Federal Acitvity at Mayweather Pacquiao Fight

On Saturday, May 2nd, what was touted as the Fight of the Century between Floyd Mayweather and Manny Pacquiao took place at the MGM Grand in Las Vegas. Due to the intense attention this event was bringing, there were some extra security measure taken, involving local law enforcement and even some federal agencies.



The TSA at McCarren Airport in Las Vegas was prepared for the onslaught of visitors to Las Vegas for the weekend of the event, as well as the flood of travelers leaving on the Sunday after the fight.

And it appeared that the FBI was maintaining some presence at the fight. On Friday, May 1, I heard several radio checks that seemed to come from near the fight location at the MGM Grand. I heard some references to downlink video being set up and heard one station ID as "Command Post". On fight day, I also hear some additional radio checks but nothing more. Fredquencies heard were 163.8875 MHz, N167 and 167.7375 MHz, N167.

I also heard some TSA units that were possibly on location at the fight venue, possibly members of the Behavioral Detection Unit (BDU). They were on 169.3000 MHz, N013.

Collecting Federal Radio ID's

In the May 2015 issue of The Spectrum Monitor, the Federal Wavelengths column featured my first attempts at collecting federal radio identification numbers or RID's. I've started a page here on the Fed Files Blog to collect and catalog the RIDs that have been collected. You can see a link to this page in the top bar of the blog home page, or follow this link:

http://mt-fedfiles.blogspot.com/p/federal-p-25-radio-identifications.html

I've just recently acquired a new Whistler WS-1080 scanner that displays RID's effortlessly, so hopefully I can add to this list more in the near future.

If you have any federal radio ID's that you would be willing to add to this catalog, just email me at the address on the blog front page.

March 2015 TSM Update/Correction

The March 2015 issue of The Spectrum Monitor is now available for publication. You can get a copy here: http://www.thespectrummonitor.com/index.aspx

In this issue I have some information on federal use of aviation resources and the frequencies that might be used. Unfortunately, one frequency got mangled in the publication process. The list of CBP AIR frequencies should have AIR 9 as 163.4750 MHz, N293.

You can check out the entire list in the CBP Updates tab on the blog home page: http://mt-fedfiles.blogspot.com/p/cbp-frequency-updates.html

FPS Atlanta Mystery

I am seeing reports on Radio Reference that the multi-site UHF trunked system managed by the Federal Protective Service (FPS) is not longer on the are in the metro Atlanta, GA area. Folks are asking what happened and where did the FPS operations go.

I haven't been down in the Atlanta area in a few years, but when I was there last, the Federal Protective Service appeared to be running a 4 site UHF Motorola Type II trunked system with both analog and digital voice. One of the subscriber agencies appeared to be Dobbins Air Force Base.
Here are the system specs as I had them:

FPS Atlanta
Motorola Type II
System ID - 750d
Voice NAC - N0d0
Site 1 - Atlanta
406.4125, 407.2125, 408.5375, 410.1250
Site 2
406.5625, 407.1625, 408.5625, 410.3625, 410.5625
Site 3
407.3625, 408.3625, 408.7625, 409.3625, 410.7625
Site 4 - Dobbins AFB
406.7625, 406.9625, 407.5625, 407.8625, 408.9625

Since my last time monitoring the system, it appears that Dobbins AFB has built out their own 380 MHz P25 trunked radio system, so they were no longer using the FPAS managed system.

Reports on Radio Reference include some VHF channels (173.7125, 173.9125 and 173.9875 MHz) that claim to be "TRS control channels", but are very weak in downtown Atlanta.

I suspect that if the FPS decided to dismantle the trunked system, they have probably returned to conventional UHF channels, most likely APCO P25.

Can anyone in the Atlanta area offer any further information?

UPDATE:
A listener in the area reports that the FPS is using 410.8000 MHz, N201 for their operations and has been for some time now. I checked my logs from my last trip to the area in 2012 and I did not get any hits on that frequency.

October 2014 Federal Wavelengths Correction

A sharp-eyed reader just brought it to me attention that there were a couple of errors in my listing of the frequencies used by the Environmental Protection Agency (EPA) in the October issue of The Spectrum Monitor magazine.

By all means, if you spot something with any frequency lists either here on the Fed Files blog page or in the pages of The Spectrum Monitor magazine, please feel free to let us know about it.

Here is the corrected list showing the correct EPA repeater input and output frequencies:


ZONE 2 – EPA Repeaters



Repeater Output   Repeater Input    Channel Name
173.8750, D731    166.4750, D731    EPA REPEATER

170.9750, CSQ     168.7000, CSQ     NI/CG REPEATER 1

170.4500, CSQ     168.1000, CSQ     NI/CG REPEATER 2

170.4250, CSQ     168.0750, CSQ     NI/CG REPEATER 3

168.4000, CSQ     166.6125, CSQ     NI/CG REPEATER 4

169.7500, CSQ     167.1000, CSQ     NI/CG REPEATER 5

173.8125, CSQ     168.4750, CSQ     NI/CG REPEATER 6

South Florida FPS Changes

In addition to the upgrades to the Customs and Border Protection (CBP) radio network in Florida, it appears that the Federal Protective Service (FPS) has also upgraded to P25 digital.

410.8 MHz, N201 is now being used by the FPS in the Miami area. The same frequency is most likely used through out this FPS region. Some sites may have different NAC's.

You can read more about the CBP upgrades and frequency changes in the latest edition of The Spectrum Monitor, http://www.thespectrummonitor.com/index.aspx

CDC Frequencies

Some questions regarding the use of radios by the Centers For Disease Control and Prevention (CDC) have been posted in regards to the confirmation of Ebola in the Dallas, Texas area.

I know that the CDC uses federal UHF trunking at their fixed facilities around the Atlanta area. But a while back I posted possible CDC field use frequencies that might have been in use for the Swine Flu outbreak:

Email Apologies To All

To anyone and everyone who might have been sending me emails to the chrisparris@thefedfiles.com address - I realized that I have not been seeing any emails from that address for a while and just assumed no one was sending me anything. But a Fed Files fan on Twitter asked about an email he sent that I hadn't seen on any of my computers or email devices. I discovered that my emails were just sitting there and I wasn't seeing them. I've been trying to catch up on these as I can. 

Please continue to use this email address for future communications: chrisparris@thefedfiles.com
