FBI monitoring

[SA_tx_88116]

Like they’ve all said, you never know until you plug them in and listen. I thought I wouldn’t hear anything from Border Patrol in January when I started focusing on the Federal Band, but I’ve found plenty to listen to in the clear, even and especially on simplex Tac channels.

Just heard a transmission from CBP DNET 202 it was encrypted through and it sounded like it was reapeated if anyone ever heard this channel in the clear what is it used for? Frequency: 172.0625.

Could be just about any customer of CBP's NLECC - they do allow a multitude of agencies to share/use the CBP Network.
Here in New England we have heard FDA and NMF (others but just to show who you might hear) in addition to the normal C, BP and ICE users

I guess you mean that Presidential Protection Division is only one part of the USSS.

Correct

The Secret Service has primary jurisdiction to investigate threats against Secret Service protectees as well as financial crimes, which include counterfeiting of U.S. currency or other U.S. Government obligations; forgery or theft of U.S. Treasury checks, bonds or other securities; credit card fraud; telecommunications fraud; computer fraud, identify fraud and certain other crimes affecting federally insured financial institutions.

Depends - remember the USSS is not the Presidential Protections - but YMMV as to ENC
Only you can confirm ENC vs CLR in your reception area

this should have been "is not just the"

And don't just rely on what is in RR, you are best to SEARCH 162-174

And as said before on many another thread(s) - Federal activity is NOT like listening to your Local PD/FD/EMS
activity may occur daily, it might be weekly, monthly or once every two years - just keep listening/searching
and take copious notes

Best way is to use an SDR to cover a wide bandwidth. Do screen captures every 20 seconds or whatever, stitch those into a movie and ply them back when one have times. Not that hard to do and nothing beats this for finding signals and you can do the captures when you are not home.

I spent a good six months last year monitoring all the fed feqs in the database for Bexar. Plus, searching the VHF and uhf fed bands. CBP is pretty quiet, mixed clear, and encrypted. Same with ATF, not much traffic. Secret Service used to do weekly radio checks in the clear and encrypted from the SA field office channel on 165.2125, but I haven't heard that in a while. Every FBI simplex or repeater I ran across was fully encrypted. DEA was the most active. Next to Border Patrol and ICE. But at times, a whole conversation would be fully encrypted. So, like everyone else is saying, it's just a gamble and timing. And a lot of them just use simplex so you have to be within a mile or so usually. I know many of the feds around here use the AARRS for task force ops.

The closest thing to daily radio traffic would be the FPS at the downtown federal building. They are mixed clear and encrypted on 410.800

My scanner picks up signals from the c100 comms center but I get no sound probably because I’m using an indoor antenna. You also mentioned DEA as most active but I never heard anything there same with ICE. I can’t listen to AARRS because I believe they use digital simulcast and only an SDS radio can pick that up and I only have a RadioShack pro 197. Possibly an amplifier would help?

AARRS is a phase 2 system and the Pro 197 lists only phase 1. Depending how the system is running, you may or may not be able to decode anything.

Understood I just listen to LCRA digital p25 phase 1 tgrp’s

My friends and I used to listen to the FBI on 163.9625 back in the 80's All of a sudden they disappeared and we never could figure out where they went.

I also used to listen to the Secret Service's main channel on 165.37. Some of it was encrypted, some wasn't. They even had a backchannel set aside for the agents that guarded Bush Sr's house (I think it was 165.785). I'm pretty sure they're not on those channels anymore

163 became the input and they moved the repeater output to somewhere between 166-174

TXDispatcher1 didn't mention the location. The Dallas FO move the 163 MHz repeaters in the late 80s or early 90s. The repeater here swapped input and output frequncies. Then they changed everything again when they went digital about 2010.

Yea, I meant Houston. I searched the federal bands a zillion times and could never find them after they disappeared from 163.9625
