NASA JSC Shooting

News reports indicate a suspect fired two gun shots then barricaded himself in Building 44 at the Johnson Space Center campus in Houston, Texas. As of the time of this blog entry, the situation was still unfolding.

For those wondering about monitoring the situation at JSC, the best bet would be listening to the Houston police conventional UHF frequencies for any activity. The Johnson Space Center does have a UHF federal trunked system for all of it's radio communications, but at last check all the radios were using P-25 digital mode with encryption enabled full time.

For future reference:

VAMC Pittsburgh Radio Updates

I've received some information about changes to the Pittsburgh VA Medical Center radio frequencies. It appears that they are in the process of moving frequencies around and are actually simulcasting on old and new frequencies at the same time.

Here's what is reported as active these days:

171.0125 - PL 103.5 - Transports

173.9375 - PL 103.5 - Transports

172.6875 - P25 - Police

New Low Profile Federal Radios

A few years ago I saw this request for information from the Department of Homeland Security regarding a "low profile", cell-phone look-alike radio:

http://www.cbd-net.com/index.php/search/show/575529

A recent posting on the "Batlabs" board indicates that Motorola has come out with just what DHS wanted, and they are calling it the XTS4000:

http://batboard.batlabs.com/viewtopic.php?p=313386&sid=1896dc86ad52bb7b6e99d3773ecc31f2

While there is some speculation that these were developed with the IWN trunked system in mind (since they will do P-25 VHF trunking), I would guess that any federal agency using VHF systems would be interested in a radio like this. This model covers VHF frequencies, but could a UHF version be in the works?

Some additional information on the radio can be found at these links to the FCC web site:

IWN Redux - It's Growing Again! UPDATED!

Reports are being posted on RadioReference.com that a new IWN site has shown up in the Sault Ste. Marie, Michigan area. It is broadcasting a P-25 control channel on 167.8125 MHz and is showing the IWN System ID of 715 with a tower number of 12015 (looks like they are expecting a lot of tower sites!). Here are some additional site frequencies as recently posted on RadioReference:

167.8125 - Primary Control Channel
167.9375 - Voice
168.1875 - Alternate Control Channel
170.9375 - Voice

This comes despite information in the recently released OIG report about the IWN Project. In that report it was stated that the next phase of the IWN deployment would be in the Southwest US:

http://www.usdoj.gov/oig/reports/OBD/a0725/final.pdf

The IWN has recently grown from the initial "testbed" system in Western Washington State down in to Northern Oregon and is expected to continue to grow as the project continues. Listeners in the Northeren Michigan area should keep an ear out for additional control channels and voice channels that go with them!

Los Angeles BoP MDC

For a while I have been seeking information on the Los Angeles Metropolitan Detention Center, operated by the US Bureau of Prisons. I just stumbled on several P-25 voice channels and a Motorola trunked control channel that I think may be located at the LA MDC in downtown Los Angeles.

I think I have picked up this control channel on my last visit to LA, but the frequency is also used by the Camp Pendelton UHF trunked system, and I may have ignored it.

Still working on more system information but here is what I have so far:

Motorola Type II

System ID - ca0b

406.8125 - P25 voice

409.4125 - P25 voice

409.9500 - Control channel

Fed Files Contest Winner!

Congratulations to David Stearns of Overland Park, Kansas. He won the drawing for an original copy of Monitoring Times, volume 1, #4. That issue of MT featured a front page story about the NTIA classifying the federal frequency Master File.

Thanks to everyone who entered the Fed Files drawing. We'll do it again when we come up with another prize!

CBP Border Patrol Update

After my recent trip to Arizona, I decided to dust off my listings for the DHS Customs & Border Protection Border Patrol. The Border Patrol continues to use its legacy VHF frequencies that are in blocks assigned to the Justice Department.

Currently the CBP Border Patrol doesn’t have a national channel plan like some agencies, but assigns their frequencies as needed locally. Along both the northern and southern border areas (except for southern California), the 163 MHz frequencies are the “backbone” repeaters with multiple input frequencies, from the 162 MHz, 165 MHz and 168 MHz blocks of frequencies. These frequencies can be used as repeaters or “local” simplex frequencies as well.

In areas not near the US borders, the former US Immigration agents, now part of DHS as the Immigration and Customs Enforcement may use frequencies from these blocks for local use.

Justice IWN Update - The Next Move?

