Apparently you did not bother to read TXNoise.pdf   In it, I observed 
that ARRL tests of the TS590S showed it to be second best to the K3, 
twice as clean as the ICOM rigs (7600, 7800), four times cleaner than 
Yaesu FTDX5000.

BTW -- N7WS, a highly respected US engineer, told me in direct email 
that the 590S does have a problem with spewing low level noise when it 
goes into TX. He discovered and documented this several years ago, but 
I, and probably most others, missed it.
