FWIW, just to complete the catalog of loop/no loop terminal "command sets"
(though RAV was not a command set):

RAV       CBY-46102 (Beacon) and CBY-46103 (BC band) DO have loop terminals and
          switch.

ARA       CBY/CCT-46129 (Beacon) and CBY/CCT-46145 (BC band) DO NOT have loop
          terminals and switch.  This is the principal difference between ARA
          and RAV navigation receivers.

SCR-274-N BC-453-A and -B (Beacon) and BC-946-B (BC band) DO NOT have loop
          terminals and switch.

AN/ARC-5  R-23, -23A, and -148  (Beacon) and R-24 (BC band) DO have loop
          terminals and switch.

A.R.C.    R-11A (Beacon), R-10A (BC band), and R-22 (BC band) DO have BNC loop
Type 12   connections and switching relay.
