Pre Ride Meeting

Thursday May 16 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

Outside antenna setup only, no setup inside from 1700-1800.

Radio Plan

The radio plan will be updated to accommodate coverage needs for the revised 100 mile route.

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.


For DC 2019 the aprs frequency will be 144.390 with path wide1-1,wide2-1 recommended. 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.)
