I'm in Thunder Bay with a Starchoice eliptical dish less than 30 inches across, I believe and I'm pointing it at Galaxy 3. I get about 70% strength and 40% quality. I've had no trouble picking up
Telstar 5 or Galaxy 4 but with the dish I'm using I have given up trying to get anymore quality. I'm using the second generation LNB from Starchoice and on my second dish, exactly the same, I am unable to get a lock on Galaxy 10 much like your problem. I think that the Starchoice stuff is marginal in the "great white north". I have lots of room up here so my next purchase is either a 36" dish or all out for a 6'
Cband. I'm using a Satwork receiver with the blind search feature and when its on its on but even if I'm a little off line no telling what will happen, I've had a combination of Galaxy 4 and telstar 5 all in one scan.
Good Luck
