I'm just at the point of testing the PLL Reference Oscillator Range as 
well and am measuring 9.11 kHz.  This is low compared to the spec of 9.8 
to 15 kHz per the manual.  Before I proceed to much farther, is 9.11 kHz 
okay as is?  Should I be getting a 12 uH replacement L31 as well?  What 
is the downside of leaving it as is?
