Dear all, I'm not a designer, but I do like to build. If the balanced auto ATU gets off the ground I'd love to have a go at one as I use a balanced antenna here. I do have a Z11 and choke balun, but currently prefer a ZM2. An auto ATU for balanced line would be a great project. 72/73 Paul M0CDP GQRP 10289 Fists 5579 K2 #2356
