Marine Corps Marathon

The Marine Corps Marathon, which takes place this Sunday in Arlington and DC, is one of the Washington area's largest events of the year. Here are ideas for things to monitor:
  • Marine Corps Trunked System This trunked system is used by the race organizers. Site 403 has seen use for the past several years. Talkgroups are in the 63xxx range. For the 2006 and 2007 race, almost all of the transmissions have been encrypted.
  • Marine Corps Trunked System (Temporary/Mobile?) This trunked system was first noted in use at the Marine Corps Historic Half Marathon in Fredericksburg earlier this year. All transmissions were encrypted. It's unknown if this system will be used for the Marathon.
  • Arlington County Project 25 Trunked System Police will probably use numerous talkgroups. Fire will probably use special events talkgroups (43, 44).
  • Arlington County Motorola Trunked System The Virginia Hospital Center talkgroup will likely be active with patient reports. Several Police/Fire talkgroups are simulcast from the Project 25 system, but they will likely not see use for the race.
  • Washington, DC Trunked System Metropolitan Police may use talkgroups 16656, 18288, and/or 21232 for traffic control. DC Fire will probably use their special event talkgroups (2096, 2112, 2128).
  • Park Police (probably Channel 1--166.7250 [127.3])
  • Capitol Police (probably Channel 3--170.1750 [156.7])
  • Washington Metropolitan Area Transit Authority Trunked System Metro Transit Police may use their Tac channels for crowd control at some of the busier Metro stations.
  • Crystal City Security (451.7750 [ d205])
