TSA (Dallas, TX)

[SCPD]

Been playing Cat and Mouse with two TSA frequencies for the past few nights. But this Cat just caught the mouse.

TSA Dallas/Fort Worth International Airport: 169.1625 NAC: 128

I can't say if there is encryption in use or not. on the key up (several times now) I get the 128 NAC but no actual voice traffic. Either the TSA Agent has a low voice or he's keying the mic just for fun or I just aint catching the transmission. But I have been holding this Channel for about an hour now and it's showing a dedicated 128 NAC in Squelch search on a Pro-106.

Figured I'd pass this along to you Federal Scan folks - might help you narrow down TSA a little better in your area.

Does TSA Follow the Nationwide Channel Plan they use or is it site specific? I know that alot of TSA sites use 172.9000 with an input of 169.3000, i am unsure of the NAC, but i know that they use most of the same channels at some airports, but i guess it could be site to site, but check out the above mentioned freq and see if you get anything, It is the main Repeater freq at most airports.

The TSA does follow a nationwide channel plan for the most part, but they have deviated from it in a couple of cities. DFW airport does use some non-standard channels, 169.1625 and 169.1875 reportedly. I have heard 169.1625 being used at Chicago O'Hare also, but have not seen it used much of anywhere else.

This is the first time anyone has posted a NAC for the DFW TSA - thanks!

I have heard that you have to be relatively close to the airport to listen to the repeaters, i know where i am they use 172.9000, but i have a pro 96 so i can't search the NAC, i am not sure if they are like the rest of the FED Agencies who use a standard NAC like 167 such as the FBI, I think that NTSB and FAA use standard NAC's for I/O, i am not sure if they use that for TSA too so they don't have to get all crazy programming the radios, i am pretty sure that FAA, NTSB and TSA are all VHF P25 and Analog, I also heard that most, if not all FED Agencies are moving to P25,

I've had those two TSA non-Standard frequencies in the scanner for a while now. I got a hit last week on it but was mobile and when I looked down at it, the radio went back to scan. Last night we had a Great band opening so I closed everything except my Gov list and low and behold! TSA became very active, mainly between 5AM and 6:30AM Central. I bet they were changing shift and conducting morning radio checks. I also have VA Hospital Bonham Texas using 407.5000 NAC: 293 for both Maintenance and Police. But VA Bonham is a smaller facility compared to most. And I get A LOT of activity on FBI-1, 3 & 5. some encryption and some in-the-clear and all still with a 167.9 PL.

Sitting in the parking lot at the airport in Milwaukee, WI, earlier this week I heard what I believe to have been the TSA on 172.1500 NAC 2 in the clear. The content of the traffic was consistent with it being TSA, e.g., "Red sweater, center lane".

I also heard what I believe to have been encrypted TSA on 169.300 NAC 9 from the same location. Sounded like someone with a mouthful of marbles.

From that same location I heard an analog transmission on 406.5375 in the clear which I believe to be the USPS. There is a major USPS facility near the airport.

From a different location I heard a 2:00 p.m. net rollcall on 406.200 NAC 201 which I believe to be the Federal Protective Service. Also on 409.9375 NAC 482 I heard what I believe to have been an encrypted USPS transmission. Also 167.2250 PL 162.2 in the clear -- DHS?

i know that 169.3000 is used as an input for 172.9000 for TSA, i am unsure of the NAC, 409.9375 i have noted P25 activity in new york city and Nashville TN, I beleive it's US Postal Inspectors and Postal Police mixed, in NYC i remember that the dispatch was in the clear and the field was encrypted, in nashville it was full time DES, the federal protective service usually uses 417.2000 with 293 NAC, i heard that the FPS was dispatched on a linked system all the way from philly, through boston covering the NY, CT, MASS facilities they service, i don't know if anyone here can confirm that?
TSA might use 169.3000 as a simplex freq, but i know for sure it's a repeater input TX freq,

TSA is all digital, NTSB is almost all digital now, and FAA is all digital except on the VHF/UHF air freqs.VA police are still mixed analog and digital depending on where you are. FBI is also still mixed, but is quickly converting to digital, and mostly encrypted, though there are a few ops still in the clear.

I have monitored TSA here in INDY for a bit, and noticed most of the time you need to be pretty close to the airport due to low powered ops. Though I did hear one conversation between a agent at the airport and one mobile coming in from Chicago, and from quality of the sound, was iether a band opening, or some of the units have mobile extenders.

i know that 169.3000 is used as an input for 172.9000 for TSA, i am unsure of the NAC, . . . the federal protective service usually uses 417.2000 with 293 NAC . . . TSA might use 169.3000 as a simplex freq, but i know for sure it's a repeater input TX freq,

I had a number of hits on 169.3000 NAC 9, but wasn't getting anything on 172.9000. I'll try it again the next time I'm near the airport.

Confirmed the 406.2000 NAC 201 again today. Net with rollcall each day at 2:00 p.m. three days in a row. Shortly after the rollcall today there was a call to the dispatch reporting that an alarm was a false alarm. Seemed consistent with what FPS would be doing.

Whoop's, Got another one!

TSA Ch-05 172.9000 NAC: 128 Pretty active too. But very brief convo's. In the clear also. I suspect its TSA at Dallas Love Field Airport, but can't 100% verify that.

Edited at: 0837 This is the NAC for the TSA repeater at Dallas Love Field Airport. The TSA agent asked someone to meet him at a Specific street on Airport property.
