Recieve

In testphase I'm a bit struggeling with the possibilities of my MGL6: and just because there are so many possibilities to adjust I keep thinking I'm the one to get the results better...

Receiving ATC isn't always that good.. Would it make any difference to attach a larger groundplate to the antenna?
And if so, inside or outside the fuselage?

KitFox IV, antenna under belly attached to welded groundplate, coax to radio up front.

Any ideas more than welcome!

Good common ground, squelch at 3 i dont have filter turned on , insulating washers for head set jacks mounted in panel
