I am based in Ireland. I have investigated diseqc as a means of rotator control and I have generated custom messages using a windows PC

See here for video

I used some basic electronics to 'wiggle' the voltage to the rotator to generate the diseqc signal.

I know others have done this too.

I was most interested in building an XY rotator using two off the shelf diseqc domestic rotators. I chose xy over azimuth elevation for 2 reasons, one the standard diseqc dish rotators typically only rotate 1/2 or 3/4 turn, and XY is better for fast overhead passes at microwave frequency

Using the software in that video, and a couple of components you can send messages to that rotator.

I also used a similar set up to reverse engineer and send custom diseqc commands to other domestic satellite equipment equipment such as a DirecTV downconveter.

I never really completed or documented my work properly, but I have some records and the hardware.

It might be possible to modify specific diseqc rotators to travel beyond 1/2 a turn, however an XY design needs little modification. I have a non diseqc XY rotator which I have used in the past and it is superior on high passes at microwave frequencies.

I have also build other arduino rotator controllers.

Any questions please ask on or off list

Anyone in North America experimenting with DiSEqC Control for Tracking ?? https://en.wikipedia.org/wiki/DiSEqC

DiSEqC (Digital Satellite Equipment Control), pronounced "Die-Sec", is a special communication protocol for use between a satellite receiver and a device such as a multi-dish switch or a small dish antenna rotor. DiSEqC was developed by European satellite provider Eutelsat, which now acts as the standards agency for the protocol.
