Fw: [GreenKeys] Help with RTTY

[Gerald]

Hi again

I live in between Urbana and Springfield Ohio.



While looking through some stuff today I found a Mainline ST-3 Demodulator.

I have some picture of this at 
http://www.projectgm.com/html/teletype_updates.html

If any one has information on this I would like to know about it.

I did find an article in RTTY.com about it and will try and trace out the 
circuit to make sure what I have is the same.

Thanks

Gerald
