As I reported, yesterday I have a FT-736R on its way to me and been reading the manual and looking into computer control.

I already have several USB/RS-232 conversion cables so I am disposed to build the ckt shown in http://www.mindspring.com/~n2wwd/html/body_doppler_compensation.html on a breadboard for a test.

I have SatPC2 installed.

I also have a Unitrac-2000 which uses a parallel port I/F and a computer I was going to recycle that has a 25-pin parallel port. It is set up to I/F the B5400 rotator. I will have to research it to see if it will interface the radio CAT interface.

Looking forward to getting back on the sats.
