I studied that question quite a bit a couple of years ago before I bought a
Quadra, and decided the Yaesu's 500 watt rating was for continuous
"broadcast" RTTY, whereas the ICOM's KW rating was for the usual ham 50/50
duty cycle. As I recall, the transistors are the same, and the Yaesu's PS
actually has a slightly higher power capacity rating. I concluded
Yaesu=ICOM as far as PO on RTTY is concerned.
An aside: I also wondered why the amp's 6M rating was only 500 watts. Turns
out that 500 W is the max legal power in JA-land, where these things were
designed and built ! I think I remember seeing that the transistors have no
such artificial power limit on 6. I don't operate 6, but would crank it up
to full KW in the USA if I did. I would check for spurs first time, of
course, but wouldn't expect to find any.

But these are the RTTY and N1MM reflectors...
And the Yaesu products are only rated half-power on RTTY...
