You had it fixed, but then you broke it again. After doing the 
alternative method on page 49, when you tune in to 10.0000 MHz in CW 
mode, you should hear a CW note at the same frequency as your PITCH 
selection.  I presume that is 400 Hz.

I got an extremely good score on last year's Frequency Measuring Test 
using only that alternative calibration method.
