More info would help.? Can you make any adjustments?? Are you sure you have the audio input as specified in the TX setup -- correct connections and right signal level?? Have you verified your coax and dummy load present a 50 ohm load and the DC voltage at the radio are above 13 VDC?
Does the radio produce TX power when operating in normal mode on 10 or 14 MHz?? ?
I've never had any problems doing the adjustments per the procedures, if the radio is working correctly.
