It appears that the Federal Bureau of Prisons, part of the Justice Department, is continuing to upgrade their existing Motorola Type II trunked systems to APCO P-25 digital systems.
The Federal Correctional Institution (FCI) in Englewood, Colorado has recently moved to a P25 system, and here is the PRO96COM analysis of that system:

USAF Trunked System Expands in Colorado
It appears that the US Air Force is expanding their regional trunked radio system and will have Buckley Air Force Base moving off of the federally managed Front Range system.
The discussion of the recent changes can be found here:
http://forums.radioreference.com/colorado-radio-discussion-forum/317446-new-air-force-trunked-site-south-denver-metro.html
Indications from local listeners show that Buckley AFB will join Peterson AFB, Cheyenne Mountain and the Air Force Academy as part of a VHF/UHF, multi-state P-25 trunked radio system. You can see the system details here:
http://www.radioreference.com/apps/db/?sid=3593
For many years Buckley AFB was a subscriber to a UHF trunking system managed by the Federal Protective Service and shared with federal and military users. It appears that the military is consolidating their activity on their own radio system.
We will have to see what becomes of the UHF trunked sites that served Buckley to see if they are re-purposed for federal use or retired.

"New" trunked system in Southern California
On a recent trip the Los Angeles area, I stumbled upon a P-25 trunking control channel on 411.4500 MHz. I was located just south of the LAX airport in the Manhattan Beach area.
Using PRO96COM, I discovered that this trunked system was showing three frequencies, 411.4500, 412.4500 and 413.4500 MHz. The system showed a System ID of 001, Site 101 and WACN of 00001. The site status showed that it was in site trunking, and not networked to any other sites.
All of these seem to point to a site or system that was under test. While I monitored this control channel, there were no radio affiliations or other activity.
I have not seen activity on these frequencies in my past visits, but hopefully some of the folks living in the area can keep an ear on this and see what develops.

Portland Rose Festival Fleet Week 2015
I'm usually out of town for most of the annual Rose Festival Fleet Week, but I just made it back to get a chance to watch some of the US Navy ships that were docked in Portland depart the area this morning.
When heading across the river on Sunday evening, I was searching the 390-400 MHz band for any possible shipboard trunking systems, I came across an EDACS control channel on 397.6 MHz. This was coming from the USS Chosin, CG-65. I decided to try and come back to the area for the ships departure on Monday morning and see if I could figure out the trunked system setup.
Came back early on Monday morning before the bridge lifts to let the ships head out to the Columbia River screwed up traffic too much, I found a good parking spot where I could see and hear the ships. I noticed right away that these shipboard trunked systems are not designed to carry very far, so even with the ship in sight, the signal strength from theses systems was pretty weak, but readable. I also discovered a second EDACS control channel belonging to the USS Cape St. George, CG-71.
I monitored and searched the bands for a couple of hours as both the Chosin and the St. George departed and think I figured out the two Hydra systems. I was unable to fully confirm the system for the Chosin, so this is a best guess, but was able to scan and track the system for the St. George before she left port.

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.

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

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

CBP Florida Makes The P25 Switch
Over the last couple of years I have heard that the CBP was coordinating and installing new P25 digital gear in the state of Florida.
I just spotted a post on Radio Reference that indicates the Customs and Border Protection radio systems in Florida have finally moved towards the digital domain after being analog for many years:
http://forums.radioreference.com/federal-monitoring-forum/297786-news-flash-florida-bp-throws-p25-switch.html
There are what appear to be some of the new CBP DNET channels in the +170 MHz end of the band, so I will list them as they can be ID'd in the CBP Frequency Update area on the blog main page.

Air Force One Phone Systems
An interesting post has appeared on line about the new phone systems in use aboard Air Force One. It's an interesting read:

There is also an story on something I've always wondered about, how they got a secured Blackberry for President Obama:

NIFC NATIONAL AIR-TO-GROUND FREQUENCIES
The National Interagency Fire Center maintains a standard issue of nationwide air-to-ground (A/G) channels for use in firefighting and other incidents on federal lands. I have been asked for some time if I had the complete list of these A/G channels, so I decided to sit down and go through all the materials I had access to and see if I could come up with a good list.
What I discovered is that there are some variations of these A/G frequencies, and even some official US government publications don't agree. So keep in mind that this list is not cast in stone, but may have some variations...