As I have been reporting both on the Fed Files blog and in the Fed Files column in Monitoring Times, the Justice Integrated Wireless Network or IWN continues to grow and progress towards it's goal of being a nationwide digital trunked system for federal agencies. However, a recent audit of the systems shows there are some troubles for the IWN Project:

http://www.usdoj.gov/oig/reports/OBD/a0725/final.pdf

The above link contains some interesting information about the project and its use by various agencies so far.

The IWN expanded it's coverage from Washington State down in to Oregon and the Portland metro area in late 2006. It now appears to be in full use by Portland area federal agencies. We've been monitoring a LOT of activity on the system in the last month or so, almost 24/7. Several talk-groups on the system are showing the majority of the activity, but since the radios have been set up with the encryption selected automaticaly, I haven't heard any clear transmissions since the radio techs finished with their installation tests. But remember - systems are not encrypted, talk groups are not encrypted, but it is the individual radios that are encrypted.

So where will the IWN show up next? Information in the above referenced audit report confirms that the southwest US is the next region to start the build out. I am currently in the Phoenix area (more on that in another blog entry) and have noted there is a P-25 control channel on 165.6375 MHz. It is part of the Phoenix area P-25 trunked system that allows federal VHF users to tie directly in to the 800 MHz system without patches.

Here is some budget information for the IWN project:

http://www.dhs.gov/xlibrary/assets/mgmt/e300-dhs-iwn2008.pdf

So keep a lookout for P-25 control channels showing up in the VHF federal band in your area!

NOAA UHF Weather Links

Some listeners may not know that the NOAA has some UHF frequencies that are used for "links" between the NOAA Weather Offices and the VHF weather transmitters that are located across the country. Sometimes, depending on the location of the NOAA offices, you can hear the weather broadcasts better on the UHF link frequency. And if the VHF Weather transmitter is off the air for some reason, you still might be able to catch the feed on the UHF frequency!

Here are some UHF frequencies that are allocated for use by the NOAA:

410.1000 - Weather Link
410.1750
410.4750
410.5500
410.5750 - Weather Link
410.6750
410.7250
410.8500
410.8750
412.3250
415.8500
415.9000 - Weather Link
416.3750 - Weather Link
416.9750 - Weather Link

I have noted where I have heard the NOAA weather being linked to VHF transmitter sites.
So if you have trouble hearing the normal VHF NOAA Weather frequencies, give the UHF federal band a search!

National Marine Fisheries Service

I received some frequencies that are reported to be used by the National Marine Fisheries Service, a division of NOAA:

http://www.nmfs.noaa.gov/

These are reported as being used in hand-held radios. I haven't confirmed these personally, but hope someone can!

FBI Aircraft Call Signs

This past year we have seen reports of FBI aircraft operations using a new call sign. Previously the call sign of ROSS was used by aircraft being used in FBI operations. This call sign was used on the FAA air traffic control channels in order to identify them as a law enforcement aircraft to flight controllers. The ROSS call was followed by numbers, sometimes related to the aircraft FAA registration, or "N" number.

However, some have reported that the ROSS call has been replaced by the call sign JENNA. Some have reported the call pronounced with a long E, as "jean-ah", others have heard it as "gen-na", with a short E sound. Most recently JENNA 85 (N6317T) was heard landing at Paine Field in Everett, Washington.

I have also received reports that this new JENNA call sign is actually an addition to the ROSS call. The JENNA call is supposed to be used by non-FBI aircraft and non-FBI flight crews being used on FBI operations, where the ROSS call is still used for FBI owned aircraft with FBI flight crews.

As a possible related side note, I recently heard a "JENNA 01" on the ATC channels over Colorado or Utah. Where were they headed?

BTW, the original FAA document that had all the assigned federal aircraft call signs has been modified, and the table with the call signs has been eliminated;

http://www.faa.gov/ATPUBS/FSS/fss1401.htm

The document linked above used to have a table of assigned call signs for federal law enforcement and military aircraft for use while communicating with FAA air traffic control. I have a printed copy of the original document that contains the call sign table 14-1-51.

Anyone know anything more? Let us know at the Fed Files!

