I just finished my KX1 and ATU, Yeah! In tuning the ATU for a null I get about .4 mV (there are two nulls), at both nulls the power reads 2.2 watts.
If I look at the RF out on my scope I see a peak to peak reading of 18.8 volts into a 50 ohm dummy load. I compute power to be 3.24 watts. (Vpp/sqr 2)^2/50ohms, P=Vrms^2/50. I'm feeding the KX1 with 13.8 volts. Does anyone have any suggestions where I might poke around with my scope to see why I'm not getting 4 watts?
