Yes, and I've done exactly that. My rigs are all K3s. I sold a pair of 
FT1000MPs to buy the first one. :)

Oh, but they ARE in violation.  FCC Rules clearly state that hams SHALL 
use the minimum bandwidth needed for the transmitted mode. ARRL Labs 
tests most new rigs when they are introduced. You can find a comparison 
of their measurements about 20 of those rigs here. 
http://k9yc.com/TXNoise.pdf  Their tests clearly show that the K3 is the 
cleanest of all mass-produced rigs, and that the Kenwood TS590S is a 
close second. The 590S is not an expensive rig, selling for about $1500 
last I looked. Those other rigs -- Yaesu and ICOM, use 2-4x the 
bandwidth of the K3, and they do that because they are VERY careless 
about their design of CW keying!

>   So it comes down to opinions.  Opinions with the only ability to change the status quo is to talk with their pocketbooks.  I don't believe the opinions expressed in these forums will do little to sway Yaesu, which seems to be the worst offender according to commentary.

I don't place much credence in opinions, and I almost never express 
opinions. When I say something about a technical issue, I am stating 
facts as I have taken the time to learn them.

>   I plan to operate my dirty beasts (Yaesu and Flex) in a multi-station setup later this coming year, we will see what a menace they really are....The Yaesu FTDX 1200 was operated last year with no issues.  We will run some tests this year in an effort to identify impacts.

No need to "run some tests" unless you're going to improve on what ARRL 
Labs is doing with very expensive and state of the art test gear.