IAD BETWEEN FLIGHTS

I had a little time between flights at Dulles International Airport near Washington, DC this week. Here's a little of what I was able to scan from Terminal D:
162.3500 MHz - FAA, Wind Shear data?
165.8250 MHz, P-25 - "409 to Command Center..."
168.9250 MHz, P-25 - DHS Customs & Border Protection at IAD
171.2375 MHz - Paging data
172.9000 MHz, P-25 - TSA at IAD - The TSA seems to be encrypted most of the time here. Very unusual for TSA, but I've heard reports they are encrypted full time in San Diego also.
407.8625 MHz, P-25 - Close Call hit on this frequency, sounded like "SIDE DOOR" calling Patrol Units.
408.6000 MHz, P-25 - Another Close Call hit. Active, but unknown who it is.
409.7125 MHz, P-25 - Yet another Close Call hit. Also active and unknown.

Maybe some of the folks who regularly monitor the DC area can fill me in on who all the UHF P-25 frequencies belong to!

Coast Guard Covers DC

A recent post on the SCAN DC list pointed to this press release about the recent move from Customs and Border Protection to Coast Guard helicopter assets patroling the National Capitol District:

http://www.piersystem.com/go/doc/651/145886/

The Coast Guard is using HH65-C Dolphin helicopters to patrol the DC area and intercept wayward aircraft.

167.8625 MHz Anyone?

For over a year now I have been catching a lot of voice and digital paging data on 167.8625 MHz in different areas of the country. Despite this frequency falling in to the "normal" range used by the FBI, I am 99.9% sure that this is being used by the Department of Veterans Affairs for medical paging at VA Medical Centers across the country . I'm hoping some Fed Files readers can help confirm if this frequency is used in your area. So give this frequency listen and let us know if you catch some paging data or someone calling for a doctor to X-ray!

JIWN Update

I had a chance to gather some new frequency data for the Justice Integrated Wireless Network P-25 trunked system. This system has started to expand and is the model for more systems that will start appearing in other parts of the country.

I haven't been able to update my logs for all the system sites yet, but here is what I was able to update over the holidays:

Traffic on this system has been mostly encrypted, but I suspect when the interoperability features that will be linked to local public safety systems start showing up, more traffic may be in the clear.

Also, despite the availability of this system, most federal agency conventional channels continue to be used.

NYC Federal Interop Tests

I've received some information about weekly testing of the New York City federal interop radio channels. Reports are that 167.7875 MHz, 407.7750 MHz and 414.7500 MHz are all used in these weekly check-ins with various local, state and federal agencies. The input to the 167.7875 MHz P-25 repeater is believed to be 164.7375 MHz and 407.7750 MHz is most likely the input to the 414.750 MHz repeater. The control operator appears to be the FBI New York Communications Center. I also heard a story that even though 414.7500 MHz is a nationwide US Postal Inspectors frequency, two Postal Inspector units who were trying to use this repeater in New York City were chased off the air by the FBI communications operator. I wonder if they leave these frequencies patched all the time, or someone forgot to drop the patch after the interop test?

For more information on the participating agencies and the radio systems involved:

MT Reader Only Access

A new feature of the Monitoring Times website is a "Reader Only" access area. Look for a password in each issue of Monitoring Times for access to this area.
I have started uploading some Fed Files documents that you may find interesting, so check the Reader Only area for new files.
For more information, click the link to the MT web site:

SFO DHS Update

On a recent stopover at San Francisco International Airport (SFO), I was searching the federal bands and found that the DHS CBP/ICE repeater on 170.6250 MHz has as an input of 166.2500 MHz!

Anyone for NAC's?

I've been getting some requests from readers for information about the federal use of Network Access Codes or "NAC"s on P-25 digital channels. So far there are few ways for the monitoring hobby to actually read or use NAC's, but since CTCSS or PL tones are going away when radio channels turn digital, maybe a pattern of NAC assignments by particular agencies will reveal itself.

If you are able to decode NACs on federal P-25 systems, consider starting a federal NAC database here at the Fed Files!

DHS Releases National Interop Assessment

The Department of Homeland Security (DHS) today released scorecard assessments of interoperable communications capabilities in 75 urban and metropolitan areas nationwide. Interoperable communications involve policies, technology and training that enable law enforcement, fire and emergency medical services from multiple jurisdictions in a common community to effectively communicate within one hour of an incident.

Durango Dispatch USFS Info

A source passed along this link to the Durango Dispatch Center firefighting information packet. These PDF files occasionally show up on line sometimes, but then they can dissapear just as quickly:

http://www.fs.fed.us/r2/fire/drc/2006briefguide.pdf

The Durango Dispatch Center (DRC) is an interagency dispatch center responsible for incidents and resource mobilization coordination for the San Juan Public Lands (San Juan NF - USFS and San Juan Field Office -BLM), Ute Mountain Ute Reservation, Southern Ute Reservation, Mesa Verde National Park, Southwest Colorado counties, and Colorado State Forest Service.

