Marriott Marquis Switches to Capacity Plus

The Marriott Marquis Hotel in DC has at least partially switched to a Capacity Plus system. The three frequencies used for this system are able to be monitored from many points in DC and the surrounding area. The hotel is licensed for several other frequencies, which are only able to be monitored in the vicinity of the hotel. These have previously been confirmed to be DMR conventional, and it's not known if these frequencies were switched to Capacity Plus as well. It's possible the hotel has set up a Linked Capacity Plus system. (The hotel needs multiple frequencies to carry the same traffic because it has several below-ground levels.)

The Capacity Plus system has Restricted Access to System (RAS) enabled, which means a DMR radio cannot be programmed to monitor the system. The system can be monitored with a program such as DSD+, however.

Citi Open Finds

Here's what was monitored at the Citi Open yesterday:

461.0375 1-1004 "credentials"
461.0875 1-1006

461.1375 1-1008
461.1625 1-1009
461.2375 1-1001 Tournament Officials
461.2625 1-1002 Operations
461.2625 1-1011 Tournament official talking to doctor
466.0375 1-1003 Security (Ch. 3)
466.0875 1-1013 Announcement Rehearsal
466.1125 1-1014

461.2375 1-3001 Parking

166.8500 [127.3] Park Police (S)
461.5500 [  88.5] CES Security (S)
464.3250 [ d532] Design Cuisine (S)
464.5000 [123.0] TV (S)

The tournament was using DMR simplex this year. In 2013 (last year monitored), officials used UHF analog simplex. For the top set of frequencies, the first number is the color code, and the second number is the group.

The tournament continues through Sunday.

Weekend Events

  • The Nationals play Friday at 7:05, Saturday at 7:05, and Sunday at 1:35 at Nationals Park.
  • The Citi Open continues through Sunday at the Fitzgerald Tennis Center in Rock Creek Park.

Nationals Park Switches to Capacity Plus

Nationals Park has switched from conventional DMR to a Capacity Plus system. The ballpark appears to only be using four of the six licensed repeaters, but this yields a capacity of eight talk-paths. During my limited time monitoring, a few groups were identified, but there are several others in use. (The "cash room" was mentioned to use Channel 8.)

The license has not been updated to account for the trunked system.

National Harbor Update

Here are some updates for National Harbor:

462.0875 [         ] Capital Wheel (DMR - Color Code 4, Group 7) (S)
464.8250 [ d351] AC Hotel - Housekeeping (S)
467.9250 [ d351] AC Hotel - Engineering
154.5700 [  67.0] Residence Inn by Marriott

The Capital Wheel has switched from repeater to simplex operation, and is using a different frequency and group. The AC Hotel is using one of the frequencies from its license. The Residence Inn is using the VHF frequency even though the hotel's license for UHF frequencies remains valid. The hotel may also be using 462.5875. The Hampton Inn is using digital (probably DMR) simplex UHF portables. The frequency was not found, and I did not see the brand of radios they were using.

I also updated a couple of groups for the Gaylord National Hotel system.

Unknown Capacity Plus System

I monitored an unknown Capacity Plus system yesterday from National Harbor. It appeared to use a single frequency, 462.0375. The color code was 3. One group was noted: 5. On this group, "kitchen," "third floor," "Springfield Mall area," and "admin office" were monitored.

None of the FCC licenses for the frequency seem to make sense for what I was hearing.

National Harbor Simplex Frequencies

While at National Harbor yesterday, I monitored several DMR simplex frequencies. I suspect these are in use for the construction of the MGM casino, which opens in the second half of 2016. (The first number after the frequency is the color code, the second the slot, and the third the group.)

451.4625 9-1-1
451.4875 10-1-1
451.5625 10-1-1
451.5875 11-1-1

Goodwin House FCC App

Goodwin House, a retirement community in Alexandria, has an application pending before the FCC for repeaters on 461.4750 and 461.6500, and simplex on 464.4750.

