What am I Receiving?

Well the inverted dish will be pointing up at a greater angle. Deyond that my brain is not in dish mode. We are setting up for the kiddies tonight. Usual is about 80 -100. The forecast is 18c with mucho rain.
We're ready for the kids. In the last 3 years, we've had maybe 2 kids the first year only. Every year, I get to eat the chocolate bars after-the-fact. No reason to think this year will be different.
 
Inverted Off-Set

Take off Angle = 90 – (prime focus + offset)

Where 90 = vertical plane of reflector
Prime focus = calculated elevation based off of lat and lon of earth station and station
Offset = manufactures off-set of the boom/feed assembly to reflector surface
===============
Therefore for AMC 21 @ 11 degrees elevation:
Take off Angle = 90 - (11 +22) = 57 degrees

0 degrees: horizontal; 90 degrees: vertical

Note: When you invert the dish, you do not need to change the skew. I know because I did and had to change it back!

Here's what it looks like:

Good job. Is it working as well as you expected?
 
I'm aware of that. This is why I tried hard this week to receive PBS tps. I am receiving AMC 21 very well: stable SQ 70% from Claro which uses DVB-S2 also. There is something different about the PBS tps. I will conclude that using only the actual signal power at a particular receive location is not enough to determine if you will or won't receive a tp. I have never seen tps that supposedly could be received with an 80 cm dish that were so difficult for me to receive. For example, 123W supposedly needs a 100 cm dish. I was able to find 123W quite easily and all tps blind scanned in with reasonable SQ.

Earlier, I thought I had an LOS problem. I don't think so. If LOS was an issue, I would never receive Claro at 70%. I might receive it, but SQ would be down or unstable. I could see as I panned my dish slowly east/west and up/down that I am dead centre on Claro. I then checked and I could tell by carefully watching how PBS affects the SL and SQ bobble head that I was also centred on the PBS tps.

Inverting the dish was a good idea since it allowed full freedom to pan the dish up and down to be sure I was centred elevation-wise. By the way, this autumn season seems to be the best time of year to search for new satellites. I think it's the dry air here when the weather is sunny that is delivering maximum SQ on all satellites.

Sure have! I tried 3 different LNBs including my best PLL LNB. All gave the same results. You'll be happy to know I left the standard SL2 LNB in place since my PLL model belongs on my motorized dish and the Multistar universal performs very well except scans in frequencies 3 MHz high.

I'm going to drop this thread and start a more general thread with some questions that have come to mind as a result of this week's work.
 
One thing for sure, the various TPs are all at different power levels, there is no consistency. The Montana PBS I do not get at all, a ZERO Q.
 
And that indicates to me that published footprints, at best, are vague generalizations that especially at contour boundaries probably can't be trusted. Follow this thread further here.

Montana is easy to get here, but I lose SD06 on wet rainy mornings before I lose Montana with the way my 1M dish is tweaked. Would think the only solution is a bigger dish, the guy from Montana PBS insisting 1.8M is the minimum recommended size.
 
Too bad you don't have a USB / PCI Sat tuner. That would show you what's going on.
I like that idea since I do feel I'm working blind. A USB sat tuner would be easy since you can see I use a laptop at the dish anyway when orienting. But...that means spending more $. Won't happen in the short term.

That's to be expected. On rainy days (like today!) even Claro has disappeared from SQ 70% to bobble head. I've been hit on the head so many times with the knowledge I should upgrade to a 1.2m dish. I tell anybody in these parts they should use a 1.2m from Day 1 and learn from my experience.
 
Now have my Star Choice 40" x 44" in place just to see if this slightly larger dish will give different results. Now receiving 11944 V 1481, 12018 H 5000, 11833 H 2893 (SCOPUS-NET-TECH). Can anybody confirm if these are on 123W or 125W? I think they are 123W, but I'm receiving them while centred on the Claro tp on 125W.
 
Not sitting in front of my receiver, but I have definitely feel like I've seen "SCOPUS-NET-TECH" on 123 before.

Yeah those 3 tps are booming on 123W. This lil bigger dish is nicer, but still no PBS. Getting usual Claro well on 11980.
