[GreenKeys] In search of AP or UPI nameplate

[W2HX]

I have a (two?) western union "black box" ticket tape machines (5A? can't recall). These use a very similar print mechanism to the model 20 and also uses 6 bit. Jack WA2HWJ (W7TTY?) got it working for me at one point, but I never did anything with it (them?)

Interesting! A model 20, which uses the 6 bit Teletypesetter code (
https://en.wikipedia.org/wiki/Teletype_Corporation#:~:text=%5B31%5D-,Model%2020,-(1940)
).

The 6 bit code is described at
https://www.smecc.org/teletypes_in_typesetting.htm#:~:text=Here%20we%20see%20the%20Teletypesetter%20code%2C%20presented%20on%20a%20handy%20pocket%20%22ruler%22.%20This%20is%20a%206%2Dbit%20%22superset%22%20of%20the%205%2Dbit%20teletypewriter%20code.%20The%20added%20bit%20is%20designated%20%220%22%20to%20fit%20in%20with%20its%20placement%20across%20the%20six%2Dtrack%20perforated%20tape.

It's interesting that this was used by a radio station. I thought most stations used model 15 with its 5 bit code. Are you sure it's a model 20?

If it is indeed a 20, I could look at doing a 6 bit code version of https://w6iwi.org/rtty/audio/nyt/ .
