Putting aside the rule for a moment, I run across a lot of folks who run
radios on RTTY at 30 to 50 watts when their radios *can* run 100w
continuously.
Over the last 20 years or so I have run 100w from all of my radios in RTTY
contests. These radios include the TS-850, TS-2000, IC-756Pro3, and
FT-1000MP. One of my RTTY contesting buddies here in town has done the same
thing with these same radios as well as an Omni 6+. Over many RTTY contests
with many thousands of QSOs neither of us have ever had a PA failure.
I am sure there are a number of radios that clearly will not support 100%
duty cycle operation at full power, and it's prudent to run them at reduced
power. But a great many modern (and not so modern) transceivers run fine at
100w RTTY, and in my opinion it makes a heck of a lot more sense to run
them at 100w than to throttle them back and run an amplifier, especially a
tube amp.
