The schematics in my 1959 Yellow Book show two antenna connections. A1
for the transmit receive antenna, A2 for the auxiliary receiver. A2 is
for connecting the second receiver to the antenna while allowing the
transmit/receive relay to unhook it from the transmit antenna. I'd
expect the SO-239 to be the main antenna and the RCA the connection for
the auxiliary receiver. There is also a pin on the connector grounded
only receive probably intended for muting the auxiliary receiver. So
with any auxiliary receiver, arbitrary splits are possible.

Its possible that manuals may be available in .pdf form on line, I've not
checked for the KWM-1.
