Mall in Columbia Updates Frequencies

The Mall in Columbia recently modified its license. Repeaters on 461.4500 and 464.1250 were added to the previously licensed repeater on 464.8750.

The mall has been monitored using an unlicensed repeater on 461.1125; this has probably been replaced by these newer frequencies.

Verizon Center Moves to Capacity Plus, Enables Privacy

The Verizon Center is now using a three-frequency MOTOTRBO Capacity Plus system. The groups monitored (102, 109, 111) were using Privacy. The system also appears to have Restricted Access to System (RAS) turned on. This means that only authorized radios can transmit or receive on the system. (This does not affect the operation of DMRDecode or DSD, but there is nothing to monitor with DSD anyway because Privacy is enabled.)

The other 461 MHz frequencies previously in use are being used as MOTOTRBO conventional repeaters. All groups on these frequencies are also using Privacy:

461.0750 [         ] (MOTOTRBO - Color Code 4, Slot 1, Group 101) (privacy)
461.0750 [         ] (MOTOTRBO - Color Code 4, Slot 2, Group 105) (privacy)
461.1000 [         ] (MOTOTRBO - Color Code 11)
461.1750 [         ] (MOTOTRBO - Color Code 10)
461.5250 [         ] (MOTOTRBO - Color Code 8, Slot 1, Group 103) (privacy)
461.5250 [         ] (MOTOTRBO - Color Code 8, Slot 2, Group 104) (privacy)
461.6000 [         ] (MOTOTRBO - Color Code 9, Slot 2, Group 108) (privacy)

(461.1000 and 461.1750 did not have voice transmissions on them when I monitored, but I was able to obtain color codes from brief data transmissions.)

Security personnel appeared to be using XPR7550 radios.

The Verizon Center has an application pending for the Capacity Plus system; the rest of the frequencies are covered under an older license (which doesn't have emission designators for MOTOTRBO).

Jefferson Hotel Using Capacity Plus System

The Jefferson Hotel is using a MOTOTRBO Capacity Plus trunked system. During the time I monitored, only two groups were found, but there may be more. (Only one group is listed on RadioReference, because I was unable to confirm a definite use for the other.)

No activity was monitored on the hotel's two previously-confirmed MOTOTRBO simplex frequencies (456.4625 and 462.3500), but they may still be in use.

Miscellaneous Downtown DC Finds

Here are a few frequencies found yesterday in downtown DC:

467.8750 [100.0] Marshalls

DSD+ Program Released

A "new" version of the Digital Speech Decoder (DSD) program has been released in the last few days. DSD+, which is separate from DSD, provides much better audio decoding. The program also allows for selecting input/output. There is a RadioReference thread about DSD+ here.

DSD and DSD+ allow one to decode Project 25, DMR/MOTOTRBO, and NXDN audio. The latter two formats cannot be decoded by scanners.

The Westin previously used 464.8250 [254.1] for housekeeping, but I heard someone calling for engineering on the frequency yesterday.

452.5250 [ 82.5] (S) was monitored, and sounds like it may be a hotel.

NSWC Dahlgren Changes LTR System

The LTR system used by the Naval Surface Warfare Center, Dahlgren Division has changed frequencies. All talkgroups still appear to use voice inversion.

Interestingly, a guard was observed at the main gate yesterday, and he appeared to have a UHF handheld radio, possibly manufactured by Harris. This radio would probably operate on the Joint National Capital Region system, but Dahlgren's site on the system continues to only broadcast traffic for other installations in the region, such as NSWC Indian Head and Patuxent Naval Air Station.

DCFD Encrypting in Early 2014?

DC Fire may encrypt their communications in early 2014, according to a post on Scan-DC. The switch to encryption may coincide with DC Fire's adoption of APX radios when they transition from the Project 16 system to the Project 25 system.

Metropolitan Police are already on the Project 25 system, and most of their communications are encrypted, with the notable exception of the Citywide 1 talkgroup.

Costco FCC License

Costco, located at 4725 West Ox Rd. in Fairfax, was recently licensed for a repeater on 152.3300.

Uniden Announces New Scanners

Uniden announced two new scanner models today. The handheld model is called the BCD436HP, and the base/mobile model is called the BCD536HP. Both will be able to monitor Project 25 Phase II communications, like the PSR-800. The models borrow much of the technology and features of the HomePatrol, including a 4 GB SD card for RadioReference database storage and audio recording, Discovery and Analysis modes, and USB connectivity.

Information on the new models, including a user manual and programming software, is available at Uniden. (The site is often slow and unresponsive; one may have better luck looking for info on RadioReference.)

The scanners should be available for purchase in January. The BCD436HP is expected to retail for about $500, and the BCD536HP for about $600.

