170.7250 MHz - Harrisburg, PA?

I was recently forced by an airline flight cancellation to drive from Pittsburgh to Atlantic City, NJ for work. While driving across on I-76, the Pennsylvania Turnpike, I started picking up a lot of P-25 clear activity on 170.7250 MHz. As previously blogged, this frequency has been used as a Federal Interoperability repeater in some cites, but I have not received reports of it being used in the Philadelphia area. The signal was quite strong and seemed to be centered around the Harrisburg area. It finally got weak and was not heard in the Philadelphia area.

The activity was a surveillance operation. First names were used and no specific locations were identified. Could have been anyone of a dozen federal agencies. Similar traffic has been heard in the Pittsburgh area on a P-25 repeater on 169.8000 MHz. Pittsburgh monitors report that some locations heard on this repeater seem to indicate that the operations were taking place in Philadelphia, and this frequency was somehow tied in to the Philly repeater.

It's quite possible that this Federal Interop system has these repeaters in various cities tied together, but I have not confirmed this yet.

"VOLCANO - Out"

With the passing of Lady Bird Johnson this past week, I was reminded of many trips through the Austin, Texas area in years past. Often I could pick up the US Secret Service detail that was stationed at the LBJ Ranch near Johnson City, Texas. They could be heard using the call sign VOLCANO. I think that they used to use the Secret Service CHARLIE channel, 165.3750 MHz, but my old logs from those trips have been lost for a while... UPDATE: A friend in Texas reminded me that VOLCANO had a MIKE (165.2125 MHz) repeater.

By the way, LBJ's call sign was VOLUNTEER and Lady Bird was known as VICTORIA.

164.9625 MHz Anyone?

I am curious if anyone is hearing any law enforcement activity on 164.9625 MHz in your area. This frequency has been a long used Customs tac frequency that folks in South Florida have been hearing for years. In the old Customs channel plan, this was often referred to as "A-7", and under the new DHS channel plan it may be known as TAC 21. It appears to be used primarily by the Customs Air Marine Division and was very active at the recent Super Bowl in Miami.

What I am curious about is if anyone outside of South Florida has heard the use of this channel. This frequency is not an exclusive DHS Customs assignement, so I'm curious if it is used anywhere else. If you hear any activity on this frequency in your area, please let us know at the Fed Files!

UPDATE - Here is what readers have sent me so far:

Boston - US Postal Service - 164.9625, 162.2 pl - input to 173.6375, 162.2 pl repeater

Federal Interop "25 Cities" Frequencies

In the January 2007 Fed Files, I mentioned the Justice Department's "25 Cities Project". Basically the program focuses on 25 major US cites and helps plan and provide radio interoperability between federal and local radio systems. You can find some very informative downloads at the project’s web site:
http://www.ojp.usdoj.gov/nij/topics/commtech/25cities/

(NOTE: It appears that the DoJ has moved all the 25 Cities downloads behind a login page. However you can do a search for "Department of Justice High Risk Metropolitan Area Interoperability" and you should still find access to all of the individual PDF files for each city.)

I have recently received some additional frequencies that may be part of the 25 Cities Project. Here are a list of what I have so far. If you have anything to add, please let us know!

Chicago
168.8875 - P25 repeater
168.9125 - P25 repeater
170.8125 - P25 repeater
171.4375 - P25 repeater
171.6875 - P25 repeater
172.2125 - P25 repeater

Dallas / Ft. Worth
170.7250 MHz - P25 repeater "Dallas East"
171.4375 MHz - P25 repeater "Dallas West"

Houston
170.7250 MHz - P25 repeater "L-1"
171.4375 MHz - P25 repeater "L-2"

New York City
167.7875 MHz - P25 repeater

Philadelphia
171.4375 MHz - P25 repeater "FIO"

Postal Inspectors Update

I recently had a nice email from a Fed Files reader who was interested in finding the US Postal Inspectors active frequencies. As we have noted here, the Postal Inspectors are in the process of changing around some of their frequencies and upgrading to P-25 digital radios. Some cities are still analog with DES encryption, others have moved to P-25 digital and some have both!

