Looking in the RR database, there are talk groups listed for Caswell County but there are no frequencies. What does this mean and how do I determine what frequencies to enter?

If you are talking about VIPER talk groups you have to enter the nearest VIPER tower freqs.

I don't know anything about your area as far as geography so I can't help you out there. But when you figure out what your closest tower is then you'll enter the talk group IDs into that system.

The information in the RR database is dependent on input from radio hobbyists. If no one has reported an operational Viper site within Caswell County, there might not be any working sites yet.

That would not necessarily prevent someone in Caswell Co from using the Viper system ... if their Viper radio can "affiliate" with a Viper site in an adjoining county.

There are two Viper sites licensed for Caswell Co ... both are located in proximity to Yanceyville. One is on County Home Road; the other is on Hwy 620, about 8.7 miles south of Yanceyville (according to the license).

If you can hear the control channel of a Viper site, it's a pretty good indication that the site is either operational, or close to being so. Most of the Viper sites use the highest frequency licensed to the site as the primary control channel, so try programming these two frequencies in your scanner in a couple of unused memory slots ... and then listen to each frequency unsquelched in "manual" mode.

If you hear a continuous sound similar to a machine gun, you're hearing the control channel data. Program that frequency as the control channel for a Motorola type II system, in accordance with the model of scanner you're using. You can monitor the system in "search" mode without entering any talkgroups.

Here's the two likely control channel frequencies for the Yanceyville sites:

------ 868.975 MHz / County Home Road
------ 868.8375 MHz / Hwy 620

Keep in mind that you might also have good reception of a Viper site in a neighboring county, so check those control channels for reception.

Here are links to the FCC ULS licenses for the Yanceyville sites, in case you need all the site frequencies to program your scanner:

ULS License - Public Safety Ntl Plan, 821-824/866-869 MHz, Trunked License - WQDE988 - NORTH CAROLINA HIGHWAY PATROL

ULS License - Public Safety Ntl Plan, 821-824/866-869 MHz, Trunked License - WQET823 - NORTH CAROLINA HIGHWAY PATROL