Union Station FCC App

Redskins Game Tonight

The Washington Redskins open their season tonight at 6:55 at FedEx Field. Here are some monitoring suggestions:
Other frequencies monitored previously at FedEx Field can be found on the Prince George's County page. With a decent antenna, it may be possible to monitor the LTR system and the UHF conventional repeaters from some distance away from the stadium; I monitored them from downtown Washington last year.

ESPN is televising the game, so their frequencies may be active. From previous events, I suspect they use 464.5000 and 464.6500.

UVA Football Game Finds

Here are talkgroups found on the Charlottesville/Albemarle trunked system for Saturday's University of Virginia football game:

42384 University Transit Service Emergency
43168 Charlottesville School Buses 1 (Shuttles)
43536 University of Virginia Emergency Management 1

(Thanks to mountaintop transmitters, I am just able to copy the system from Fredericksburg. Receiving the system from Northern Virginia might be more difficult, as Fairfax County shares several frequencies with Charlottesville/Albemarle.)

Shops at Union Station Changes Security Frequency

The primary security frequency for the Shops at Union Station has changed to 464.5250 [ d311] from 464.5750 [ d346]. It's possible 464.5750 was receiving interference from Catholic University, which uses MOTOTRBO on the frequency.

Friday, August 30, 2013

Stafford Sheriff Unencrypted Talkgroup

Charles County Schools MOTOTRBO Update

Charles County Schools may be doing testing on their MOTOTRBO system. Yesterday, 152.9825 had MOTOTRBO on it, but it appeared to be conventional MOTOTRBO, not Capacity Plus or Connect Plus. Perhaps the radio techs are testing the system in conventional mode before "turning on" the trunked system. (From my location in Fredericksburg, I am too far away for DSD and DMRDecode to decode the data.)

Holiday Inn College Park FCC App

The Holiday Inn College Park has an application pending before the FCC. The app calls for simplex on 452.1875, 452.2875, 456.4375, 456.6875, and 456.7375. The frequencies are coded for both analog and MOTOTRBO.

Aeronautical Radio (IAD) Capacity Plus

Aeronautical Radio has a MOTOTRBO Capacity Plus system running at Dulles Airport. I mapped out the system today, but it appears all the groups are using Privacy. That's unfortunate, as there are probably several airlines using the system.

STARS Dumfries Active

The STARS Dumfries site has been active with talkgroups for at least a couple of weeks. The most common talkgroups seen are the VSP Fairfax channels, but I've also seen a VSP Culpeper talkgroup and a Corrections talkgroup. Since this is a "filler" site, the range is limited, but it's certainly welcome for those in the immediate area.

American University MOTOTRBO Capacity Plus System

American University's MOTOTRBO Capacity Plus system is active. At least two sites are on the air. I didn't do much monitoring of the groups in the system, but I noticed one (203) was using Privacy. It's unknown if the whole system is using Privacy, or if only select groups are.

The University has an application to its license to add another two-frequency site. There is also another license.

FleetTalk MOTOTRBO Connect Plus System

FleetTalk has moved to replace their LTR/PassPort systems with a MOTOTRBO Connect Plus system in the Washington area. From Tysons Corner, I was able to monitor three of the sites (Upper Marlboro, Silver Spring, and Falls Church). The users appear to be many of the same ones who previously used the LTR/PassPort systems, as well as users who needed a radio solution after the shutdown of the Nextel network. ID 30007 is a traffic reporting service, and some of its mobile units were commenting on the quality of the system as they drove around downtown DC yesterday. This ID may be Traffic.com, as they were a user on the Silver Spring LTR site.

Fairfax Schools Switch to MOTOTRBO

Many Fairfax County Schools have switched to MOTOTRBO on their internal VHF frequencies. These are the frequencies that are used for personnel inside the schools, not for schools buses and maintenance personnel.

The hospital recently renewed its license for 463.7500, so this frequency will probably continue to be used in addition to the frequencies requested in the application.

451.5125 [         ] Primary (MOTOTRBO - Color Code 1, Slot 1, Group 1) (R)
452.7125 [         ] "Private" (MOTOTRBO - Color Code 1, Slot 1, Group 3) (R)

Interestingly, the license for the two MOTOTRBO channels does not indicate that they are digital, nor does it indicate that they are repeaters.

Pentagon City/Crystal City Hotels

A few new frequencies for hotels in Pentagon City and Crystal City:

456.7125 [ d506] Crystal Gateway Marriott
151.8650 [107.2] Doubletree Crystal City - Security (S)
465.3125 [241.8] Sheraton Crystal City

Arlington Talkgroup 76

Last week, talkgroup 76 on the Arlington Country trunked system was monitored. References were made to "RM1" and a "fire marshal." It sounded like the people talking were coordinating response to a fire alarm.