I thought I would compile what I currently had logged and share them. If anyone has some additional info, please feel free to pass it along!

Atlanta - 407.7250, P-25

Boston - 407.7750, 409.9375, 414.7500

Chicago - 406.3375, 414.7500, 415.0500

Cleveland - 409.9375, 414.7500

Dallas - 414.7500, 417.6000

Houston - 407.1375, 407.7250, 414.7500

Little Rock - 406.9625 (Not Confirmed Yet)

Los Angeles - 415.0500

Memphis - 407.1375, 407.7750

Miami - 407.7750

Minneapolis - 407.7250, 407.7750

NYC - 414.7500, 415.0500, 416.2250 + UHF trunked system on Manhattan

Newark - 407.7250

Oklahoma City - 417.7000

Orlando - 406.3375

Philadelphia - 406.8125, 409.3250, 409.9375

Pittsburgh - 406.3375, 407.1375, 407.7250, 407.7750, 415.0500

Portland - 407.1375, 407.7750, 415.0500 - P25

San Jose, CA - 413.6000, 414.1500, 414.7500, 415.0500

Tampa - 407.1375, 415.0500

Washington DC - 407.7750

In most cases, the 406 through 409 MHz repeaters are P-25 digital and the inputs to those repeaters should be +9 MHz. The 414 and 415 MHz repeaters are still analog, most with DES or AES encryption. In areas that have moved to new 406 or 407 MHz P-25 repeaters, keep listening to the 414.7500 and 415.0500 frequencies, as they can still show up as simplex surveillance channels!

UPDATE - Several Fed Files fans have provided some updates to the list I posted. Thanks for all the information! I will continue to update this blog entry as more information is received!

Coast Guard New Haven

I was recently in the New London/Groton Connecticut area and was monitoring a lot of Coast Guard Station New Haven activity. The area of responsibility (AOR) for Station New Haven consists of almost 2/3 of Long Island Sound,extending from Black Rock Harbor to Clinton Harbor on the Connecticut shoreline and from Mattituck Inlet to approximately 2nm East of Mt. Sinai Harbor on the Long Island shore.

Besides the normal VHF marine channels, I did catch quite a few transmission on 162.1250 MHz, once known as LANT 03 or TAC 1. However, I was hearing the units calling New Haven refer to this frequency as CC-9 ("See-See-Nine"). Anyone hear channel designators like this before?

UPDATE - A kind blog reader suggested that I might have heard "CG" instead of "CC". Quite possible I guess...

Secret Service Call Signs

With all the candidates running for President in 2008, the Secret Service will have to come up with new radio call signs for each protectee. This article from the Washington post mentions that candidate Barack Obama has been dubbed "Renegade",

http://www.washingtonpost.com/wp-dyn/content/article/2007/06/16/AR2007061601079.html

This article mentions that President Bush (43) has a call sign of "Tumbler", which it was when he was Governor of Texas. But I do recall that after he was elected to President, his call sign was changed to "Trailblazer", with the First Lady known as "Tempo".

The July Fed Files column will feature a focus on Secret Service radio frequencies.

AMTRAK Police Operations

I'm currently working on a show in New York City that has us parked near Penn Station in mid-town Manahattan, and there are usually 3-6 AMTRAK police vehicles parked in the area between Penn Station and Madison Square Garden. This got my interest up in what AMTRAK police officers were using for radios.

I've seen requests on some lists for information about AMTRAK police operations and frequencies. A search of the Internet turns up little information, but I decided to try and piece together as much of it as I could. I think I saw a thread on AMTRAK police on the SCAN-DC list a while back. The frequencies of 173.3500 MHz and 173.3750 MHz came up, and someone pointed to an archived edition of the Capitol Hill Monitors newsletter that has some great info on the AMTRAK police radio channels: http://henney.com/chm/0299/.

Other web sites have indicated that the AMTRAK police in New York City may have additional channels besides the ones listed in the previous link: F2-160.8150 MHz, F3-161.2950 MHz, F4-161.2050 MHz, F5-161.2950 MHz, F6-161.2050 MHz. 161.3650 MHz is also listed in some sources as an AMTRAK police frequency. These are all channels in the standard US railroad allocations, so in theory they may be using any of the 99 available VHF channels. The 173.3500 and 173.3750 MHz frequencies are not exclusive federal allocations, so you may hear other users on these channels.

