Bay Area Skydiving at Byron, CA
PACIFICON 2011, an annual amateur radio convention, will take place Friday, October 14th through Sunday, October 16th, at the Marriott Santa Clara Hotel, 2700 Mission College Boulevard, Santa Clara, California.
One of the activities is Parachute Mobile where radio-equipped skydivers perform radio contacts, transmit bio-medical data and live television while in the air under parachute. Jumps are scheduled at Byron Airport in Contra Costa county on other side of mountain range from Livermore. Air to ground amateur television (ATV) will be done at the airport. Received video will be internet streamed via justin.tv to be viewed by Pacificon attendees at Santa Clara Marriott and watch live television transmissions from the skydiver.. It was first planned to re-transmit these video transmissions to W6CX ATV repeater on Mt. Diablo. An ATV receiver at Ames Amateur Radio Club would then re-transmit this signal to K6BEN ATV repeater on east San Jose foothills.
A number of technical hurdles are present but AARC members are working in cooperation with those on Parachute Mobile, W6CX, and K6BEN teams. Presented here are some of the items used in this activity.
Depending on event schedule, AARC may re-transmit amateur radio activities on ISS during weekend of Pacificon.
