Actually as easy to design an RF Clipper as an audio compressor. True
it is a bit more difficult to install. Audio clippers can be external
to the transmitter and simpler to install and operate. A RF Clipper
will install as easily as your internal audio compressor.

Personally I would take RF clipping over Audio compression any day
with SSB transmissions. If the post filters are good in enough RF
clipping, there is not significant difference in distortion.