Here on location, I have been hearing what appears to the AMTRAK police operations on 161.2950 MHz, 131.8pl. There have been a few incidents over the last few days at Penn Station involving NYFD units, but nothing that seems to have made the news.

Got any confirmed AMTRAK police frequencies you want to pass along? Send them to the Fed Files and Monitoring Times!

NYC FBI Interop Check-In

I finally had a chance to catch the weekly (I think) test of the Federal Interoperability repeater in the New York City area. The test started at 10AM with "FBI Operations" calling a list of participating agencies on 167.7875 MHz, P-25 digital. The agencies that checked in with FBI Control included:

ATF New York
ATF Newark
US Attorney Eastern District
DEA New York
DEA Newark
FEMA
US Marshals Southern District
US Marshals Eastern District
US Marshals New Jersey
ICE New York
ICE New Jersey
CBP New York
CBP Tactical JFK
Coast Guard Sector New York
Secret Service New York
Secret Service New Jersey
IRS New York
Park Police Manhattan
Park Police Brooklyn
Postal Inspectors New York
Postal Inspectors New Jersey
US Attorney Long Island
Air Marshals New York
Essex County SO
Nassau County Police

Previous reports that I had received on this interop repeater said that they had heard this repeater tied to 414.750 MHz during these tests, but I did not hear any activity on the UHF frequency during this morning's test.

Earlier in the morning, I caught two FBI radio techs checking coverage of this repeater with a hand held radio. The gentleman that was mobile was north of the NYC area on I-287 near the White Plains area, which is apparently the northern limit on this repeater.

Washington DC Trip

I just spent a few days working in the Washington DC area. Too much to listen to there!!! Besides all the new trunked systems and military stuff, the federal bands are just hopping there with almost every federal frequency allocation being used.

Notes and frequencies from my trip will be featured in an upcoming Fed Files, but a couple of interesting notes:

In the July Monitoring Times Fed Files, there will be a feature on the Secret Service. As I noted on that column, the Secret Service has switched over the P-25 digital modes, but does not seem to be 100% full time encrypted. Some transmission on 165.7875 MHz (BAKER) were in clear P-25.

The Uniformed Division of the Secret Service is highly visible and very busy with encrypted P-25 operations on their VHF frequencies (also featured in the upcoming MT).

167.4125 MHz was busy with what sounded like a large, rolling surveillance operation by the FBI. Strangely it was all analog, in the clear. Perhaps units from different areas without the right encryption keys?

Most of the UHF federal band is full of Motorola and LTR PassPort trunked systems. But there are a few conventional systems in the UHF band there.

DoD military APCO P-25 trunked systems in the 380 MHz band are springing up like weeds in a back yard around the DC area. Hard to keep track of who's on first with those, as they are encrypted on about 80% of the traffic heard.

2007 National Hurrican Operations Plan

From the Office of the Federal Coordinator for Meteorology:

http://www.ofcm.gov/nhop/07/pdf/entire-nhop07.pdf

Interesting document with several references to communications. Here are a few highlites:

5.5.4.2.1. The 53 WRS shall only use the call sign "Teal ##," AOC shallonly use "NOAA ##," NASA shall only use "NASA ##," and NRL shall useonly Warlock587.ATC will provide TEAL and NOAA aircraft priority handling when specifically requested.

5.5.4.5.1. During NHOP missions, commencing 5 minutes prior torelease of dropsondes from FL190 or higher, the aircraft commander will broadcast in the blind on radio frequencies 121.5 MHZ and 243.0 MHZ to advise any traffic in thearea of the impending drop. Pilots shall not make these broadcasts if they will interfere with routine ATCcommunications, such as in the vicinity of an airport approach control facility. The aircraft commander is responsible for determining the content and duration of a broadcast, concerning a dropsonde release or sensor activation.

