Course & Rest Stop Changes

Short Rides Added
New for this year is the addition of two shorter rides. Both short rides will start and end in Davis. They will leave Davis and travel reverse course to either Rest Stop 1/Forbes Ranch (short ride) or Rest Stop 7/Guinda (medium ride), and then return to Davis.

As of 8 May 408 doubles, 18 century, and 8 45 milers are signed up.

Pre Ride Meeting

Thursday May 18 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), 900 radios, and 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.

Friday Set Up

Net Control set up at the Veteran's Memorial in Davis will be on Friday May 19 at 1730 hrs. All help appreciated. Leftover SAG materials (first aid, sag boxes, pumps) and t-shirt bags w/maps and other docs will be available for pickup

Radio Plan

The radio plan will be similar to last year's, with 2m and 900 MHz being used. In addition, when the airborne repeater/digipeater is flying, a 440 MHz repeater linked to the 900 MHz repeater will be available. The 440/900 MHz airborne repeaters will provide handheld level coverage.

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.


A separate packet frequency with special event digipeaters located on the course and in the airplane will be used. We do not use the national 144.390 frequency due to coverage and congestion issues. Net Control will be equipped to track APRS equipped units. Yaesu location beacons are not displayed on our ancient APRS+SA program but net control will try to keep track on aprs.fi for any Yaesu beacons (VX8, FT350, etc.)
