I am having problems with my sporster 5 radio it will automaticaly switch to preset zero, sometimes it doesn't do it for days sometimes it does it every 2 min. and for a while whatever station it was on would set itself to preset zero and beep every 30 seconds or so like it was programing to the preset again and i could not change the station. I have it taken apart it looks like the switch that is soldered on at this point on the board is on soldered on half the pad. have you ever heard of this before? or know how to fix it? i was going to remelt the solder but it looks like it is a coated board and i don't want to burn anything up.
