That's ok... My 1KV load capacitor will arc (acting just like a spark
gap....) across before the 3 KV padders will.
BTW I never have had my 1KV loading cap arc. EVER! And I contest on RTTY with it. 73 Jim W7RY On 12/4/2013 12:01 PM, Bill Turner wrote: ORIGINAL MESSAGE: (may be snipped)On Wednesday, December 4, 2013 10:51 AM, peter chadwick <g8on@fsmail.net> wrote: If one is to believe Philip H.

REPLY: I find that hard to believe but I can't actually disprove it. However I guarantee that if you transmit high power into an unterminated coax, the Tesla Coil effect in your output tank will cause some extremely high voltages to appear across the load cap (and everywhere else in the tank). And that is what the discussion is about. 73, Bill W6WRT _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
