Course & Rest Stop Updates

Start/Finish

Course and Rest Stops

The ride will follow the same course, with the same rest stop locations, used in 2025.

Pre Ride Meeting

Thursday May 14 at 1900 hrs.
The pre-ride meeting will be held at the Parking Lot behind Davis City Hall, at the corner of Russell Blvd. and B Streets. Directions to City Hall can be found HERE. We will be meeting at the west end of the parking lot, closest to A Street.

Talk-in on the K6MVR repeater, 147.000 - 136.5. SAG boxes, info packets (shirts, maps, freq plan), and a limited number of APRS trackers should be available. Any op not able to make it can make other arrangements or pick up their stuff at Net Control on event day.

Net Control Set Up

TBD - Net Control Will be set up Friday after 1700 hrs. Antennas will be set up outside Saturday morning.

Radio Plan

The radio plan will be similar to last year.

Net Control will be geared towards having enough ops to handle simultaneously 2-4 channels, minimizing the time needed for field units to get a response.

APRS

APRS will not be used as part of the radio plan but if SAGs are equipped with a tracker and on the national frequency they will be monitored using CalTopo. If you don't have a tracker, a cellphone app can also be used

Roster

This is the roster and shifts as the positions are being filled.
