[RTTY] 88 Mh Chokes

[Jim Hargrave]

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.
