I'm interested in home-brewing an AM transmitter for 160 and 75 meters. I would like carrier power in the neighborhood of 200W, but I have a spare linear amplifier so I could make do with 20W. I've heard of Class E, and I'm trying to get my head around it.
First, is low level modulation out of the question? Can modulation be accomplished by driving the amplifier with a PWM signal at the RF frequency?
Is there an existing Class E design available with boards for sale? (or maybe a complete kit?)
BTW, do AMers always specify output power by "Carrier" rather than "PEP"?
