It's still close to 100 degrees during the day out side and at night there is currently far more of interrest on atsc, So I've been taking my time with each step.
The bracket the dish mounts to had a slightly bent tab. If you set it on a flat surface, it would rock. I checked the bracket from the damaged dish package and it is exactly the same. Tried it against the dish and same. Seems they are not getting one of the tabs fully bent into place. It's off by about 1/16". this would pull the dish out of shape slightly when the bolts are tighten down. I have corrected that.
Got a fine elevation adjuster made for the dish. Looking at ways to make sure the dish is aligned with the rotor. The Wineguard had a wrap around clamp and a bolt that went through the rotor arm with no play. This dish is a dual crusher type clamp, so lots of side to side range. Thinking of using a framing square against the side of the motor which is flat and the square should be long enough to reach down under the dish and out along the arm.
I found some chrome stripping at Autozone, most reflective stick on stuff I could find. And I glued some cardboard to the end of a paper towel roll. waiting for that to dry now. I can put that in the lnb mount and use the chrome tape to check the focus point. The dish really flexes easelly, so i'll need to see how much the lnb arm warps the dish with weight. I'd like to try a mini-bud latter and I'm guessing that 742 is heavier then a invacom.
When i mounted the wineguard, instead of just screwing the base down to the roof, I used bolt spacers. If you just screw down, you have to play with the slope of the roof and the pivot of the pole to get vertical in both directions. When you tighten the screws down, the plate sinks into the roof some throwing off the adjustment. So instead, I drilled holes and then put long bolts in from attic side using fender washers. another set of fender washers and nuts on top along with silicone between the washers and the roof lock the bolts down providing solid mounting post. Then another set of nuts go on for the plate to set on. Those allow you to play with the level of the plate/arm. Once set, a 3rd set of nuts go down locking the plate. It holds to the roof better then screws and won't shift/sink when you tighten down or when the roof heats up. The wineguard plate is larger then the WS plate and has 6 bolts so reusing it instead so I don't need redrill. Also, the pole I made to replace the flimsy wineguard pole is the same gauge as the ws pole, only a couple inches longer. So I'm also reusing the old pole, but upgrading the pole to the tripod design by adding the 2 support rods.
I had problems when using the step command to move the rotor and had problems in general using the rotor plugin for vdr. I posted another thread about this. I took the rotor down and tried it inside and it doesn't move on step east ~60% of the time but step west works fine as does the goto functions. Don't know why.
