SoCal SOTAFest

Saturday August 1, 2020 to Sunday August 2, 2020



On Saturday, August 1, 2020 through Sunday, August 2, 2020, amateur radio operators from around Southern California will be hiking up to the tops of California's greatest summits to make radio contacts with other operators locally and around the world. If you are new to ham radio, this is a perfect opportunity to get outdoors and practice your radio skills with a supportive and amazing group of people. SOTA (Summits on the Air) is an award scheme for radio amateurs that encourages portable operation in mountainous areas. You can find more information on the SOTA website here. The SoCal SOTAFest event has three main goals (besides having lots of fun):

  1. Make summit-to-summit contacts with other radio operators and wrack up activator points for the group. Activators are those who summit a mountain to make radio contacts and earn SOTA points.
  2. Provide an opportunity for people new to SOTA to experience the thrill and adventure of hiking up to beautiful and remote destinations and making radio contact with others.
  3. Give "chasers" an opportunity to earn tons of chaser points. Chasers are those who seek to earn points by making contact with mountain activators.

If you are new to SOTA and would like to join someone on a hike to a summit to activate it, please join our group and post no our mailing list using hashtag #sotafest. Due to COVID-19, we ask that you consider safe practices like washing hands with soap or sanitizer if sharing gear or supplies.

General Event Information

The SoCal SOTAFest will take place the first weekend of August from Saturday August 1 to Sunday August 2. The event will run from 6am on Saturday to 9pm on Sunday. You do not need to be in Southern California to participate in the event, but making contacts will be much easier if you are.
