The Relationship Between Squelch and RF Gain

RF Gain fades the signal out when turned down...Squelch cut's out the static sound when turned up...With squelch turned up you can adjust the radio so you only hear strong stations break threw the squelch...With RF Gain turned down you still have a static sound (not as loud tho) and only strong stations can be heard...

Me personally, I leave the RF Gain wide open all the time so I can hear those guys that maybe 10 miles down the road...If I'm traveling with someone close by, then I turn the squelch up to where only that driver will break threw....

 

That's the way I always do it as well.

 

Squelch puts up a wall so weak signals won't make the trip.
rf gain is like pulling down a window shade and it cuts the noise, but still allows weak signals to come through only if squelch is wide open.

 

Ok the rf gain turns down the rf coming into the radio, you can see when you have a strong signal coming in and you can see by turning the rf gain down and the signal will go down.

Think of it as a rf "volume" control.

Weak signals are eliminated when the rf gain is turned down.


Squelch is to eliminate the noise and signals from the audio, like a variable audio switch.

With it turned down, it let's all noise and signals to be heard, with it turned up to a level where it is set at a level where the signal is not heard, it is quiet.

You can turn down the rf gain and adjust the squelch to stop the noise and you won't hear a thing.

 

In layman‘s terms, you use the RF gain when you’re sitting close by another truck (like in a truck stop), so that persons radio won’t overdrive the receiver in your radio
