Question about Cobra 19 DX IV CB Radio
Turn the RF gain all the way up and leave it there. Also turn the squelch down until you hear white noise, then turn it up just until it goes away.
RF gain is how sensitive your receive is. The higher it is, the more range you have. There really is no need to turn it down ever, unless you are trying to not hear some one out in the distance. Normal operation, RF gain should be all the way up.
Now squelch is used to quiet non signal noise. Like white noise or interference noise, Or other radios with a really weak signal that you can't hear completely any way.
You just want it so it just quiets the fuzz noise. Depending on background interference and the amount of radio traffic, the may have to be adjusted to silence the noise you don't want to hear. When a strong audio signal is received, it will break the squelch, the higher the squelch is set, the stronger the signal needs to be to break it, otherwise it will silence it.
