[Elecraft] Bad Math Chip in my K2

[Rich Lentz]

I think I need a new math chip for my K2.=20

After seeing all of the GOOD feedback on this new calibration method I
thought I would confirm its assumptions. =20

1. Allowed a 45 minute warm-up and I can see WWV and WWVH traces in my =
MixW
water falls.  Both the 500 and 600 Hz signals alternate on being =
stronger
and both are within 5 Hz of the correct frequency.  In fact depending as =
to
whether USB or LSB is selected they are right on frequency (LSB is right =
on
, USB is off by 5 Hz.)

2. Removed cover and measured frequency at TP-2 =3D 4913.41/2  =
(oscillating
between .41 and .42)

3. Measured frequency at TP-1 =3D 14913.38/9 (oscillating between .38 =
and .39)

4. Quick math in my head tells me that if I messed with C22 WWV would be
moved by 40 Hz. =20

5. BUT, I am only off by about 4 or 5 Hz, So I leave it where it is.

6. Conclude that the Math chip in my K2 has an internal error and must =
be
replaced.
