Help with Icom f3gs

[zane018]

So i just got myself a used f3g, i have put my frequencies in it and it transmits and sounds good. The only issue i'm having is on some frequencies i'm receiving heavy static, even when there is no one transmitting. It seems like it's a squelch issue but i don't know anything about the squelch on this radio. If anyone can help i would be grateful, thanks!!

This picture shows what the screen says when it gives static. In the manual the busy indicator says it's receiving a signal or (the squelch is open).

There is a squelch adjustment in the programming software, I don't know where it is for sure, but search around, you'll find it.

The old F-4's I used to use had a "maintenance" function. There was a way to power it up while pressing two buttons. You could then hit one of the Px buttons and adjust the squelch. I don't remember what the procedure was, but likely there is something similar for the F3gs. Likely the service manual for that radio would have it in there, or a good web search would turn up the exact procedure.

I think i have found the squelch adjustment in the program, it was at 80 but honestly i have no clue what to set it at.

It may have a range of 1 to 256, so 80 might be kind of loose. If you write down the existing value, then try it to see how high and low it will go, it'll give you an idea. It sounds like it's set to loose, so adjusting it up will likely help.
Ideally, if you can find the manual method that you can do from the actual radio, that would be easier. The F-4 allowed adjustment on the fly, much easier to set it that way.

Here ya' go, try this:

Turn the power ON while pushing the [^] and [V].
Push [P0] to switch the LCD contrast between AUT and LOW.
Push [P1] to switch the beep emission between ON and OFF.
Push [P2] to switch the LCD backlighting condition between ON, AUT and OFF.
Push [P3] to enter the noise squelch level adjusting mode. Push [^] or [V] to adjust the noise squelch level within 0–255 range, push [P3] again to set and return to previous indication.

Not sure if this makes a difference but i noticed the static is coming from the channels that don't have tones. What if they don't have tones???
