Yes, I know exactly who you're talking about, although his name and call 
also escapes me at the moment. He recently joined the Gray Hair Net on 
1945, and yes, this guy is as strong here as the stations running full 
1/2 wave dipoles at comparable power. The vacuum variable has a voltage 
rating of 30KV; he said 15KV was marginal and arced over occasionally, 
due to the high voltage developed across it at modest (legal) power.
