What is more an issue and a problem is that most CB grade audio
compressors and clippers are not properly band limited. throwiong the
full audio spectrum from Dc to 20KHz. and beyond is an often mistake
made. A simple look at the standard equation for Double Sideband Large
Carrier AM signal it becomes self evident that the wider the frequency
spectrum of the modulating signal the wider the bandwidth of the
sidebands are.

If you really want to trash your neighbor's CBs for +/- 20 or so
channels, just open the bandwidth of the micrphone amp and audio
string in front of the audio power amp that delivers the power to the
modulated stage. Say an audio spectrum from Dc to 40 KHz should do the
trick. Then to really splatter just increase the modulation index to
around 2. That should give you a signal that should easily occupy
about 400KHz of bandwidth.

All this can be done with a carrier of about 10 to 20 watts and you
can be heard on all 40 channels for a good five to ten miles radius.

A good band limited mic amp with some compression and/or clipping will
help in improving signal to noise ratios of about one to two dB at the
recieving end. Audio clipping and compression do very little to
improve signal to noise ratios. They do help imensely in increasing
bandwidth when not properly use. CBers think that loud is better and
even more louder is even more bettter. The problem is when you have to
heavily a modualted AM signal that is fed into an amp the is driven
into class C region, the resulting signal is a nightmare at worst. The
resulting signal occupies so much bandwidth and then the desired
signal to be received is so crappy sounding, most people haven't the
guts to tell someone that their signal sounds like crap. It seems that
the crappier the signal sounds the better the signal report. The
farther the s meter swings to the right the better the signal. Doesn't
matter if it is not intelligable.

just my thoughts.
