Well I am a big believer in high counts Linux, but also think if it not broke, no need to fix it.
now I have a Ajax mount on a 10-ft CM dish an it performs flawless, it has been up an running for about a year now, with the powertech G-box V3000. an have not had to reprogram it due to lousing counts, or don't need to bump the dish east or west on ku satellites. an it doesn't matter if going west to east or east to west.
now just tuned in ABC news on G-28 ku, position #144 on G-box, an can go to 153 an still have signal but 154 an lost signal also the same #s going east, at 10 #s on the G-box signal is lost, but still gives you a fairly wide tunning area on ku, but will vary on size of dish used. now on this dish a Pan-9000 is what runs the g-box an with pansats you can not control the amount you want the dish to move like with a Diamond, Coolsat, Satopia an other receivers that I have put on the g-box. so the Ajax has 9 counts either west or east of its stored position.
now also just check same transponder on my 1.2m dish that I fabed up a gear step up driving runing a 22-magnet wheel, an on this 1 position #130 an if I go to 156 lost signal but have week signal on 155. so with this mount I have 25 counts to the east or west of you're stored satellite location. but this is a high count H to H mount from due south to east or west limits little over 2200, with the G-box.
now after using this Ajax mount, for quite a wile I would not mess with its counts, works to good. but if you are determined to add more counts I would do it like my home made 1 here with gears an with 2 screws to atach a gear to the magnet wheel in the Ajax motor, an now add a idler gear with a magnet wheel atached to it out side of the Ajax motor housing, with some kind of bracket to hold all. an this way you can put it back to stock just by removing the 2 small screws attached that you atached on the Ajax magnet wheel.
Good luck Fred, this is just my 2 cents on this here, but I will be watching this tread to see what you wind up with in the long run. should be interesting.
