I understand what your saying about fighting mother nature, she is a tough one ! According to several radio people I know they say the schotkey mod makes a noticeable difference and others say it doesn't so I guess it boils down to who do you believe. I have to trust these nice hearing aids the VA gave me and I know I hate static or air noise while I travel long distance so I might try my extra DX 979 as a experiment. Then we have my McKinley which is nice for my little car but needs a professional alighment to make me happy. Nothing ventured nothing gained. And yes I know about Squelch an RF Gain controls.
