Luke AFB Migrates to 380 MHz P25 System

According to recent postings on Radio Reference, the trunked radio system at Luke Air Force Base in Glendale, Arizona has changed frequencies. The system moved from being in the 400 MHz federal band to the 380 MHz DoD managed spectrum.

One listener posted the control channel data he had deciphered: 
SYS:3D6
WACN:BEE00
SITE NAC:3DE

RFSS-SITE:01-0E

385.0375
385.7625
385.9750
386.2500
386.5000
386.9750
387.4375
387.7875
387.9750
388.1500
388.3000
388.5750
 
The system ID and WACN indicate this is part of the larger US Air Force 3D6 networked trunked system, featuring VHF, UHF and 380 MHz systems. This system also serves multiple military bases in the San Antonio, Texas area:

Changes Coming for VHF Marine Channels

There are changes coming for the normal FM marine channels. The International Telecommunications Union has (ITU) has began re-numbering some of the international marine channels in anticipation of 12.5 KHz channels and digital modulation coming to the VHF marine band. You can read more about the changes here:

The US Coast Guard has some offerings that show some of the new marine VHF channel numbers:

More TSA Updates Pouring In

The TSA continues to make changes across the country as it upgrades their radios. They are definitely changing the input frequencies to the repeaters and changing Network Access Codes, or NAC's.

The changes to the input frequencies are likely being done to bring the radio systems in compliance with NTIA guidelines for VHF repeater pairing. Repeater inputs will be mainly in the lower region of the VHF federal band and the repeater outputs and simplex channels will be in the mid and upper portions.

I am continuing to update the TSA frequency page as I get new information. Please check back often for updates - http://mt-fedfiles.blogspot.com/p/tsa-frequency-updates.html

Uniden Announces DMR & ProVoice for 325P2 and 996P2

Uniden has announced that they will begin to offer paid upgrades to provide ProVoice and DMR digital modes to the 325P2 and 996P2 scanners.

http://info.uniden.com/twiki/bin/view/UnidenMan4/DigitalMobileRadioUpgradeforBCDxxxP2

The Uniden 435HP and 535HP radios have already been updated to receive ProVoice mode and DMR digital trunking modes with the paid updates. The release date for the upgrades for the 325P2 and 996P2 radios has not been announced. With the DMR upgrades for the 436 and 536 radios, you were allowed to pre-order the upgrade before it was released.

The big question now is when Uniden will began offering the NXDN upgrade following the release of a NXDN mode for the competing Whistler TRX series of radio scanners.