This talkgroup hasn't been seen before, and falls slightly before the local government talkgroups.

452.1125 [ d131]

452.1125 [ d131] (R) was noted in use several times last week. It appeared to be a temporary frequency for coordinating transportation/shuttles for an event. The people using it made reference to a "production trailer," "talent," and "Mandarin Oriental." I thought it may have been used for the Smithsonian Folklife Festival, but I monitored communications on Tuesday of last week, a day the festival was closed.

This frequency/tone was in use at this year's Cherry Blossom Festival Parade, and at the Convention Center during the Inaugural Balls, so it seems likely that it's a repeater set up by a radio rental company.

STARS Dumfries Tower Progress

The STARS tower at the Dumfries truck weigh station appears to be nearing completion. The tower number and frequencies have been added to the RadioReference STARS page. When this tower comes online, it should improve communication greatly in Prince William and Stafford, where there have been issues with reception of STARS.

Convention Center Update

I monitored the Walter E. Washington Convention Center MOTOTRBO Capacity Plus system during an event yesterday, and identified some of the groups. I believe I also saw groups 8 and 11 in use, but I could not identify them. It appears that various contractors for the Convention Center have their own groups on the system.

The license never indicated a trunked system, so Greenspring is now operating according to the license.

Convention Center Switches to MOTOTRBO

The Walter E. Washington Convention Center has switched to a MOTOTRBO Capacity Plus trunked system. A few groups (1, 3, 4) were seen, but no identifications were made.

The convention center's license has not been updated to reflect the new system; in fact, the license does not even indicate that the frequencies are used as repeaters.

453.9875 (Color Code 10) was active, but it may be used as a MOTOTRBO conventional repeater.

Willard Intercontinental Using MOTOTRBO

The Willard Intercontinental Hotel is using MOTOTRBO, even though their application has not been approved yet.

United Medical Center FCC App

United Medical Center, located at 1310 Southern Ave. SE in DC, has an application to its license pending before the FCC. The app calls for a repeater on 461.7875. The repeater is listed with an analog emission designator, but the hospital currently uses MOTOTRBO on 464.8250, so it wouldn't be surprising to see MOTOTRBO on this frequency as well.

Baltimore Major Update

Took a trip to Baltimore last Saturday, and updated many frequencies on the Baltimore page. Some observations:
  • Johns Hopkins University continues to migrate to MOTOTRBO. Interestingly, they seem to use Color Code 5, Slot 2, Group 40 on many of their frequencies.
  • The frequencies used by the Maryland Stadium Authority and Oriole Park at Camden Yards remain analog. (The licenses had the MOTOTRBO emission designators added to them recently.)
  • The National Aquarium MOTOTRBO Capacity Plus system is somewhat hard to figure. DMRDecode reports the same LCN for 464.4750 and 464.8250.
  • Harborplace uses three UHF repeaters, but they all seem to have security traffic on them at one point or another. They may have a separate frequency for each part of the complex (Pratt St. Pavillion, Light St. Pavillion, and Gallery at Harborplace).
  • The Hotel Monaco is using frequencies that are still in the application process.
  • The Hyatt Regency has switched to MOTOTRBO.
  • The Marriott Inner Harbor at Camden Yards is finally using their frequencies.

Unknown MOTOTRBO in Tysons Corner Area

Here are some unknown MOTOTRBO frequencies monitored in the Tysons Corner area:

463.2125 [         ] Rockwell Collins or Jewish Federation of Greater Washington (MOTOTRBO - Color Code 12, Slot 1, Group 1000)
463.5375 [         ] Suburban Hospital? (MOTOTRBO - Color Code 5, Slot 2, Group 202)
463.5875 [         ] Verisign or Norwood School (MOTOTRBO - Color Code 3, Slot 1, Group 1)
463.7750 [         ] Charles E. Smith - Reston? (MOTOTRBO - Color Code 1, Slot 1, Group 13)

MOTOTRBO Connect Plus Systems

FleetTalk Partners appears to be converting their LTR/LTR PassPort systems to MOTOTRBO Connect Plus systems. Here are some frequencies monitored from the Crystal City/Pentagon City area:
  • 495.9625 - Connect Plus control channel; strong signal. Originates from Silver Spring. RadioReference page.
  • 496.2125 - Probable MOTOTRBO voice channel; strong signal. May originate from Falls Church or Silver Spring.
  • 496.6625 - Connect Plus control channel; weak signal. May originate from Waldorf, Independent Hill, Upper Marlboro, or Falls Church.
I did not run DMRDecode on the frequencies, so I don't have information on system IDs, sites, etc.
