How strange to say that about RTTY contests, because RTTY is a 
constant-level mode where any "sidebands and splatter" are guaranteed 
*not* to have been generated in the amplifier!

The transceiver, the amplifier, the antenna and the propagation can all 
increase the levels of "sidebands and splatter" that other people 
hear... but somehow, only one of those gets the blame.

The large majority of amplifiers that require only 30-50W drive create 
no higher levels of far-out IMD than the barefoot transceiver at 100W 
(and I do mean absolute levels). Many stations are actually *less* 
noticeable elsewhere on the band when using an amplifier.

Of course the main signal is louder when using an amplifier; but (and 
how often do we need to say this?) being loud is not a crime.