Spotsylvania P25 Phase II System FCC App

Spotsylvania County, which will be upgrading from an EDACS system to a Project 25 Phase II system, has an application before the FCC. The app calls for four eight-frequency repeater sites. (Two of the frequencies will be returned once the system becomes operational.)

The county seeks to build a ten-site system with six frequencies. Because the Phase II system will use two-slot TDMA, the system should have ten voice paths available at any given time. (One of the frequencies will be used as a control channel, and there are two voice slots on the remaining five frequencies.) The current EDACS system also has ten available voice frequencies.

The county also has an application pending to modify its existing license to add four sites.

Quicken Loans National Temp License

Creative Communications was recently licensed for several UHF DMR frequencies to be used at the Quicken Loans National golf tournament (July 30-August 2 at Robert Trent Jones Golf Course in Gainesville, VA).

Folklife Festival Frequency Found

The Smithsonian Folklife Festival was confirmed using 412.9000 (NXDN 4800 - RAN 42, Group 23, Scrambled). Because the frequency is scrambled, it cannot be monitored even with a program like DSD+. This frequency does not appear to be part of the DC Federal SMR.

Spotsylvania Sheriff Radio IDs

Spotsylvania Sheriff appears to use IDs for mobile radios that contain the vehicle number. For example, vehicle 278 uses a radio ID of 10278. The format appears to be 10xxx, where xxx is the vehicle number. The portable radios are in the format 2xxx, where xxx is the unit ID of the transmitting unit. Therefore, portable radios will always identify the deputy's unit number, but mobile radio IDs will only identify the vehicle (because multiple deputies use the same vehicle at different times).

Virginia Emergency Management Using Some Encryption

The Virginia Department of Emergency Management "Red" talkgroups on STARS are now encrypted full-time.

Udvar-Hazy Center Using NXDN

The Udvar-Hazy Center at Dulles Airport has migrated to the DC Area Federal NXDN IDAS system. Three frequencies were found, and the site was showing as Site 4. All transmissions appeared to be scrambled.

Dulles Airport Update

Here are new/updated frequencies for Dulles Airport:

451.8500 [         ] Skycaps (Huntleigh) (DMR - Color Code 10, Slot 2, Group 3) (RAS)
464.9000 [         ] Skycaps (Huntleigh) (DMR - Color Code 1, Slot 1, Group 22151) (RAS)
452.2250 [         ] Alaska (DMR - Color Code 2, Slot 1, Group 101)
460.7875 [         ] Avianca/Taca (DMR - Color Code 1, Slot 1, Group 1)
460.7875 [         ] Avianca/Taca (DMR - Color Code 1, Slot 2)
460.7625 [         ] Southwest (DMR - Color Code 12, Slot 1, Group 101)
460.7625 [         ] Southwest (DMR - Color Code 12, Slot 2, Group 102)
460.8750 [         ] US Airways/American (DMR - Color Code 1, Slot 1, Group 1001)
463.3250 [         ] Hertz - Customer Service (DMR - Color Code 9, Slot 1, Group 11)
463.3250 [         ] Hertz - Buses (DMR - Color Code 9, Slot 2, Slot 12)
452.2750 [         ] Swissport (DMR - Color Code 1, Slot 1, Group 1) (RAS)
452.2750 [         ] Swissport (DMR - Color Code 1, Slot 2, Group 2) (RAS)

Many of the above frequencies were previously analog, and have switched to DMR. The Hertz frequency may actually be for Dollar/Thrifty, since Hertz already has a separate frequency at the airport.

The Aeronautical Radio trunked system was found to have at least one unencrypted group; other groups are using Enhanced Privacy.

The United Airlines trunked system remains Motorola Type II; it was suspected that the system may have been converted to Capacity Plus or Connect Plus, as United seems to be doing with some of their systems at hub airports (such as Chicago) in the United States.

National Memorial Day Parade

Monitored via the DC trunked system software-defined radio, here are a couple of talkgroups active during today's National Memorial Day Parade:

717 DCFD Special Events 2
2117 DC Emergency Management Agency

Tysons Corner Center License Modification

Tysons Corner Center recently modified its license. DMR emissions codes were added to the 464.9375 repeater, and the 464.3750 repeater was added as DMR/analog. 464.9375 has never been used by the mall (the property has used an unlicensed repeater on 461.9875 for security for years). 464.3750 has been used by the mall for housekeeping, but may have been added to this license because the current license for the frequency is expiring next month.

