The TSA has decided to halt the expansion of the Screening Partnership Program, which allowed airports to choose private security screeners in place of the TSA screeners:
http://www.cnn.com/2011/TRAVEL/01/29/tsa.private/index.html?hpt=T2
There are currently 16 US airports that have opted out of using TSA security screeners. They are:
• San Francisco International Airport (KSFO)
• Kansas City International Airport (KMCI)
• Greater Rochester International Airport (KROC)
• Sioux Falls Regional Airport (KFSD)
• Jackson Hole Airport (KJAC)
• Tupelo Regional Airport (KTUP)
• Key West International Airport (KEYW)
• Charles M. Schultz-Sonoma County Airport (KSTS)
• Roswell Industrial Air Center (KROW)
• Frank Wiley Field (KMLS)
• Sidney Richland Regional (KSDY)
• Dawson Community (KGDV)
• L.M. Clayton (KOLF)
• Wokal Field (KGGW)
• Havre City County (KHVR)
• Lewiston Municipal (KLWS)
The March edition of Monitoring Times Fed Files column will contain additional details of the TSA communications.

Super Bowl XLV Update
Haven't had much time to update the blog, but things are starting to get busy here in Arlington. Some radio systems checks have been heard, as well as some military units checking communications.Things will be getting busier as the big game day approaches. Hopefully I will have some time to play with the scanners!

US Forest Service Radio Purchase
The US Department of Agriculture / US Forest Service has purchased a large number of P25 radios from RELM Wireless Corp:

As I have mentioned in some of the recent Fed Files columns, the US Forest Service has began to upgrade system infrastructure in US Forests near me for P25 operation. Some USFS systems in other areas have been operating in P-25 digital already.

Super Bowl XLV
Things are starting to ramp up for federal activity related to Super Bowl XLV in Arlington, Texas this February. There were rumors of the possible installation of some sites of the federal IWN (Integrated Wireless Network) in the Dallas Metroplex prior to Super Bowl. However it appears that money and time issues got the best of the proposal.
170.6250 MHz, N167 and 170.9375 MHz, N167 have both been noted as "new" frequencies for the area. They very well may be additions to the are for the Super Bowl, but will remain in place after the big game is over. Also, there have been reports of activity on 171.4375 MHz, a nationwide federal interoperability channel. 170.6625 MHz, N167 had been noted before the new year in Dallas, also a new channel for the area.
I will try to provide updates prior to the big game, and a complete wrap-up will appear in the May 2011 Fed Files column in Monitoring Times magazine.
DEA Updates
Some additional information has surfaced about the new UHF federal frequencies used by the Drug Enforcement Administration (DEA). As we have previously reported in the Fed Files blog, the DEA will be re-channeling their UHF frequencies and have started using these new frequencies in Texas and other southern US areas.
The frequency of 409.8250 MHz, N156 has been heard from the Houston area, but reports were that it is most likely a repeater in the outlying areas and not in Houston. 409.9000 MHz, N156 has been confirmed as a repeater, referred to as "Channel 9" on the west side of Houston.
Also, New Orleans now has a new P-25 DEA repeater on 409.6250 MHz, N156. This is the first confirmation of the new DEA channels being used outside of Texas.

Happy New Year!
Happy New Year from the Fed Files! Once again I was working at Times Square in New York City on New Years Eve helping broadcast the event. I had some time to scan and got a few hits on federal frequencies. Some were most likely normal New York City area frequencies, but a few were new. Here is a quick look at what I was able to log. Most of the communications were encrypted, but a few bits and pieces were in the clear. Quite a few radio checks were heard on the 167.7875 MHz Federal Interoperability repeater.
162.0250 MHz
162.3375 MHz
162.7375 MHz, N167
164.4000 MHz, N001 - USSS PAPA
164.7750 MHz, N167*
165.2375 MHz, N310 - CBP
165.9250 MHz, N167* Used at All Star Game simplex
167.4625 MHz, N207
167.7875 MHz, N652 - NYC Federal Interop VHF
167.7875 MHz, N94C
168.2250 MHz, N167 - NYC FBI G1/G2
168.3000 MHz, N167 - NYC FBI H3/H4
168.8250 MHz, N167 - NYC FBI H1
169.7250 MHz, N864*
170.3750 MHz, N167*
170.4250 MHz, N167 - FBI G3/G4
170.6250 MHz, N167
170.6250 MHz, N730
170.9000 MHz, N167
171.1750 MHz, N653 - Perhaps the input to 167.7875 MHz repeater?
171.2000 MHz, N293
171.5500 MHz, N167*
171.6875 MHz, N9C5 - DHS ICE Network
171.7250 MHz, N159
172.6625 MHz, N615
173.6625 MHz, N167 - NYC FBI A1
The frequencies noted with an asterisk were heard last year in Times Square as well. I'm not sure if these are normal NYC area FBI frequencies or not. Perhaps some local listeners can confirm these. But things were definitely hopping this New Years.

