Sporting events on this hot weekend:

EDACS Narrow System Near Reston?

While at Reston Town Center this evening, I monitored what I believe is an EDACS Narrow control channel on 452.6125. I could not find any plausible licenses for this in Virginia or Maryland.

Weekend Event

This weekend, the focus will be on the Civil War reenactment events around Manassas. Expect the Manassas/Manassas Park and Prince William trunked systems to be busy. Manassas National Battlefield Park uses a digital repeater on 172.7250 [NAC 47C]. Look for organizers to probably use rented UHF business band radios. Parking for some of the events will be at Jiffy Lube Live, which uses these frequencies:

151.6550 [ d071] Jiffy Lube Live - General Operations (R)
151.7150 [ 67.0] Jiffy Lube Live - Security (Channel 2)
151.7450 [ 67.0] Jiffy Lube Live - First Aid
151.7750 [ 67.0] Jiffy Lube Live - Production?

Jiffy Lube Live is licensed for one additional frequency, 157.6800 (although this may be the repeater input to 151.6550).

Rosslyn Update

I did some monitoring in Rosslyn on Thursday, and picked up a few unidentified frequencies.
  • 451.8625 [ d165] "card reading" (R)
  • 461.1125 [ d523] "walk down to statue"; "scaffolding"
  • 463.5125 [ d754] "hotel lobby"
  • 464.9875 [ d654] "trash"; "west" (R) (also monitored in Pentagon City)

MOTOTRBO Capacity Plus Systems in DC Area

There are a few MOTOTRBO Capacity Plus systems coming online in the DC area. One is on 461.5500. The signal is medium-strength from Rosslyn, but seems stronger farther south, like in the Landmark area of Alexandria. 462.1000 is probably part of a different system, as its signal is stronger in Rosslyn. 463.5500 is also strong in Rosslyn; it may be part of the same system as 462.1000. These latter two frequencies were recently licensed to Catholic University (but as analog channels). But that didn't stop Catholic from using 464.5750 as a MOTOTRBO conventional channel, so maybe these two are for Catholic as well.

Rappahannock Regional Jail Using MOTOTRBO Capacity Plus

The Rappahannock Regional Jail, located in Stafford County, is now using a MOTOTRBO Capacity Plus system. This is a single site trunked system. Previously, they were using their MOTOTRBO channels in conventional mode. The system has at least three frequencies: 453.8125, 453.9000, and 460.3875.

New Encrypted Talkgroup on DC Trunked System

24640 was noted yesterday as a new encrypted talkgroup on the DC trunked system.

156.1500 [ CSQ] Spirit of Mount Vernon
156.6250 [ CSQ] American River Taxi?

  • 50160 was in use on July 4, and is Metro Transit Police Tac 5.
  • 50992 appears to be Metro Headquarters security.

National Independence Day Parade

Organizers of the National Independence Day Parade were using 464.2750 [ d445] (S).


On Monday, MOTOTRBO transmissions were monitored in downtown DC on 464.8750 and 452.3500. I'm unable to find a MOTOTRBO license for 464.8750. 452.3500 is probably the Marriott Wardman Park (see this license).

National FreedomFest Frequencies Found

I found two frequencies in use for the National FreedomFest, which took place on Sunday and Monday:

461.5125 [ d152] CSC Event Staff (S)
464.5000 [ d132] Organizers (S)

Smithsonian Folklife Festival

The Folklife Festival is using the DC Area Fed SMR this year. This is an LTR Passport system that cannot be tracked with current scanners. In recent years, the Folklife Festival has used rented UHF radios.

Arena Stage

Arena Stage has been confirmed on 464.4375 [ d032] (S). This frequency is also used as a repeater by the Fashion Centre at Pentagon City and by the Marvin Center at George Washington University.

Arlington County EM Talkgroup

On Monday, Arlington County was using talkgroup 117 (Emergency Management 1) to deal with downed trees from the recent storm.

Friday, July 1, 2011

Weekend Events

A slew of events for the July 4 weekend:
  • The Nationals play Friday at 7:05, Saturday at 3:35 (with second game to follow), Sunday at 1:35, and Monday at 1:05 at Nationals Park.
  • The Folklife Festival runs all weekend. See previous post for information.
  • DC United plays Saturday at 7:00 at RFK Stadium.
  • The National FreedomFest, a musical event, is Sunday and Monday at The Yards Park (near Nationals Park).
  • On Monday, there are numerous events in DC, including the National Independence Day Parade on Constitution Avenue, A Capitol Fourth concert on the West Lawn of the Capitol, and the fireworks. The usual MPD/DCFD special events talkgroups will see heavy use. Also monitor Park Police and Capitol Police. Finally, many Arlington County talkgroups have been busy in recent years.

Smithsonian Folklife Festival

The annual Smithsonian Folklife Festival began yesterday, continues through July 4, and then returns from July 7-11. In recent years, organizers have used a variety of UHF frequencies. They will most likely use frequencies in the 461-470 and 451-453 MHz range again this year. There is also a possibility they may use MOTOTRBO, as TRBO radios were seen one year (but they were using analog frequencies). Look for Park Police on 166.7250/166.8500.

Presidential Building FCC App

The Presidential Building, an office building located at 1111 Pennsylvania Ave. NW, has an application pending before the FCC. The app calls for MOTOTRBO simplex on 461.5125 and 464.3125.
