Benny, I recently had Elecraft replace a KLPA3A again. They also did the Tx IMD mod and an alignment. I am now seeing the following 3rd order IMDs:
4W -40 dBc 8W -40 dBc 9W -35 dBc 10W -30 dBc 12W -20 dBc What is also encouraging is that now the higher order IMDs (5, 7 & 9th) stay at least 10 dB below the 3rd. Some of these were equal or higher than the 3rd last summer when I was discussing the problem with Elecraft. Obviously they have made some notable improvements since then. The two tone envelope still looks more like a square wave at 12W, but this radio is spec'd as a 10W transmitter that is clean to -30 dBc, so it appears they are now meeting their advertised spec.
