Can Tiny Scanners Be In Our Future?

After reading this item from the BBC:

http://news.bbc.co.uk/2/hi/science/nature/7050477.stm

I've got to believe a tiny receiver / scanner using nano-techology can't be too far fetched! But will it trunk-track a P-25 system?!?

JIWN Site in WDC?

I just noticed that the Radio Reference listing for the Justice Integrated Wireless Network (JIWN) now shows a site in Washington, DC.;

http://www.radioreference.com/modules.php?name=RR&sid=3509

It is showing as Site 160, using frequencies of 168.2625 MHz and 168.8875 MHz. I have not seen any posts from anyone in the DC area about this yet. It may have just show up on the air recently, as it was not there a few weeks ago when I went through the area. Can anyone in the DC area confirm this?

UPDATE! - I did hear from someone who did confirm this site is on the air, and has a voice channel of 173.5500 MHz associated with it.

Seems like the IWN sites area popping up in new places, but so far not along the US/ Mexico border, which was officially stated as the next phase of the IWN project.

ANOTHER UPDATE! - I was passing through Dulles International Airport (IAD) today and was unable to pick up anything on either of the listed frequencies. Reports are that this site is not really strong as Reagan National Airport either, so the site may not be in DC proper.

415.6625 MHz Near You?

I'm curious if anyone had started picking up transmissions on 415.6625 MHz or 406.6625 MHz?

I have confirmed these frequencies are being used at several branches of the Federal Reserve System. I am wondering if this is now a nationwide assignment for the Federal Reserve. Some locations are using P-25 digital mode, some are analog. Some locations are using the 406 frequency as the repeater input, some are using it as the repeater output.

Previously these frequencies have been unassigned and became available because of the 12.5 KHz channelization of the federal 406-420 MHz band.

TOPOFF 4 Radio Usage

Since the TOPOFF 4 exercise is now finished, at least on the public side, I thought I would share what I found as far as radio communications in the Portland area...

Tuesday's initial operations were mainly on the 800 MHz Portland area public safety trunked system, as well as trunked systems used by neighboring Clark County Washington and Washington County Oregon. Several fire and Emergency / Incident Command talk groups were utilized.

Wednesday brought in more federal agency response, and more activity on the 800 MHz systems. It did appear that there was use of the federal IWN VHF trunked radio system. I noticed a "spike" in the number of radios that were affiliated to the trunked system on Tuesday and Wednesday. Voice activity that I was able to catch on the IWN sites was all encrypted, so I can't confirm who exactly was using the system.

I did catch some conventional federal frequencies in use during the week. While near the area that the dirty bomb explosion was staged, I caught some simplex P-25 traffic on 167.3875 MHz, most likely FBI units on scene. While parked near the TOPOFF operations center in Portland, I did catch quite a bit of P-25 encrypted traffic on 138.225 MHz, most likely FEMA. They were a big presence at the ops center, as well as the Federal Protective Service. They were active on 417.2000 MHz, P-25 in the clear.

I am certain that there was more activity going on the federal bands, but I wasn't able to catch it. I'm also surprised that there was not more activity on any of the federal interoperability channels. I thought that this exercise might be a good time to catch some interop between the local 800 MHz trunked systems and some federal channels, but didn't catch any.

An interesting side note - I have seen no postings or any information on line about the TOP OFF exercises in Phoenix or in Guam. I don't know how many listeners there might have been in Guam, but I'm suprised that no one heard any of the events in Phoenix I'll have more in a future Fed Files column...

TOPOFF 4 Exercise Unfolds

I had a chance to do some monitoring and observations of the TOPOFF 4 exercise in the Portland, Oregon area this week and thought I would post some information.

The events started Tuesday, with the simulated explosion of a dirty bomb in downtown Portland on the Steel Bridge. The staged event took place on a simulated bridge with wrecked cars and a bus, all located at the Portland International Raceway along I-5 north of town. They had a large compound of tents and support vehicles for this event, but they kept the gawkers away by prohibiting any parking where you could sit and watch.

The radio traffic on Tuesday was primarily local public safety first-responders. Lots of active talk-groups on the Portland area 800 MHz trunked system carried traffic from this simulation.

The activities on Wednesday focused on recovery, decontamination and criminal investigation of the event. Lots of federal and military presence during the exercise on Wednesday. Some EPA air monitoring vehicles were staged at the Portland airport. Several very interesting FEMA vehicles were spotted around the city, including a mobile commmand post located at the TOPOFF Command Center, which was at the Doubletree Hotel in downtown Portland. Many DHS and military vehicles were parked around the hotel and clogged the entrance to the parking ramp. :-)

I'll update this blog with more info as I find it...

