After last holiday with my beloved Elecraft K1 I realized I need some kind of zero beat tuning indicator on it. I find it very hard to tell if I tuned zero beat or not by only hearing. Googling around I found the K6XX cw tuning indicator. When I watched the indicator at work I ordered it immediately!
Although I ordered it a week ago, I didn’t hear anything yet. But I’m not in a hurry…