5.9.1. General. The 53 WRS WC-130 and NOAA WP-3D aircraft will normally transmit reconnaissance observations via the Air Force Satellite Communications System(AFSATCOM), commercial SATCOM or high frequency (HF) radio phone patch. Figures 5-12 and 5-13 depict the ASDL and AFSATCOM communications links. The NOAA G-IV will normally transmit WMO Temp Drop messages via commercial SATCOM. Flight meteorologists should contact CARCAH following the first fix, and periodically throughout the mission.
5.9.2. Air-to-Ground Communications (HF Radio). The weather reconnaissance crew may relay weather data via direct telephone patch to the weather data monitor. Monitors will evaluate these reports and disseminate them through the Air Force'sAutomated Weather Network (AWN) or to the weather communications facility at Suitland, Maryland. When requested, aeronautical stations will provide a discrete frequency for mission use, if possible. Specific radio procedures and terminology will comply with Allied Communications Publication 125, Standard Telephone and Radio Procedures. The use of IMMEDIATE precedence for transmission of hurricane reconnaissance data is authorized because of the perishable nature and potential operational impact of weather data. Data will be routed by direct phone patch between the aircraft and CARCAH.

5.9.3. Air-to-Air Communications. When more than one aircraft is known to be operating in a particular area of interest, the following frequencies will be used for airplane-to-airplane communications and coordination unless otherwise directed by air traffic control:• Primary: VHF 123.05 MHZ• Secondary: UHF 304.8 MHZ• Back-up: HF 4701 KHz USB

Definitely worth a look! Thanks to Robert Wyman for alerting me to this material!

415.2 Oddity In Memphis

Some strange happenings have been observed in the Memphis, Tennessee over the last couple of days. When I got in to town on Wednesday evening and started searching the federal bands, I came across a repeater on 415.2000 MHz that was keyed up all the time with a "beep-beep" about every 7 seconds. It was definitely coming from downtown Memphis, as I could get Close-Call hits from it and hear it without an antenna on the radio. This frequency is normally used by the Federal Protective Service in many cities and may still be used by General Services Administration maintenance operations in some areas.

On Thursday, while in Forrest City, Arkansas, the same constant-carrier with the "beep-beep" was heard on 409.3500 MHz while in that area. I was not able to determine where that repeater was located.

I actually sat and listened to the constant "beep-beep" signal on Saturday for a while. It appears that the repeater is still getting signals in to the input. I heard quite a few radio key-ups and actual voice transmissions, but it was like they were talking to someone that was never heard responding over the repeater. Most of the transmissions I did hear were maintenance related, i.e., getting doors unlocked, refrigerators not working, etc.. Again, I heard some units calling others, but would only hear one side of the conversation.

I know some repeater systems will transmit this "beep-beep" signal to indicate something needs attention, such as a commercial power failure, a control link failure or something along those lines. But what this means is a mystery to me!

New BoP System Info

In the quest to document and build a database of Bureau of Prisons radio systems, there have been some BoP facilites that we just don't have any information on. Some are located in rural areas that just may not have any listeners nearby. This is probably the case for the Federal Correctional Complex in Forrest City, Arkansas.

I happened to be in nearby Memphis, TN and made a side trip over to see what I could find about the FCC Forrest City's radio system. Here is what I found:

Federal Correctional Complex Forrest City

Motorola Type II SmartNet

System ID - a733

Base - 406.8125

Step - 12.5

Offset - 380

406.8125

407.4125

408.2125

408.8125

409.6750

410.5250

The system is using P-25 digital voice and seems to be very busy.

This system information will be added to the Fed Files BoP Database that is available for download on the Monitoring Times website. It is in the "Readers Only" section of the site, and requires a password found in the latest issue of Monitoring Times magazine.

Lawrence Livermore National Laboratory

The Lawrence Livermore National Laboratory in the San Francisco Bay area operates a multi-site UHF trunked system with sites all over. The system info was removed from the RadioReference web site at the request of the LLNL.

