Satellite guys Exclusive! Mad Scientist! 129 ON BOTH SUPERDISHES!

[rocatman]

If one can get 105, 110, 119 and 129 on a Superdish, there shouldn't be any reason one couldn't get 61.5, 77 and 85 on a Superdish.

different animals

77 & 85 will be lower powered, due to the proximity of 82 so it will be tough

105 is the only low powered one in your example above

sorry to say that the spacing is too far if you wanted to go with 105 and 61.5 on the same dish

as far as getting 61.5 77 and 85 on one dish you could do that but you would need a 2nd dish to go with the 105-121 slots..

 

[KE4EST]

With all these sats now, surely dish is also working on a DPP54 or DPP64 switch.

edited title to reflect the 105 and 121 dish successes.

I tried this tonight with my 105 SuperDish and was surprised to get a 75 signal just by holding my LNB about an inch to the right of the 119 LNB pointed to the center of the dish.

I BELIEVE that this is 129. I was using a FTA receiver outside with the frequencies programmed in. Until I can get the LNB tied down I can't be 100% sure but I am fairly certain that it is.

But that was all I was able to do as we were hit by a major storm which kicked down a few trees and branches.

Next step is to try it on the Dish 1000. (But first I got to clean up some things around the yard from the storm) (They really need to make weekends longer)

 

[Scott Greczkowski]

I got it!

I hooked up a free to air receiver of it and found a bunch of locals from 61.5 and 148 in the listings however none were tuneable (not even 9001)

John H said at DBSTalk he is seeing some possible HD activity up there as well.

On my 942 I am seeing the satellite but am not seeing anything off of it yet.

This was a fun project.

 

[Smith P.]

Scott, could you please post a list of locked transponders for HD receiver and FTA one ?

 

[Scott Greczkowski]

THE FTA one is no longer hooked up, but here is what i used.

12253R 20000
12282R 20000
12311R 20000
12428R 20000
12457R 20000
12515R 20000
12268L 20000
12414L 20000
12443L 20000
12472L 20000
12501L 20000

Now on the 942 through the point dish screen here are the transponders for which I can tune to currently

15
16
17

No other transponders are available yet on the 942.

 

[Smith P.]

Thanks, same as I reported at DBSTalk before; my thoughts was if 942 could find more 8PSK transponders then my 8PSK card.
We will check them when NIT will populate.

[JIGGIEFLY]

I have a superdish on 110/119/121 & 61.5 on a dish 500 i see a lot of 105 installs that are working, were is a good start for a 121 superdish.
I also have a spare voom dish and a spare directv dish also whats the best lnb to use for the superdish or is it better to get one of my spare dishs setup and what lnb is the best for one of those dishs

everything but HD is qpsk, hd is 8psk

PSK are not usually assigned to a HD or SD channel. HD over the air is 8VSB. read the difference between Q & 8:

8PSK (8 Phase Shift Keying) is a phase modulation algorithm.

Phase modulation is a version of frequency modulation where the phase of the carrier wave is modulated to encode bits of digital information in each phase change.

The "PSK" in 8PSK refers to the use of Phased Shift Keying. Phased Shift Keying is a form of phase modulation which is accomplished by the use of a discrete number of states. 8PSK refers to PSK with 8 sates. With half that number of states, you will have QPSK. With twice the number of states as 8PSK, you will have 16PSK.

Because QPSK has 8 possible states 8PSK is able to encode three bits per symbol.

8PSK is less tolerant of link degradation than QPSK, but provides more data capacity.


QPSK (Quadrature Phase Shift Keying) is a phase modulation algorithm.

Phase modulation is a version of frequency modulation where the phase of the carrier wave is modulated to encode bits of digital information in each phase change.

The "PSK" in QPSK refers to the use of Phased Shift Keying. Phased Shift Keying is a form of phase modulation which is accomplished by the use of a discrete number of states. QPSK refers to PSK with 4 states. With half that number of states, you will have BPSK (Binary Phased Shift Keying). With twice the number of states as QPSK, you will have 8PSK.

The "Quad" in QPSK refers to four phases in which a carrier is sent in QPSK: 45, 135, 225, and 315 degrees.
QPSK Encoding

Because QPSK has 4 possible states, QPSK is able to encode two bits per symbol.

Phase Data
45 degrees Binary 00
135 degrees Binary 01
225 degrees Binary 11
315 degrees Binary 10

QPSK is more tolerant of link degradation than 8PSK, but does not provide as much data capacity.

 

[BFG]

You really didn't have to type all that

I know what is what and that sd and hd aren't restricted to either.

I was simply explaining that on Dish Network they are only using 8PSK for their HD and QPSK for their SD

 

[Smith P.]

Nay, they use QPSK for demo HD channel and before implementing 8PSK used too - just try to find when that 8PSK module came to 6000 and how many HD channels been before that.

 

[cablewithaview]

I didn't type it all. I had something bookmarked from a while back. I did however like the 8PSK Voom was using on all of it.

 

[BobaBird]

P. Smith, the 6000 got the software for the 8PSK module 6-12-02. Discovery HD moved to ch 9420/8PSK 7-1-02. The other QPSK HD channels were Showtime, HBO, and HD PPV.

 

[Smith P.]

Thanks BB, you made best correction to BFG's speedy answer. That's how Dish Encyclopedia should be written .

 

[James Long]

Thanks BB, you made best correction to BFG's speedy answer.

At this point in time, BFG's speedy answer is correct. Let bygones be bygones. Does it matter that some HD was once available in QPSK (and a certain now obsolete receiver was advertised as the only HD receiver one would ever need)?

In today's world, August 7th 2005, dish is using 8PSK only for HD and SD is only on QPSK carriers. Tomorrow that may change. Tune in to the tech chat Monday night and see what they have to say.

JL

 

[BobaBird]

I didn't realize I was correcting anybody or that a correction was even needed. BFG is correct about current usage. You are correct that Dish HD used to be at QPSK. BFG had already said he knows that SD or HD can be either QPSK or 8PSK but didn't feel a need to go into the history. In the end, all we've gained is an interesting (or maybe not) bit of trivia.

 

[Mr Tony]

got it on a Dish500 m (Legacy too)

Only a 75 signal on TP15 (my only options are 15,16,17) but it worked.....only issue is right now it looks like it acknowledges Legacy (because with the SW21 up, I can tune the TP on the screen), but it shows "X" in the spot
