my FT-102 has a switch on the back labeled external receiver and my
TS-940 had one as well.

Michael, that's basically how it worked. Although I never used the
external receiver option, my old Swan 500CX also had that capability.
So did the Drake TR4.

No. You could do that if you wanted too, but you would then have to
come up with a way to switch the second antenna to the external
receiver, and remove that antenna during transmit. That could easily
be done with the proper relays or electronic switch, but most people I
knew just used one antenna.
Some rigs only provided the contacts to power an external relay that
could be added for that purpose, much like the switching relay for an
amplifier.
People would often use a separate receiver rather than buy an external
VFO, especially if they already owned a decent receiver.
