[Elecraft] S-meter calibration

G'day,

I have been trying to perform the Sub-RX S-meter calibration and find that 
following the procedure in the owners manual (D1 p50) doesn't work, at 
least for me.  There is no way I can display the Sub-RX S-meter reading 
and enter the Config menu options required to calibrate the Sub-RX.  The 
display keeps reverting to the main RX.  Confirmed by the display 
responding the main  RX RF gain control.

The radio is loaded with 02.67/01.96/00.02 firmware.

1.    Main RX calibrates OK. (XG1)

2.    Enabling SUB drops the S-meter reading on the main as expected 
because of the passive splitter loss.  I would assume that calibrating 
with the Sub-RX sharing the main antenna path the CONFIG: SMTR OF would 
need to be adjusted to match the S-meter reading of the main RX, not S-9. 
Using the AUX input for the Sub-RX has its own calibration issues.

Don't get the idea that I'm coming on all anal about the S-meter, I would 
just like the two RX path readings to match +/- not too much.

Regards,
