[FedCom] TSA/ 164.5375

Tue, 23 Sep 2003 15:55:06 -0400

Greats to both Ruff and my old friend Chris.

Hummm, in my notes I do not show either of the agencies mentioned TSA or
TIGTA for 164.5375. What I do show is this is a big DoI freq, owned and
operated by them. I show NPS BLM here with USFW being the primary user.
Again this isn't to say they would not authorized other users on their
freq, I just don't have a record. Of course, I am not doubting what
either of you have heard. In fact, I have just made a note in my notes.

  I have noticed several people hearing TSA traffic on 164.5375 all over

the country. Has anyone found the input? Any other associated freqs?

Ruff, I haven't seen or heard of anyone hearing TSA traffic on this
freq,
but I have posted this frequency as TIGTA, which is Treasury Inspector
General for Tax Adminitration, ( http://www.ustreas.gov/tigta/ ). They
seem
to have taken over for what used to be the Internal Affairs, or ORI. It
is
in use in the Portland, OR area, but I have not confirmed this frequency
for any other cities. The repeater inout frequency is 172.6375 mHz, and
all
traffic has been ASTRO P25 with no encryption.

I think the TSA frequencies have been pretty much established, and I
haven't found them on anything but the know frequencies so far, but I
guess
you never know...
Here is the channel plan of the TSA walkies:

 1-172.1500 S1 simplex (digital)
 2-172.1500 S1 simplex (digital)
 3-172.1500 S1 simplex (digital)
 4-172.1500 S1 simplex (digital)
 5-172.9000 S2 simplex (digital)
 6-169.3000 S3 simplex (digital)
 7-169.3000 tx 172.9000 rx R1 (digital) repeater
 8-169.3000 tx 172.9000 rx R1 (digital) repeater
 9-169.3000 tx 172.9000 rx R1 (digital) repeater
10-172.9000 S2 simplex (digital)
11-172.9000 S2 simplex (digital)
12-166.4625 F1 simplex 103.5 ctcss (Analog)
13-166.4625 F1 simplex (digital)
