Al; Did you try the method in the manual first to set the rotor up? I followed the manual and it worked fine.

Since the rotor goes beyond 180 on the right side of its travel I let it go until it stopped. I then visually noted how much beyond 180 it had gone, divided by 2 and brought the dial back to 360 plus the number just obtained. I then assumed the pot was at its halfway position. I made the following resistance measurements 1-2 was 209.7 ohms, 2-3 was 206.1 ohms, and 1-3 was 415 ohms. Considering the manual guess work I think that is a pretty good result. I then ran SatPC32 and attempted to park the rotor at 360. It was off, I had to park it at 341 for the rotor to actually be at 360. This is basically the same result as before when I was just going by the control box readings. I believe the resistance measurements would suggest that there is not a short in the pot (unless it just happened to be around the halfway point). At this point I am not sure what to try next 73 Al W8KHP -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida [email protected] 407-982-0446 WWW.LEIKHIM.COM _______________________________________________ Sent via [email protected].
