[Elecraft] K2/100 questions?

[Matt Osborn]

I've been through the S meter calibration often enough that I can help
question 1.

Turn the RF Gain to maximum.
Turn AGC on

Adjust R1 on the control board for a reading on U2 pin 5 of 3.8vdc.
(It can actually be 3.6 to 3.8)

Turn the AF Gain to any comfortable level.

Turn on the XG1 and set to 50uv.

Select CAL S HI from the menu.
Adjust the VFO until the S meter indicates S-9
Turn off the XG1 and the S meter should drop to zero.

Select CAL S LO from the menu.
Adjust the VFO until the first bar on the S meter flickers, then back
it off until the first bar is off.

Turn the XG1 on and the meter should read S-9, turn it off and the S
meter should drop to zero.

Repeat the CAL adjustments as needed.

I've discovered that if either CAL S HI or CAL S LO is severely out of
range, that the calibration is difficult to achieve due to flickering.
For this reason, it is important to adjust CAL S LO the first time
even if the S meter indicated zero (it may be too far past zero)
