[GreenKeys] RTTY Answerback Unit

[Steve Garrison]

And you are right, it would not be limited to the number of characters on a mechanical answerback.

 

And before anyone responds with why waste one of Eric’s boards on such a small task.  I had a couple, it was simple, and it WORKED!

Hello Greenkeys folks, 

One of the essential features of a machine for use on i-Telex is that it has an answerback unit and I know that a workaround has been developed by the designers.

Unfortunately not every machine has this installed or making the wards is a somewhat exacting process that is beyond the ability of those of us who do kitchen table engineering! 

I was thinking how hard would it be to make an electronic device to perform the function.

Has anyone had experience of building an electronic answerback unit that could be initiated on receipt of the code. 

In building your own, I don’t think there is any good reason why it couldn’t have more characters than the normal 20.

I wouldn’t be surprised if someone has written an article in one on the various magazines.

 

Any ideas?

 

Alf, G3WSD
