[GreenKeys] rtty tuning systems

[Eugene Hertz]

Under the topic of dead-horse beating...

Thanks to James Tanton, he scanned a 5 page portion of a 1975 ARRL publications on specialized communication techniques - tunning rtty systems. Very interesting. Hope it is useful to someone, I know it was for me.
