I am guessing the switch is to comply with the Narrow banding that is taking place. I dont understand a lot about it so maybe you can help. I guess if they did narrow band you dont just subtract sum magic number to get a new frequency? Also to search for a new frequency on the conventional system I would do a stalker search on my Pro 106?
Thanks for all the help
I have a frequency counter, but the Unden 396 and Signal Stalker makes that unnecessary. I've been known to "hang out" in the area when looking for a target frequency, my job allowed it at times, but I would happen to eat in the same area etc.
But the good thing is the temp freq lockout, just scan and lock out that which is not highway related that should give you some good possibilities. Narrow-banding does not always mean changing frequencies, but if monitoring with the old PL tone, try it off or scan for new one, that may have changed as well. And try adding all the input frequencies too.
Also, these guys probably don’t use the radio much except for chit-chat, may be suing cell phones more.