Another New DEA P-25 Frequency Found
Listeners in the Houston, Texas region have reported finding another active P-25 frequency that is most likely a new DEA channel.
410.4125 MHz, N156 has been heard active and at this time is presumed to be a repeater in the downtown Houston area. All comms so far on this channel have been reported as being encrypted.
This appears to be part of the move by the DEA to follow the new 9 MHz repeater offset in the federal UHF band. In theory, the input frequency to this repeater should be 419.4125 MHz, but that has not been confirmed yet.
I also forgot to post a previously heard simplex channel, 414.4500 MHz, N156. Also being reported in the Houston area.
Not sure why Houston seems to be the area chosen for the rollout of the new P-25 frequencies, while most of the rest of the country appears to still using the standard UHF channels.

DC Area IWN Rollout Without DHS
An interesting article has appeared on line talking about the roll out of the new IWN DC area overlay trunked system:
http://psc.apcointl.org/2010/11/29/agencies-in-d-c-area-will-be-able-to-communicate-on-radio-system/
As I posted back in September, the new VHF IWN trunked sites started to appear recently in the Washington DC area, and will serve various subscriber agencies, primarily the Department of Justice. However, the article linked above indicates that the Department of Homeland Security (DHS) will not be participating in the DC area system.
Some DHS agencies are participating in the original IWN sites in the Pacific Northwest, with CBP Customs and Border Patrol being heavy IWN users along the US-Canada border areas.

LA USSS Back On The Air
On Monday, November 30th, while waiting for a flight at LAX airport, I had time for some scanning. While searching the federal bands I happened to catch some radio techs doing checks on the Los Angeles area US Secret Service radio sites. This comes after one of the sites serving the LA Metro area was destroyed by wildfires in August, 2009.
I caught some clear radio checks on:
165.2125 MHz, N001 - MIKE
165.3750 MHz, N001 - CHARLIE
165.7875 MHz, N001 - BAKER
171,7625 MHz, N001 - Input to BAKER repeater on Mt. Disappointment
I missed the radio checks, but other listeners reported:
164.4000 MHz, N001 - PAPA
164.6500 MHz, N001 - TANGO
164.8875 MHz, N001 - OSCAR
When they were finished, one technician proclaimed that they were "finally back on the air after a year and a half!"

New Border Patrol in Arizona
In the November issue of Monitoring Times, I mentioned a number of VHF P-25 repeaters that had been heard on the air in Southern Arizona over the past summer. It now appears that even more new frequencies are on the air and are being used extensively by CBP Border Patrol.
Since my last visit to the Tucson area last spring, there has definitely been an increase in activity on these new frequencies, but the traditional Border Patrol channels in the 163 and 168 Mhz range have become used less and less. If you live in the Southern Arizona area, start searching for new frequencies. Here is a list of what is being heard now:
163.6250 MHz, N206
163.7000 MHz, N201
166.7375 MHz, N30E
168.8250 MHz, N302 - RED MOUNTAIN
168.8250 MHz, N330 - WIDE AREA
168.8250 MHz, N710 - WIDE AREA
169.1625 MHz, N293 - CBP AIR 4 (More on this frequency in the January Fed Files!)
169.5500 MHz, N203 - TUBAC AREA BORDER PATROL ON 1-19
169.9375 MHz, N330
169.9375 MHz, N653 - GILIO 1

173.6500 MHz, N206
173.7375 MHz, N130
173.9375 MHz, N304
This appears to be a major move towards a new network of Border Patrol and CBP operational repeaters that may continue across the southern United States, and along the lines of what has been in use along the Southern California region for quite some time.

FPS Chnges & Updates Continue
UPDATE - Reports from the Northeast US are that many cites in FPS Region 1 (New England) have switched over to 408.2000 MHz repeaters from 417.2000 MHz. It also appears the region is now using a P-25 NAC of N201. Some stragglers may still be using 417.2000 MHz, but should change soon. These moves are to update the repeater frequencies to a new standard 9 MHz offset, meaning the repeater inputs should now be 9 MHz from the repeater output.
Besides the primary region-wide repeaters, be on the lookout for simplex or stand-alone repeaters that might be in use in some specialized federal properties.
Despite some areas of the country already using new frequencies and P-25 digital radio, some areas of the Federal Protective Service are still awaiting updates to the communications systems. Here is a recent request for bids on replacing and upgrading radio gear for FPS Region 7, which includes sites in Texas, Louisiana, Arkansas, Oklahoma, and New Mexico.

