I recognize that disease; "Foot in Mouth" which has gotten me in trouble too. I'm sure the Chicks have a good side, but some of the groveling came about after the screw-up. Somehow we have to educate these nit-wits in entertainment to keep their mouths shut on certain sensitive subjects, particularly where you're a lib, and much of your fan base is conservative. The "don't bite the hand that feeds you" expression comes to mind.
Back to the subject of this thread. Give (loan) the radio to someone else, and let them give it a try. I've got a 1/2A that all my new, or crashed radios go in, if I suspect a problem.
