[Elecraft] K2 Glitch on Field Day

[KJ3D]

And one more... particularily useful for getting a quick and dirty estimate.
It turns out that 61 F = 16 C and 82 F = 28 C.

There is also the conversion I use because I never can remember when and
where to add or subtract 32 degrees without thinking about it.

Both scales coincide at -40 degrees, so simply add 40 degrees to the
temperature to start with, then multiply by 5/9 or 9/5 depending on whether
you are converting to a smaller (F to C) value or a larger (C to
F) value.  After doing the multiplication, subtract 40 degrees and you are
done.
