This is very hazardous to your health.  Since it would put out
strong sidebands +/- 8 khz of your signal (and probably multiples of same)
and wipe out at least the two adjacent channels if used on 27 Mhz CB, 
thus resulting in a crowd of pickup trucks showing up at your front door 
with irate occupants.
