Suppose I use Method 2 in the K3 Owner's Manual to adjust the Ref Cal
parameter. Should the parameter be independent of the sidetone pitch? More
precisely, were I successfully to carry out the calibration twice, using
different sidetone pitches, should the resulting Ref Cal parameters be the
same?
Chris,
If you are detecting zero-beat correctly in both cases, then the result
should be at the same frequency.

Andrew,
The XG2 is controlled for its output *level*, but the frequency is
dependent on the specific crystal.
Much better to use WWV as the reference for calibration than the XG2
(unless you have previously measured the XG2 frequency with a precise
instrument).

You have to do that with your calculator :-) .
I never can remember when to add 32 and when to subtract 32, so I use a

Add 40 first - then multiply by 5/9 (multiply by 5 and divide by 9)

C to F is fast and easy to do in your head.
The real formula is:
F = (1.8 * C) + 32
My mental algorithm is:
double the value,
subtract 10% (round it off, who cares if it is a degree or two off),
add 30,
then add 2 (if you feel the need for the

I will still use F = (1.8 * (C+40)) - 40 -- as I said, I have more
trouble remembering whether to add or subtract the 32.
Similarly, C = (F+40)/1.8 -40, so it is not so complicated after all.
Dividing by 1.8 is similarly easy to do in the head - divide by 2 and
then add 10% of the result - it
