SWR Protection Circuit - cuts power when SWR is too high
This design is from Ron WA7GIL. He posted it on the QRP Labs forum in early 2023.
V1.0 came back from the fab in May. Only 2 whitewire fixes. You can grab the Gerber and build your own if you don't mind fixing it when it gets back.
The whitewire changes were solved with a single change to the schematics, so V1.1 or better of the schematics would be the one to look at.
V2.0 now includes the "George Option", an optional alarm so you can hear when your radio has been shut off by the SWR Protector.