Oregon / Washington Army CoE

Thursday morning at home and just heard some radio checks on 163.4375 MHz, 100.0pl. One station requested a check on RANIER, which came in 5x5, then asked for a check on NASELLE, who came through not as well.

One op asked about some sort of check-in scheduled for Sunday. Also asked if they had the HF radio on. Original station said they did but that it was scanning the CoE frequencies.

The 163.4375 MHz repeater has been called "NAV Primary", and the input was noted as 164.2000 MHz.

DHS TOPOFF 4 Next Week

As you may have read on other lists or web sites, the DHS Exercise TOPOFF 4 will be held next week, October 15th through the 19th. More info can be found here:

http://www.dhs.gov/xprepresp/training/gc_1179350946764.shtm

http://www.dhs.gov/xprepresp/training/gc_1179430526487.shtm

http://www.dhs.gov/xprepresp/training/gc_1179422026237.shtm

The exercise will have "events" taking place in Phoenix, AZ, Portland, OR and in the US territory of Guam. These events will involve communications by first responders as well as government officials. This could be a good time to find out how the federal / local interoperability systems are working. The Guam location may provide some HF and SATCOM communciations as well.

NTIA Looks at 162-174 MHz

I recently came across this report on the NTIA (National Telecommunications and Information Administration) web site;

http://www.ntia.doc.gov/osmhome/reports/2006/land_mobile_DC_06_440.doc

It is an interesting look at the usage of the VHF federal band (162 - 174 MHz) in the Washington DC area. It talks about the different agencies that are using frequencies in this band and how many users there are. It also looks at the potential impact the Justice IWN trunked system will have on frequency loading in the area. Some of the report is very technical, and there are some frequencies mentioned.

Some additonal interesting reading can be found here;

Federal VHF Low Band - TVA?

A couple of years ago I asked MT readers for any information on current federal (non-military) agencies that are still using VHF low-band (30-50 MHz). Unfortunately I did not receive any information, but I recently stumbled across some discussions on Radio Reference about line crews from the Tennessee Valley Authority, (http://www.tva.gov/) still using low band.

Here are the TVA Lo-Band channels and locations that I have in my database:

38.97 - AL, MS, US
38.98 - AL, KY, MS, NC, TN, US
40.50 - KY, MS, TN, US
40.57 - US
40.61 - US
40.62 - AL, KY, MS, NC, TN, US
40.73 - US
40.74 - AL, KY, MS, NC, TN,US
40.75 - US
40.85 - US
40.87 - MS, US

Can anyone in the states listed give these a listen and let us know if they are active?

FPS Chicago & Other Cities

I have received word that the Federal Protective Service (FPS), a division of the Department of Homeland Security under Immigrations & Customs Enforcement (ICE) has changed frequencies.

406.7000 MHz, P-25 with no encryption, with an input of 415.7000 MHz, now seems to be the primary FPS channel in Chicago. The old analog repeater on 415.2000 MHz appears to be no longer in use.

UPDATE! - Both Cleveland and Toledo, OH have recently switched from 415.2000 MHz to 407.0000 MHz, P-25. Minneapolis, MN also reports that FPS has changed from 415.2000 MHz to 407.0000 MHz, P-25 within the last month.

Look for additional changes in the UHF federal bands as the NTIA band re-shuffling continues.

JENA Aircraft in Tampa FL

While listening to Tampa International (KTPA) approach on 08/28, I caught one of the controllers talking to JENA 32. At one point the controller called JENA 32 several times with no response, but JENA 024 ("Zero-Two-Four") came up and advised he was working with JENA 32 "on another radio" and he would pass along the instructions. The TPA approach controller just wanted to advise the JENA aircraft not to stray any further west as they would get mixed up with departing Tampa traffic. JENA 024 also advised TPA that they were trying to get JENA 32 on a target, then JENA 024 would depart the area.

Unfortunately I was not able to find what frequency the other radio might have been on.

Reports are that the "JENA" (here it was pronounced JENN-AH) aircraft are FBI operations using non-FBI pilots. The "ROSS" FBI aircraft call sign is still being used, and is reported to indicate that an FBI pilot is in command.

UPDATE!

Searching the Internet produced this video on YouTube:

http://www.youtube.com/watch?v=kldMbyNLXpM

The poster claims this is a military contractor flight landing at DCA and was using the call sign "JENA 611". Could the JENA flights heard on surveillance operations be DoD contractor pilots working FBI aircraft???

