[QUOTE="ruasonid, post: 1075536, member: 414092"] I just noticed the motor I removed has M2 on it. Not sure what has changed. I'll have a look at the old motor and if it can be made serviceable could install another dish facing South/East. Is there anything out there (I could probably go to a 90cm dish or 1m max)? During installation of the new motor I tried to keep the position of the brackets as before. I'm pretty sure I had a good southern polar orientation by line of sight (using a compass there is a large fir tree pretty much in line), or so I thought. I checked over the bracket angles and found declination slightly out so I set as correct by calculation. I found a good signal on 28.2E so tried to fine tune that using the set top box (Blackhole 3.0.9). I found that the fine movement would sometimes jump too far. The other thing I noticed was when the dish went to 28.2E there was quite a good signal (89% SNR on a cloudy day) but when I went to positioner setup the SNR dropped. On pushing the fine movement the SNR went to zero and even with movement in the right direction did not come back. I had to leave that menu option then go back in to see the effect of the movement. Finding this tiresome I went back on the roof and hooked up the tuner at a nearby window with a small TV. I though this would make it easier but there seems to be quite a bit of spring in the brackets and on tightening they pull the signal quite a lot. I could not get a fine enough adjustment not could I get the signal up above 49-55%. I'm wondering if the old declination angle was set on a meter and whilst it was not correct by calculation worked better. I'm getting into a bit of a mess here. What would be the best approach to get it right? [/QUOTE]
