Polarization on 77° W

[WilburSmith]

Hello,

I got a question I've been wondering about and research leaves me stumped.

I can see channels coming from 77° W. However, according to tvrosat there are only 4 of them. But I'm blind scanning 10 of them ever since they started to transmitted 77° W. LyngSat doesn't even show these channels.

On top of that TVROSAT states that the polarization is 'L'. But as far as I understand my lnb only supports H & V. Some research lead me to believe that I need a special feedhorn to receive L or R polarized signals. But this doesn't appear to be the case in my situation.

So, what's going on exactly?

What channels do you think you see on 77° W? Please list the exact channel names and include their transponder Frequency, Polarization, and Symbol Rate.

There are two types of polarization used on satellites, one is call "Linear" polarization, the other called "Circular" polarization.

Linear is used on most FTA satellites like Galaxy 19 at 97W, there you have Horizontal and Vertical polarization's, it also used on most "C" band satellites.

Now Circular polarization (Right and Left) is used on the Dish, Dish Mexico and Bell satellites, you would need a different type of LNB to see that type of polarization, these satellites are encrypted and you should not see any channel programming.

As I mentioned above TVROSAT lists 4 channels for 77W. All 4 are FTA as well. They have a L polarization and I receive all four. My question is why? No, I'm not hacking!

LyngSat lists the DishMexico sats you were speaking about buy fails to mention the four on TVROSAT.

Nonetheless, I was curious why I receive L polarized signals.

What means "think you see" ? Thanks

Maybe because of your geographical position:
17838
probabilly the person who scanned/reported the channels on Lyng, doesn't has a geographical position to receive this tp.

Exactly what it means. What do you THINK you see???

Without providing any information about the channels or transponders you found, it is a mystery to everyone else. It is common to assume or think what satellite you are on. Information on TVROSAT, Lyngsat, or any other satellite listing site is not always accurate.

Can you define your definition of "What do you THINK you see". Thanks

Look, This has gone far enough.
If you don't want to answer simple questions, then don't ask simple questions. This is getting to the point of laziness or you will just provide whatever information you think is needed. Tons of information about polarities and how much signal you will lose between linear and circular signals is on the internet. In the future, if you want to ask questions on this forum, then be prepared to supply the information needed to answer them whether you think it is necessary or not.

Hi All!

I recently asked a question about L polarized channels I found on 77W.


I was stumped when asked by el bandido "What channels do you think you see on 77° W? " because I know what my eyeballs were seeing.

In a reply to Terryl I showed a screenshot of the information I found on tvrosat and it's these channels I'm able to scan. I'm just curious to know about why there listed as 'L' polarized.

elbandido closed my thread saying I was lazy and don't want to provide information but I don't agree with that comment because I did share a screenshot from tvrosat that shows what I'm talking about.

Somewhere along the line tempers flared up and I don't understand why?

What you scanned doesn't agree with either Lyngsat or tvrosat.Y.our channel count is wrong for tvrosat and is way short for Lyngsat..
Sometimes you have to provide information if you want information. If you don't want to do that, then don't ask questions.. People here are not going to ask you something for no reason...

Now, What exactly dd you scan? Provide the transponder information along with the channels that were found on the transponder. You can do this with a screenshot or write it. For transponder(s) provide the frequency, polarization and symbol rate. Don't provide information from Lyngsat or tvrosat. Show what your receiver found Simple enough.

[WilburSmith]

Of course my scan agrees with tvrosat. Tvro shows 4 channels and I get those four channels. No more no less. Even provided a screenshot!

I don't think I should even get the channels on Lyngsat as those are paid channels. I'm doing FTA. I just wanted to point out as an observation that the 4 channels I receive are not listed on Lyngsat.

I have provided information twice now and you always reject this point. Why?

Like I've stated repeatedly I scanned 77W and got the 4 satellites as shown in screenshot. I can't add more to that.

[el bandido]

I combined the two threads as they are the same. Re-Read the first post in this thread and you will see you had a different view then with 10 channels scanned, but now 4. Actually neither one is correct for what would be on that satellite. The tvrosat dude that does the charts is in Canada so he has no direct access to that satellite.


You can expect to lose at least 50 percent of the signal when receiving circular signals on a linear lnb. That answers your question so the matter is closed.
