[GreenKeys] Extel Information

[Sheldon Daitch]

For some literature on the Extel line of teleprinters, see:

   http://www.billcope.org/extel/

Bill was so kind to scan and post his file copy of some
Extel literature, and he, too, was disappointed to learn that
the Extel name was not for ex-Teletype.

The last picture is of the Extel Commaster, that we used to
replace the M-28 machines.  It was taken at the Munich
receiver site, which was actually near Uberacker, about 20 miles to
the NW of Munich (M�nchen) headed towards Augsburg.

Behind the Commaster are portions of two RCA SSB-R3
ISB receivers which we used in the good ole days of HF broadcast
relay.