414.5625 MHz
Over a year ago, while in the Houston, Texas area, I stumbled across some encrypted P-25 traffic on 414.5625 MHz, NAC 168. The traffic was simplex and have found no confirmed data on what agency might be using that frequency.
Recently another listener in the Houston area has reported hearing activity on that same frequency, also encrypted, so whoever it is, they are still in business.
However, now I have received a report from the Charlotte, North Carolina area of the same frequency and and NAC being used there. Again, always encrypted, so no agency identification has been determined yet.
Keep this one in your scan list and see if it is active near you!

World Series Game 2
Things settled down a bit in our part of the broadcasting compound for the second game of the 2010 World Series. so I had some time to listen to the scanner more. Here is what was busy during the game:
157.1750 MHz - Marine channel 83A with Coast Guard units patrolling the waters outside the ball park. Call signs heard were MARINE 1, MARINE 2, PIKE and PIKE 2
162.3500 MHz - Weak P-25 or analog with DES. No confirmation of what it was.
163.6125 MHz, 127.3 pl - Speaker Palosi Capitol Police security detail at the game again.
166.4625 MHz, 100.0 pl - Unknown agency operating outside the ballpark. Somewhat informal conversations. Frequency is known as DHS Common or Treasury Common, but is found in most federal law enforcement channel plans.
170.7500 MHz, N293 - Unknown agency, encrypted full time
170.9250 MHz, N167 - FBI units, probably on location at the game. During game 1, heard some units in the clear and confirmed they were in the stadium. Game 2 and everyone was secure, but signal strength seemed to indicate they were still on location and simplex.
Other frequencies were heard as well, but probably did not have anything to do with the World Series:

New TSA P-25 Frequency at BOS
I know the blog postings seem to be stuck in TSA mode these days, but I post 'em as they come in to me...
I've received confirmation of a new TSA P-25 digital channel in use at Boston Logan Airport, BOS. The frequency is 166.2875 MHz, N001, simplex. They seem to be using this frequency to coordinate passengers going throught the millimeter-wave X-ray machine, also known as the full-body scanner.
This is a new frequency for the TSA channel line up, joining a whole bunch of new frequencies that have turned up with the new Icom radios.

More TSA Radio News
Here are a couple of news items regarding TSA and their radio communications.
This item has some details about the purchase of the Icom F-50V radios as part of the efforts to equip everyone at the airport security checkpoints with radios. The article indicates that the original purchase was for 10,000 radios:

Secondly, this item describes how the TSA is interested in adding OTAR (Over-The-Air Re-keying) of their existing radios:

If you download some of the linked documents in this page, it describes the test procedures that indicate the OTAR encryption keys will be provided by the Customs & Border Protection (CBP) Key Management Facility.
One could speculate on why the TSA needs to have OTAR. Almost none of the P-25 radios used by the TSA are using encryption, although they are all capable. Some airport locations are using encrypted communications full-time, but many are not. This request, along with a request from TSA for RF tracking devices, seem to indicate a more aggressive technical requirement that just airport security checkpoints.
This item has some details about the purchase of the Icom F-50V radios as part of the efforts to equip everyone at the airport security checkpoints with radios. The article indicates that the original purchase was for 10,000 radios:

More "New" TSA Analog Frequencies
Since the addition of the Icom F-50V radios to the TSA security checkpoints at US airports, some new frequencies have started showing up. These new frequencies are not part of the original TSA channel plan that is in all of the P-25 radios the TSA is using.
Recently I found two additional frequencies in use. First, at San Francisco International airport (SFO), I found the contract TSA look-alikes there using the FT-50V radios on 162.2750 MHz, 131.8pl with voice inversion. On another recent trip I found the TSA at Los Angeles International airport (LAX) in Terminal 3 using 166.7875 MHz, 123.0 pl, also with voice inversion.
Anyone got any additional TSA channels we haven't posted yet? Pass them along to us at Monitoring Times!

170.3375 MHz in Dallas - TSA?
I have received some reports of a new P-25 digital channel being heard in the Dallas/Ft. Worth Metroplex.
Reports are that 170.3375 MHz, NAC001 has been heard with clear traffic that seems to make references to possible TSA operations at DFW Airport in Grapevine.
This frequency does not appear in the previously known TSA frequency assignments, however, DFW Airport had always had some non-standard TSA radio operations. 169.1625 MHz and 169.1875 MHz have previously reported as being used but the TSA at DFW. Apparently they were concerned about TSA frequencies used at Dallas Love Field would interfere with operations at DFW.
