Operation Mountain Guardian 9/23/11

http://www.douglas.co.us/Operation_Mountain_Guardian_Emergency_Exercise.html

Operation Mountain Guardian is a terrorism-based emergency response drill that will be taking place in the Denver area this Friday, September 23rd. The drill involves many public safety agencies in the Denver Metro area and will include participation by federal agencies, including the FBI and Federal Protective Service.

This represents a rare opportunity to monitor the activities of the different agencies and see what is being used for communications. Be sure and keep an ear on the federal interoperability channels, as well as the DoJ "25-Cities" repeaters in the Denver area:

“DEN IO N” 170.6625 MHz (DENVER NORTH)
“DEN IO E” 171.9875 MHz (DENVER EAST)
“DEN IO C” 171.4375 MHz (DENVER CENTRAL)
“DEN IO S” 172.1875 MHz (DENVER SOUTH)
“DEN IO W” 167.2625 MHz (DENVER WEST)

Mexican Cartel Radio Network

I have encountered news reports in the past that suggested some of the Mexican drug cartels were utilizing a wide-area, encrypted radio system to outsmart both the Mexican and US authorities. It appears that the Mexican military was able to take down this network:

9/11 Anniversary Alerts

With the 9/11 10-Year Anniversary coming up tomorrow, many are speculating about the heightened security around the country, including federal and military installations.

There are news media reports that some "unsubstantiated yet credible" threats that have caused some increase in local, state and federal law enforcement activity. Keep searching the federal frequency bands for possible activity over the next 48 hours or so...

New USCP Radio System

The US Capitol Police are one of the federal agencies in the Washington, DC area that are still running analog radios. They have received some criticism for not yet upgrading to the federally backed APCO-P25 digital standard. But there appears to be change on the way.

A bid has been posted from the US Navy in Lakehurst, NJ for a multi-channel VHF P-25 system:

https://www.fbodaily.com/archive/2011/01-January/15-Jan-2011/FBO-02359641.htm

This system is part of the USCP radio modernization program and will be used by the US Capitol Police in the DC area. Some frequencies have been posted that are related to this new system:

Channel Number Transmit Receive
1 169.5750 162.2500
2 169.8375 162.6125
3 170.1375 162.8000
4 170.3750 163.1625
5 170.5750 163.6000
6 171.0000 164.0125
7 171.4125 164.3250
8 171.7875 164.6125
9 172.3875 164.8125
10 172.6875 165.0375
11 172.9625 165.5375
12 173.1625 165.7750
13 173.4750 166.2250
14 173.8125 166.4250

In addition to these trunked system frequencies, the bid proposes some "Travel Channels" to be used outside of the coverage of the DC system;

Travel 1: TX 168.3500 RX 163.1000

Travel 2: TX 173.5250 RX 166.4500

Travel 3: TX 173.8750 RX 166.4750

Unknown P-25 UHF System

I'm down in the Norcross, GA area with the PGA Championship Golf TV coverage this week, and started picking up a UHF trunked system I have no info on.

I'm getting a control channel on 406.7750 MHz, P25 System ID of 3B9, WACN BEE00, Site 103. It shows connected to Site 101 (406.1125), Site 102 (408.8375) and Site 104 (408.8375). I'm thinking there might be some military connection as the tables show a 380 MHz band available.

It's not coming in super strong up here northeast of Atlanta, but it is consistent. None of these frequencies or system information shows up in Internet searches or Radio Reference.

My first thought was that they could be upgrading the Federal Protective Service trunked system in Atlanta to P-25. It is also a 4 site UHF system. But, when I drove up from the airport last week I don't recall coming across these trunked sites in my initial scan/search of the federal bands.

Anyone want to take a guess at who or what this system is and where it's located?

Border Activity

In addition to DHS Border Patrol traffic, some listeners have reported activity that may be related to National Guard support of border enforcement.

From Eagle Pass, Texas comes a report of 391.0500 MHz, P25 with a NAC of N500. The report says the traffic is encrypted full time and not from Laughlin AFB.

Reports also mention some unknown type digital traffic in the 380-400 MHz bands that are not P-25, and rumored to be coming from Piedras Negras, Mexico.

