Hi iw2fvo,

Since I do commercial designs they are generally a client's property which I cannot publicly distribute. So to produce a Sinewave Inverter the hardware itself could be a great obstacle. PCB being one important component. So I am planning a make a fresh simple hardware design that can be easily produced by an average hobbyist.

BTW to run the radios you would need 13.5 Volts DC (my ham license never got renewed) if I am not wrongs so what are the loads you plan to use with your inverter.
