I own a Grant XL as well as a LT. I see no need (although it may improve the radio) to do a mod on a perfectly good radio. More equipment has been screwed up than has been fixed unless the right person does it. If myself or nvcowboy or whoever is satisfied with the radio as is ("it rocks out of the box") why jack with it? Sometimes the perfection some reach far is not atainable without first improving the piece of equipment (ie upgrade from a grant to a yeaseu).
