Arc alignment

I take this from big dish people. I tried it yesterday with a small dish and it worked great. Instead of setting motor elevation and holding true utilizing declination (Dish Elevation) to peak the signal I set the declination and peaked using the motor elevation. I tracked great the first pass through the arc.

I took a dish down to 0 that was running to see how long it would take to get it tracking with simply backyard type equipment for tuning. Once the declination was set at exactly what the site here states I zeroed it to true south and then peaked for signal utilizing the motor elevation. I tracked from 30 to 123 with no problem except a little weak signal in spots. I raised the motor a half degree or so and hit everything strong.

I am going to use this method on my next install just to see how well it works a second time. Another note from big dish people is once all the way out to your sat (either way) push up and pull down to test signal strength. If you check each side of the arc and have opposite readings. Up on the west makes signal stronger and down on the east. Move the dish slightly west on the mast.

Same goes in reverse. Everything I have read states leave declination alone and use elevation and east west movement. It worked wonderful for me the first time out.

Are you able to decode the Irdeto signals? Can I do that too with my Invacom QPH-031 LNB and my Coolsat 4000 Pro or my Pansat 2700A? I've been frustrated cause I get good quality on some Irdeto channels but I can't decode them. Thanks for any tips or comments. Oh yeah, I have a 90cm dish with a STAB motor.

Irdeto is an encryption. It requires an Irdeto capable receiver (either a CI or embedded) and a subscription to the channel. Same for Nagravision, Conax and a handful of others. Programming (premium) is scarce in the US at the moment but there are a couple of providers. Non English channels though to the best of my recollection.

I have an embedded Irdeto receiver that I do not have hooked up at the moment but plan to just to see if it is similiar to DigicipherII. Some channels are clear with the correct decoder and some are pay. Just a theory I have yet to investigate.

Tried this and it works Great....

Sooo much easier than previous ways. Tracks the arc all the way.
Thanks. I think others will find this method a lot easier and will help all new people in their set up.

So, put my dish elevation at 0, then use the motor elevation ONLY to hit the bird? Is this correct? Can you elaborate at all? I'm about to put up a 76cm Winegard with a STAB HH100. If this is easier than the alternate method, please fill me in with more detailed instructions

Could you please one more time explain. For me I have to set the dish elevation 23.6 as per the calculations. I set my motor elevation same as my latitude (41). What I am getting from your message is:

You set the dish elevation angle at the dish as per the calculations (in my case about 24). Then you zero it to your true south (in my case 74W). Then if the signal is not strong enough, you move the motor elevation up and down to peak the signal(is this correct?). They recommend to peak the signal by moving the dish and motor together around the mast.

Please let me know if I have understood you correctly.

Thanks

The answer is you do both,if you are not lined up to your true south you correct thisc by turning the motor east/west.

Dish elevation is to be set to whatever it calculates to for your specific setup. Big dish mentallity is declination (dish elevation) sets the shape of the arc and elevation (motor elevation) sets the location (higher or lower in the sky) of the arc. East / West location on the mast must be true and the mast must be plumb.
