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.

Phoenix Federal Scanning

Justice IWN Update - The Next Move?
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!

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:

170.9875 - CC
167.6125
168.8500
171.3250
171.4375
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.

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!
