[GreenKeys] Length of tape

[Larry Goodrich]

Hi out there.  Does anyone remember the name or call in the name of the
RTTY decoder, complete with a polar relay?  I'm not even sure any more what
it was called.  The name was W2A?? or something.  I built one in the late
1950's from scratch.  I no longer have the schematic or any of the
machines.  Probably a 15 and a 19, but it seems like I had a third one,
maybe a plain td.  Any thoughts???  Loooong time ago.  I had a nice RTTY
station, but man oh man was it noisy.  Larry W9HTK
