Hi Bill,
The answer isn't fundamentally different whether you say CW, RTTY or SSB
(PSK-31 being a notable exception). FCC rules suggest minimum power required
to get the job done.
High-power RTTY will stress your system more than CW or SSB, due to the 100%
duty cycle when transmitting. This means the transceiver, amplifier, tuner,
antenna, coax, etc. (don't forget about RFI and neighbors too!) I burned out
an R7 trap on 15m calling E44/HA1AG (never did work them).
I generally run 100W in contests, and prefer to run the amplifier (AL-1200)
ONLY when it's a "new one" that I probably would not have worked without the
additional power. Even then, I tend to keep the power below 1000W to be on the
safe side.
I remember working VR2BG on 10m RTTY in the WPX contest running just 100W, but
on the other hand called another DX station (who I can't recall) with the KW
for 20 minutes until they heard me (and there was no one else calling!). Let
propagation be your guide.
