James,
Listen to Dave, he is 'on target' with his post, and he is now the K2
'expert'. But it might be helpful if you post the PLL high and low
frequencies as well as the range test results.

To follow up on my question about the PLL range test, how critical is it to be
at or below 15Khz? Currently I am at 15.40Khz after playing around with the
winding spread. The errata sheet says to be between 9.98Khz and 15Khz
difference in the high and low reading.

Hello again,
Still building a K2. I got to the PLL reference oscillator range test and did
have to remove one turn from the toroid.My range at first was 20.6 Khz.
I got it down to 15.38Khz. I am worried if I remove another turn it will be too
low. I went ahead with the continued testing and all the numbers (test results)
are good.
I stopped for the night on the BFO alignment.
My questions is, is the 15.38Khz ok or do I need to remove another turn from
the toroid?
