When I was searching the garage today while doing a project, I came across a 
4"x4" circuit board that has the Twin-Tee AFSK unit that I put together in 
the late 60's. Somewhere out there buried in the pile of junque is the 
demodulator from the same period. It had a board that was about 5x6" and had 
two torriods, a couple capcitors, two diodes, several resistors and used a 
big audio transistor for loop keying. They were  all in a box 6"x4"x2". Both 
units were built from articles, I think, from 73 magazine. Not the best, but 
it got me on the air.
