Bryan, captbrian wrote: Actually, rotary gaps were not at all uncommon, even in amateur use. They were divided into two types, synchronous and non-synchronous, depending on whether the gap timing was maintained on the AC voltage peak . The non-sync was simpler to produce, and most of the amateur rotary gaps were of that variety. But with a sync gap setup, you could achieve the cleanest note, as you described in your message.I believe only large and expensive installations on posh ocean liners. hadrotary spark gaps. < John Andrews, W1TAG |
