[QUOTE="2old4this, post: 5896, member: 174998"] I think you've answered you own question by saying you need to restore the satellite positions... It sounds like it's not the signal that's being lost but rather the dish is not moving back to the correct position. Is that actually what is happening? IE are you having to realign the dish (physically move it) to pick up the signal again? There are many possible causes of dishes not moving to the correct positions: pulses being lost, or noise causing spurious extra pulses, both due to poorly insulated cable; or dish motor bearings being worn/sticking; or the mount having too much play in it; etc., etc. There are reports that the positioner in an Echostar 2500/2510/3000 can get confused of the dish moves at variable speed across parts of its arc (perhaps at some position on the arc there is extra resistance in the bearings). Cause can also be that the sensor in the motor which sens pulses to the positioner is malfunctioning. Reed sensors are particularly susceptible to this (eg due to wate ingress). 2old [/QUOTE]
