It took some modification to the dish mount, but I'm very pleased that I am now amongst the group of motorized dish FTA'ers. I will post some pictures later. The problem I was running into with the Stab HH90 motor was that the dish mount was hitting the motor. I had to basically add an extension on to the original Alphastar dish mount so that the dish mount wouldn't hit the motor any more. My local hardware store had what I believe they call "mending" plates which are basically a small straight piece of steel with holes pre-drilled in them. Using 5 of these mending plates, I was able to extend the dish mount out by about 4 inches and it no longer hits the motor. It cost me probably a grand total of $9 worth of bolts, nuts, and these mending plates to do the job. Last night I was blind- scanning the Ku-Band skies with a big grin on my face the whole time. I'm quite pleased with my modified mount, but I'm even more pleased that the dish is properly tracking the arc too! I'll post pictures in the next day or two. The pictures will show exactly how I got it to work, provided that I can pull myself away from the blind scanning long enough to take the pictures.. My wife saw me blind scanning for hours yesterday and she asked me "Do I have to do scan every time I change the channel!?"
