Marine Corps Historic Half Marathon Sunday

Fredericksburg will be hosting a big event Sunday morning beginning at 7 AM - the Marine Corps Historic Half.

Fredericksburg Police use voice inversion on their Dispatch and Tac channels. Interestingly, Channel 3 (156.1050 [69.3]) does not have inversion.

Fredericksburg Fire uses nine channels:

154.4150 [71.9] Dispatch (Channel 1) (R)
154.4150 [71.9] (Channel 2) (S)
158.8350 [203.5] (Channel 3) (R)
158.8350 [203.5] (Channel 4) (S)
159.0600 [203.5] (Channel 5) (R)
159.0600 [203.5] (Channel 6) (S)
155.7150 [156.7] Mary Washington Hospital (Channel 7) (R)
155.7150 [156.7] (Channel 8) (S)
153.8150 [156.7] Tac 5 (Channel 9) (S)

Channel 3 is used as a fireground channel, and Channel 9 is used for training, but Channels 5/6 or Channels 7/8 may be in use for the race.

Organizers may use the Fredericksburg site (405) of a multisite Marine Corps/Navy trunked system. The first year of the race, organizers used a couple of UHF business frequencies.

Amateur radio operators have been active on 146.4900 [CSQ] in previous years.

See the Fredericksburg page of my website for all the details of what was used in previous years.