Federal Air Marshals Communications

Recent posts on the AirCommSouthwest Yahoo group were concerning the Federal Air Marshals Service and an incident involving an Air Marshal on a recent flight. After the incident, in which a passenger was subdued by an Air Marshal, the FAM requested the pilot call in a report of what happened. The pilot was heard on an ARINC VHF air-to-ground frequency calling in the incident. Some wondered about what the Air Marshals have to communicate with while on duty.

Although there have been reports of some type of satellite or world-wide communications system, the Federal Air Marshals most likely just have cell phones. One list member posted a link to this document that mentioned the TSA and Federal Air Marshals Service using satellite communications:

http://www.house.gov/hasc/schedules/6-21-06CavossaTestimony.pdf

However, further searches on the subject of the Air Marshals Service and satellite communications reveals this story:

http://blogs.abcnews.com/theblotter/2006/06/air_marshals_bo.html

It seems that if they have a satellite communications system, it doesn't work as advertised.

I also received some anonymous information regarding the Federal Air Marshals and a UHF radio system that was installed for the New York Field Office:

F1 408.050 (418.050, input)

F2 418.075

F3 418.575

F4 418.400

It's not known if these are used nationwide or only in the NYC area.

Coast Guard MSST Activity

I recently received some loggings of some USCG MSST activity in the Southeast US...

From an anonymous source:

"Within the last year, I have had two opportunities to monitor what I believe is MSST 91108 (King's Bay). They have done security zone operations on the Savannah River at Georgia Ports in both March and December. On both occasions they have used 25' RB-S Defender Class boats using 2548# hull numbers. I can only make an educated guess that they are from King's Bay, but they are certainly an MSST, as they were addressed as such by the civilian police boats working on the river. They operated on 157.050, Ch. 21 with guard through Sector Charleston rather than Station Tybee. They ID'd variously by hull number, THUNDER ### (last 3 digits of hull number), and VENOM ### (last 3 digits of hull number). They used 157.075, Ch. 81 and 157.175, Ch. 83 for internal / boat-to-boat communications. They used hull number / THUNDER/VENOM callsigns here as well as COYOTE, SUNCOAST, and VOODOO (these last 3 I think may have been coxswain or crew related and not boat-assigned)."

Thanks to my anonymous source for passing that information along...

For those not familiar with the Marine Safety and Security Teams, you can read more about them here:

What's Up in MT?

The January Monitoring Times Fed Files covers a number of topics, including our Fed Files drawing for an original issue of Monitoring Times, and information regarding MT "Reader Only" access to areas of the MT web site. We also cover a number of federal agency frequencies, including the US Postal Inspectors, Immigration and Customs Enforcement and a close look at the Justice Department's "25 Cities Project". And we get a view of Oklahoma City federal scanning with the help of a Monitoring Times reader!

A Very Merry Fed Files Christmas!

Sorry for the lack of new blog entries these days, but between traveling for work and getting up to speed on the holidays, I've just not had the time for posting things lately.
However, I can offer some federal monitoring nuggets as stocking stuffers:
418.9000, 156.7 pl - DEA repeater with OTAR data, heard in the area of LAX.
167.3375 MHz, P-25 - Interesting FBI surviellance operation in the Los Angeles area on Friday, December 22. Airborne observers were in a helicopter and the P-25 vocoder had an interesting time with the whine of the turbines in the backround.
166.9125 MHz, P-25 - Unknown agency in the Los Angeles area, with both encrypted and clear traffic.
163.2125 MHz, P-25 and 163.6375 MHz, P-25 - Both of these frequencies were reported as being used by some sort of simplex operation in the Portland, Oregon area this past week. No idea who the agency is yet.

