These flights will be using NNSA helicopters equipped with sensors designed to monitor normal background levels of radiation. The NNSA’s Remote Sensing Laboratory (RSL) out of Joint Base Andrews will be performing the assessment for local law enforcement of D.C. area.
As far as active frequencies, the NNSA has assignments all over the federal spectrum, so searching might reveal something new. However, I'm not sure how much radio chatter there will be during these flights. You might catch the helicopter on some of the VHF low-altitude VFR aircraft frequencies, possibly using the ENERGY call sign.

There is all manor of speculation over what this is. It is clearly a P25 signal, probably a control channel for a P25 trunking system, but the radio is not displaying the System ID or Site. This is not uncommon on federal P25 trunked sites, as they sometimes utilize a message format that scanners cannot display properly. The trunking information is still viewable with a program like Unitrunker or PRO96COM.
406.9125 MHz is the only site information available, and it's showing a P25 NAC of N005. One posted on the thread seems to indicate that it comes in full strength north and east of Nashville. One suggestion is the Old Hickory dam, but I'm not sure the Army Corps of Engineers would be running a UHF P25 trunked system. Others have suggested a federal prison facility, but there really aren't any near Nashville.
Further information reveals that this is most likely part of a new P-25 UHF trunked system being built out for the Tennessee Valley Authority (TVA). The control channel mentioned above reveals the following:
System ID = 372
WACN = 00001
Site = 505
Reports are that Harris is building this new system throughout the TVA area of responsibility.

The FPS had been active on 417.2000 MHz in the Los Angeles area for some time, but recently the frequency went silent. They have moved to 410.8000 MHz, 127.3 PL, part of the reorganization of the federal 406-420 MHz band. They still have not moved to P-25 digital as of this week, when I heard them on the new frequency. Other cities in the Southern California area are reported to be using 406. 2000 MHz, also in analog. The inputs to these new repeater frequencies are +9 MHz, part of this new organization of the UHF band.
In the Pacific Northwest, the FPS has long been active on 408.2000 MHz, in P25 digital and not encrypted. At some point last week, nearly all the transmissions in the Portland, OR area on the FPS primary frequency have been encrypted. An occasional unit will transmit in the clear, but the response from the FPS MegaCenter dispatcher is encrypted.
Word was out that encryption was coming for some time. Some mobile units were occasionaly using encryption, but the dispatchers would usually respond in the clear. Some areas of the country have had encryption on the FPS channels since the switch over to new frequencies or P25 digital. But some areas remain in the clear.

On the way into Atlantic City, I did catch some traffic from FEMA on 407.6625 MHz, N421. And as with the FEMA communications I heard in New York City, some were in the clear.
Once in the city, I came across several trucks with federal government license plates that were apparently with the Western Area Power Administration (WAPA). In addition to the WAPA vehicles, there were some additional power service trucks that were contractors working to restore power. All the vehicles carried VHF-hi band antennas, but I was never able to catch any radio transmissions from them.
But things must be getting back to normal, as both the FBI and the DEA were busy in the area during my time on the boardwalk!

The original poster did not list any system information, other than it is reporting as Site 002. The control channel frequencies he was hearing were 408.7125 & 410.1125 MHz. He also reported a voice channel of 408.2250 MHz. My suspicion is that this is an additional site to the already existing Oak Ridge DoE NNSA P25 trunked system:
If anyone has any additional information you want to pass along, please do!

I have been monitoring mostly from the Ft. Wadsworth area on Staten Island. Ft. Wadsworth is the location of the US Coast Guard Sector New York. They have had numerous fly overs by USCG helicopters and have been landing some at the baseball field on Ft. Wadsworth. I've also been seeing many other military and other helicopters flying over the area over the Verrazano-Narrows Bridge.
The National Guard and active duty military units have begun to arrive and are staging at various locations, one of which is Floyd Bennett Field in Brooklyn. I have not been able to confirm any military or National Guard communications yet, but the National Parks Police are very busy supporting operations in their areas.
Here is what has been busy:
|162.3250||N293||USCG NET 111|
|USCG NET 115
|165.2375||N301||DHS CBP DNET 1|
|166.0500||100.0||FORT WADSWORTH NPS OPERATIONS/SECURITY|
|166.3250||136.5||US PARK POLICE - NEW YORK AREA F1|
|169.8250||N225||NATIONAL PARK SERVICE, GATEWAY NATIONAL RECREATION AREA|
|345.0000||AM||USCG AIR OPERATIONS|
|406.3375||N482||USPS POSTAL INSPECTORS|
|408.2000||N270||FEDERAL PROTECTIVE SERVICE|
During the evening I heard multiple communications on 123.1 MHz from "AVIATION BASE". They were apparently directing inbound helicopters to landing and parking areas somewhere. There was mention of parking on a baseball field near a flight line. I thought it might have been at the old airfield at Floyd Bennett, but haven't been able to confirm that. Reports on Radio Reference have 242.2 MHz and 283.0 MHz being used by the National Guard helicopters operating in the area.
And I forgot to include in the list above the Red Cross frequency of 47.42 MHz, which I caught some transmissions Saturday.

