Step 1: Get Started
Open the radio by removing all the screws. Watch for the hidden screws located in the battery compartment.
TIP: Stick them to a magnet so you don't lose them.
Step 2: Locate the Components
Step 3: Tuning Transformers
TIP: The best way to locate the one we will be adjusting, is to look for a couple of diodes closest to one.
Step 4: Get to Work
TIP: Confirm you have found the correct copper coil (one controls AM, the other FM) by touching it with a screwdriver. You should hear a change in the station.
Using your screwdriver, slightly spread out the copper coils. The station will fade away and you have just increased the range on the upper end of the FM band beyond 108MHz!
