Maryland State Fair

The Maryland State Fair runs today through September 7 (Labor Day). I don't have notes from a previous year, but I do remember the radio usage by the fair organizers was fairly minimal for an event this big. I think they were using a VHF business channel in simplex mode. The Baltimore County Public Safety trunked system and the Baltimore County Services trunked system will probably have some active talkgroups.

Sen. Kennedy Events Tomorrow

Sen. Kennedy's body is scheduled to arrive tomorrow at 3 PM at Andrews AFB. The base P25 trunked system should be active. At 4:30, the motorcade will arrive at the Capitol. Here are the Capitol Police frequencies:

165.5375 [146.2] (Channel 2)
170.1750 [156.7] (Channel 3)

173.5250 [167.9] Specialized Teams

The burial is at 5:30 at Arlington National Cemetery. The Cemetery uses 165.1875 [156.7] (R). Also, the Joint National Capital Region - Fort Myer trunked system could very well see use by ceremonial units.

Chevy Chase Bank Building FCC App

The Chevy Chase Bank Building at 7501 Wisconsin Ave. in Bethesda has an application pending before the FCC. The app calls for a repeater on 451.8250.

Arlington County New Encrypted Talkgroup

Arlington County is using a new encrypted talkgroup on their P25 trunked system. It's talkgroup 193, which is one above talkgroup 192, "Arlington Public Health 2."

Montgomery Trunked System Works in Metro

Not sure if this has been mentioned before, but the Montgomery County trunked system works underground in the Metro (at least at the Bethesda station). This means that DC, Arlington County, and Montgomery all have underground Metro coverage.

Arlington and Montgomery County Fairs

The Arlington County Fair (closes today) is using talkgroup 11 for Police and talkgroup 105 for Parks & Recreation organizers from the Arlington P25 trunked system. Talkgroup 105 has never been seen in use before.

Women of Faith Frequencies Found

Here are frequencies found from the Women of Faith conference this past weekend. These frequencies won't be useful in Washington until next year, but the conference will be traveling around the country for the next few months, and I expect these same frequencies to be used.

Legg Mason Tennis Classic Frequencies Found

Here are some frequencies in use at the Legg Mason Tennis Classic, which continues through this Sunday. They apparently are not renting the radios from Valleywide Communications this year, as the frequencies are different from what they've used in the past.
