bought this radio to put in my new truck.. at first i had antenna warning. this went away and i blew the fuse in the radio. i replaced the fuse, did a radio check and its saying no rf transmission. i tired to calibrate it as the manual says but the cal and swr did not move at all when i turned the knobs. i was on the road today and no one responded to my radio check several times.. did i burn this radio up? what do you suggest so i can get it working like it should or fixed?
