I would like to use my SM220 Scope for rtty. I believe I will need a
demodulator for the mark and space separation for the h.input and the
v.input. Anyone using there scope for rtty and what do you use for a
demodulator?

I use a ST-6 and hook a scope to the mark and space filter outputs. If you
want to , you can make a simple filter out of a 88 mh coil and a capacitor
for each tone, Connect one to the vertical input and the other to the
horizontal input of the scope. It does not mater which, but I think most
use the horizontal input for the mark tone.