Little Rock Federal Scanning - Updated

I'm set up in Little Rock, Arkansas for the weekend and will have some time for searching the federal bands. Here's some of what I've been hearing:
163.8125, 131.8 - US Marshals
163.8125, 136.5 - US Marshals
166.7125, 146.2 - Unknown repeater, sounds like maintenance types
168.3625, 146.2 - Unknown repeater
168.5250 - Paging, McClellan VA Medical Center
169.5875, P-25 - Little Rock Air Force Base Security Police
173.1375, P-25 - Unknown, likely Little Rock AFB
173.4375, P-25 - Little Rock Air Force Base, sounds like base security police
173.5375, 118.8 - Unknown repeater
173.5875, P-25 - Little Rock Air Force Base, Fire / Crash Net
406.1625, P-25 - Motorola SmartNet trunked system 4628
406.3625, P-25 - Motorola SmartNet trunked system 4628
406.5625, P-25 - Motorola SmartNet trunked system 4628
406.7625, P-25 - Motorola SmartNet trunked system 4628
406.9625, P-25 - Motorola SmartNet trunked system 4628
407.1625, P-25 - Motorola SmartNet trunked system 4628
407.3625, P-25 - Motorola SmartNet trunked system 4628
409.7625, P-25 - Motorola SmartNet trunked system 4628
409.7375, D664 - US Postal Service
415.2000, 103.5 - DHS Federal Protective Service
418.7375, D664 - US Postal Service, input to 409.7375
418.9500, 156.7 - DEA
419.1750, 210.7 - DHS Federal Protective Service, input to 415.2

The UHF trunked system noted above was originally reported as being located at Little Rock Air Force Base. However, I was unable to detect any of these or any other 406-420 MHz signals radiating from the base as I drove around the base perimeter today. The control channel on 406.1625 MHz started to come in very weakly as I drove back south to Little Rock, and was still very weak at my hotel. Since all the radios using this system are running encryption, I'm calling this "Unidentified" for now.

CBP Comm Center Alert

Apparently a suspicious white powder was discovered in a package delivered to the Customs & Border Protection National Law Enforcement Communications Center in Orlando. You can read about the incident here:
http://www.orlandosentinel.com/news/local/newsletter/mu-html/orl-bk-powder120406,0,5204040.story

Although the powder turned out to be harmless, I wonder who would be sending such things to the NLECC.

Note that the CBP NLECC is not the same dispatch center as the US Postal Inspectors NLECC. You'll be able to read more about the USPS NLECC in the January Fed Files.

The Customs and Border Protection NLECC (Pre-9/11 and DHS, known as SECTOR, now heard on their radio frequencies as CHARLIE 100) continues to operate the nationwide communications network for the CBP as well as some other federal agencies that don't maintain their own national communications networks. Other agencies you might hear on the CBP channels include the ATF, Coast Guard, Department of Defense, ICE (Immigration and Customs Enforcement), NOAA and the Department of Agriculture. For a fairly current list of the CBP nationwide radio nets, check the Fed Files blog here: http://mt-fedfiles.blogspot.com/2006_05_28_mt-fedfiles_archive.html

Special thanks to those folks who have helped pass along this information!

Las Vegas Redux

Back in Las Vegas with some time to search the federal bands. Here are a few things I've been hearing:
165.2375, 100.0 - DHS CBP NET 1, with OTAR data.
168.4375, 114.8 pl - Analog repeater being keyed up by noise on the input side.
172.7625, P-25 - 14-xx units talking about heading back to the office.
413.6000, 103.5 pl - USPS sounds like a postal sorting facility.
418.9000, 156.7 pl - DEA with OTAR data.

Lots to hear in Las Vegas, federal, military and others. But I can't seem to find enough time to spend with the scanners, and the places I've been working & staying have a terrible amount of RF hash in the area that just wipes out the radios!

Justice IWN News

A recent article on the Government Computer News web site http://www.gcn.com has some insight in to the progress of the Justice Integrated Wireless Network,

http://www.gcn.com/print/25_32/42518-1.html

The article indicates that the next wave of IWN installation may be the US Southern Border region.

TSA Oddity at SFO - Updated!

A while back I asked Fed Files readers to keep an ear out for new frequencies that might be used by the Transportation Security Administration. Well, I found a new one, but not quite what I was expecting!

While changing planes at San Francisco International Airport (SFO) I had time to run my Uniden 396 scanner in Close Call mode and found the TSA operating on 469.5000 MHz, DPL 023! I confirmed that many, but not all, TSA personel were carrying UHF Motorola Radius or similar model hand-held radios. I was also able to confirm the transmissions I was hearing were from the TSA checkpoint near my gate. I was not able to see if they were using any additional UHF frequencies.

So what's up with that? I assumed that all the TSA operations had gotten their P-25 VHF radios long ago, but maybe they are awaiting new model radios. I have noticed that some TSA operations have newer XTS radios than were originally issued.

Oh, and I was able to confirm that 170.6250 MHz P-25 is the Customs & Border Protection operations for International Arrivals at SFO.

