Help - G10R comparison

[Woofle]

Hi,

I'm wondering what size dish people are using to get 11720 on G10R.

I have reason to believe my 90cm dish is under-performing and possibly slightly warped. But everything works. It just can't pull in this transponder, which is extremely marginal.

It's right on the threshold of both my Mercury II and Visionsat IV-200 receivers, judging by how it repeatedly "bounces" between 0 and a signal level no matter how carefully I point the dish or skew the LNB.

I'm at 122.5 West, so G10R at 123 is almost exactly due south. To my simple-minded way of thinking, this makes it the closest satellite with the shortest signal path. But perhaps 11720 is pointed somewhere I'm on the edge of?

Anyways, if you get 11720 on G10R with good quality, let's hear what's your minimum hardware that does the job for you.

Thanks for any kloos. I'm short on Kloos.

check to be sure you are set on V, then check skew. I did have trouble with skew on this Sat. Using 75 CM primestar, excellent SQ.

 

[Woofle]

Thanks

Definitely had the correct polarization. I'll play with the skew, but I tried that a few weeks back and recall that it was already either peaked or pretty close.

I'm starting to suspect that when the dish fell, it may have slightly deformed. In that case I guess it's garbage?

 

[Anole]

Not necessarily. If you don't -see- any deformation, it may still have some.
The way to determine that is to take the dish down, and lay it flat on a table or floor.
If it touches all the way around, then it's likely okay.

There was a thread a while back, where one of our sponsors described how to restore a slightly tweaked dish to normal shape.
I'll look for it and post the link... unless someone else beats me to it.

edit: here ya go.

I'm using a 31" dish on a motor and I have great signal and quality on that transponder. S: 60 Q: 50-60.

 

[empiretc]

when i first got it setup, i scanned in 51 tv channels. now i scan in 48. best quality i have gotten on a strong transponder is 75%, 11720 comes in not so strong. in the words of Iceberg:

G10 rough ball
11800 V 26660
it's a thunder stick!

G10 11720 V 27692
for fine tuning. <---- that is the deal !!

10' mesh sami dish with corotor II feedhorn, cheapo eagle aspen .6ku lnb,
pansat 9200HD

11720V 80% quality
11800V 87-89% quality

I see some bendage on the rear of the dish on the outside edge upon closer inspection. Ack! But I'm looking at this from a glass half-full sort of way.

If that technique you posted fixes or improves the dish, I'm only out a little time. If it doesn't, I'll get another dish for my motorized setup and demote this one to dedicated service on G25, which it handles fine even as it is now.

Having the dedicated dish will save some wear and tear on the motor, since mostly it's G10R->G25->G10R->G25..... about 80% of the time. So even if it's "garbage", it seems to work well enough. Besides, I have 2.0 switches sitting idle and it would be fun to put them to use.

Or I could vent my frustration on it with a sledgehammer. Time will tell.

Assuming the "footprint" of 11720 V isn't a lot stronger where you are, and that I found some mild warpage on the rear of the dish, I'm going to take your success with a 31" dish as evidence my setup is broken.

Thanks for the data point and help.

If I had a broken dish that would get G25, I would leave it there and get a second dish and motorize it. Then probably a third for G10R. And then a fourth for... and fifth for.... :

Oh, yeah, that is what I am doing! But I have a lot of room. I had to put the Primestar 1M to get G25 well. The tin dish warps in almost every wind, but it works ok (only loses 3 channels) on AMC4.

has nothing to do with the footprint. Dish has a transponder at 11724 V next door at 121 so a larger dish will help block that out. Smaller dishes you can have bleedover when one satellite is stronger than the one next door. 11800 doesn't have that issue as Dish 121 has a 11800 (or close to it) but opposite polarity (H)

I never think of this.

This is a great answer ! - :up
I'm sure there are a few more such examples.
But just as with which bird has the odd skew, these need to be posted somewhere for the neophyte.
Maybe an addition for TheList? Or for a sticky FAQ...?

 

[Mr Tony]

but what doesn't make sence is this

-11724 V isn't lit up on 121 right now and hasnt been for a couple months
-11720 V on G10 was at one time recently back up to around the same as 11800

 

[Mr Tony]

nah. Its crosspole. We had a thread a while back on it. The bigger the dish, the less adjacent satellite rejection you get

On my 30" dish 11800 is at 90 and 11720 hovers around 50
On my 36" dish (well 37x27) 11800 is still at 90 but 11720 jumps to 60-65. Same receiver

Couple years ago there was a sports team that had the exact same issue with their feed. They were on a bad frequency on G3 and IA6 (at the time next door had a frequency that was like 4 off and same polarity so we had issues with the 30" dishes and that feed. The 36" dishes worked fine

Boy your quick.... after entering my post I knew it wasn't correct so I deleted it... it must of been there only 1 or 2 minutes at most.

Ah. I had not thought of that. I'm glad I went with 90cm instead of smaller for that reason too. Though a 1.2 meter dish is starting to look attractive.... where does it all end?

Just arrived is a GeosatPro 90cm dish. I plan to mount it on the motor and "steal" the fixed mount to do G25 with the old somewhat-bend fortec. News at 11 or something. Probably in the form of a review.

 

[eddybear]

Using winegard 1 meter+ (about 42 inches), motorized so I don't worry about skew any more.

I just got my 90cm dish up yesterday pointing to G10R. I am at 121.7w.
Mercury II receiver.
11720 55 -60
11799 65 - 70
