October 2014 Federal Wavelengths Correction

A sharp-eyed reader just brought it to me attention that there were a couple of errors in my listing of the frequencies used by the Environmental Protection Agency (EPA) in the October issue of The Spectrum Monitor magazine.

By all means, if you spot something with any frequency lists either here on the Fed Files blog page or in the pages of The Spectrum Monitor magazine, please feel free to let us know about it.

Here is the corrected list showing the correct EPA repeater input and output frequencies:


ZONE 2 – EPA Repeaters



Repeater Output   Repeater Input    Channel Name
173.8750, D731    166.4750, D731    EPA REPEATER

170.9750, CSQ     168.7000, CSQ     NI/CG REPEATER 1

170.4500, CSQ     168.1000, CSQ     NI/CG REPEATER 2

170.4250, CSQ     168.0750, CSQ     NI/CG REPEATER 3

168.4000, CSQ     166.6125, CSQ     NI/CG REPEATER 4

169.7500, CSQ     167.1000, CSQ     NI/CG REPEATER 5

173.8125, CSQ     168.4750, CSQ     NI/CG REPEATER 6

170.9750, CSQ                       NI/CG SIMPLEX 1           

170.4500, CSQ                       NI/CG SIMPLEX 2

168.4000, CSQ                       NI/CG SIMPLEX 4

169.7500, CSQ                       NI/CG SIMPLEX 5

173.8125, CSQ                       NI/CG SIMPLEX 6

South Florida FPS Changes

In addition to the upgrades to the Customs and Border Protection (CBP) radio network in Florida, it appears that the Federal Protective Service (FPS) has also upgraded to P25 digital.

410.8 MHz, N201 is now being used by the FPS in the Miami area. The same frequency is most likely used through out this FPS region. Some sites may have different NAC's.

You can read more about the CBP upgrades and frequency changes in the latest edition of The Spectrum Monitor, http://www.thespectrummonitor.com/index.aspx

CDC Frequencies

Some questions regarding the use of radios by the Centers For Disease Control and Prevention (CDC) have been posted in regards to the confirmation of Ebola in the Dallas, Texas area.

I know that the CDC uses federal UHF trunking at their fixed facilities around the Atlanta area. But a while back I posted possible CDC field use frequencies that might have been in use for the Swine Flu outbreak:

Email Apologies To All

To anyone and everyone who might have been sending me emails to the chrisparris@thefedfiles.com address - I realized that I have not been seeing any emails from that address for a while and just assumed no one was sending me anything. But a Fed Files fan on Twitter asked about an email he sent that I hadn't seen on any of my computers or email devices. I discovered that my emails were just sitting there and I wasn't seeing them. I've been trying to catch up on these as I can. 

Please continue to use this email address for future communications: chrisparris@thefedfiles.com

CBP Florida Makes The P25 Switch

Over the last couple of years I have heard that the CBP was coordinating and installing new P25 digital gear in the state of Florida.

I just spotted a post on Radio Reference that indicates the Customs and Border Protection radio systems in Florida have finally moved towards the digital domain after being analog for many years:

http://forums.radioreference.com/federal-monitoring-forum/297786-news-flash-florida-bp-throws-p25-switch.html

There are what appear to be some of the new CBP DNET channels in the +170 MHz end of the band, so I will list them as they can be ID'd in the CBP Frequency Update area on the blog main page.

Air Force One Phone Systems

An interesting post has appeared on line about the new phone systems in use aboard Air Force One. It's an interesting read:

There is also an story on something I've always wondered about, how they got a secured Blackberry for President Obama:

NIFC NATIONAL AIR-TO-GROUND FREQUENCIES

The National Interagency Fire Center maintains a standard issue of nationwide air-to-ground (A/G) channels for use in firefighting and other incidents on federal lands. I have been asked for some time if I had the complete list of these A/G channels, so I decided to sit down and go through all the materials I had access to and see if I could come up with a good list.

What I discovered is that there are some variations of these A/G frequencies, and even some official US government publications don't agree. So keep in mind that this list is not cast in stone, but may have some variations...
