[Elecraft] [K3] RX Loop gain setting

[Dale Boresz]

I'm using a small DEMI 6m preamp in the RX In/Out loop of the KXV3A, and 
would like to be able to inform the radio of its gain so that the 
S-meter and rx noise floor would accurately reflect the improved noise 
figure due to the preamp.  (s-meter reading would not be inflated, and 
the lowered noise floor would be evident in both the s-meter and the 
buffered IF output of the KXV3A)

Is that possible?
