Custom PCB design of an external S&Watt-Meter for radios. Useful for all enthusiasts and HAM operators.
This is still "work-in-progress (WIP)" so I do NOT take any kind of warranty/responsibility for damages or data losses!
You can use this at your own risk without guarantees!
If you like the new design yo are free to share it!
Have fun :)
