CareFlite's newest birds by Augusta

Link to MedStar Posts(Mapsco Coordinates) in the Fort Worth Area

Here is the roundup of current medical helicopters operating in the area . (Thanks to Eric Ritzie 1/31/2005, and others 2/1/06)

Effective 2/15, Texas Lifestar, operated by Southwest Helicopters, will have a Bell 407 based at Wise Regional in Decatur. Some of you may know them as North Texas Lifestar but I was told they dropped "North" from their name. They apparently use Nextel for most if not all of their dispatch comms.

Air Evac Lifeteam formerly Critical Air has bases in Mineral Wells (Palo Pinto General Hospital), Brownwood (Brownwood Regional Hospital), and West (West FD)- All Bell 206L3s. Their radio system is linked to the dispatch center in San Diego and repeaters are leased locally- not sure from who- so no frequency info.

PHI Air Med has bases in McKinney (Airport), Corsicana, Fort worth and Dallas - All Eurocopter A-Star's (AS350). They are licensed on 159.900, 159.990(DCS 412), 154.515 and 160.140 (for Dallas/McKinney), 159.9675 (PL 186.2 for Fort Worth birds). Frequencies are licensed as Air Evac.

Careflite has bases in Dallas (Methodist), Fort Worth (Harris Methodist), Denton (Denton Community), Frisco (Frisco Fire Dept), and Grand Prairie (GP Airport). Most of the fleet are Agusta A-109's, but they still operate one Bell 222. CareFlite can be heard on the following frequencies 464.1 "CERN", 131.45 AirInc Dallas or "East", 131.675 AirInc West or Fort Worth. Also, 463.3, 454.075 will have some of the air stuff and ground ambulances.

Southwest Helicopters (N Texas Lifestar) operates a Eurocopter Twin Star (AS355) in Greenville and a Bell 407 in Sherman. I was told by one of their employees that they use Nextel.

Dallas Children's has a Sikorsky S-76 based at Love for neonatal/pediatric critical care transport- no scene responses. The transport team uses a 400 MHz LTR system licensed to Megahertz Technologies and also has an AIRINC freq of 130.125

Cook Children's in Fort Worth does the same with a Bell 222 currently based at Spinks Airport, soon to relocate to the hospital (within the next week or so). They are on a 400 MHz LTR system licensed to Netwave Communications and have an AIRINC frequency of 131.775

A little farther out- Air Evac Lifeteam has a helicopter (Bell 206 I think) in Wichita Falls that occasionally comes into Ft Worth with a patient. They are on 159.900. (DPL 032 - per Tom C.) No connection to PHI/Skymed.

In Tyler, Flight for Life operates a BK-117 out of Trinity Mother Frances Hospital and East Texas Medical Center (online article link thanks to Wally B.)operates a Eurocopter (Bolkow) BO-105 out of that hospital.

Several months ago I heard that either PHI or Critical Air was negotiating with the hospital in Mexia (Parkview Regional) about placing a helicopter there, but I have not heard anything lately.

Scanning CareFlite Communications (2/1/2006)

Careflite has a communications center at Grand Prairie airport. It is just north of their maintenance hanger at the north end of the airfield. It is used for CareFlite ground operations, Dallas air operations, Fort Worth air operations, fixed wing, and Johnson County 911 EMS call taking.

Since CareFlite left the TXU EDACS system, you can now hear a great deal of their ops on 464.1 PL 123.0 "CERN" Tower, 461.55, 463.3, 454.075(last 3 are LTR, but it's almost CareFlite traffic only). I recommend keeping the AirInc channels 131.45AM and 131.675AM programmed in, as they still have occasional use. The old dispatch channels 155.28 and 155.34 are also worth keeping around. Also keep in mind that CareFlite does much more than just the well known helicopter transports. 464.1 PL 123 is used for ground transports. If you're interested in the ground ops stuff, then you might check out the TeleTouch systems on

4/8/99 Rural Metro Web Page

9/2/97 Central Ambulance (Now called American Medial Response-AMR 4/8/99)

Ben, thought you might like some additional info on American Medical Response (AMR) freqs.

Central Dispatches from their administration on Inwood Road in Dallas. It is the base for all of the Dallas County ambulances operated by Central. Central also dispatches for the Hunt County and Collin County divisions from the same location. This is why there freqs are published as "Dallas".

Here are the specs:

463.8000 Dallas Ambulances 203.5

These units are identified as 3 digit unit ID's such as 115, 125, etc.

463.8250 Hunt County 203.5

These units are identified as Medic units. Medics 1,2,5,6 are based in the city of Greenville. Medic 3 is based in Commerce. And Medic 4 is based in Quinlan.

453.1750 Collin County 203.5

These units have been developed since I left Central as an employee. There are combinations of Medic and 3 digit ID's. Medic 7 is based in Farmersville and backs up Hunt County in overload situations.

Central also dispatches for the Hunt County Firefighters Association on 154.0100. PL 114.8. This includes all the city and volunteer fire departments in Hunt County with the exception of Greenville and Commerce. They are dispatched by their respective agencies dispatch offices.

Columbia Air 1 is dispatched on the Dallas freq, and will possibly begin responding to on scene incidents.

Just some info FYI. - Anonymous 10/19/97 - On 02/27/97 I wrote to tell you that CareFlite was building a new Communications Center at their Maintenance Hanger at Grand Prairie Airport. They finally moved in last week. Now all CareFlite radio is at one place. They kept all radio freq for now and dispatch from one location. All new radio, computer, & phone equip. No more dispatch at Dallas & Ft Worth Hospitals. The only change you can notice is 3 alert tones for standby & one long tone for a "go". Med 10 (462.975) is used for flight following on Dallas side because of repeater in Commerce. It is also channel for CareFlite ground & Dallas Ambulance which has VA contract.
