Soft compressors and clippers have been used for years and are effective
for FM and AM modes, but can have limited effectiveness for SSB. The
problem is that if the processing is made aggressive enough to be
effective, the distortion products increase rapidly. It ends up a Catch-22
situation. The wattmeter goes up but articulation goes down.

The r-f clipping and filtering approach which prevents the distortion
products from appearing in the output passband is still regarded by most
folks as the most effective process to both increase average power and
increase articulation.
