What signals can you "see" at 61.5?

625 in northern VA. I am now reading "spotbeam" on all odd transponders from 1 to 15. Transponder 3 seems normal. Transponder 13 signal strength went down to 75, but still shows anomalous ID behavior as above.
 
I swung the 90cm over to 61.5 just to see if I could catch a little more than the 18 inch pointed there. Sure enough TP 9 locks in with 54% strength on the Genpix. It's completely void of any tables though. Without any tables yet I don't what signal this is, maybe a test signal from the Jackson, MS uplink since that is the beam I'm under.

I was looking on my 722. I'll check the 625 tonight.

Can you explain how I can lock onto 8 spotbeam transponders from northern VA? I thought I was only going to get 2. I suppose that, if everybody gets 2 spotbeams, then I'm seeing my own plus 3 adjacent DMAs.

Guessing here: the spotbeams actually overlap quite a lot, and different transponders are used in adjacent DMAs so as not to interfere with each other. But DMAs farther away, such as your transponder 9, must carry a completely different set of channels than my transponder 9, even though they're transmitting on the same frequencies.

You're thinking of one spotbeam equals one transponder frequency. That is not true. One spotbeam has multiple frequencies(transponders). Think of it this way. Using the flashlight theory you of course have one finely tuned flashlight shining on the globe in you area. Instead of just one color(frequency) coming down multiple colors(frequencies) are sent down to the same area from the same flashlight.

Interesting you're getting 8 spotbeam transponders though.

Actually I wasn't thinking that way, but I see that I mis-typed, making it look as though I did. I should have said "if everybody gets 2 spotbeam transponders..." Anyhow, I apologise in advance to anybody who gets offended by my professorial know-it-all attitude evidenced below.

I have pondered this problem some more. For the mathematically inclined, the solution is contained in the 4-color map theorem, which states that you can paint any 2-D map using only 4 colors, without coloring any two adjacent countries the same. Just substitute transponders for colors, and spotbeams for countries, and you have the result I am seeing.

Notice that spotbeams overlap somewhat, just like countries butt up against one another. To prevent the same transponder frequencies from interfering with each other in adjacent/overlapping spotbeams, transponders in adjacent DMAs must be different. Non-adjacent spotbeams can reuse the same frequencies. If each DMA needs 2 transponders to carry all it's local channels, then 2X4 transponder "colors" equals 8 transponders, exactly the number I can lock. ;)

I furthermore make this prediction based on the proof of the 4-color map theorem. If anybody can lock more than 8 spotbeam transponders, then Dish is wasting bandwidth. :D I have gained a new respect for Dish's engineers. They're pretty damn smart.
 
Echostar 10 has adjacent spotbeams with the same transponders overlapping.....but they don't overlap in the DMA though so it will only affect the "movers".

Looking at the ability of E12, it looks like 2 areas could lock onto 8 spotbeamed transponders. That's if they use the full ability of the bird.
 
My strongest signals come from Beam#4 (TP5,9,11,13). I get weaker signals from Beam#5(TP1,3,7,15). The conus TPs from E3 are somewhere inbetween :).

TP1 has Richmond, VA locals. (Beam 5)
TP3 has Raleigh, Durham, NC locals. (Beam 5)
TP5 has Washington DC locals. (Beam 4)
TP7 has Greenville, NC locals. (Beam 5)
TP9 has no channels (possible Baltimore, MD? Beam 4).
TP11 has Philadelphia, PA locals (Beam 4)
TP13 has no channels (possible Norfolk, VA? Beam 4)
TP15 has no channels (possible greensboro, NC? Beam 5).

Should we form a mobile satellite signal finder group and drive around to find where the edges of the beams are? :)
 
I was looking on my 722. I'll check the 625 tonight.

I checked both the 625 and 722 at 7:50PM EDT tonight. The 625 still identifies TP 3 as Spotbeam, but the 722 does not. The 722 does correctly identify Sat 110, TP 29 as a Spotbeam.

Sorry, the 722 is running L4.49 and the 625 is running L4.64.

Slightly off-topic, but my 625 now says software version L463, and it shows Previous Software as L464. Was there a problem with L464 that would explain the downgrade?

Thanks,
Ted

L463 went out to all receivers last Thursday night and you're right the previous version was L464 so they must've downgraded all receivers.

Check your TP numbers below 20... mainly the odds, folks. More beams are coming online tonight.

I moved the 90cm over to 61.5 and I can lock 3 spotbeamed TP's. 2 are really low and I can't not get any info from them. TP 9 has the Beaumont HD locals on them though. 3 out of 4 are there, KBTV is only around 2 megabits. Barely sneaking this TP by on the signal meter. I'm really surprised I can get this beam when I'm on the western portion of the beam for Jackson, MS/New Orleans, LA area. Guess that proves the Jackson, MS site isn't online yet.

Can someone in Southeast TX check 61.5 transponder 9?
 
Looks like TP 13 is also up with 5 video streams. I can't get a positive identification due to the very low signal here but this has to be Houston, TX HD LiL.

TP 11 is also going with 4 video streams. I don't see anything listed for TID 1311 so maybe another market tomorrow? Hmm..what other market is in SE TX on the list?

TP 05 is alive with 4 video streams. Austin, TX LiL.
 

Anyone get better than low 30's signal on 61.5

I lost two HD channels in Puerto Rico
