The other day I was using my Yeasue el/az rotator just fine in flip mode with sat-pc and PST-rotator. Today trouble. In Pst-rotator If I ask for 90 the position bar showed actual 120 and it continues to show about 30 degrees off all the way to 359 where it will stop 30 degrees in advance of where

I am using reed switches for both my AZ and EL visual feed back on my newest build. I have had to slow the motors down with a PWM so that the reeds don't skip a count. Both AZ and EL are still within the speed of keeping up with ISS. You can determine the ratio of motor turns to one revolution of

I got my TechnoTrend S2-1600 the other day and tried to get it to work on a Windows XP and a Windows 7 machine. Both machines are presently out of commission because of driver issues and an array of error codes. Seems all is not as simple as plug and play with these little monsters. I don't think

I am not sure that I would count any Satellite out when it comes to emergency use... especially if I lived in some remote part of India. Or any where else that was remote. I think Gilligan and the Skipper would agree with me. That this resource may not have been used for this purpose at this point

I spent the morning replacing the cable from the G-5500 up the mast and that was probably a good thing but it did not solve the problem. After pulling the G-5500 and GS-232b out of the computer rack I found the blue wire that is in the AZ connector, a part of the factory harness that goes to the

Today while working the sats with Satpc32 the G-5500 would rotate east to west but not return with a call from PSTrotator. It seemed to get progressively worse and I would have to return the rotator to east manualy using the manual box. I checked for broken wires from the rotator to the manual box

Unless we want lightning fast antenna rotation, we're going to need some sort of gearbox with virtually any motor we're likely to find. We could gear the drive to a simpler pot as well. Gus, I used a pulse width modulator to slow my DC motor down with out having to loose a lot of power. This
