[Elecraft] K3 tuning power question

[Don Wilhelm]

Dick,

It is easier on the K3 to tune at 15 or 20 watts.
Reason -- at 10 watts, only the low power PA is active and it will be 
operating near the upper end of its range.
Increasing the power activates the 100 watt amp and at 15 or 20 watts, 
everything is loafing along at much less than its full output.
