Re: Tuning Primary

Hi,
We also need to tune like say +-10nF which is far greater than any varactor and most high voltage tuning caps... 

Cheers,

Hi, the amount of voltage and rf current in a primary and the chance of a
static strike precludes the use of anything but very tuff semiconductors.
varactor diodes are neat signal items but far too weak for tuning a primary.
