[GreenKeys] Newbie setting up an m26

[Harold Hallikainen]

Welcome to heavy metal RTTY!

As others have pointed out, due to the high inductance of selector
magnets, a high voltage supply is needed (it is possible to capture the
"kickback voltage" from the selector magnet and use it on the next space
to mark transition, though is is more complex). I use a Teletype 152950
supply from RTTY electronics as shown at https://w6iwi.org/rtty/ .

On interfacing the high voltage loop to a microcontroller, I use an SSR as
shown in https://w6iwi.org/rtty/DspTU2/kicadA/DspTuShemA.pdf (see K1).

Good luck!
