[Elecraft] K3-Hardware agc mod and S-meter cal

[Dave G4AON]

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....
