HH100 speed

[antare]

Has anyone notice this on HH100. It seems move faster when going east than when going west. I tried it with 2 consecutive location sats going back and forth between them.

Were you using both H tp's or both V tp's? H tp's move faster than V's. Being H passes 18v and V passes 13v. So if you were driving to an east sat on a H transponder and to the west on a V transponder then yes it would be slower to the west. If you reversed it then it would be slower to the east.

I'm curious. Are you using USALS or DiseqC1.2 ? I've read some people posting things about the motors in some cases going to zero then on to a sat, which could make it faster going one direction than another, although I've never noticed mine doing that yet.

Also, since you're in Toronto, I'm assuming that the sats you're going between are west of you, meaning that going east is up-hill for the motor?? Or were you going between sats to the east of you?, in which case west would be up-hill? I know with my big dish, the motor is MUCH slower going from like C3 to AMC3, because it has to lift the dish, while going the reverse direction, the dish is falling by gravity pretty much. However it sounds like you are defying gravity.

However, there is a third possibility, which really seems more likely to me. And that is, when you go from one sat to another, is the receiver setting the LNBF to the same polarity? If not, it might be that the default channel going one direction might be one polarity, and the other polarity going the opposite direction. This would make the voltage available to the motor more in one direction than the other.

I have tried 2 sat pairs with same results

1- From AMC5 to AMC3 and revese
2- From AMC5 to IA5 and reverse

choose AMC 5 because it is is my true south = my zero position on the HH100
I am driving the HH100 with Disceq 1.2

Same polarity aiming 12182 H on AMC5 NYN2 to 12145 H Montana PBS on AMC3


Could it be the LNB ?

no the lnb does not have any affect on the motor speed.these motors are just not very fast.as Bill mention earlier could just be the help gravity moving in one dirrection compared to the other.
