[Elecraft] S-meter was VCO voltages for 160m band??

I would recommend that you do this the other way around: adjust AGC setting
first for no decrease in level on a quiet band and then the S-meter settings
for approximately S9=50 uV. Otherwise you will mix the receiver's sensitivity
to quiet bands with S-meter sensitivity. My experience is that the following
works well:

1. First set CAL S LO as per the manual 

2. Then adjust CAL S HI by setting RF GAIN to the 9 o'clock position
(instead of fully CCW) and set parameter so that right-most bargraph is
barely turned on. I have played with various other setting such a 10, 11
o'clock, but found the 9 o'clock position to be fine. It also agrees
reasonably well with 50 uV from my generator to give S 9. 

If the AGC-setting is changed, the S-meter calibration has to be redone.
