Don: While I had to use my 50 MHz scope to take the RF readings, the big signal drop you told me to look for seems to be at the Pre-Driver output. Instead of .120 Vrms, I am looking at about 0.20 Vrms or less. Not much difference when Tune is pressed (key down). The T-R switch output is also very low but is (apparently) supposed to be. I have checked all resistor values for the Pre-Driver amplifier circuit and they are all correct markings. Tomorrow I will concentrate on those solder joints as well T1 and T2. Sound right Thanks