Sunday, May 24, 2015

Capitol Crossing FCC App

Balfour Beatty Construction, which is constructing Capitol Crossing at 222 Massachusetts Ave. NW, has an application pending before the FCC. The app calls for a repeater on 463.2500, and simplex on 463.7250, 464.1750, 466.5000, 468.7250, and 469.1750.

Washington Harbour Using DMR

Washington Harbour has been confirmed using DMR on 452.4375. Here are the two groups found:

452.4375 [         ] Security (DMR - Color Code 4, Slot 1, Group 1)
452.4375 [         ] (DMR - Color Code 4, Slot 2, Group 2)

No activity was monitored on the other frequency Washington Harbour is licensed for (464.3125).

Lt. Kevin McRae Funeral

The funeral and procession for DC firefighter Lt. Kevin McRae was on Friday. Three unencrypted talkgroups were active on the DC trunked system: DCFD Special Events 1 and 2, and the Emergency Management Agency talkgroup. Several other DCFD encrypted talkgroups were active that day; some of these were probably used in support of the funeral. Fire personnel from DC, Montgomery, Prince George's, and Charles were active on the Special Events talkgroups; the Montgomery units had 250xxxx radio IDs.

Marine Corps Historic Half Marathon

The Marine Corps Historic Half Marathon was yesterday morning in Fredericksburg. Here's what was monitored:

147.0150 [  88.5] Amateur Radio - K4TS
154.7250 [131.8] Fredericksburg Police 1 (patched to Spotsylvania talkgroup 02-041 and STARS talkgroup 98)
158.8350 [203.5] Fredericksburg Fire 3 (Medical Branch)
155.7150 [156.7] Fredericksburg Fire 7 (Celebrate Command)
Marines used temporary trunked system (388.5250 control, system ID 355, site 101, WACN BEE0A, NAC 350)

The Fredericksburg Police channel uses voice inversion, but the patched talkgroups allowed one to listen to all units. (The sound quality was poor on the STARS talkgroup.)

The trunked system that the Marines used is probably a mobile, low-power system. A similar system was used for the 2008 race. Due to the weakness of the signal, I was not able to determine if the talkgroups used were clear or encrypted.

851.8375 [141.3] was monitored shortly after the race; this frequency was probably used for car-to-car communications among visiting public safety units.

Hotel Monaco Alexandria License Modification

The Hotel Monaco Alexandria recently modified its license to add DMR simplex on 451.5125, 452.0375, 456.5125, and 457.0375. The hotel is already licensed for several VHF frequencies, so these frequencies may mean the hotel is switching to UHF.

Saturday, May 16, 2015

Renaissance Mayflower FCC App

The Renaissance Mayflower Hotel in DC has an application pending before the FCC. The app calls for one VHF frequency, and several UHF frequencies. The hotel's previous license expired in February. The new application makes some minor changes to the frequencies requested.

Monday, May 11, 2015

Arlington Trunked System Finds

A couple of new talkgroups found on the Arlington trunked system:
  • 21 School Security
  • 143 Wakefield High School
Having one of the high schools on the trunked system is a new development for Arlington (although it is done in some nearby jurisdictions, such as Alexandria). A couple of the other high schools are covered under a VHF license. Washington-Lee High uses 152.4050 [ d411]. Yorktown High is licensed for 152.3750, but has not been monitored. There doesn't appear to be a license for Arlington Mill High. The previously-mentioned license may cover that school as well as several others, as the license is for 300 mobiles.

Nationals Park - American Medical Response

American Medical Response, a company providing first aid services at Nationals Park, is using DMR on 452.2625. Here are the two channels found:

452.2625 [         ] (Ch. 1) (DMR - Color Code 3, Slot 1, Group 100)
452.2625 [         ] (Ch. 2) (DMR - Color Code 3, Slot 2, Group 101)

It's unknown if DC Fire is still using a frequency and/or talkgroup for ops at the stadium. Special Events 1/2 from the DC trunked system did not seem to be active for Friday evening's game.

