Thanks for the flowers!
Many, many hours testing on this design.
Didn't want any complaints from the SDR Googlers!
I've found it will easily cover 1MHz, so 6.0-7.0 MHz with 40W o/p and >90% efficiency.
The 40W is also VERY conservative but wanted to keep it reliable and the cooling requirements minimal. A small integral fan is included.
Class D modulator, 160 size MT, Class D/E GaN generator with AD9833 programmable DDS.
No junk box components, All the latest tech.