UPDATE - I was reminded by several members of the Fedcom e-mail list about the fact that the screeners at SFO are not really TSA, but work for a sub-contractor, in this case Covenant Aviation Security. If the federal contract with the TSA does not provide for radios to be supplied, I guess the contractor is responsible.

Justice IWN Marches On!

Until recently the Justice Integrated Wireless Network (JIWN) testbed trunked system operated within the state of Washington, but now the system has started to creep south into the Portland, Oregon area. Last week several new P-25 VHF control channels suddenly hit the airwaves. A group of us in the area have started trying to map out these new sites as they come on line, and here's what we've found so far:

170.7250 Site 119 Portland-Mount Scott
170.8375 Site 119 Portland-Mount Scott
170.9375 Site 119 Portland-Mount Scott
172.0625 Site 119 Portland-Mount Scott
172.2125 Site 119 Portland-Mount Scott
172.4125 Site 119 Portland-Mount Scott
167.5125 Site 120 Portland-Germantown Rd.
167.6625 Site 120 Portland-Germantown Rd.
168.5875 Site 120 Portland-Germantown Rd.
168.9125 Site 120 Portland-Germantown Rd.
169.2375 Site 120 Portland-Germantown Rd.
169.9375 Site 121 Portland Metro Area
171.6625 Site 121 Portland Metro Area
170.8625 Site 122 Portland Metro Area
171.6125 Site 122 Portland Metro Area
172.1875 Site 122 Portland Metro Area
167.6125 Site 123 Portland
170.9875 Site 123 Portland

This information is very preliminary. We've been hearing the radio techs setting up these new sites and testing various systems. Some of the sites have not been activated yet, so more frequencies will be coming soon. Most of the traffic has been un-encrypted, but encryption has been the primary mode on the rest of the JIWN system.

Press reports indicate that final contracts for this nationwide JIWN project may be finalized by early 2007, so we'll see when this system starts appearing in other parts of the country.

"Historic" Federal Photos

While going through some files yesterday, I came across a couple of photos I shot back in 1983 on a driving trip through El Paso, Texas. These are some of the antennas that were on top of the El Paso Intelligence Center, or EPIC. EPIC was and is still a major coordination center for the border interdiction efforts of the DEA, Coast Guard, Customs and other agencies. At the time I took these photos EPIC was located along I-10 in mid-town El Paso, but since has been moved on to the Fort Bliss military base.

http://www.dea.gov/programs/epic.htm

You can click on the photos for a closer look at the UHF satcom antennas.

Postal Inspectors Continue P-25 Upgrades

While searching through the federal UHF band (406.1 to 420 MHz), I often run in to frequencies used by the US Postal Inspection Service. The most common channels used by the Postal Inspectors have been 414.7250, 414.7500 and 415.0500 MHz. However many cities are in the process of upgrading to P-25 digital radio systems and many cities have changed frequencies. The Postal Inspection Service has also moved to 2 regional dispatch centers that they are calling NLECC, or National Law Enforcement Control Centers. Many listeners have reported hearing NLECC (heard as"En-Leck") calling various "IDA" units in the field.

This week I am hearing NLECC Fort Worth doing some radio tests in the Portland, Oregon area on 407.1375 MHz. This frequency has been noted in the past with occasional traffic, but was always encrypted. So far most of these tests with NLECC Fort Worth and Portland have been in the clear, but we'll see how long that lasts.

Also have confirmation of the Postal Inspectors repeater in the Boston area, 409.9375 MHz with an input of 418.9375 MHz.

Detroit Federal Scanning - Updated!

Here's what I've been finding active in Detroit the past few weeks. I'll be updating this list as I find more active frequencies:

162.2375, CSQ - Unknown
163.6250, 107.2 - DHS Customs and Border Protection
163.9875, P-25 - Encrypted, most likely FBI
164.3875, 110.9 - Probably US Postal Service truck operations

169.9500, 110.9 - Probably USPS, referenced "A Dock"
170.5500, P-25 - Encrypted, likely FBI
170.8250, 167.9 - FBI repeater
170.9500, P-25 - Encrypted, likely FBI
172.9000, P-25 - TSA

417.2000 - DHS Federal Protective Service
418.7500, 156.7 - DEA F3 aerial surviellance

173.8125 MHz and ROSS / JENA Call Sign

I recently posted that 173.8125 MHz was a mystery frequency in my home base area of Portland, OR. The frequency is P-25 digital with almost 100% of the transmissions encrypted. I was finally able to positively identify the frequency as the FBI with the help of ROSS 25.

