Joel, I am not sure if thats exactly what u are looking for, but here is some material which might help you further. The setup is not strictly for 2 x u110 rotors, but can be adapted for other simple non-feedback rotors (radio shack etc.) as well.:
Original idea, setup and software from K8DAV: http://www.k8dav.com/u100_info.htm KC2PCR's implementation with 2 U 110 rotors: http://www.youtube.com/watch?v=gHTEHUlqilk I took K8DAV's software and extended it a bit, so it works fine over the parallel port (with no basic stamp controller) and a Radio Shack rotor for AZ and a homebrew rotor for EL: http://www.youtube.com/watch?v=B-nBYvPYOy4 Some pictures: http://evolution2enterprises.com/sat/sat.html Feel free to email me if you have questions.

I have gone through all my old references and cannot find what I'm looking for. Basically, it was a setup using two U-110's (or it could have been two U-100's). The homemade controller used either toggle or rocker switches and had a digital readout of AZ/EL using DVOM's. As far as I remember, it was all manual. I remember seeing this in the back of some publication, but I cannot find it. Does anyone have any inkling of and idea what I'm talking about? 73, Joel - W4JBB _______________________________________________ Sent via [email protected].