On a recent trip through San Francisco I found that there appears to be a site on this system located in or near downtown San Francisco. It is a Motorola Type II UHF system that is using P-25 voice. The system ID is 5434 and I found Site 6 to be coming in full strength with no antenna on the radio while I was at AT&T Park. Here is the site info:

406.1500 MHz - Control Channel, System 5434, Site 6

407.8625 MHz - Voice Channel

408.3875 MHz - Voice Channel

416.8625 MHz - Input to 407.8625

417.3875 MHz - Input to 408.3875

UPDATE: I have been informed that Site 6 of this system is in fact located at the Lawrence Berkley Lab, across the bay from San Francisco.

Hoover Dam

I had some spare time on a recent trip to Las Vegas, so we decided to take a trip out to the Hoover Dam and see what had changed in the last 10 years since I was there last.

As it turns out, quite a bit had changed. There is a fabulous new visitors center, a great parking ramp and the construction of the new bridge over the dam is quite impressive. But traffic still slows to a crawl well before you get to the dam, due mainly to the new security checkpoints that all vehicles must pass through.

Here is what I picked up on the scanner while at the dam:

163.1250, P-25 - Hoover Dam Police repeater

165.6000, P-25 - Hoover Dam Police input

166.3000

167.1500

169.8000, 173.8pl

170.0500

172.6000

Some of these frequencies are related to the Lake Mead National recreation Area. I also spotted a UHF omni and a UHF Yagi antenna mounted at the center of the dam, both pointed down towards the bottom of the dam. It might be that the dam operations are using UHF, but never found any active UHF frequencies while there.

Update At ORD

On my return trip through Chicago, I had more time to break out multiple scanners and try to figure out some of what I heard on my last trip.

First off, the 163.4750 MHz frequency does NOT appear to be the TSA on further listening. It is, in fact, the Immigrations and Customs Enforcement operations at the International Terminal at O'Hare Airport. However, it gets strange in that all the traffic on this repeater is also heard on another repeater on 163.7500 MHz, located somewhere nearby. These frequencies are quite busy with announcements as to incoming flights and baggage movement (thus my thinking it was TSA at first). I also heard one unit calling CHARLIE 100 about taking a subject under arrest to a holding cell. CHARLIE 100 is the Customs & Border Patrol National Law Enforcement Communications Center in the Orlando, FL area.

Next, I discovered the 165.8500 MHz frequency is actually the input to the ICE/CBP repeater on 163.6250 MHz, which does appear to be at ORD. I heard more than a few units switch between the 163.6250 and 163.4750 frequencies.

The 169.1625 MHz repeater does appear to be TSA, but have not confirmed the input. 172.1500 MHz is definitely in use by the TSA at ORD.

And finally, while searching, I got a couple of brief hits on 167.0375 MHz. I don't know who that might have been. All the frequencies listed in this blog entry were using APCO P-25 digital mode and un-encrypted.

New Dallas Frequencies

On a quick visit in the Dallas area, I discovered some new P-25 frequencies active in the downtown Dallas area. 406.6625 MHz (repeater) and 415.6625 MHz (input to 406.6625) appear to be a 24/7 security operation. Local sources are indicating that this is most likely the Federal Reserve Bank, located at 2200 North Pearl Street, a stone's throw from where I was staying.

New TSA Freqs Found???

While waiting for my delayed departure from Chicago's O'Hare Airport, I found what appears to be several new P-25 conventional frequencies in use by the TSA (Transportation Security Administration). This seems to continue the trend of the TSA showing up on new frequencies where they might have interference issues with another nearby commercial airport. Previously I had only heard the nationwide frequencies of 172.15 and 172.9 in use at ORD, but here's what is being used now:

163.4750, P-25 - Repeater that seems to carry a lot of informal traffic regarding baggage screening and personel assignments. I did not find the input to this repeater.

165.8500, P-25 - TSA operations, appears to be the input to a repeater on 169.1625 MHz.

169.1625, P-25 - TSA Operations at ORD. This frequency is also used by the TSA at DFW Airport in Grapevine, Texas.

172.1500, P-25 - TSA Simplex operations at ORD. This remains as one of the normal, nationwide TSA channels that is still in use at ORD.

While searching these out, I also came across a P-25 repeater on 163.6250 MHz, most likely an Immigrations and Customs Enforcement (ICE) repeater at ORD.

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:
