This YouTube video was sent to me by John WB6YZF, In 1984 the Silverado Amateur Radio Society was busy supporting the CDF (Now CalFire) in their Volunteers in Prevention program. We spent many hours monitoring ground activity in the wooded areas of Napa County, from private aircraft.
Most of the HAMS seen in the Video are no longer with us but many are. The video opens with a meeting in St. Helena at the Department of Forestry headquarters on Railroad Avenue.