UPDATE!
An alert reader pointed out that there is a wide-area TETRAPOL trunked system used by the Mexican Federal Police Forces, which may account for the unknown type digital traffic in the 390-400 MHz band.

Upcoming POTUS Bus Tour

An upcoming bus tour of the Midwest US has been announced by the White House. President Obama will embark on a three-day tour from August 15 through 17. The administration said Wednesday that the trip had long been planned, but wouldn’t outline an itinerary:

http://thehill.com/blogs/blog-briefing-room/news/175185-obama-plans-august-bus-tour-of-midwest

There is a line in the story that mentions that the "Secret Service purchased two armored buses for its fleet earlier this year". This could be an interesting opportunity for some listeners along the bus tour route to see what they have incorporated in these buses for communications.

UPDATE:
Apparently the buses mentioned in the above article were purchased from this company:
http://www.hemphillbrothers.com/

They list several political tours as well as some federal government agencies as clients.

NOT the Presidential Tour bus, but an interesting possibility:









UPDATE 2!

Well, not much reported from monitoring the POTUS bus tour of the midwest, but did get a real picture:

Bureau of Prisons Changes

I have been seeing reports of changes occurring in some of the US Bureau of Prisons (BoP) UHF radio systems in use at federal prison facilities. In some cases some frequencies have been changed, in others the entire system seems to have been replaced.

Most recently I heard from a source in Southern California that the Metropolitan Correctional Center San Diego may have a new radio system going on line. A new Motorola control channel was heard on the air on 408.6125 MHz, with a System ID of F008. Later the control channel moved to 410.0000 MHz with the same System ID.

The original MCC trunked system in San Diego uses these frequencies:
System ID 6426
408.3000
411.0250
412.5759
414.1250

It would appear that the system is being replaced to conform with the federal UHF 9 MHz channel offset, with repeater outputs being at the low end of the spectrum, and the repeater inputs being +9 MHz.

Also, reports of a new UHF trunked system have been reported on Radio Reference. A control channel has been heard on 406.2125 MHz in the Fresno County area. The control channel is reporting a System ID of EE2B. Not confirmed but the speculation is that it will be used by the new FCI Mendota:

DEA News

A couple of items regarding the Drug Enforcement Administration (DEA).

First, a reader sent me this link:

http://www.ok.gov/okwin/documents/OKWIN%20-%20Executive%20Committee%20-%20Meeting%20Minutes%20-%20%2807.22.11%29.pdf

This is a document containing the minutes from a meeting of the Oklahoma Wireless Information Network (OKWIN) Executive Committee. In these minutes, the DEA requested access and talk groups on the new statewide radio system. This quote appeared in these minutes:

"The DEA currently has UHF frequencies to conduct daily business. They really want to use the system for interoperability, but see the benefits of using the system for day-to-day business so it would be “nice to have.” The DEA coverage is limited in the NW and SE areas of Oklahoma, just as the OKWIN system is limited. So there is no great increase in coverage area for them. Also, the DEA plans on using a new VHF system planned in the future and then only maintaining a presence on the OKWIN system for interoperability."

This triggered some questions about the DEA moving to a VHF radio system. I think they are referring to the DEA's participation in the federal VHF Integrated Wireless Network (IWN), of which the Department of Justice is the primary user. The DEA is using the IWN in areas that it is operational. (In the Pacific Northwest, the DEA had their UHF radios taken away years ago.) But in areas that are not served by the IWN (which is most of the country), they not only remain on UHF, but have started to migrate to new P-25 UHF frequencies.

