[Elecraft] External Preamp & RX ANT IN/OUT

[Joe Subich, W4TV]

What preamp are you using?  Specifically, what are you trying
to accomplish?

The basic answer is: connect RX Ant Out to the preamp input and
connect the preamp output to RX Ant In.  Activate (tap) RX ANT
to toggle the external preamp in/out.

If the preamp has its own bypass relay you can use CONFIG:DIGOUT1
(and any necessary external circuitry) to bypass the preamp on
a per band basis.  See: CONFIG:DIGOUT1 in the K3/K3S Owner Manual.
