Weekend Events

Busy Labor Day weekend:
  • The Nationals play Friday at 7:05, Saturday at 4:05, and Sunday at 1:35 at Nationals Park.
  • Maryland plays William & Mary Saturday at 3:00 at Byrd Stadium. The university's trunked system should be very active; it's unknown if this system has been rebanded. Several conventional frequencies are also used; see the Prince George's page for these.
  • The Nation's Football Classic is Saturday at 3:30 at RFK Stadium. See the Washington, DC page for RFK frequencies (scroll to Business / RFK Stadium).
And a big event in Baltimore:
  • The Baltimore Grand Prix is Friday, Saturday, and Sunday at the Inner Harbor. Several public safety trunked systems will be in use: Baltimore, CMARC, and FIRST. (Note that some talkgroups on FIRST use Phase II TDMA modulation, which cannot be monitored with any scanner.) Race organizers will probably use UHF repeaters/simplex, possibly MOTOTRBO. Racing Electronics held a license for last year's race; it's unknown if these frequencies will be in use again this year.

Another Stafford Schools Update

Stafford Schools continue to conduct radio testing on several UHF-T frequencies. The schools are apparently going to use the UHF-T frequencies that Fire used previously. 488.6375 [156.7], which was Fire Channel 2, was referred to as Channel 1. 489.1125 [156.7], which was Fire Channel 3, was referred to as Channel 2. No MOTOTRBO was monitored, so they may use the frequencies in analog mode, at least for now.

AirCare 2 and King George

AirCare 2, a medical helicopter based at Shannon Airport in Fredericksburg, was responding to a motor vehicle accident this afternoon in King George. The helo tried contacting the county on 155.7600 [ d412], but received no response. The county currently uses 155.7600 [141.3]. (The tones were switched from DCS to CTCSS several years ago.) I believe the helo was able to land at the scene without any problem, but this incident highlights the importance of keeping responders informed of radio system changes.

Arundel Mills Mall Major Update

Updated frequencies for Arundel Mills Mall are on the Anne Arundel County page. (Scroll down to the "Business" section.)

  • Capital Gallery, located on Maryland Ave. SW between 6th and 7th Sts., is using a MOTOTRBO (Color Code 1, Slot 1, Group 1) repeater on 463.7250. The license incorrectly indicates that the frequency is only used in analog mode. Note that this frequency (with the same color code) is also used by The Rotonda in Fairfax County.

380 MHz Control Channel Found

There is a 380 MHz Project 25 control channel (387.7875) that appears to originate from the Fort Belvoir North Area, in the Newington section of Fairfax County. Because I was driving, I was unable to analyze the control channel, but I suspect it's part of the Joint National Capital Region system.
