Igor, The waveshapes are normal. They will not be anything like a sine wave coming out of a mixer, but the fundemental RF voltage is still present, so the waveform will be cleaned up by the bandpass filters and the PA Low Pass Filter. Since you have excessive current draw, the first place t

Hello friends, I built a kit K1 80/40. Everything was no problem. All values of resistors and DC voltages were OK. But in chapter 9, part "Band 1 Allignment", transistor Q7 has been melted (2W at 80 m band). I changed it and after that I measured current - 0.1 W on 3.6 MHz current is 1.1A! On 7
