Stewart I have a fairly good signal generator and didn't give it a
second thought as to whether doing the HAGC mod to my early K3 (serial
80) would change the S-Meter. However, the meter does calibrate nicely
and is accurate when calibrated. I've not re-checked the calibration
recently, but for what it's worth these are my settings:
SMTR OF: 016
SMTR SC: 017
SMTR OK: OFF
SMTR MD: nor

----------------------------------
Have an early K3 here and have just done the hardware agc mod, spurred
on by cqww ssb a fortnight ago :-)
Mod went super smooth but am wondering about the recommendation to
recalibrate the s-meter; is it just a precaution or is the s-meter
guaranteed to be out after the mod? Seems pretty close to me from a
quick and dirty before/after check with a stable DDS signal source but
don't have a proper calibrated sig gen to hand.
I'm not an 'S-meter slave' but wondered if I should check it when I have
the opportunity....
