11/29/2010 Obviously, I haven't kept this site as up to date as I did in the past. I think there is still some useful information though, so I'll keep it up. However, for more current frequency and talkgroup information, I highly recommend visiting www.RadioReference.com.
2/15/2010 Here are some of my notes on TXU/Oncor channels from monitoring the past few days. RadioReference has a lot of info too.
1/29/2010 Product Plug: I love FreeScan. I've been using it for about a year now, and it's awesome. "The award-winning Freeware program for programming the Uniden SC230, BC246T, UBC3500XLT, BC330T, BCD396, BC346XT, BCD396XT, BCT15X, BCD996XT, BCT15 and BCD996T scanners. FreeSCAN allows to download and uploading programming, remote control the scanner, log hits, and supports printing out of systems and groups. It will run on Windows 2000, XP, Vista & Windows 7." While it is "freeware", I encourage you to support it with a donation (After you've tried it, and find you like it, of course). The RadioReference download, other importing features and ease of use are excellent.

1/27/2010 White Settlement has purchased and placed into service a new Motorola trunked digital radio system, including new dispatch center for the fire and police departments and portable radios for every firefighter position. Mutual aid radios were installed in Westworth Quint 41, Lockheed Engine 27, and Lockheed Quint 29. Additional portable radios are available in the command unit for mutual aid companies.

1/13/2010 Nothing too exciting to report, other than I received my 4th Uniden BCD996XT today for use at work. I love these things along with the BCT15X. They're so much easier to navigate and have plenty of room everything there is to hear in our area.

4/6/2009 Here's a link to http://tx.scanamerica.us/index.php where you can listen to other people's scanners from around the country.

5/9/2005 CareFlite is in the process of moving off of the TXU 900MHz EDACS system to an UHF LTR Passport system operated by Teletouch along with 464.1 (PL 123.0) "CERN" and AirInc 131.45(Dallas) and 131.675(Fort Worth) channels for air ops. Good sources have it that the conversion should be done by the end of the month. From what I understand the Passport system is not scanable with scanners. The Johnson county LTR site will not be passport and will be used by CareFlite ground crews there. That system should be scannable.

3/3/2004 New Notification Service Available - www.AlertPages.com
2/16/2004 What are Squelch, CTCSS, DCS, DPL, PL, CG, DCG, and QC tones?
These subaudible(we can't hear them, but they're there) tones are used on some radio systems to eliminate interference and limit access to channels. In radio systems featuring tones, transmitters encode the subaudible tone, and receivers decode the tone. If it matches what is programmed into the radio the speaker is unmuted. If the tone does not match, then the speaker stays muted, thus preventing noise from interference and other users using the same frequency, but not part of the group of radios intended to be heard. Usually the encode and decode tones are the same, but they can be different. This makes it possible for a frequency to be used by more than one group of people without hearing the other group's traffic. If two people from different groups transmit at the same time, there may still be problems, but often there is enough distance and difference in time, that a single frequency can be used effectively by more than one group. Many repeaters use tones to limit access as well. Only transmissions with the proper tone encode will be passed through the repeater.

For us listening on the scanner, it is helpful to know the tones a particular group uses on their radios, so we can identify and filter out channels for ourselves.
The Uniden BC780XLT, BC785D, BC250D, BC296D, BC796D and some other scanners will search for squelch tones, and then if you want, you can choose to use those tones to hear only transmissions on a frequency with that tone. It helps to keep interference and transmission from other users from coming through on the channel you're interested in.

Thanks for the info to folks on the DFWScan Yahoo Group.

12/30/03 I just received my Uniden BC796D today, and so far it's great! It's pulling in Fort Worth NAS JRB's APCO25 UHF Trunked system from Bedford. It seems to be doing a lot better on UHF than a Pro-96 thus far.

12/28/03 Dallas Morning News article on Grand Prairie's communications plans. The current analog Motorola Trunked Radio System (TRS) will be going digital, probably in the first half of 2004 after all 3 towers are in service. It's reported that the second one is already in service that boosts coverage for the NW portion of the city. The third tower will enhance coverage in the south near Joe Pool Lake. Other dispatch center upgrades include cell phone mapping, laptops for officers, and a new center.

