[GreenKeys] early RTTY

[dmm at lemur.com]

Thanks to Don House, I've just learned that the entire run of the
Bell System Technical Journal is online.  Hooray!

In poking around in it briefly, I've stumbled across a piece which 
might be of interest here.

  Bailey, Austin and T. A. McCann.  "Application of Printing Telegraph 
      to Long-Wave Radio Circuits." Bell System Technical Journal, 
      Vol. 10, No. 4 (October 1931).

The index for this volume is at:

and the article is at:

Basically, it's very early RTTY (with a couple of pictures).

Regards,
David M.
