Hmmm 🤔, Irregularity found on the #ATU100 #N7DCC not a matched pair of 1N5711 as in schematic. Different diodes on fwd and rev paths of SWR bridge could lead to incorrect/false matching. @TheSmokinApe had same issue. I recall work done by Rafael #PU1OWL https://t.co/6tyr54FHLh

So I built one of those cheap $30 #N7DCC tuners (see pic). Put it in case. Found performance TERRIBLE. Always ran it off a 9v as it supports it and wanted to use portable. Added a barrel connector for 13.8V power supplies. Surprise: with sufficient power +grounding tunes well!
