Close, but works differently. That switch unhooks the internal receiver
from the TR diodes so the receiver can use a different antenna. Like
listening on 160 with a Beverage and transmitting with a dipole or
vertical. But you could hang the second receiver on that Receive Antenna
jack and close the separation switch and run the two receiver front ends
in parallel.  Or by unhooking one wire at the LL driver board, only run
the external receiver. Much easier than the external relay, you still
need to use QSK or Tr outputs to mute the second receiver. My manual
suggests simply connecting the second receiver to the Receive Antenna
jack, it doesn't discuss control of the second receiver.
