    Many CB radios have an internal speaker, especially if they are designed to be handheld or mounted in a vehicle. Some base station CB radios also have an internal speaker. In many cases there is also a "headset" jack, and inserting a headphone or headset will disconnect the internal speaker.

    What is the purpose of the squelch and the RF gain? And how do I use them?
    Community Answer
    Squelch is used to filter out background noise, typically you would adjust it until it just starts to cut out the background static, the aim is to be able to hear voice clearly but not static. RF gain is a means of boosting the received signal and is useful in areas where you are getting poor reception to try and get a signal, but it will increase background static received.
