[GreenKeys] What is your set up?

[Nick England]

OK, Steve, you asked for it... PERHAPS I could have made things more
complicated (ha), but my intent is to mirror the way things were organized
in a 1950s-60s US Naval Communications Station.
Something like this - http://www.navy-radio.com/shore/shore-2-17.JPG
Unfortunately the only thing running between my red and black patch panels
is 100' of wire and a rack-mounted photo of a TSEC/KW-7 crypto unit. Also I
haven't got any VFCT mutiplexed teletype signalling hooked up yet.

So here's how I am currently set up -
ITTY
ITTY audio is feeding a receive audio patch panel feeding a 48-in/20-out
audio switchboard feeding a Dovetron TU feeding a 24-loop black TTY patch
panel in my radio room. That loop is patched through one of four trunk
lines to a 24-loop red TTY patch panel in my teletype message center room.
There it is patched to an autostart 28ASR (or any of a dozen or so other
machines).

RTTY
For RTTY receive, the receiver audio (usually from an AN/URR-74) goes
through the audio switchboard to any of several TUs, usually a CV-3510B/UG.
The CV-3510B loop output feeds the black TTY patch panel patched to a 28ASR
in the radio room.

For RTTY transmit, the 28ASR feeds the black TTY patch panel which is
patched to the CV-3510B/UG transmit input. The CV-3510B transmit audio goes
to a transmitter audio patch panel where it is patched to whatever
transmitter is desired, currently an AN/FRT-70. Transmitter control is from
a C-1004 switch box mounted on the 28ASR which goes to a control
switchboard to the selected transmitter. The transmitter and receiver are
patched to antennas via an RF patch panel.
