Below is a link to an interesting page on the Dressler site. The page has three useful resonance calculators, which allow you to work out various combinations of L, C, and F, etc. You can save the page locally on your PC, and it will still work! While you're browsing the site, take a look at the big LF power amplifiers they make! http://www.dressler.com/more_about_rf/rf_formuler_resonant.html Cheers, Dave G3WCB.
