[Elecraft] S-meter calibration

[Joe Subich, W4TV]

1) calibrate the subreceiver S-meter using the BNC (AUX) antenna 
   instead of the main receiver so that the splitter losses 
   do not impact the calibration. 

2) to calibrate the subreceiver enter CONFIG:SMTR SC or 
   CONFIG;SMTR OF and tap the SUB button to select sub RX. 
   RF will change to SUB in the VFO A display to indicate 
   that the subreceiver calibration is being adjusted.
