I'm in Northern VA and can't find 97W even following exactly the Elev, Azimuth, and skew degrees that show from the dispointer software. My set up is a 36" Digiwave dish, Digiwave Linear LBN (with NF=0.5) and Mercury II. Signal=40 and quality=0 :mad:. I think the lnb is bad. Any suggestion?

Regards,

What are your Reciever settings? What type of LNB are you using?

I got a standard Ku LNBF DG780 from Digiwave (RF=11.70-12.20Ghz; IF=950-1450Mhz; LO=10.750Ghz). Following is my receiver setup:

Sat= Glaxy25 Ku 97W
LNB Type= LNB 10750
Positioner= Off
Transponder= 11966/H/22000
0/22khz=Off
Switch= None
Input= None
Port=1

Do you have a Diseqc Switch in the line? If not the Port should be OFF. It would be very Rare for the LNBF to be bad, although it could happen? Most likely your L O S (line of sight) is not right, or some Menu Setting is Incorrect...
Good Luck..!!

Thanks Voomvoom, I have no switch (just directly connect from LNB to receiver using quad-shieled RG6). I believe Mercury II does not have an option to turn the port off. I spent 4 hrs to twist and turn the dish yesterday but whatever I did the signal was only 40 and quality was zero.

The elevation markings on some dishes are not totally accurate (as others here can also attest to), my first dish (a Fortec Star) was off by about 4 degrees . Raise your dish by a couple of degrees, slowly scan side to side, then raise the dish again and repeat.

For owners of Mercury II receivers, is 40% for signal normal when not on a satellite (or does it suggest a power to lnb problem)?

You numbers look right

I checked you numbers and they look correct.

Here are some suggestions:

1. Use a systematic approach - - - by that I mean set the skew and forget about it. Start a bit high on the elevation and work the azumuth back and forth in very small increments. Then lower the angle one degree and try again.

2. One time my 9 year old helped me by using a Walkie - Talkie (I was on the roof and he was in the house watching the signal from the receiver)

It can be very frustrating when you cannot find the satellite but I have found the systematic approach to be much better than a random method.

Lastly, since DirecTV has signals at 101W and 93W if you have an old LNB from DirecTV you could find those two and then go half way in between. This sometimes helps since DISH and DirecTV put out so much greater signal than Ku band.

couple issues
-DirecTV isnt at 93
-DirecTV uses its own type of coding. Its not DVB so even if you are aimed at 101 you cant get the DirecTV sats
-ExpressVu is at 91....that is a thought

Yes, 40% signal strength and 0%-1% signal quality is what I usually see when not on an active transponder. It doesn't prove you do not have an LNB problem, but it doesn't prove you do, either.

I agree with chappelrun. The systematic approach has worked for me time after time. I have the best success with a Mercury II. I usually find G25 in less that 25 minutes, from pulling out of the motor home until fully tuned in -- until the tin dish warps again. Will be transporting a Primestar from now on - I could not get the warp out nor lock on in Seattle - tried for 6 days. Is the digiwave a fiberglass dish?

Thanks for the information, was wondering because with my Pansat when I connected a Star Choice Dual LNB/Quad Output to my 8x1 switch they wouldn't play nice with sharing the power and the signal strength showed 34% (normally 60s and above) and it wouldn't work (workaround was putting a 4x1 switch before the 8x1 and putting the Star Choice LNBs on the other ports of the 4x1).