I have no idea who this might be and why they are using this frequency. This frequency is part of the federal interoperability pool of channels set aside for federal/local communications. This particular frequency is known as "LE-2", if a repeater, or "LE-6" if simplex.
This frequency is part of the federal interoperability channel plan found in the DHS National Interoperability Field Operations Guide (NIFOG), which can be found here: http://www.dhs.gov/national-interoperability-field-operations-guide

After IWN's cancellation, DOJ continues to push for radio modernization - FierceGovernmentIT
Contained in the body of the article is a link to a PDF file that was obtained from the Justice Department with some related (and some redacted) information on the future of DoJ communications.

A similar setup has appeared at other large Presidential events, including political conventions and such. No indication as to who it belongs to, but the trailer itself appears military. I suspect the White House Communications Agency (WHCA) is probably involved.

"What LightSquared wants to do is take one 5MHz band that it already uses for its satellite service (at 1670-1675MHz) and combine that with the next band up (1675-1680MHz), which is used for federal purposes including National Oceanographic and Atmospheric Administration weather balloons."

An AP story on the discovery of more drug cartel radio towers in Mexico:
Rumor had it that the cartels were being supplied by radio communications dealers in Texas, but I haven't found any information to support that yet.
Another interesting and more detailed story about this has appeared here:

I'm in New York City and noted a marked increase in radio traffic on known Secret Service and Department of State Diplomatic Security channels this weekend. It is most likely due to the arrival of Iranian president Mahmoud Ahmadinejad, here to speak at the United Nations. Unknown if this radio traffic is related to any other VIPs in for this event. If you in the area, search the VHF & UHF bands and see what pops up...
I now see that the UN General Assembly is gathering this week, as well as the "Global Initiative" with the Clintons happening today. So a true monitoring extraviganza in New York City this week!

I have updated the DEA frequency page, which you can find at the top of the Fed Files blog home page.

Sometime over the last month of so, they seemed to have moved off of the IWN for their main operations and have gone back to 172.1500 MHz, N001 and 172.9000 MHz, N001, (The Icom analog radios have always been on 169.3000 and 172.1500 with voice inversion). 172.9000 is set up as a wide area repeater that covers the Portland metro area. I have heard some encrypted traffic on this repeater, as well as clear traffic that seems to be supervisors at PDX airport.
Why this move has taken place is unknown. Perhaps the TSA was being billed for the use of the system and it was eating up more system capacity than they expect.
More information as it becomes available.
For the latest US Coast Guard channels, check the frequency page at the top of the Fed Files Blog home page.

The Democratic National Convention begins today in Charlotte, NC.
Some reports of convention related communications are filtering in. Many are posting on Radio Reference, but reports are mostly of convention traffic on the local and state 800 MHz trunked systems.
Got any interesting federal frequencies related to the DNC? Send them along to the Fed Files!
News outlets are now reporting the Secret Service code name for GOP VP candidate Paul Ryan. The code name for Ryan is reported as "Bowhunter" and his wife Janna Ryan is reported as "Buttercup". The reports apparently originated with GQ Magazine.
As reported previously, Mitt Romney has the code name of "Javelin".

Previously the Atwater facility was using a Motorola Type II trunked radio system:
The new radio system is now a pure P-25 digital system:
System ID: 4C7

As the powers that be mull a possible delay in the start of the 2012 Republican National Convention in Tampa, due to Hurricane Isaac, some frequencies have been reported as active.
Secret Service and Coast Guard channels have been reported as active with both encrypted and clear communications.
I will not be in attendance this year, so hopefully some local monitors can pass along some active federal frequencies. And interesting updates will be posted here.
I know it's a little late (but I tend to wait for these events to be over before posting), but here are a few active federal channels that were submitted by anonymous listeners in the Tampa area;

Both the CBP and Antenna Authority are apparently reluctant to reveal exactly what the contacted antennas are to be used for, (see photo below).

