Yeah, yeah, yeah, blah, blah, blah.......... So whats so bad about tinkering on ones radio? I like to experiment... Sure i've blowed up a few radios in my time but its how i learn. Its how i roll man!
LOL, then why ask, go for it. I'm just trying to keep it real. Since you already did a 77 then it should be the same for an 88. The Galaxy 77,88, & 99 final section was the same.
As far as the 200 more watts comment.......that all depends on what the first wattage reading was. If you were at 100 and you improve to 300 watts then YES WOW, cool. People will notice.
If you were at say 600 watts and you made the MIGHTY jump to 800 watts GUESS WHAT? .....................NO ONE will even notice..lol. But if you like seeing that number on your watt meter then you can feel good about it at least.
