[GreenKeys] CV-116 dual diversity RTTY converter hookup

[Nick England]

I've had a CV-116/URR sitting around here for a long time and am
thinking about trying it out. The CV-116 is made for diversity
reception and is fed via IF signals from two R-390A receivers
connected to different antennas. It has 45 tubes (plus 2 motors for
AFC control) - what could possibly go wrong?

Is anyone using one of these? It looks like the TTY interface is
pretty straightforward with an external 60ma loop keyed to ground via
a pair of 6AQ5 tubes.

BUT -  the manual refers to needing an external "control unit" - what
does it mean by that?? Is it just a connector adapter? or?
"Because the teletypewriter output connection of the converter does
not match the input connection to a standard teletypewriter printer,
an intermediate control unit is required between the converter and the
teletypewriter printer."