As some may be aware, the US Navy is installing sites for the Enterprise Land Mobile Radio System (ELMRS) trunked radio network at bases across the country and around the world. These P-25 trunked sites can be found in the 380-400 MHz band of DoD controlled radio spectrum. And until now, all the sites of the ELMRS system were in that band.
But apparently now that both NSAC and the Charleston Air Force Base are now one base, called Joint Base Charleston, they made the CAFB 400 MHz trunking system a site on the ELMRS system. This is the first time I have run into a site on the ELMRS system that is NOT in the 380 MHz band. Both sites are using the same System ID of 14C, and both using a P-25 NAC of N140. Neither site shows the other as a neighbor, or any neighbors for that matter, so not sure if any roaming takes place between the two.
Here is what I found active:
And here is the Charleston Air Force Base site:

The system consists of both 800 MHz and VHF trunked sites to provide statewide coverage. What is interesting is that the state has taken not only FCC controlled spectrum, but has a number of channels from the federal spectrum as well. My guess is that since VHF public safety allocations are getting difficult to find, they were able to get some VHF federal channels as a cooperative effort with the feds.
There were indications that the next deployment of the now unfunded, federal IWN trunked system would be in the Midwest. So it seems that giving the frequencies over the state of Missouri and letting them build the radio system (probably with federal grants), then getting federal agency access to the system is another method of getting what the Justice Department wanted in the first place.
Also, I have noticed a similar situation with the Nebraska state VHF trunked radio system, called the N-WIN: http://www.radioreference.com/apps/db/?sid=6699 .
The WYOLINK system in Wyoming has only one site in Cheyenne that is using federal VHF channels, and I assumed that was for interoperability with the F.E. Warren AFB there:
The Montana Statewide Interoperable Public Safety Radio System (MSIPSRS?), a VHF P-25 trunked system, features only 1 site (so far) that is using a single federal allocation - Site 44:
UPDATE 1 -
I was advised that the new State of Maine VHF P-25 trunked radio system is planned to utilized frequencies in the federal VHF band. The system is not yet built out, but planners are acquiring VHF frequencies from as many sources as they can.
Also, the State of Wisconsin is utilizing some VHF allocations in the 138 - 150 MHz bands that were given over in a cooperative agreement with the Department of Defense.

First, I received a report of DEA activity in the Boston area using 413.9750 MHz as an input to a 419.4250 MHz repeater. Both frequencies were using a NAC of N156. This would not only be reversed from other reports of a repeater on the 413 frequency with an input of 419, but it does not conform to the federal 9 MHz repeater offset.
Secondly, I was able to confirm that the DEA in El Paso, Texas is using 409.8250, 409.9500 and 410.8125 MHz, all with a NAC of N156. The 410.8125 MHz frequency had not been reported before.
Here then is my current list of "new" P-25 digital DEA channels in use in some areas of the country:
409.6250 MHz, N156 - Repeater, Possible F1
409.6750 MHz, N156 - Repeater, Possible F6
409.8125 MHz, N156 - Repeater, Possible F7
409.8250 MHz, N156 - Repeater, Possible F8
409.9000 MHz, N156 - Repeater, Possible F9
409.9500 MHz, N156 - Repeater, Possible F10
410.4125 MHz, N156 - Repeater/simplex, Possible F11
410.8125 MHz, N156 - Repeater
411.1250 MHz, N156 - Simplex (SPLX 1)
411.1500 MHz, N156 - Repeater/simplex?
412.2000 MHz, N156 - Simplex (SPLX 2?)
412.5250 MHz, N156 - Simplex
413.9750 MHz, N156 - Repeater/Simplex (SPLX 3)
414.2000 MHz, N156 - Simplex (SPLX 4)
414.4500 MHz, N156 - Simplex (SPLX 5)
418.3250 MHz, N156 - Simplex or possible input to 409.3250 repeater (not heard)
418.6250 MHz, N156 - Input to 409.6250 repeater
418.6750 MHz, N156 - Input to 409.6750 repeater
418.8125 MHz, N156 - Input to 409.8125 repeater
