Fellows I did find a AC-AC inverter. Don't know the price but have asked. ABSOPULSE
The FC 2KP-EW/A Series modular ac-ac frequency converter system was designed to deliver a clean sine-wave output from ″dirty″ generator voltage under extreme environmental conditions. 73s Will, KB7QL On Mon, Jun 15, 2020 at 4:00 PM Robert Polinski via BVARC <[email protected]> wrote: > Lots of generators have bad outputs.
