I could be wrong here, but I'm going to take a stab at that switch. I
think it
possibly limits the 10 meter output to 50 watts.  I bought an FT-101S in
many years ago and their limit was 50w for ten meters.  Just guessing but
check the power output on 10 meters after you flip that switch around.
Only a guess !
