Jay,

Yes... SSB has it's advantages... but several disadvantages. The main
reason I stay away from SSB is the critical tuning. Somebody always
comes on sounding like Donald Duck... LOL. I spend more time tuning
people in then talking to them. And then there's the three way
conversation... where you have to tune back and forth between the other
two guys. Forget it. And last, there's alway the fact that until the
CBs reach a stable operating temperature... your tuning like crazy.
Nope, SSB is not for me... I have my DSB-SC... and it doesn't have
those problems.

Something wrong here, DSB-SC received on a normal set can only be
made 'inteligible' if it is received as SSB.
SSB is simply one sideband of the 2 DSB sends, so your BFO is [just as]
critical.
If you BFO is of center (so you re-insert the wrong carrier) and your RX
filter already removed the other sideband, then you have all the 'duck'
sound of SSB.
Moderns CB sets have no 'DSB' option, only USB / LSB, so always use one
sideband.
In case a set DOES pass both sideband, you get double the problem....

Maybe you mean something else by DSB-SC altogether? Leave SOME carrier?