On Monday morning, October 9th, I caught ROSS 25, an FBI observation aircraft, calling Portland International approach control, telling them they would be working over downtown Portland at 4000 feet. Shortly after that transmission, 173.8125 MHz came alive with CLEAR P-25 traffic from "25", indicating they were having a tough time following the target on the ground! So don't give up on those encrypted channels!

Speaking of ROSS aircraft call signs - A poster on the MILCOM e-mail list is reporting that in his area the FBI aircraft have started using the call sign JENA (GINA, JEANA?) for flight operations. I've also received confirmed reports from the Seattle area of an aircraft previously heard as a ROSS flight now using the JENA call sign. And a message from South Florida indicates a JENA or JEANNA flight has been heard regularly down there. Anyone else hearing this call sign change for the FBI surveillance flights?

Chicago Federal Monitoring

While no means a complete list of federal activity in the Chicago metro area, here's what I've been hearing the last few days of my visit:

162.7875 P-25 US Marshals

Goings On

It was noted on Friday, September 29th by an Los Angeles area listener that he heard a new P-25 repeater being tested on 172.7375 MHz. I was in the area on Friday and Saturday but was unable to catch any traffic on this frequency. Anyone else in the SoCal area heard this frequency active?

And in my home base of Portland, OR there continues to be a "mystery" operation taking place on 173.8125 MHz. This is a P-25 simplex net, and they are encrypted 99.9% of the time. I've only managed to catch 1 or 2 transmissions in the clear.

Got any mystery frequencies in your list? Please let us know about them at the Fed Files and Monitoring Times!

What's Coming Up in MT

Coming up in the November Fed Files will be a look at the new FAA VHF nationwide communications system frequencies, a close look at New York City federal trunked systems and some additional Pittsburgh monitoring information.

In January we're going to run a Fed Files contest. Details will be coming soon!

We're also working on a project to organize all the Bureau of Prisons facilies with information on their UHF trunking systems. If you monitor any of these federal prisons systems, please feel free to pass along that data to the Fed Files!

DHS ICE in DFW

I've received some reports from the Dallas Ft. Worth Metroplex of a new DHS Immigration and Customs Enforcement repeater in operation.

The P-25 repeater is on 163.7000 MHz with apparently two input frequencies, 162.8500 MHz and 168.9750 MHz.

I am currently working on an "Up Close" look at ICE and their radio systems for a future Fed Files column, so if you have any frequencies of interest, feel free to pass them along!

Atlanta Trip

I made a very short trip through Atlanta this past week. I wasn't in town long enough to do much monitoring, but did catch a couple of hits...

164.6500 MHz - P-25, US Secret Service TANGO
167.3375 MHz - P-25, FBI in Atlanta
167.7875 MHz - DES, Heard this near the town of Auburn, Alabama. I don't know if this is the local area FBI repeater, but was active while I was there.

9/11 Anniversary Visit

On Saturday, September 9th, I was preparing to leave Pittsburgh and happened to catch some of the preparations for a 9/11 Anniversary visit from President Bush. Apparently Pittsburgh International Airport was used as a jumping off point for the POTUS visit to Shanksville, PA, the site of the United flight 93 crash.

I first caught the tower clearing a flight of 3 CH-53 Marine helicopters were all painted in the "United States of America" colors. All three landed and taxied directly over the a hanger at the AF Reserve ramp. Shortly after these was a flight of 2 UH-60 helicopters using the "Nighthawk" call sign landed, also taxied over to the AF Reserve ramp and inside a hanger.

While watching all this I did catch some P-25 comms on USSS Oscar
(164.8875), WHCA Sierra (166.5125) and some DES on WHCA Zulu (171.2875). Seems like I have noted on other Presidential events I've been around, the WHCA hasn't switched over to P-25 entirely yet...

DEA Update

Since some DEA channels were recently discussed on the FEDCOM mail list, I thought I'd post my list of DEA UHF frequencies that was originally appeared in Fed Files and published in the November 2005 in Monitoring Times. Here are all the UHF DEA frequency allocations I have in my database:

HIDTA stands for High Intensity Drug Trafficking Area and is a program that concentrates resources on major drug trafficking areas in the United States. HIDTA operations normally involve federal support of local police operations that are involved in drug enforcement, www.usdoj.gov/dea/programs/hidta.htm.

