Actually, I hear bleedover on a daily basis.
Well, most illegal CBers with their "inbred bleedover generators" do this. I'd say 99% of those idiots making "inbred long distance calls" bleed over at least one channel.
Since CB criminals usually use Class C amplifiers, made for FM and sold as "linears" really are not linear at all. Class C amplifiers can be made cheaper. Since CB amplifiers are illegal, there are no quality control standards. It will get worse as these RM Italy and other overseas cheap brands come into the hands of people who do not know what they are using.
Couple these already dirty amplifiers to the typical CBer who has no technical knowledge who sets his radio to "all pots to the right" and you then couple the dirty splatterbox radio to a dirty splatterbox amplifier, you now get a bad mess.
Every CBer who operates illegally has no one else to blame but themselves. If an illegal CBer complains about bleedover.... tough... they do it to.
By posting this, I do NOT say the OP is an illegal CBer..... I'm just adding fuel to assist his cause
BTW: I imagine my comments will be shredded by illegal CBers. I do not care. I do not recognize illegal CBers as having any proper knowledge of radio, thus invalidating any comments. Your Mileage May Vary, Batteries sold separately
