Nice Uniden Feature

This morning I turned on my GRE PSR600 receiver to listen to my local P25 system. No traffic. No "T" was being displayed so I knew it wasn't receiving the control channel. So I analyzed the system frequencies and no active trunking channel could be heard. I then tuned to 866 Mhz and searched upwards until I found the familiar sound of that Motorola P25 trunking channel. I then copied the new frequency into that P25 system frequency list and it worked.

So I figured I would have to do the same thing with my BCD396XT. But to my surprise I didn't have to do that ! Within 3 seconds it found the new control channel frequency all by itself and automatically entered it into the site's frequency list and started scanning. Neat. Another nice Uniden feature has and the GRE didn't. Now my curiosity question is how did the BCD396XT know how to find the new control frequency by itself since it wasn't receiving the control channel at all ? And how did the 396XT know it was the correct new control frequency for that particular P25 system to monitor for activity ?

Are you sure that it wasn't already programmed into the scanner? If you are using a program like ARC XT and RR downloads, you'll get all of the possible control channel frequencies in the download.

This is a new frequency that was just activated today. It wasn't on the air yesterday. It isn't in the RR database just yet. Like I mentioned in my post I found it by doing a manual search for it. I'm curious how the radio "knew" where to find the new control frequency and enter it in the site's frequency list.

I really doubt the Uniden scanner magically pulled the frequency out of no where. You either had the frequency in the Uniden and not in the GRE scanner or you updated it and not the GRE. I know you said it was a new CC that had just came online, but that is not possible for the scanner to somehow get a new CC out of thin air without at least first getting some CC info prior to a new CC coming online. The only thing I can think of is the Uniden somehow goes through all the CC's programmed in then decides to do a search by itself when it doesn't find a CC to decode, then finds the CC that matches NAC WACN and whatever else then adds that into it's CC database.

Of course the Uniden scanner didn't magically pull the frequency out of nowhere. Maybe the old CC channel contained some kind of data that instructed the scanner to add the new frequency ? After all, it did take the scanner about 3 seconds to find and then to change to the new CC. Interesting.

Not possible.
