• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

Does Wackanut still do security out there? Or did the TSA take that over? What I am trying to ask is who uses the security channel out there TSA or a private company?

Last I knew HSS (Hospital Shared Services) did security out there. They use a TG on the DIA system. I believe TSA uses a different one. Anyone?

Yes, HSS does the security at DIA. They came by and introduced themselves to me at least 5 times today at the airport... "Sir, what are those radios for? Um... the listen to the airplanes that are at the airport! Oh?" They are the users of the Security TG on the DIA TRS.

The TSA use radios that run APCO25 at the 170Mhz range =)

This is the TSA frequency list from the wiki:

http://wiki.radioreference.com/index.php/Transportation_Security_Administration

Ch Frequency
1 172.150 = S1 simplex [APCO-25]
2 172.150 = S1 simplex [APCO-25]
3 172.150 = S1 simplex [APCO-25]
4 172.150 = S1 simplex [APCO-25]
5 172.900 = S2 simplex [APCO-25]
6 169.300 = S3 simplex [APCO-25]
7 172.900 = R1 repeater (169.300 input) [APCO-25]
8 172.900 = R1 repeater (169.300 input) [APCO-25]
9 172.900 = R1 repeater (169.300 input) [APCO-25]
10 172.900 = S2 simplex [APCO-25]
11 172.900 = S2 simplex [APCO-25]
12 166.4625 = F1 simplex with 103.5 CTCSS [Analog]
13 166.4625 = F1 simplex [APCO-25]

I would try those and see if anything comes up. I know for sure that 172.150 and 172.900 are used at BWI in P-25 mode.

Thanks, I didn't realize TSA has its own tunked system. I thought everything used the DIA EDACS. When did this go in? Is this something that is nationwide at all TSA sites?

I believe the frequencies are available for TSA use nationwide. It is not a trunked system. It uses APCO-25 digital over conventional VHF frequencies. I didn't hear the repeater in use when I was at BWI and I didnt get a chance to monitor at DIA so I dont know if they have the repeater from that list set up for use.