"VIPR" Airport Security Program

Local media is reporting an increase of federal law enforcement presence at the Portland International Airport (PDX) as part of a TSA program called VIPR. The program includes ramped-up security operations at randomly chosen airports and other facilities.

VIPR, standing for Visible Intermodal Protection and Response, has conducted missions at various events and transportation facilities over the last 18 months. The teams include canine teams, Transportation Security officers trained in behavior observation, air marshal supervisors, air marshals not scheduled for flights, surface transportation security inspectors and local police.

A quick search of the TSA web site (http://www.tsa.gov/) shows quite a few news releases on the VIPR program

VIPR Teams were also in Portland for the Rose Festival back in July, but local media did not report on this.

No specific communications frequencies have been noted, but increased traffic (encrypted) on the Justice IWN trunked system here in Portland may be a result of this operation.

More as it becomes available...

VHF EDACS Mystery Solved!?

It appears that our mystery VHF EDACS trunked radio system mentioned in a previous blog entry has been located. Someone tracked down the control channels on 173.4250 MHz and 170.7625 MHz, and they appear to be coming from the NASA Goddard Flight Facility at Wallops Island, VA:

http://www.nasa.gov/centers/wallops/home/index.html

The NASA web site does not mention this trunked system specifically, but there are some interesting downloads containing information about the range and it's facilities:

http://www.nasa.gov/centers/wallops/multimedia/index.html

The information about the location of these control channels also indicated that NASA security there continues to utilize their VHF conventional repeaters on 170.0000 MHz and 171.1500 MHz. A quick look at previously monitored frequencies at Wallops Island seems to show a lot of VHF usage in the same area as these trunked systems:

http://www.monitoringtimes.com/html/Monitoring%20NASA%20and%20Space%20Communications.pdf

We'll try and track down more information on this new trunked system and pass it along in a future Fed Files.

VHF Trunking Mysteries

There are a couple of mysterious trunking control channels that have been reported in the VHF federal bands and so far we have no solid information on where they are coming from or who is operating them.

First, a listener in New Jersey as been reporting what he believes is an EDACS trunking control channel on 170.7625 MHz. 172.6875 & 172.9875 MHz might be analog voice channels associated with this control channel. The signal comes and goes as if it's being heard via skip, but from which direction is unknown. EDACS federal trunked systems are rare, but a VHF system would be a first. Listeners in Philadelphia, where 170.7625 MHz is used as by DHS/ICE have not confirmed a trunked system there. The 172.6875 and 172.9875 are previously un-assigned frequencies.

The originator of this information has theorized that it's an ICE/DHS trunked system somewhere. But so far he hasn't reported any specific voice traffic heard. I find that difficult to accept with as little information as we have so far. It makes no sense to me that the DHS would set up an analog EDACS trunked system, totally incompatible with what they are doing everywhere else, and not using the P-25 standard, which has been mandated by specifications in federal budgets for interoperability.

In the south, another monitor in Florida is reporting a P-25 control channel on 170.1250 MHz. It is reporting a System ID of 910. Speculation is that it might be military or Department of Energy, but nothing is confirmed. This signal is also being heard via skip from an unknown location in the Southeast US.

Anyone else hear any of these signals? Let us know at the Fed Files!

New CBP A&M Units?

I've been receiving information that there is a new call sign being heard on some of the Customs & Border Protection radio nets in the Southwest US. Listeners in Arizona have started reporting references to "1100 TAC" units, sometimes in association with CBP air units. The call sign does not appear to refer to a base location or station, but mobiles that operate as a group under that call. Sounds like it could be a Task Force unit of some kind, perhaps National Guard units working along the border?

Also, the CBP division that we used to refer to as Air Marine Interdiction Division (AMID) is now simply Air & Marine:

http://www.cbp.gov/xp/cgov/border_security/air_marine/cbp_air_marine_overview.xml

And it appears that the CBP A&M has added two AgustaWestland AW139 helicopters to its aircraft fleet:

DoE / BPA Activity

The Bonneville Power Administration, headquartered in Portland, Oregon, is an agency under the U.S. Department of Energy. They operate a series of VHF repeaters in the Pacific Northwest that is normally used for transmission line and facilities maintenance. All of these repeaters operate on 172.5250 MHz.

Recently I caught a transmission from "KOD900 Denver" calling an aircraft (who's call sign I failed to catch) about his landing at Portland Internatnional Airport. I assumed that the aircraft was probably involved in aerial inspections of tranmission lines. I also had not realised that BPA had a centralized dispatch center that was NOT in Portland!

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!