10/31/2003 Grand Prairie apparently is upgrading their Motorola trunked radio system (TRS). They've been using 857.9625 and 868.9625 running as a separate system while they test coverage. Others have reported that they will be going digital, and the testing I've heard confirms this. Decimal talkgroup 2192 on the test system has been analog, and I heard digital noise on 40688, but I'm not certain of that one yet. I believe one of these will be "Patrol 4".

Scanner Audio from the Stolen Truck Fire/Chase in Dallas 11/7/2001. Click here to listen. About 19 minutes into it(total 30 minutes play time, actual chase lasted a lot longer), the dispatcher advises that "800" (Tac supervisor, I assume) called for a "code 100", which I believe is an authorization to use deadly force as necessary to stop the suspect. This was recorded with RecAllPro (from www.sagebrush.com) and a BC780XLT on 460.5.

Fort Worth PS Trunked Radio System Notes (from a recent user meeting)
1. There are currently between 7,500 and 8,000 radios on the FWPS system.
2. There are plans to have 3 "TalkAround" Channels that will be mobile applications only and only good for a 3 to 5 mi range. The signal will not be on any logging devices. If the officer is on this channel and they hit their emergency status, NO base units will pick up the signal UNLESS their radio is programmed so that they emergency status is transmitted over their primary channel. From the way it sounds, these will be difficult to pick up by scanner. Someone else suggested that the 3 Bedford Direct Channels above might be used in Fort Worth as well. They are actually licensed to the State of Texas.
3. A new West Fort Worth tower project is in the works to take care of the radio problems in the west part of Fort Worth. It will be a 250-400 ft tower depending on FAA regs due to Carswell and the close proximity of the possible site. It is an estimated 18-month project.
4. Future planning to move 8 channels from the LGT to the PST system, simulcasting the LGT systems and rebuilding of tower sites.

Police Dept. Wireless Mics!
Here's a new one to me. Actually some folks on the DFW Scan List mentioned it several months ago, but I didn't try it out until today. I was able to hear a police officer interview a subject whose buddy had just shop lifted a grocery store. I searched between 169.0000 and 172.0000, and got a hit on 169.45, but I think I was using the wrong step. I should probably have been using 0.005 instead of 0.0125. Anyway, it was pretty interesting, and it's a good range to have programmed in for when you need it. The wireless mic is used with the in-car video camera to capture an incident on tape. They are very low power, so you have to be pretty close by to hear them.

What is Scanning?

Scanning is the hobby of listening to radio frequencies used by police, fire, EMS, aviation, business, or anything else that is 30MHz (frequency) or higher. Why Scan? It's fun! I've always been interested in knowing how public safety, aviation, and the media, etc. work behind the scenes. Listening to their two-way radio communications is usually the fastest way to know what's going on. Often you'll hear information that you wouldn't hear otherwise. I guess I started scanning in the early 80's when I was still dreaming of becoming a firefighter. Listening to where the fire trucks were going and what they said over the air was the closet I could get to the fire department at that age. I'm not interested in being a firefighter any more, but my interest in scanning has continued to grow. I appreciate dispatchers, firefighters, police officers, EMTs, and air traffic controllers much more because of scanning.


About Ben Saladino

Please don't take it personally, but please do not call me. I just don't have time to answer questions by phone. Much of what I know about scanning is available here anyway. You are welcome to email me to exchange frequencies and other information, but please see Ben's Beginners Buyer's Guide for Scanners, for help in deciding what radio to buy. If you still have questions, email me, and I'll see what I can do. Please do not ask me how to scan cellular telephones, or use what you can hear on scanners for personal gain (some examples, insurance adjusting and fire restoration, etc.). My understanding is that it is illegal to use what you hear on a scanner for personal gain.

Obviously I love scanning. I use or at least have 5 Uniden BCD996XTs, a Uniden BCD396XT, Uniden BCD396T, Uniden BC796D, 4 Uniden BCT15Xs, BC246T, Radio Shack Pro-97, Kenwood TH-D7 a Kenwood TH-78A, and 2 Kenwood TMD-700As, Kenwood UHF/LTR TK380. I also have an OptoElectronics OptoCom..

I'm now into collecting diecast fire trucks! One of my other hobbies is also a business.

My full-time job is at a bicycle shop. There I'm computer guy, inventory guy, office guy, truck unloading guy, salesman, and whoever else they need me to be. I do get to ride sometimes.

I have an associate’s degree in computer science, but most of what I use, I learned on my own. All of the above wouldn't mean a thing without God, my family and my friends.
