Trouble picking up NC SHP.

[NCBubba]

I have a RS PRO-96 and have programed in the local troop C frequencies (42.6000 & 42.6600). The Dispatch comes in just fine but I am unable to receive any transmission from the cars. I must be missing something. Any help to find the cars would be appreciated.

If you are just using the rubber duck antenna, then you will only hear the cars if they are within a couple of miles of you when they transmit. Rubber ducks aren't the best for low-band VHF. The mobile channels aren't on a repeater, but, depending where you are located in the state, you might be able to monitor the remote receivers throughout the state that SHP uses to relay the mobile traffic back to the communications centers. Some of these are in the area of 72-75 mhz and there are some around 456-457 mhz. An example would 456.900 on Rich Mountain in Watauga Co. It relays 42.66 back to Newton. From my location in the Triad area, I can pick it up down here with an outside antenna. There is another one in Oxford that relays 42.66 back to Raleigh. However, SHP uses microwave at a lot of the remote receiver sites and they can't be monitored.

Here's a little help...

Tim,
Maybe this Win96 file will help get ya started monitoring the NCSHP on 800Mhz...Check out bank 4 (Smartzone) and ID 2096 (Troop C)...you will hear the dispatcher silmulcast of the VHF freq of 42.600Mhz and when the troopers call back in on 800Mhz you can hear that too...hope this helps you (and others) out

Correct frequency is 456.300 ... tone is 131.8 Hz.

Marshall,

Downloaded your file and cloned my radio. Excellent list of frequencies for the Triangle Area. I still do not hear much SHP traffic. In your listening experience, is there a lot of SHP traffic or is it minimal.

I don't think there's a whole lot of traffic from SHP. I don't think they call in traffic stops, they can check licenses/registrations from the computer, most public safety people use Nextel/cell phones for talkaround these days...

Other than 10-50 dispatches and those that choose to check DMV info on the air, there's not a whole lot going on, as far as radio traffic goes...
