Charly, sadly there's an over-hyped obsession out there about Tx purity and
associated IMD specs for ham rigs....

Having said that many current SS amp offerings are poor performers in this
regard when driven to their rated PEP output :-(

I do not know anything except that when I ran my Yaesu FT-1000MP Mark 5 at
40 watts to drive my tube amplifier in Class A, I burned up that radio so
well that two other very smart men could not fix it, including Yaesu London.

That orange button is not something to be touched.    73, Charly

P.S., the defenders will arrive on schedule, but I say, why risk it?   The
Elecraft Lovers Club started this hurrange about transmitter purity.  In
fact I read the very first message of what has spread like psoriasis where a
ham demanded in one post that anyone not running a K3 should have their
contest scores reduced.  No kidding.
