In many rigs, to make them sound loud & proud, instead of just cranking over the ALC POT's to 100% MOD, they'll just bypass, or rip-out, the ALC function, where the limits are the supply voltage fed to the rig itself and goes into Cut-Off. Yeah, most CB'ers, especially newer ones, don't care that they maybe putting out splatter from DC to light and harmonics that could be heard into the FM broadcast band, and worst, the AM Aviation Band. Ever set a scanner to CB CH19's 5th harmonic, 135.925MHz AM? It is interesting how many stations can be heard there, if you are near a busy 4-lane. In the 1980's, this was notorious.
