Chuck, I followed you procedure and was able to pull it back to within
11 Khz, then the knob quit turning (was turning to the left). I had
the radio on 15,000 Khz. Turn the cal knob all the way to the left and
all the way to the right and was not able to hear the tone. Then I
turned the cal knob back to 14,089 and could hear it, but that's when
the knob quit turning. What does this mean?
