Re the processor.  It was designed as a box that sat on top of the FT101 and
plugged into the VFO socket, from which it took power.  Leads were taken to
the spare pins on this so that the signal chain could be broken, the DSB
signal  taken from the modulator board at the point where it goes into the
3.18 Mhz I.F., filtered, turned into SSB, and then clipped. It was then  fed
back to the normal chain via the 3.18 Mhz I.F. board.  On receive the signal
still passed through the clipper giving the total selectivity of a 14 pole
filter and a slight increase of gain.

We did sell quite a lot of PCB's to Milt and he made them up as kits.  Some
people fitted the board inside the FT101 but I was never too happy with this
arrangement as they had to fit an external gain control and in/out switch,
and noise pickup and feedback were always possible if it was not done
correctly.
