Constant Transmitters

If you have a scanner, and have ever hit the lock-out button to avoid a terrible noise that never goes away, then you know what were talking about. There are a number of transmitters that you scanner can pickup 24/7, if you are close enough and in an area that is in the footprint of one of the transmitters.

There are a few advantages to listening to noise
(just for a minute or two)
  • Checking your antenna
  • Checking your scanner
  • Seeing if a different location or antenna yields better results
  • Seeing if a certain agency (that seldom transmits) can be theoretically received

Back in June we talked about Snotel, a low VHF frequency that is used to transmit thousands of miles by reflecting signals off meteors. Listening for this is similar but with the below frequencies you don’t have to wait on atmospheric anomalies.

Turn Off Two Way Radios?

If you’ve ever seen these signs and wondered why I must turn off my cell phone or two-way radio… here’s why. The obvious strikes many that something to do with a radio can possibly set off the explosives prematurely, however there’s a little more to it. Since the early days of blasting, blasting caps (small high percussion explosive devices) were inserted into higher grade explosives then feed back by a long wire to where an electrical charge set off the respective charges.

The most dangerous part of the preparation is when the charges are being laid out, and the chain of wiring is connected to each hole in the ground or structure. Particularly notable with surface mining and quarrying, the wire is “picked up” from the ground as illustrated below to add additional caps / charges.

When this occurs the wire acts as an antenna and can feed voltage down the line to the explosives and trigger the caps. With modern day advances DET-cord (plastic or nylon tube filled with lower grade explosives) acts like a powder trail vs a wire. Detonation Cord is less prone to the effects of RF radiation from transmitters and has many more practical applications such as joining, different speeds, etc.

Below is a chart depicting the maximum safe amount of RF energy in relevance to nearby blasting operations. Surprisingly the lower HF frequencies have the strongest effect around 10 MHz. Time Station WWV in Ft. Collins, Colorado operates 10,000 watts on among many frequencies, 10 MHz! Imagine being a blaster in that area,you would need to be over 2 miles away to avoid charging the wires with enough energy to theoretically detonate a blasting cap.

Glade Spring Head End

If you have Comcast and live anywhere in a good chunck of Southwest Virginia, then everything you watch on cable or utilize via the internet comes through this building.

The horizontal Yagi antennas are used to pick up other television stations digital broadcast signal and relay it back to the network for it to be rebroadcast on cable channels. The Microwave horn antenna that points back towards Walker Mtn and is not licensed for any frequency use below 10 GHz, it’s possible it once relayed data there or has been retuned to a license–free microwave frequency.

Attached to the corner of the building is a UHF Yagi that most likely was or still is used for 2 way radio communications.

Feed Stats courtesy of

We've seen a gradual increase again this month. There's been a lot of action and unfortunately a fair share of local tragedy as well. Remember the reasons we have these feeds, to offer you insight into news and important information as it happens. If one person is able to say they were not in the wrong place at the wrong time or made that interview on time because they didn’t take the interstate then we serve our purpose.
There’s lessons learned even in the worst radio traffic and many have advised this is a valuable learning tool for our region. Remember even deputies and troopers don’t get to pull dispatch tape when they “want to”.

The Media Section has been updated with several new recordings.

Perfect for anyone new to the hobby and an excellent refresher for us that have become a little rusty. This is the most up to date publication that effectively covers multiple radio services available.

I have been mentoring someone new to the scanner hobby and provided a little reinforcement. If you're wanting to test your skills, here are some sample tests I quickly drew up to make the subject matter a little more intensive.

Recent FCC Licenses UPDATED!(Next Update in January)
These are yet to be confirmed as active, however its not a bad idea to go ahead and program them in if live near their respective service areas. They have been hand picked from hundreds of new licenses.     FB - Base
MO- Mobile / Portable Use
MOI- Interconnected Mobile
FB2 - Repeater
FB2C - Repeater with interconnect
FB6C - Shared Repeater
FX1- Link to Repeater
FXO - Fixed

You can search for FCC
licenses on the
Research page.

  1. Norfolk Southern has many Microwave Link License Renewals (all not listed)
  2. The town of Coeburn has a new license for a repeater and 2 simplex channels, it is designated to be used for all town services (Fire, Police, Public Works), If you remember the town of Coeburn outsourced its Public Service Authority (water/sewer), It will be interesting to see if they are brought on board.
  3. Greeneville, TN has a new scada type microwave system to listen for, test your scanners range if you're in the area.
  4. O'Reillly Autoparts has a new license, it appears it will be simplex only, unsure how that range will work with the store on East Oakland Ave being in a fairly low spot and the frequency being UHF.
  5. RA Tech Services had a new repeater on Whitetop Mountain, CW (Morse code) Id has been heard from another repeater they operate from Whitetop for some time, however we heard no transmissions.
  6. NS Railroad licensed a UHF repeater pair in Grundy to use as a link to the milepost tower at 20 Mile Branch, This is unusual as they usually use microwave or existing railroad band frequencies for such tasks.
