I'v been using my dish for a few years now.. I have trouble getting KU band set up.. I have band set up pretty good. How do I know my dish is aligned to it's peak? is there a cband transponder i can goto and check signal and that would show me I am set up correctly?. What are typical db readings I should be seeing? example Metv on 101 West.. I see 13db of signal. I have been tweaking it off and on over the last few weeks trying to pull KU band in on it. I have started from scratch at my highest sat 81 West setting my elevation then I go to my lower sat and fine-tune my azimuth. I want to hear some input from you on what steps you do to fine tune your dish?. I really would like KU to work on this dish. My other idea is setting up a dedicated KU dish but I don't want to if I don't have to. Thank You

Hello when peaking a C band dish the first thing you want to do is to turn your dish to the highest satellite for your location. Once you have done that find the strongest TP on that satellite
using a signal meter go out to the dish and trying with your hands  lifting up on your dish to see if the signal getting any high or lower if it getting higher when you pickup on it, then you need
to adjust the elevation up, try pushing down on the dish to see if the signal getting lower or higher. If either one doesn't  increases the signal then you know your dish elevation is correct.

Once you have made the adjustments go back in the house and peak the dish using the remote east and west to peak the signal.

And only other adjustment is the declination now when doing that adjustment... YOU MUST mark your dish  current declination setting that is present on the dish. Caution with that adjustment you get that wrong you might be outside most of the day.  Let me know how that went.

as it is right now I can track 55w to 135w.. Even on 103 W I am getting 9db on PBS East. I am in south carolina. Now as far as declination goes I have adjusted it not the lower satellites for the best signal. Your saying I should adjust the declination at the highest sat as well to peak the signal on 81W? btw I am using a Cband/Ku combo LNB.. KU is universal. Edit... Declination should have been Elevation.. Typo there sorry for the confusion

No you never adjust the declination but one time, the time you install the dish whatever the dish say for your Latitude and Longitude you set it for that and that is it. Unless the Dish has turned but I would never use that to adjust the dish, just check it and make sure your numbers are correct.

I thought I set the elevation plus the declination at the highest sat? in my case is 39.5

A 10 ft dish I believe is like the equilavent (sp?) of a 3 ft ku dish for ku especially with the mesh. If you want the 16apsk feeds then you need at least 4 ft. I recommend at least that for ku now with s2 and 16apsk.

I have ku on my 10 ft dish. It gets very few s2 feeds. Stand alone would be best and works great for me. I get frustrated with ku on the big dish. Rarely use it.

Third time you don't adjust the declination except when you install the dish for the first time, or if the dish has moved...

Just try adjusting the elevation NOT THE Declination

Okay. thanks for the info.. sorry for the confusion. I have only adjusted the declination one time 2 years ago when I installed the dish. I mistyped my reply above and mean Elevation. Only adjustments I use now are Elevation and Azimuth and feed adjustments.. Mike yes i know what you mean. It's a pain to set for KU.. I am thinking about just removing the C/KU feed and adding Just a PLL Cband Feed and peak it for C..

As long as your polar offset is correct, and you are tracking the arc correctly You may need to adjust your focal point a tad. Also make sure your feedhorn is square to your dish and not tilted.
Do to the fact on a dual stacked LNBF this is very important for ku or the signal is bouncing up the throat to get to the ku probs!!
I've seen the pic you sent me of your LNBF and it is by far the worst of all ive ever seen manufactured.
If all of the above don't work for you than I would talk to RICK about a new LNBF setup.....

I've got a 10 foot winegard mesh deep dish with a C/KU lnbf and it works rather well with DVB-S2 ku-band on a stacked cheep China DMS international BSC-621...
Yes, 16psk is iffy.

I have a 10' Winegard Quadstar mesh dish with a Bullseye11 feedhorn with Norsat C/Ku lnbs like Rick sells and it  does an awesome job on both C/Ku feeds throughout the arc. This setup is a little pricey but does a great job.

I heard that Pansat DP-4 works great too and less expensive

While I certainly can't get all DVB-S2 16psk out there, my 7.5' Perfect10 with DP-4 can catch plenty of DVB-S2.

I just locked on [89.0W] 11840 - Vertical - 34285.136 - 3/4 - 16APSK (SNR: 11.8 dB, RFLevel: -36 dBm). TSReader is seeing a clean stream, no CC or TEI errors.
