Once the "driver", i.e. transceiver is operated linearly for soundcard
RTTY, a non-linear class-C amp can follow and the result, and high
power, is the same as direct FSK, because the drive to the amp is a pure
RF signal - no competitive loss to the high power contester!

Agreed, though the IMD might be a problem, especially as many RTTY
contesters use class C amps. Of course, you could also argue that they
wouldn't need to use as much power...
