[Elecraft] K3: New Utility: S-meter calibration

[ab2tc]

I am sometimes finding it will read 1 bar above what it should, which is what
you are seeing. But using the AT1 step attenuator, I find that it takes only
1 or 2 dB attenuation to bring the reading down one bar. This now one heck
of an accurate S meter. I now have within a couple of dB at the S3, S9 and
s9+40 calibration points that I can do without fiddling with the attenuator.
