More Marathon Ideas

Here are a few more frequencies to try out during the Marine Corps Marathon tomorrow:
  • 123.0250 (AM) was active last year with helicopters. This is a common helo air-to-air frequency which is used nationwide.
  • 145.1900 [151.4] and 449.9750 [107.2] were active last year with amateur radio operators. It's unknown if the same frequencies will be active this year, but there's probably a good chance of it.
  • 154.6650 [ CSQ] was used last year by Virginia State Police doing traffic control on the 14th Street Bridge, I-395, exit ramps, etc.

Marine Corps Marathon

The Marine Corps Marathon is this Sunday morning. The marathon is one of Washington's biggest events of the year, and provides a wealth of scanning opportunities. Here's a preliminary list of what I'll be monitoring, in rough order of importance (I'll try to go into more detail in the coming days):
  • Marine Corps P25 Trunked System - look for talkgroups in the 63xxx range. In previous years, this system has seen widely varying levels of encryption.
  • Arlington County P25 Trunked System - numerous talkgroups will be active, especially on the police side.
  • DC Trunked System - look for the SOD channel and/or Citywide 2 to be active with traffic control. The three DCFD Special Events channels should see heavy use.
  • Metro Trunked System - expect Transit Police to be very busy with crowd control, especially at key stations like Arlington Cemetery, Rosslyn, and Pentagon. The Police Tac channels have been active in previous years.
  • Park Police - expect to see 166.7250 [127.3] (R) in use.
  • Crystal City Security - Crystal City hosts a big street festival during the marathon. Security active on 451.7750 [ d205] (R).
Notes from past years are on my Arlington County page.

STARS Coming Online in Northern Virginia

STARS, Virginia's statewide radio system, is slowly appearing in Northern Virginia. Yesterday, two new sites were online. Site 117, which appears to be transmitting from Fairfax, was using 152.2025 for a control channel. Site 119, which appears to be transmitting from Arlington, was using 152.5325 for a control channel. No voice traffic was heard on either in the late afternoon. Expect radio testing to continue for several weeks, at a minimum.

Washington International Horse Show

The Washington International Horse Show began yesterday and runs through Sunday. I had a chance to do some frequency-hunting yesterday; unfortunately, last night seemed somewhat slow, since it was the first day. Expect most of the best traffic on Friday and Saturday nights.

464.6250 [127.3] Inside Operations? (Channel 1) (R)
464.7250 [192.8] Outside Operations? (Channel 3?) (R)

Spotsylvania Regional Medical Center FCC App

The Spotsylvania Regional Medical Center, which is scheduled to open in June 2010, has an application pending before the FCC. The app calls for two UHF repeaters (452.4375 and 463.5625). The frequencies are coded with emission designators for both analog and MOTOTRBO.

Capitol Radio Communications FCC App

Capitol Radio Communications, which provides commercial radio services, has an application pending before the FCC. The app calls for two repeaters and eight simplex frequencies. The repeaters are supposed to operate at 22000 America Online Way. This is the headquarters of America Online, and America Online has used the two repeaters (463.4500 and 464.9750) for some time now. It's possible that Capitol Radio Communications is taking over the maintenance of the frequencies.

Update on Spotsylvania Rebanding

Spotsylvania has added another frequency to their rebanded trunked system. It's 852.6750 and it's in position 8 of the channel order (LCN). Note that for whatever reason, sometimes all the frequencies aren't used. For example, yesterday 851.6125 was not being used. It's a good idea, however, to keep all the frequencies programmed, as one never knows when they will turn a frequency on or off.
