[GreenKeys] And another way to do the switching in your RTTY station

[Jim Haynes]

I just remembered that in the early days of amateur RTTY - back then all
the operation was on VHF using audio FSK tones.  So some guys instead of
switching the loops had a demodulator attached to the printer and did
the switching at audio levels of the AFSK signal.  Much too cumbersome
for today's installations.

Back in the late 1950s I often got into a round table of RTTY friends
that met almost every night.  Sometimes we couldn't get copy on all
the participants on a single amateur band, so we would have one or more
stations off on a different band from the rest of the group.  For that
purpose we wanted the terminal unit to receive incoming over-the-air
signals and pass them on to the transmitter so the other participants
could copy them.
