 quit receiving a local NXDN. The system is still being used because I can still monitor it on my 436 and my TRX scanners. A few days ago, I had this same problem and the problem was the wi-fi dongle. As soon as I disconnected the dongle, I immediately began receiving the system. The dongle has not been reconnected since then. The radio does show a signal on the screen on 2 different sites, but it's like it has become deaf on this system only. All other systems in my scanner come in fine. What I have done today is clear user data, transferred the files back onto the scanner with no luck. I have also performed a factory reset of the scanner and reinstall the data and still no luck. I have tried the LCN finder and it will not find any LCNs. Even though what is programmed is correct because my 436 is programmed exactly the same way. So, does anyone have any other suggestions? Hopefully I will not have to send it in. I have had this radio less than a month and it was bought new. And also, this is the system I am trying to monitor, or should I say monitor again..lol Bay Minette, Daphne, Foley, Robertsdale Trunking System, Various, Alabama - Scanner Frequencies
