To answer my question, its probably polarity. Looked at the manual for the Telex CCU, and it seems the switch would reverse and hold polarity for an incoming call, so I probably just need to reverse the loop wires.

Mine at home just works, so its wired to think its getting a call.

Are you sure it is a 60WPM (45 baud) machine? Most 32s were set up for telex operation at 66wpm. Right now the Europe channel might work because it is 50 baud but the ST-6 probably cannot be tuned to the European frequencies: 1275 mark and 1445 space. If you want to test things, I could set the frequencies for the Europenchannel to 2125/2295 temporarily as long as we warn the European users (if there are any) of the pending change because their machines won’t work. 

Let me know if you want to try that test or if you think you can receive 1275/1445

I have a model 32 connected to a Hal st-6 TU. When connected im only seeing space on the Tu while feeding it ITTY. If I unplug the loop, I see both signals on the Tu. Anyone have quick ideas?

If I reset the machine it shuts off. So i need to get it in online mode. Its a western union telex machine with 4 buttons.
