As I have mentioned on here before, I've installed a Garmin GNC355 in my RV-6. Even though I've been flying for several weeks, I still have many questions. Question for a Garmin guru: What exactly is the function of the "OPEN SQ" button. In reading the pilots manual it appears that when "open sq" is selected it reduces squelch to zero, ie. no noise reduction.
I seem to find that when I select "open sq" I can hear everything fine. If I de-select it, I hear nothing at all - nada. I thought today that my receiver was just dead, until I selected this again and everything is fine. If this is a squelch function, how do you set the squelch level?
