So, this may sound weird. When ever it is about to rain and the air is humid my FM/AM functionality goes to ****. I mean it crackles and the volume sucks. Overtime it typically comes back strong after it warms up or sort of dries out. Bright sunny hot summer days no problem. BTW, the Weather Band function never has this problem. In fact if I play the weather band for a few minutes and then switch to FM the FM function works for a minute or two but then crackles and fades out until things dry out again.
