The 500 Khz rig that I built in a  couple of hours. Components from the junk box. The FET driver in this case was a complimentary pair of transistors.

Class E single ended one FET.

At the start I used a xtal osc then changed to the IC706 as an exciter, a couple of diodes to SQ the sinewave.

The tank cct inductor is an old WW2 ceramic ex TU7B tuning unit.

I put a good signal into the USA es Canada es Moscow with this transmitter on CW.
