Better to find and solve that problem than building a SWR meter i find. I'm not using any protection circuits for my PAs, just an Amperemeter is showing the antenna current. That is important, having no Amperemeter would be like driving a car without a tachometer :-) 73, Stefan Am 14.11.2016 15:31, schrieb Chris Wilson: > Hello Stefan, > > Monday, November 14, 2016 > > Thanks, that's very kind of you.
