Was getting the east/west feeds of RTV on AMC9, 11735H, 4444, 3/4. But three days ago lost the signal. All other sats seem fine. Has RTV dropped the Ku feed, or moved to a different sat?
Thanks for your help, guys. It was a combination of overcast sky and high wind. The wind blew the dish off the proper setting, had to reposition the dish on pole so it would track the arc properly, it was a bit off.
glad you got RTV back. they are great channels aren't they?
Radar what motor do you have on the dish that moved? My stab HH120 seemed loose one day ( i could move shaft 1/4" ) but when i moved motor all the way west and back to the reference it was tight again.
I have a PowerTech DG-380 motor and a GeoSAT pro 1.2M dish.
My motor has no play internally (gear mesh is good) nor where the shaft and the motor tube attach. However, I suspect that the movement came from where the dish assembly clamps to the motor tube.
The motor tube has a very slick finish and the dish clamp can only get so snug on it. When I first assembled my dish an attached it to the motor, I was skeptical about this connection and thought it might slip on me. The dish came with two U-bolts to attach it to the motor tube, but it had the capability to install three U-bolts, so I obtained an extra one to help secure it.
There is a small cutout (or window) in the metal of the dish bracket where the seam of the vertical axis of the motor tube can be seen. I had this seam centered within that window originally. With everything fully assembled, it is difficult to see this window and the seam of the tube without a parallax error. I will either have to use a mirror or drive the motor to an extreme east or west position so that I can see it better. This is the first place that I am going to investigate as it is the most suspicious.
If this is where my error is coming from, I will have to provide a better means to secure it.
If that's where your error is coming from, it means that your declination is changing as well as the apparent sat longitude. Any rotation on that tube will (if my mind is awake yet) increase your declination. This is somewhat similar to the darn "spinclination" on my Orbitron/Atlas BUD, ie you turn the whole dish on an angled hub to change declination, but that also changes the position along the arc AND the polarity. I liked it at first, but the older my dish gets, the more I hate it.
Anyway, that's one reason I decided to get a pole mount instead of a U-bolt mount when I bought my Fortec dish, because the pole mount uses the holes in the tube, so the holes keep it centered pretty well.
