Hi All Recently the tuner in my FT-450 has quit working on 80. It will tune the SWR down if it is really low without the tuner, but if it gets up to 1.5:1 it won't tune. The lights flash and go out and the SWR is infinity when I press the key. It works fine on all the other bands - just not on 80 meters. 73 Tom W7WHY
