This scheme is also taken even further into the cutoff region in CB-land
and used to obtain a low level carrier, say 1 watt, while still obtaining
12 watts peak envelope levels at full modulation. A radio or amplifier set
up to do this is called a 'modulator', and gets you alot of 'swing' on the
old power meter.
Just don't take it too far.
