Hi Tom,

I have a full spec ST6000 on shelf since years.
I must have the manaul some where.
it will take a couple of days to locate it.

RX out is RS-232 compatible
you just have to make a special cable with DB9 at one end & a Molex
connector at the other one.

The demodulator is extremly simple just one 741 op amp per tone filter !
look here for some pictures
