Arlo,

this is what i'm doing:
I have an ASC-1 and an OSMIO-4K. I have Linear C-Band in the normal spot, with Ku and Circular C-Band on each sides. They are all connected to a Diseqc 1.0 switch.
In the ASC-1, I have separate entries for C-Band and Ku-Band for the same satellites. This is critical since they will be received on different angles of the dish

In the OS MIO 4K, one LNB entry is set for Linear C-Band, one for Ku and one for Circular C-Band. Each satellite entry is set to the appropriate LNB entry, with the diseqc setting matching the way the LNBFs are wired. In your case I believe you are using a 22kHz switch, so instead of diseqc you would set "Tone" to on or off.

So for example I have
87W Ku using LNB2 (Ku)
87W C using LNB1 (C Linear)
47.5W C using LNB3 (C Circular)
34.5W C using LNB3
34.5W Ku using LNB2

each has a different Diseqc 1.2 number, and each position in the ASC-1 has its own count since the positions don't align because of the way the LNBFs are mounted

So you might need to download your ASC-1 config list, add all the Ku satellites as additional entries, and re-upload (it's a lot easier to do it on a computer than through the remote)

I hope this helps.

What E2 image are you using?
In OpenATV 6.3 all I see are:
C-Band
User Defined
KA-SAT
Circular LNB
Unicable / JESS
Universal LNB

That's where I hit a brick wall. I see this post that says it is supposed to be the right one for the US. :


Also I see in the photo it appears that the Ku mounted beside the C Band is rotated 90 degrees from what I'd consider the reference of the C Band LNBF's 0 skew reference. Am I wrong?

My GEOSATpro SL1PLL Review

Ok I got to see the FedEx man again today. I got a new SL1PLL LNBF and GeoSatPro 90cm Dish. Dish was great and had it together in a few minutes. So I used that dish of course to test the new LNBF. My favorite LNBF for a long time was the Chaparral Universal. I don't really need universal...

I'm using TNAP that came with the receiver, and also a few other images for playing around. As far as I know, only TNAP includes a predefined LNB type for the North American standard LNB, since E2 is more Euro-centric and they don't usually have that type of LNB there.

I think in your case you should use "User Defined", set both LO to 10750, threshold at 11700

the Circular LNB in that list might be a type used for Russian satellites in Ku, i'm not sure. In any case from a receiver perspective, it does not matter if a signal is circular or linear, other than maybe suing the appropriate labels for the polarity of transponders

Just as a favor could you possibly switch your settings to your suggestions and see if you get a lock?
Can you clarify something too that may help me at least get a signal?
Without current skew angle considered is your C lnb 0 reference aligned with the Ku 0 reference?
Because the photo sure makes it look like it may be 90 degrees different.

In its simplest form for the time being I'm just using my 2nd cable in the house to power the Ku.
Later on I'll insert either a DISEqC or a 22KHz switch in the mix behind the ASC-1. The goal is to just get a Ku signal on the lowest arc sat with the strongest signal. So far no joy.
I've even managed to run the USB com port adapter through my router that I use to program the ASC-1 through Ethernet to my laptop. Slick!

Using a straight cable without switches is a good idea, that's one less thing to worry about. I think I read earlier that you are trying to get 125W Ku. That's a rather difficult one. While it's definitely possible to receive it well, it's also a rather touchy one, a bit like either you lock on it, or you go in circle for a while in the dark, especially from our area in the NorthEast.

Instead, try CGTN on 95W, that's probably the easiest target in Ku. Other fairly easy ones: NHK on 103W and KBS on 123W (might be easy to aim for that one and still be able to reach the LNBF from a step ladder). Once you get satisfactory reception on those, look for 125W.

As far as skew, while i'm not familiar with the SL1-PLL, I would guess that the F connector should be pointing toward the ground when the dish is aiming at the top of the arc, parallel to the polar axis of the mount. and the LNBF should be aligned with the C-Band one in the plane that is perpendicular to the polar axis. Have the front of the LNBF more or less aligned with the front of the C-Band LNBF. Keep in mind that the reflector acts as a mirror, so if your Ku LNBF is East of the C-Band, your aim will be West of the C-Band, so for a given sat, for Ku aim further East to compensate for that difference. On mine, the difference is somewhere near 8 degrees. So for 95W Ku, aim your positionner either to 103W or 87W, do a blind scan, move a bit east or west, scan again, etc. In the end you should find something. Fine tune it as mush as you can

One more thing. Your dish mount alignment was tuned with C-Band. Ku is a lot less forgiving. So you might find that the alignment that was working well for C-Band might not work so well for Ku. You might need to compromise a bit somewhere.

arlo,

I went out a short time ago between rain showers and took this picture.
As you can see the Ku LNBF is behind the the C Band feedhorn.
I'm sure fine tuning the F/D will improve the signal, but for now and because of the rainy weather, it will suffice.
Hope this helped.

That's the photo I was waiting for.
I'll put one up later of mine.
I aimed the dish at 123W C band and holy smokes couldn't get a signal. +5, +10, +15....back and forth.
Put it back on 123W C band and did a blind scan. Got enough of a "strange" list of TPs that didn't make sense.
Slapped on my Dreamlink FTA receiver (they ID sat names) and I was picking up a signal from 110W. A DN sat.
That's 80 counts difference on my ASC-1. Got my head screwed on straight and grabbed a bunch of sats.

My Ku lnbf body (not plastic rain cover) is appx. 3/8 back from the C band lnbf throat opening.
Explains why I am getting a fat beam width. Takes about +/- 10 bumps of ASC-1 counts to get or lose signal.
Tweaks come later on. I'm guessing you've peaked your signal and that tells me I need to pull my feed back a bit.
Right now signal strength is in the 16-18 dB. Better than C band actually.

The only "bug" was putting in a 22KHz 1x2 switch on the back of the ASC-1 to use both LNBF's.
No joy with receiver settings. Put on a 1x8 DISEqC 1.1switch and got both feeds working.
Perhaps a bug in OpenATV.
