Just released by the US Secret Service, here is the transportation plan for the upcoming Presidential Inauguration. The details in this document are mostly about street closures at various locations around the DC area. But it is interesting information for those who will brave the crowds to attend!

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.

RNC Security Information

The Secret Service has posted an interesting PDF file regarding all the security surrounding the RNC Convention in Cleveland. You can find that file here:

GAO Report on The Secret Service



I wrote about this report back in the April 2016 edition of The Spectrum Monitor:
-->
The report talks about various problems that have been noted with keeping US Secret Service communications and computer network systems up to date. Although there are several passages and items that are redacted in this copy of the report, there are some interesting items of note. For instance, OIG audits found that much of the Secret Service radio communications inventory is in need of replacement and soon. While radio operations are generally good, there have been instances of radio failures that could have led to serious problems. The report noted that Secret Service logs indicate about a 3% failure rate of radio transmissions. Much of the radio equipment is near or past it’s intended end-of-life and should be replaced. The report indicates that there are plans for radio system equipment to be replaced through 2019.

   An item that was redacted was mention of something that allows “voice communications within the Secret Service and for interoperability with law enforcement partners.” This could possibly be a radio system “bridge” that can link disparate radio systems and allows seamless communications without modifying the agency radios. It also might also refer to encryption keys or key management systems.

Changes in San Antonio Military Systems

Over the past few weeks I've been seeing reports on the Radio Reference forums of some changes occuring in the UHF trunked systems used by the various military bases and facilites in the San Antonio, Texas area. These facilities include Fort Sam Houston, Kelly, Randolph and Lackland Air Force Base and Camp Bullis, northwest of San Antonio.

Previously, the various military facilities had been sharing a Motorola Type II trunking system. The various bases are now migrating towards a new APCO P-25 Phase II digital system. The new system is showing a System ID of 3D6 and is showing it is capable of Phase II TDMA operation, but I've not confirmed that Phase II operation is actually taking place. A number of new military UHF trunked systems are advertising that they are TDMA capable, but the users are not necessarily using that feature yet.

This system is showing that it is networked with other US Air Force bases around the country. Here is a link to the new sites and frequencies in use:
