Got my replacement AM thumbwheel radio installed today!

I just learned that AM radios have a set screw in the front under one of the knobs. I had a slotted hole in my Duster for this screw. (Don't remeber which knob it was under) You take a small slotted screw driver and change the setting on the antennae. It is called "trimming" the antennae. I will make your signal come in weaker or stronger depending on how you trim your antennae. :|
