I finished the KNB1 noise blanker today and installed it in the K1. When finished, I connected the K1 to my ATX-1080 set to the 40 meter band. I put the OHR WM-2 wattmeter and the T1 antenna tuner in between the K1 and the antenna. First I tried to put the T1 into bypass mode, but I wasn’t quite sure whether the yellow LED meant bypass on or tuner on… Later I found out that green led means tuner on, yellow led means bypass on.
