[R-390] Need Info on antenna Coupler

[Paul H. Anderson]

The CU-286 is controlled either manually, or by the C-974 controller,
which seems to be the hard part to come by.  Hank has all the pieces but
the cables (William Perry "the connector guy" has all the connectors).

The autotune in the CU-286 is very similar if not exactly the same as the
R-391.  The power for both come from the PP-629 28V power supply.

The C-1012 is (I think) the triversity receiver controller, and monitors
and controls the AGC from three receivers as opposed to the 2 that the
C-975 does.  As far as I know, it doesn't have the outputs to control the
autotune on either the CU-286 or the R-391.

The unique part of the C-974 that controls everything is a motor driven
servo/relay unit that is a fancy state machine for decoding channel and
rack system control pulses from the dial on the face of the C-974 (local)
or the remote C-973 controller.

I've got most of the pieces, but am looking for a CU-286 and the C-974 to
buy or trade towards.