Which brings us to the second item, and updated list of the UHF P-25 channels that listeners in Texas and other Gulf states are hearing:

409.6250 MHz, N156 - Possible new F1
409.6750 MHz, N156 - Possible new F6
409.8125 MHz, N156 - Possible new F7
409.8250 MHz, N156 - Possible new F8
409.9000 MHz, N156 - Possible new F9
409.9500 MHz, N156 - Repeater, possible new F10
410.4125 MHz, N156 - Repeater/simplex, new 11?
411.1250 MHz, N156 - Simplex 1?
411.1750 MHz, N156 - Simplex
412.2000 MHz, N156 - Simplex 2?
413.9750 MHz, N156 - Simplex 3?
414.2000 MHz, N156 - Simplex, possible new 4 or 5
414.4500 MHz, N156 - Simplex, possibly new 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
418.8250 MHz, N156 - Input to 409.8250 repeater
418.9000 MHz, N156 - Input to 409.9000 repeater
418.9500 MHz, N156 - Input to 409.9500 repeater

It's also possible that the DEA will be going to the nomenclature of NET and TAC channels that many other DoJ agencies are now using. The NET channels will be repeaters and TAC channels being simplex.

DMAFB Trunked System Update

Just had a chance to monitor some changes at Davis Monthan Air Force Base in Tucson, Arizona. They have had a UHF Motorola trunked system there for a number of years, but now have started a separate P-25 UHF system as well.

The new system is using a System ID of 3F6 and the site at the base shows as Site 102. It is not showing as being networked with any other sites yet.

The frequencies are as follows:

409.2750
409.4500
409.5625
410.5625

All frequencies associated with this system were displaying a NAC of 3F0. These 4 frequencies were taken from the original DMAFB UHF system channels. It's unconfirmed, but this may be the start of converting the entire base to a single P-25 trunked system.

The system now has some limited users, and at least one talk group was being heard over both systems. But most of the activity is still on the original base trunked system:

Nellis AFB P-25 System Updates

Back in May, I posted some initial reports of an update to the UHF trunked system used by Nellis AFB in Las Vegas. You can find that post here.

I'm now in Las Vegas and have started monitoring and mapping this new system. The first item of note is that this is a separate, true P-25 trunked system and not part of the NNSA Motorola trunked system that Nellis was a subscriber to in the past. Some of the early information had listed this new System ID as "000F", but it is "00F", which indicates that it is a P-25 system (P-25 systems use a 3-digit system ID as opposed to a 4 digit ID used by Motorola Type II systems).

Here are the frequencies in use at Nellis now:

406.5000
406.7875
407.1875
407.3000
407.5000
407.8625
408.1500
408.9625
409.1125
409.5625
409.7125
410.6500

With the exception of 407.1875 and 407.5000, these frequencies were at one time all part of the NNSA Motorola trunked system that serves the entire southern Nevada area. This P-25 system appears to be standalone and is not networked to any other sites.

The original NNSA Site 10 that covered Nellis is now on the air on 408.3875 MHz, and appears to still be in use by a few users.

FEMA Mobile Units

Saw this web page on a recent list posting and thought it was interesting;

http://www.core77.com/blog/transportation/a_tour_of_femas_fleet_19969.asp

It's a nice look at FEMA's Mobile Emergency Response Support (MERS) command units and the various versions and sizes that they come in.

UPDATE: Fixed the messed up link I had earlier.

CBP Announce New MEA

U.S. Customs and Border Protection announced today its new King Air 350, twin engine Multi-role Enforcement Aircraft (MEA), providing the Department of Homeland Security unmatched capabilities to patrol the skies along the nation’s land and maritime borders.

Another 414.5625 Report

I have monitored some encrypted P-25 transmissions in the Houston area on 414.5625 MHz with a NAC of N168. Others have also heard it in use in the Charlotte, NC area. I've recently received a report of encrypted traffic on this same frequency in the Boston area, however reports are that the NAC was showing N169. It's possible that whatever agency this is has multiple NACs for different repeaters in the area.

Still no indication as to what agency this is...

Royals Visiting California

Members of the British Royal Family will visiting the Southern California area this coming week, and it could make for some interesting monitoring.

The Duke and Duchess of Cambridge will arrive in Los Angeles on July 8. Their schedule calls for several days of travel and appointments around LA and other cities;
http://www.kcoy.com/story/14924375/schedule-released-for-royal-visit-to-california

Both Secret Service and Department of State Bureau of Diplomatic Security have possible involvement in security operations for the Royal visit, but media reports have mentioned the DoS as being the agency for this trip.