Arsenal of Democracy Flyover Finds

Here's what I found at Friday's Arsenal of Democracy flyover:

118.9500 [ CSQ] Potomac Departure
134.3500 [ CSQ] DCA Tower - Helicopters (Airboss)
170.5125 [ $4C5] National Park Service - National Capital Parks Central

DC Trunked System talkgroup:

Arsenal of Democracy Flyover

The Arsenal of Democracy Flyover is on Friday, beginning at about 12:10 PM. The planes will leave from Culpeper and Manassas Airports, fly down the Potomac River, and then traverse the National Mall from the Lincoln Memorial to the Capitol.

National Park Service and Park Police frequencies should be active:

170.5125 [ $4C5] National Park Service - Medical/First Aid (R)
172.4750 [ $4C5] National Park Service - National Mall & Memorial Parks (R)
172.7500 [ $4C5] National Park Service - National Mall & Memorial Parks (S)
166.7250 [127.3] Park Police - Special Events (Channel 1)
166.9250 [127.3] Park Police - Dispatch (Channel 2)
167.0750 [127.3] Park Police - Administrative (Channel 3)
166.8500 [127.3] Park Police - Tactical Operations (Channel 4) (S)

Frequencies for Reagan National Airport and surrounding airspace should be active. The AirNav page for DCA has many communications frequencies.

DC 16xx Talkgroups

Today, more radio testing was done on 16xx talkgroups on the DC trunked system. Several of the talkgroups were identified by channel name:

1617 - 0-1
1619 - 0-3
1620 - 0-4
1633 - 1-7
1634 - 1-8
1635 - 1-9
1636 - 2-0
1637 - 2-1
1638 - 2-2
1642 - 2-6

These talkgroups may be used by Metro in the future. Metro is supposed to migrate from its UHF-T system to the DC system. Previous testing on some of these talkgroups was done in January, February, and March.

DSD+ 1.071 Released

DSD+ version 1.071 was released this morning. There is a RadioReference forum post about the release.

The major addition to 1.071 seems to be a built-in frequency tuner/scanner, which eliminates the need for a program like SDR#. It also eliminates the need for a virtual audio cable program, such as VB-Cable or Virtual Audio Cable, to route the audio from SDR# to DSD+.

Monday, May 4, 2015

National Zoo Update

The National Zoo is using the DC Area Fed SMR IDAS system. This system has replaced the PassPort system. The zoo was found to be using at least five frequencies. (Only two were noted in use when the PassPort system was active.) The increased number of frequencies is probably due to all personnel at the zoo using the system. Previously, only police, maintenance, and keepers were using the trunked system. Parking, guest services, concessions, and others were using UHF business frequencies.

Unfortunately, it appears all communications are encrypted.

Sunday, May 3, 2015

Virginia Gold Cup Talkgroups Found

Here are talkgroups from the Fauquier County trunked system in use for yesterday's Virginia Gold Cup:

24688 Sheriff Tac 4 (Parking)
26128 Event 2 (Medical)
26160 Event 3 (Medical)
30320 Wrecker Service

24688 appeared to only be used for exterior parking/law enforcement. Interior law enforcement may have been on a simplex channel. 30320 is a never-before-seen talkgroup, and was used to dispatch what sounded like a private wrecker service to disabled vehicles.

Friday, May 1, 2015

Weekend Events

  • Dulles Airport conducts an emergency exercise Saturday morning.
  • The Virginia Gold Cup is Saturday beginning at 12:30 PM at Great Meadow in The Plains, VA.

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.)

Friday, April 24, 2015

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.

Sandy Spring Friends School FCC App

The Sandy Spring Friends School, located in Montgomery County, has an application pending before the FCC. The app calls for fifteen UHF simplex frequencies.

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:
Production
15th Street
Tickets/Ushers
Talent
Assembly
Private
Dispersal
Volunteers
