New BCD436HP Firmware Released

Yesterday, Uniden released a major firmware update for the BCD436HP scanner. This is the first firmware release since March of last year, when a minor maintenance release was issued. The firmware adds the "Analyze" feature, displays Close Call hits immediately (without prompt for a key press), speeds up conventional scanning, and provides a workaround for a failing real-time clock battery. Users have also reported that P25 reception has been improved.

The firmware update follows a similar update (released April 10th) for the BCD536HP.

DCFD ELO - Channels A13/A14

DC Fire has a mix of clear and encrypted channels on the DC P25 system. The 0 zone is in the clear, and the A/B/C zones are encrypted. Often, medics will call the ELO (EMS Liaison Officer) on channel 013, and are told to switch to A13. This indicates A13 is for the ELO, although the talkgroup number is unknown. (The mix-up also occurs on 014, and medics are told to switch to A14, which is another encrypted ELO talkgroup.)

DC FedSMR Update

With the DC FedSMR transitioning from Passport to IDAS, I checked some of the frequencies for activity on Saturday from downtown. 406.5875 had IDAS data bursts on it. 408.5500 still has Passport data bursts every couple of seconds. 409.8500 had IDAS data bursts, as well as what appeared to be voice traffic. The traffic was not decoded by DSD+, so it may be encrypted. 410.3125 had IDAS data bursts, but they didn't seem to be as strong as those on 406.5875 and 409.8500.

Sakura Matsuri Finds

Here's what I found at Saturday's Sakura Matsuri Japanese Street Festival:

452.4875 [ d412] (S)
452.8625 [ d412] (S)
DC Fire used talkgroup 717 (Special Events 2).

The two UHF simplex frequencies were also used in 2013, the last year the festival was monitored.

Cherry Blossom Parade Finds

Here's what I found at Saturday's National Cherry Blossom Festival Parade:

461.0375 [         ] Organizers (DMR - Color Code 1, Slot 1, Group 5004) (S)
461.0625 [         ] Organizers (DMR - Color Code 1, Slot 1, Group 5005) (S)
461.2375 [         ] Organizers (DMR - Color Code 1, Slot 1, Group 5001) (S)
461.4375 [ d152] CSC Event Staff (S)
DC Fire used talkgroup 717 (Special Events 2). DC EMA used talkgroup 2117.

CSC Event Staff had MOTOTRBO radios, but were using their frequency in analog mode.

Organizers had several more channels available than the three I found. According to information found about the radio zones, the event used two zones. One was comprised of two "citywide" channels, which were probably repeaters, and may have been leased channels on a DMR trunked system, such as the FleetTalk Partners system. The other zone was comprised of eight (simplex?) channels.

Zone 1:
Event Ops - City Wide
TV - City Wide

Zone 2:
15th Street

RINS/COG Frequencies Active

In the past few days, a couple of the Regional Intersystem/Council of Governments frequencies have been active. These are 800 MHz frequencies primarily used for interoperability in the DC area. 852.2375 [192.8] was active in Fredericksburg. 852.4875 [ 91.5] was monitored on I-95 near Potomac Mills. The units talking on this frequency may have been from Maryland. The conversations were brief; specific users could not be identified.

Mount Vernon 452.3875 Switched to NXDN?

Mount Vernon's 452.3875 frequency may have switched to NXDN. The digital format was heard near the estate, and no other licenses for the frequency are in proximity. The license has not been modified for digital; it still indicates analog voice.

Holocaust Museum Switches to Capacity Plus

The United States Holocaust Memorial Museum is now using a MOTOTRBO Capacity Plus system. The museum was previously using the DC Area Federal SMR system. With that system being converted to an IDAS system, it was evidently decided to take a couple of frequencies from it and devote them to the museum.

Omni Shoreham Hotel Using Capacity Plus

The Omni Shoreham Hotel in DC is using a MOTOTRBO Capacity Plus system. In brief monitoring, only one talkgroup was identified, but two others were seen (104, 105).
