The way Unication pagers works is that first off, you need to have all the frequencies from a site/system programmed.
Then you need to tell the pager, the talkgroups you want to listen to.
If you have a Premium subscription to RR, this is easy to do. Got to the system you intend to listen to and download both the talkgroups and trs (trunked radio system) info.
The above said, is if you are programming your pager for a trunked system. It will be different if your intended listening target differs from that.
Like someone said above, it does involve A LOT OF TWEAKING. Hang in there, do your homework, search, ask. The rewards are great.
To answer your question, no.
Just loading your County Sheriff Department, doesn't enable you to listen to what you want to hear.
Sure you can, but, do you?
You want to be able to be selective in your scan, besides, there are talk group limitations.
You can listen up to 64 talk groups on one knob, so, you need to be judicious and choose the most important talk groups to you, to program into those knobs.
Does it starts to sound complicated to you thus far?
It is, for the uninitiated.
Is it impossible, of course not.
You can do it, it takes a while to figure things out.
You need to have a basic understanding of the systems you want to listen to and your chosen pager.
Unication pager lineup offers several pager across different radio bands. Settle on the one you need.
Then study the system you WANT to listen.
Trunked digital systems use multiple frequencies the radio needs to scan in order to give you the audio from transmissions.
The radio listens to a Control Channel frequency, which in turn, tells the radio to listen to the actual frequency where audio is being broadcast, as long as you have the talk group you want to hear audio from.
There's an option to listen to everything and that, is another option you will need to decide on and program, the radio doesn't do anything automatically for you unless you program it, and, as you might have guessed by now, requires you to do your due diligence and study your system and the software needed to program the pager (PPS).
