[ARC5] If I Were a Rich Man..."T" cable fittings

[Jay Coward]

 RU/GF had multiple control capability, I think. RU-18 and -19 were multiple RX's with "chained" tuning and multiple stations unless strictly local operated?  And maybe the Army versions? Always wondered what radios were in the Martin B-10 and the Boeing B-18.

Physically backwards compatible, yes.  I have never seen any reference 
to how one would use it in the WWII command set architecture, but I 
never say never and anything is possible.

The postwar Type 12 has a *bewildering* number of control boxes, from 
C-10 to C-56 without a gap.  Included in that list are at least *three* 
to select which control box is used (C-44, C-47, and C-50)!

I have no real depth in the Type 12 system (too new for my blood...heh, 
heh...), so I'll have to refer you to the manual at 
http://jptronics.org/radios/Military/ARC12/mil_ib_arc-12_equip_1_55.pdf 
for further study.  A quick scan did not produce any BFOs (Blinding 
Flashes of the Obvious) besides the extensive control box table.

Well, I'm not so sure.  I seem to recall that the AN/ARR-15 can accept 
the control signals from the multiple ART-13 selector bus, same as the 
transmitter if I'm not mistaken.  There might be some other examples but 
they don't come to mind at the moment.
