Another RF Amplifier

This time the output power is mere 16W which ought to cover a small city under the right conditions. The input power needed is improved, now only 0.25W which can be directly provided by most oscillator/modulator stages (depends on the design). The efficiency I haven't measured thoroughly but it should be around 50%

Why do the L and C values vary along your transmission line? I'm not too familiar with the nuisances of RF ccts. What does that represent?

That's not a transmission line. It's an output filter, to clean up the harmonics of usually very dirty class C amplifier. You're bound by law to always put an output filter on whatever transmitter you make.
