[GreenKeys] Jack Selection for TTY equipment

[WA5CAB at cs.com]

The problems with using dumb (i.e., with no switches) jacks are:

1) The only way in which you can jack two or more machines in series is by 
using shorting plugs for when you don't want them in series.

2) If you do it that way, everything runs open while you are getting it set 
up.

3) If you have a machine, convertor or exciter normally wired into a loop, 
you can't take it out of that loop and patch into another one either with or 
without disturbing its default loop.

You will be much better off if you locate and acquire something like a 
TT-23 TTY Panel.  I can't at the moment recall the nomenclature of the earlier 
one that I actually used for a few years.  looked like an overgrown TT-23.
