I haven't been following this thread in detail, so so this may be a shot in the dark. But I remmeber in my eagerness to try my K2 as I was building it, I connected the antenna before I had done CAL FIL for the very first time. It received fine, but the VCO was moving in large steps, I believe 5 kHz or so. -- 73, Sverre ------------------ Sverre Holm, LA3ZA www.qsl.net/la3za
