One place I know of where the MC-203 "Tee" was used is
in the SCR-269 radio compass. It might also have been
used on the AN/ARN-7 as well, but I don't have that
manual to verify it.

It allowed for two control boxes to tune the receiver.

The SCR-269 could have two control locations, both
locations could tune the receiver at any time, but
only one box could control the receiver at any given
time.

On the BC-434 control box, there is a "Control" button.
Pressing this button switched control to that box. This
was accomplished by the BK-22 relay box.
