How to change actuator motor count on a 36''arm ?

jackpeas1 · #1 (**permalink**) 08-18-2003, 07:30 AM

Hi Guys, My motor count is to high 50 to 60 motor count per 2deg. I need to get down to 24 per 2deg. My system is 4dtv922&920,monterey95,10ft solid dish,2c&2ku feed,2fta receiver,dbs lnb. Thank you jackp N Chicago

you can always remove every other magnet on the indexing wheel. I've heard of that a lot over the years, and my local sat dealer even recomends this on high count actuators when using with a receiver that can't keep up with the count. ( 920 or 922 4DTV).

Hi Spyder, Thank for the reply.Is there a website for this info?This is a new arm, and the arm before this one was doing this.Thank again Jackp n Chicago.

I'm not aware of any site with any info on that, sorry. I'll dig around and see if I can gather some info.

What brand actuator is it? I didn't think any were being made anymore with that high of a count, other than the heavy duty commercial types.

From what I've been told it's a fairly simple procedure,although I've never personaly done it.

Hi Spyder,My last2 arms were Venture. Idon't know how to remove the magnet.I am tring to get down to (P-9@58deg). For my fta receiver.Its a lot stuff in that gear box. Thank big guy. Jackp n Chicago

Hi Spyder,I have a 24'' arm,the count is the same as the 36''arm.I am trying to get to 58deg P9 For my fta receivers. Let try tell you about my system. 4Dtv922 &920,monerey95,2c&2ku lnb ADL feed with dbs universal lnb dual port, solid 10'ft dish.All this is on the big dish.That 6 cable 120'ft long.The mini dish(directv dish) and receiver,dish network receiver no universal lnbf as now.2 more cable 120'ft total 8. I am getting a reading 95 on thr directv receiver. I am not getting good reading on dbs on the big dish. Is there a difference between the elevation on the big dish and the little one? Thank jack n Chicago

I really don't know too much about the little dishes to be honest. I've always done the bud. Someone may want to jump in a shed some info on the little dish setup here. ( hint, bobkat)

The elevation settings are 'mathematically' the same, but i think the little dish has an offset adjustment allowed for on the setup markings.

The settings on the big dish are taken directly on the dish hardware itself.
In your area the elevation setting (the main piece the dish ring attaches to) should be about 42.65 degree..... the declination offset (the dish mount ring) should be 5.85 degree difference, tilted downward. You can refer to this site: http://www.geo-orbit.org/sizepgs/tuningp2.html for some great setup advice. I really learned a lot from there. section three covers what we are discussing.

Just curious, is the high count causing the receiver not to be accurate in it's positioning?

Forgot to mention earlier: all those settings should be made with the dish at it's highest point in the arc, or true south.

Hi Guys, My southmost sat is AMC3-k3@87deg.With me being Chicago my zip code 60643 6606, 41.6 lat north and 87.6 lont west. My little dish receiver is all over the place with this reading. Like I said I am getting a95 on the little dish.That why I wan't to get a universal lnbf for my mini dish. I can check this out with my dish network receiver.(check both directv and dish network rec. on one dish, maybe at the sametime.) I called jim (the guy that make the sat-set,canary, the alignment tool man. Sometime back talk to him on the phone and by email. I got his alignment sheet with info. I have been to that geo-orbit site, many time, made copy of it.But just don't click for me.Just a few books (world satellite yearly,the hidden signals,world satellite almanac, and more.I think my declination is of on the big dish(DH SATELLITE Dish) thank guys Jackp N chicago

Hi Spyder,From w7 to w9 they seem to be good, But I know something not right.after amc9 @85deg I dont get anything with the 4dtv .Maybe because of the trees on the east end. That why I need to align this dish now,so I can be ready when winter come.I have been playing around with this dish almost 2 years .Its DH SATELLITE dish 10 footer.I can pickup k5 @79deg with my fta receiver. Now back to your question about the motor count.On the west end it don't matter about the stroke. But when I get to the east end two thing are happen, 1 I am losing stroke because I have come a long way. 2 the sat are closer together. But they are still 2 deg spacing(some of them) Thank big guy jackp n Chicago

If you're getting good reception from w7 to w9 it sounds like you are pretty darn close. I would try the simple lift up/down technique on the dish and see if you notice any signal increase.Then adjust slightly according to axamples given at the site mentioned earlier if needed.

Do you have ku on the 4dtv-big dish? If so can you get PBSX on k3 channel 600? If you can get that then I would say you were pretty close on setup.

When receiving k5 @ 79 on the fta receiver, is it on the same dish or a little dish?

There's an anolog channel on # 24 c band on w6 @ 72deg you should be able to get on the 4dtv unit. Other than that there's not a lot there until you get to P9. Not a lot there either for the 4dtv, but you should be able to lock some digital signals to confirm where you are.

As for the count: as long as the receiver is positioning the dish correctly each time it moves from one sat to another, I wouldn't worry about it. The higher the count the better the accuracy in pinpointing the strongest signal.You can always reset the e/w limits in the receiver if the sat you are looking for is outside of what is programed.

Hi Spyder,My fta receiver is not connected to the little dish.I don' have any programm for it yet. My little dish I don't reaily want to move it( its looking @ 101 directv)that why I am go get a universal lnbf lnb. I can get 2 satellite at sametime(directv @101 and dish network @110 on the mini dish) Now when I reprogramm the 4dtv, I do master reset.I do it from sat- GO- 9. After all the sat are back in the sat- menu,I can start programing them in. I try find a sat both end (C4 andW3)so the receiveer would know where they are. The next sat is G1 sometime the number are wrong.So I do it manual.The motor count is the number from C4 to G1.Go is first sat to be programmed in.Sometime my receiver give me number way out(40 motor when its should be 50 or 60) and then I used the signal meter on screen.I get K3@87deg 600 pbs,K9-19,L4 the pbs ch,I am not getting K1@103-780the digital ch, Nothing on k1.W1 is very good.Than big guy jackp N Chicago

Good advice Spyder... :wink:

This thread is way too geeky for me -- think I'll just lay low...
