state police/highway patrol

[mlevin]

will be traveling through the state in july.anybody know the freqs for the state police / highway patrol?are they trunked or conventional?any info is helpful.

 

[Truckiee23]

158.985, 159.000, 159.1350, and 159.1650
You will have to scan these frequencies depending on where you will be. VSP uses these all through out the state.

VSP uses those 4 frequencies to get 14 channels by using PL tones... if you have a scanner that has that feature you might want to program the frequencies in that way for less interference. There are 7 divisions. Each division has 2 channels each.

 

[garys]

What type of scanner are you using? I have an Excel program for use with Andy's 780XLT programmer that has most of the VSP info on it.

To cj's list add 154.665 and 154.695 for car to car Tac.

 

[mlevin]

whoa! wait a second whats a pl tone,i'm going to be using a 250d and/or pro94.do you know what divisions use which freqs.thanks for the fast response.

Review the above for PL's but they are not necessary because each division and unit is broadcast at beginning of communications.

thanks alot frank for the link i got everything i needed off of the site

Input Frequencies

Hello all. With regard to the VA State Police info page in the database section, what are the "Input" frequencies for?

 

[paul34]

Virginia SP operate on a conventional repeater-based system. A repeater is a receiver/transmitter that operates at fairly high power, and is usually situated on a tall tower or hill (or a tall tower on a hill) so that it has a large coverage area.

Individual user radios transmit on the repeater input frequency and receive on the repeater output frequency. The repeater receives on the input frequency, then rebroadcasts on the output frequency.

Why? Well, VHF pretty much travels line-of-sight (you can get some reflected signal over the horizon, but don't count on it). From one car to another, without using a repeater you could only get reliable communications over a 4-7 mile radius (distance to the horizon). Since the repeater antenna is much higher than the antenna on top of the vehicle, it can receive over typically a 20-30 mile radius. Plus, the repeaters can be linked through land-line connections or microwave links to give effective coverage over a much wider area.

Some of the implications for scannists:

• 
  * If you want to conserve memory, only program the output frequencies.
  
  * If you want to take special notice of nearby units, also program the input frequencies (if you hear something on one of these, the source is typically only a couple of miles away).
  
  * When listening on the input, if you do hear a transmission, it is typical that you will only hear 1/2 of the conversation (the half coming from the source near you).

Thank you very much, Paul34. Very informative!

What is the input frequency for the repeaters?


I think i have found the question to my answer: :lol: . . .

154.905 - State police, input to 158.985
154.935 - State police, input to 159.000
155.46 - State police, input to 159.135
155.445 - State police, input to 159.165

What are the input frequency for the repeaters?

paul34 explaned their use and my link above and RR Datbase list the input freqs for each output. But also stated previously, if you scan the output, you'll hear both sides of conversation, while input may only give you one side.

Example, the Wytheville repeater is on a very high knob on Clinch Mountion in the SW part of the state. Talk about range...
input 154.935 match with 159.000
input 155.445 match with 159.165

I believe Appomattox, Salem and Culpeper also use a mountain tops.

For better coverage, the VSP uses many different repeater sites linked together via a microwave backbone. For example, Channel 1 is repeated at sites in Bon Air, Dinwiddie, Louisa, and Powhatan.The dispatcher can transmit on any which one they select. There are remote recievers at these locations as well as in a few others. All this guarantees that the system, ergo- the dispatcher can hear a unit if they transmit-with some degree of clarity. As with any radio network, there ARE dead spots, but if it becomes an emergency, the user may select a different channel and reach a communications center.

The State Police tend to leave the repeaters on most of the time and both the base and mobiles may be heard on the base frequency.

 

[MOTORHEAD3902]

Good listing. If I think of it, I'll try to put my hands on a map of repeater sites throughout the divisions and see if I can get it scanned. A note on VSP radio channelization, though,channel 13 is no longer used, as there is no longer a separate dispatch facility in Melfa. Area 31 is now covered on channel 9 Chesapeake. It has been this way for some time now, and the only folks you'll hear using the input combination for channel 13 are the radio techs.
But i do remember the old KIC825....

Hello,

Do channels 7 & 8 (below) coverage areas overlap some on the joint I-77/I-81 stretch going through Wytheville? Where exactly does the channel 8 start covering I-81 around Wytheville? Am I correct that channel 7 covers all of I-77 from NC to WVa? Any good Wythe county sheriffs frequencies also appreciated.

Wytheville also has base repeaters on Big Walker Mountain, Whitetop Mountain,Big A Mountain, High Knob Mountain and Hunter Lookout Mtn In Lee County in the far western part. There used to be one at Beamer Knob but I am thinking it was moved. They blanket the area fairly well in SW Va anyway.

Have fun monitoring on your pass through!

Suggested Scanner Channel Plan

If I'm going to be driving through a large section of Virginia, I set up the scanner with each input frequency followed by the corresponding output frequency. I lock out all the output frequencies. That way, I avoid hearing about traffic situations far away. If one of the mobile (input) frequencies comes alive, I hit manual (twice) to get on the appropriate base frequency. If there's reason to keep an ear on that traffic, I would then unlock that base frequency and scan.

Of course, I'm also scanning Tac, Surveillance, and SIRS