If scanning the visit, be sure and keep an ear on local and CHP channels for activity, and search the UHF federal band (406-420 MHz) for State Department activity. And don't forget there will most likely be some British Royal security presence as well. The last time I ran into British VIP security in the US they were using some 160 MHz frequencies.

For a list of Secret Service channels, you can check my previous post,
http://mt-fedfiles.blogspot.com/2008/02/secret-service-frequency-list.html

Here is a quick list of possible Department of State Bureau of Diplomatic Security frequencies. They should be all P-25 digital and utilize a NAC of either N293 or N0F0. Be sure and let me know what you hear active:

406.3750

407.2000

407.5000

407.6000

407.8625

NYC Updates on RR

Some additional, anonymous federal frequencies have been added to the New York City frequency database on Radio Reference:

http://www.radioreference.com/apps/db/?aid=3378

Sifting through the updates, I spotted a couple of interesting items. First, if the contributor is accurate, several VHF P-25 channels that I have caught in the past using a NAC of 864 are identified as being the US Marshals Service, New York. They have been active, but due to encryption, the identity was unknown. Also unknown if this is a NAC used by the USMS nationwide.

Secondly, there are 9 VHF channels listed as being "Federal Interoperability" frequencies. I have noted one or two of these frequencies active during the weekly tests, but some of these are previously unknowns, or used by other agencies. Keep an ear on these and let me know if they are active;

164.4750, N653 (Also used by the National Parks Service in New Jersey)
166.5375, N653* (See Update below)
166.7500, N653
167.3500, N653
167.7875, N653 FI/O 1 (Weekly interoperability roll call tests heard here)
168.6625, N653
171.1125, N653
171.1750, N653 FI/O 2 (Heard during New Years Eve in Times Square events)
172.2875, N653

The frequency of 414.7500 MHz, 82.5pl was also utilized for interoperability tests in the past.

UPDATE!
It slipped past me initially, but I was reminded that the frequency of 166.5375 MHz is actually the input to the BATFE nationwide repeater of 165.2875 MHz. The BATFE uses a NAC of 650 on the repeater output, but uses various NAC's from 650-65A on the inputs. I suspect that they are using 166.5375 MHz, NAC 653 as the input to the BATFE repeater in the area, and the listener assumed that the NAC of 653 meant it was part of the Federal Interop channels.

Also, the inputs for the two known federal interop repeaters are not among the channels that were posted on RR. The input to the 167.7875 MHz repeater is 164.7375 MHz, and the input to the 171.1750 MHz repeater is 162.2875 MHz.

EPA Flys Over Dallas

Apparently in preparation for the celebrations of the Dallas Mavericks NBA Championship, the Environmental Protection Agency (EPA) will be doing low-level flights over the downtown Dallas, Texas area;

http://today.msnbc.msn.com/id/43404526/ns/local_news-dallas_fort_worth_tx/t/dont-be-alarmed-low-level-flyovers/

The flights are for sampling air and other environmental readings in order to detect anything unusual that might be released, either intentionally or accidentally.

The next Fed Files column will feature a profile of EPA radio channels. I have not received any information on what the EPA flights in Dallas might be using.

TSA Conducts Multi-State Exercise

If you think the TSA only functions at your local airport, think again:

http://www.mariettatimes.com/page/content.detail/id/536701/TSA-conducting-security-exercise-.html?nav=5002

http://wvgazette.com/News/201006160894

As of Wednesday, June 15th, eports are that this was a multi-state exercise involving the VIPR (Visible Intermodal Prevention and Response) teams. The exercise involved inspections of power and chemical plants, rail terminals and shipping terminals, lock and dam complexes and natural gas pipelines. The exercise also involved local and state agencies as well.

DEA Changes in Dallas

Listener reports from the Dallas/Ft. Worth Metroplex seem to indicate that the DEA is starting to use some of it's new P-25 UHF frequency assignments there.

After many reports from the Houston area and other Gulf regions of the new UHF frequencies, reports are that 413.9750 MHz, NAC156 is in use around DFW. The original UHF channels are also still in use in analog mode as well.

For a complete listing of what's been found on the new UHF channels so far, check out this previous blog post:
