[GreenKeys] TU replacement

[John, W9DDD]

Yes I saw that one.  It's a shame that happened.  I guess he never made 
it public domain once he decided to pack it in.  (Perhaps disgusted 
enough to not do that?)

I did run into https://www.ele.uva.es/~jesus/rtty/index.html which is 
simple enough to try and modify.  Unfortunately I haven't kept up my C 
programming skills.  Too bad PHP and HTML doesn't work for DSP.

I don't see even a pirate copy on the internet. Wonder if you can run 
DOS on a Raspberry Pi?  A linux version of something would be my preference.

Ich habe dreimal abgeschnitten uns jetzt zu kurtz. (I cut it off 3 times 
and it's still too short.)
