G'morning John: The number displayed when one adjusts the PWR knob is a COMMANDED power level. If the K3 has been calibrated using the procedures in the manual, then the power out will be what is commanded, assuming a 50 ohm resistive load.
My K3 commands powers between 8.5 and about 13 with no problem. Six meters used to not be able to do that, but a recent firmware upgrade solved that problem on 6 meters. 73, Ken K3IU K3 #202 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ On 9/13/2010 8:51 AM, John Ragle wrote: > Referring to my K3/100 Ser.
