[GreenKeys] Brecom system

One consequence of this was that, after the system was scrapped, the "FCC"
released a large number of URA-8 FSK demods that made their way into the
MARS distribution channels.

Can you put approximate dates on this?

There was a later set of experiments.  IEEE Transactions on Communication 
Technology, August 1967, article by Selover, Griffith, Martin, and Spector 
titled "Use of Commercial Broadcast Stations for Emergency DOD 
Communications"  They used frequency shifts of +/- 18 Hz and 100 wpm 
operation.  Hmmm - they refer to projects RESTORE and BRECOM.  They show a 
network in New York, Pennsylvania, Virginia, and that area.  The testing 
was done May 1965 to June 1966.

Now I remember the late Merrill Swan telling me about such stuff, probably
in the early 1960s and he was talking about a Los Angeles station I think.
