[GreenKeys] Looking a for a Demodulator Board designed by Eric Volpe

[Lee Mushel]

Eric put a lot of great thought into that little terminal unit. Since I 
still have ones around here including those that first appeared in CQ, 73 
and QST including the ST-6 and 6000 I thought that it was just the thing to 
put in a Polar Relay housing.   Of course, doing that was absolutely 
necessary if you were trying to pay the RTTY "dues" in the '70's.   But 
getting enough 88 mH toroids in such circuitry and limited space was just 
about impossible.   I know that Eric made more of them than he could 
immediately get rid of so I don't blame him if he doesn't care to rework 
past effort.....

Good job, Eric.