Coast Guard UHF Frequencies

Officially the US Coast Guard moved it's UHF airband frequencies at the beginning of 2006. This was done to move their frequencies out of the 380-400 MHz DoD Land Mobile band. Here are the new frequencies:
237.9 MHz - Operations (secondary)
326.15 MHz - Air-to-Ground (primary)
345.0 MHz - Operations (primary)
379.05 MHz - Air-to-Ground (secondary)

However, don't take out the old Coast Guard UHF frequencies! It appears that some units are still using them for air-to-air tactical and training ops:
381.7 MHz
381.8 MHz
383.9 MHz

Federal Interoperability - Updated

Some new federal interoperability frequencies have become active in the Lone Star state recently.

170.7250 MHz, P-25 is known as "Dallas East" in the DFW Metroplex,
171.4375 MHz, P-25 is known as "Dallas West".

The same frequencies have been heard in the Houston area, but they were called "L-1" and "L-2".

I've also received information that the 171.4375 MHz frequency is used as a federal interop channel in the Philadelphia area. It is referred to as the "FIO" channel.

Anyone else hearing activity on either of these frequencies?

Twin Cities Fed Scanning

I'm in the Minneapolis / St. Paul area for the next couple of weeks, so I thought I'd post a few things I've been hearing up here. Unfortunately the hotel I am staying at is in the middle of RF hell and it's tough to get much of anything there...

I'll be updating this list as my stay up here continues...

TSA Busy!

With the security level at US airports now at ORANGE, the TSA has been extremely busy with the added security checks. If you live near an airport with commercial air service, try these frequencies and see what's going on:

166.4625 MHz - DHS Common
169.3000 MHz - TSA input to 172.9000 repeater
172.1500 MHz - TSA Simplex
172.9000 MHz - TSA Repeater or Simplex

All TSA communications are using P-25 digital mode. This channel plan should be used nationwide, with the exception of the DFW Airport in Grapevine, Texas. They are using a repeater on 169.1625 MHz, input of 165.0750 MHz. So far no encryption has been noted on TSA frequencies.

USCG "LANT" & "PAC" List

I've recently received some requests for information on the current status of the US Coast Guard "LANT" frequency lists. They have been floating around the Internet for a while but they seem to vary from source to source. The LANT designation appears to be short for ATLANTIC, however these frequencies are noted in use all over. Here's one of several versions of the LANT channels and some use notes:

155.4750 LANT 01
163.1750 LANT 02 USCG C3 Repeater (162.050 in)
162.1250 LANT 03 USCG TAC 1
162.2250 LANT 04
162.2500 LANT 05 USCG Operations
162.3250 LANT 06 USCG TAC 2
162.3500 LANT 07
162.6125 LANT 08
163.0500 LANT 09 USCG Enforcement (162.125 in)
163.1750 LANT 10 USCG Simplex
163.3750 LANT 11
164.3000 LANT 12 NYC
164.9125 LANT 13 NYC Repeater - Harbor Patrols
165.2375 LANT 14 DHS CBP Customs TAC 1
165.2625 LANT 15 USCG Law Enforcement C3
165.3125 LANT 16
165.3375 LANT 17
164.7750 LANT 18 US Army Corps of Engineers (165.975 in)
165.2375 LANT 19 DHS CBP Customs NET 1 (166.4375 in)
166.4625 LANT 20 DHS Common
165.2375 LANT 21 DHS CBP Customs NET 6 (166.4875 in)
166.5875 LANT 22 DHS USCG Tactical
167.9000 LANT 23 DHS USCG Portable Repeater Talk-Around
164.5500 LANT 24 DHS USCG OCDETF Repeater(168.8625 in)
171.3375 LANT 25 USCG Law Enforcement C4

There have been many variations of this LANT list, but this seems to be the most current. And yes, I have some frequencies that are identified as "PAC" channels as well. These are reported as allocated to the USCG District 11 (Southern California):

165.3375 PAC 01 (162.1250 in)

167.9000 PAC 02 (162.3250 in)

165.3125 PAC 03 (164.3000 in)

165.3125 PAC 04

164.3000 PAC 05 (165.3125 in)

165.3375 PAC 06

162.1250 PAC 07 (166.3375 in)

168.5000 PAC 08 (165.3125 in)

I have no current info on the use of these PAC channels. But I did hear from a listener in Southern California who heard two CG helos on 163.1750 MHz and referred to it as "LE-4".

Any more additions or corrections? Let me know!
