Art,
You are waking old memories.
I still have a home brewed RTTY TU which I built back in the 1960's for
a model 15 RTTY machine.
I built the TU inside a small 2" AM monitor scope. I used88 Mh telephone
chokes for theThe Mark / Space decoders.
Mine is still operational. I no longer use the TU section, but it still
makes a nice RTTY XY monitor.

do these have any more value as during the RTTY hardware days?
If I remember the use was for 170 hz shift with the old St -6 type
demodulators.
