Hi Gary, Alan, yes, as Alan says, class E amplifiers are very forgiving. In addition to Tonne's program and Alan's Excel spreadsheet you may want to have a look at Nathan Sokal's QEX article to learn how to tune the amplifier for maximum efficiency using an oscilloscope looking at the FET drain waveform. Adjust the FET parallel C and the series LC tank to get a "soft landing" before FET turn-on again. http://www.classeradio.com/sokal2corrected.pdf By the way, Nathan Sokal, WA1HQC, "invented" class E!
