Been using the vx3 for about a year now. Still have a lot to learn. What is the best and quickest way to determine what the rx gain should be set at when hunting a new site? Do you start high and then adjust down or start low and turn it up as you can, or is there a way to know exactly where it should be set? Most of my issues are related to too much chatter/falsing etc. Also have the same question regarding the AM and Disc sensitivity as well.
