@PLjacho 26515-27855 known as low/mid/hi are the bands of 40 channels and 4w AM/FM is the power. Take the bottom cover off, cut the white wire behind the processor and move the jumper across thats how it is done or take a look at servicedocs(dot)com and search President and Johnny 3 and the mod will be there for you
Can You tell something more about a/b/c settings? How many watts?
Can I modify standard Johnny III to get a/b/c settings?
