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

[stewart rolfe]

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....
