Hi Bruce, I expect you are correct ... a different method of setting the output. The strategy described by chip is the method I use with my old Kenwood TS-50. But since the TS-50 has no ALC indication I used the monitoring method to determine the amount of drive that initiates a drop in IMD. The TS-50 is rated at 100W PEP output on SSB ... however careful monitoring indicates the IMD drops dramatically beyond 15W output! I operate between 10 and 15 watts and get great reports. I will have to get used to KX3 method of controlling power output.
