backward swing


Most cases it's too much radio drive with that one amp. Back off the RF power on the radio with the amp that back swings and see if that doesn't fix it.
 
Most amplifiers are not directly compatible with a stock legal 40-channel CB. The amplifier tends to exaggerate the carrier, and limit the audio peaks. There are two ways to fix it. One is to turn down the amplifier if it has a High/Low or H/M/L switch. This is the cheap fix, but not so popular. It limits the wattmeter reading. The other way is to reduce the radio's carrier wattage. If it's done correctly this will restore a balance between carrier and audio power and restores the forward swing that the radio had when run barefoot. But so much depends on which radio and which amplifier. They are not all created equal.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
