Well Since the last newsletter, we've found new frequencies...
Here's a sample of what's new....

No field research this month due to the weather

Hear from Here

Live in Abingdon? Or Bristol, VA?

With Uniden's search and store feature we logged several months of transmissions, finding seldom used frequencies, new frequencies, and even clandestine (illegal) use of radios in the Tri-Cities. Having all the frequencies is great but knowing which ones are in range and actually being used is golden. By using our Radio PhoneBook database we built the following tables of frequencies for two locations for October. If you're a local this is what you can hear 95% of the time, enjoy!

GSM Security
Portable IMSI Catcher
Typically Constructed with a Laptop, Hard Drive (to handle the encryption tables), and a cell phone or commercial cell radio with an external antenna.

Many internet news sources are now reporting that GSM type cellular service is now easier than ever to intercept and even "spoof" with an imposter tower created from an inexpensive cell phone, laptop, and external hard drive. Critics have argued for years that the GSM service was vulnerable to interception and last year a commercial company began producing modestly expensive hardware to do just that. One such company, Rohde & Schwarz first began making "IMSI catchers" (IMSI International Mobile Subscriber Identity) in the mid 2000's. Equipment like this has been used by agencies since the first gulf war to deliberately hijack a cell tower and basically create your own tower to direct the calls to yourself, intercept and monitor, and then even redirect back to the tower to be connected to the phone network. Intelligence agencies have even taken the calls destination and rerouted it to a parties the caller assumes they are calling in this method.

If you have ever traveled internationally with a cell phone you have probably utilized the GSM service, most phones capable of use overseas use have a SIM card and use GSM to make the international connection. While stateside the phone would use a different frequency band and technology, sometimes (CDMA - Code Division Multiple Access) which by technology standards is much more secure and almost impossible to intercept and manipulate. Because of this vulnerability, customers will sometimes see thousands of dollars worth the calls on their cellular bill after returning from a foreign destination. This type of fraud is most common in Latin American countries. In these situations someone has used an IMSI catcher to clone your device or phone and then make calls at your expense.

In conclusion, customers that utilize GSM here in the United States are now extremely vulnerable to eavesdropping and cloning, more so in developed areas such as larger cities where the likelihood of someone with the knowhow and equipment may be lurking. With advances in internet connection speeds the sharing of the encryption tables may make even your local teen hacker capable of such feats.

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.
