Using 2 tone test with Expert 2K-FA I see -65db or better. I see typically -60 on SSB.
Using 2 tone test with Elecraft KPA1500 (2XLDMOS) I see -50db. I see typically -45 to -50 on SSB.
Both at ~1200W out.
Disappointing as for other reasons I'm switching to the KPA1500, but from what I understand its the nature of the beast with LDMOS devices. Nothing the amp maker can do about it.
