Would a motor control work? There is a device, I cannot recall its name, but I also think there is a design on Nick’s site. Jack Hart (SK) had designed a circuit. I might be able to find it.

Well my idea is not to do this 24x7, but just as a demo from time to time, but still without it being powered on all the time.

You need a relay to bring the teletype up. It all depends on how you are receiving the broadcast as to how to set that up.

 

I would not suggest having a 33 on autostart. They are not very robust machines, and are best saved for live demos and interactive usage in my humble opinion.

I see on the RTTY page it says “Most users have configured their mechanical teletype machines to power up when receiving a broadcast and the power down after the message is delivered.”

 

How do people do this? I have a Model 33 ASR and I don’t like to leave it switched on for long periods.

 

Thanks
