I questioned UPSAT if the GX-60 squelch could be adjusted and was
told a blunt "NO, it's fixed. Go away."

My experience with the UPSAT guys is diefferent. They were very
responsive.

In the installation manual of the GX-60 you will find a way to adjust
the squelch.

Send me a mail if you don't have it.

I have the manual, and it is NOT in there. I wonder if it is a capability
that they added in the newer units.

What version of the GX-60 is yours? [Mine is something like 2.4]
