| 13. | SQUELCH - makes the radio's reception more or less sensitive. Adjust this knob to eliminate background noise when you are receiving no transmission. Sometimes if a transmission is coming in weak, adjusting this may help - though it can also introduce more background noise which may drown out the weak transmission. |
Here is a depiction of a typical VHF Marine Radio.
Some of the controls are obvious, like the volume control, some may not be quite so obvious, such as MEM /UIC. MEM is probably Memory - but what the heck is UIC? Obviously the radio you own or will own is going to look different from this, so you'll have to (groan) read the instruction manual. But maybe this can help get you started with the basics.VHF Radio Controls
