Hi Don, On pg. 59 of the manual, it states:
"*This menu entry normally sets the main receiver squelch value (**0**-**29* *). If VFO A is rotated fully clockwise, the parameter changes to **=SUB POT **. Squelch for both main and sub receivers will then be controlled by the SUB RF/SQL knob, and both main and sub RF gain will be controlled by the MAIN RF/SQL knob.* * * *Note: By default, squelch applies only to FM mode. Tapping [1]** **while in this menu entry alternates between **SQL=ALL **(all-mode squelch) and ** SQL=FM**.*" If you want to use squelch in all modes, you'll have to tap button [1] while in the SQ MAIN config section. 73, James K2QI On Sun, Nov 21, 2010 at 2:12 PM, <[email protected]> wrote: > I have enabled the ability to change the sqelch settings to try and > reduce some of the background static.
