[Central-Electronics] VFO for 10B and 20A

I saw that advertised, but never have found a schematic.  It would have to 
rubber around a bit and I would like to see how they did it, since they were 
using different crystal oscillators on transmit and receive.  That would 
probably be an excellent unit to duplicate, using modern solid state 
technology.  There are few floating around.

Now, see if we can find a schematic.
