[Elecraft] [K3] Sub RX S-meter cal

[Ken K3IU]

The S-meter Cal procedure in the manual worked up until about v.3.15 or 
so. Now I am pretty sure that it was NOT separately adjusting the SubRx 
S-meter, but I never checked, so I'm not sure. It doesn't really matter now.

I have determined that, at least on my K3 (#202) running v3.41 et al, 
after running the RF Gain Calibration procedure and setting the MAIN Rx 
S-meter, the Sub Rx S-meter is spot on. It actually follows the 
adjustment for the Main Rx S-meter, i.e., set Main Rx at an extreme and 
the Sub Rx shows the exact same extreme.

So... it looks to me like there is no reason to have a separate 
adjustment for the SubRx S-meter. I'm sure the manual will catch up.
