I don't mean to hijack this thread, but wrt Don's comments, yesterday I noticed that my K3 is behaving oddly after a tune cycle of the K3 internal ATU. On SSB, in the CQWW contest, it was taking at least a half-dozen transmissions of my call sign to get back to full power. I have the Power control set to 95 w., but after the the tune cycle output dropped to around 50 w., and VERY slowly returned to full output. This is normal except that it seemed to take a LOT longer than before. Does this indicate a problem (other than my frustration)?
