I did the maps with the colors based on normal dish installations. Nothing is really normal in AK and HI, eh?
I would have been a ton more work to convert the dBw values to dish sizes then include the labels on every single map I had to make for all the spotbeams (which took a lot of work in the first place). I tried to make it very easy for the average joe with a typical dish installation to see how he/she would do in the spotbeam coverage.I'll take a shot at this one though... not all maps are this color key, but for this one. Red = 46dBw, Yellow = 50dBw, Green = 52dBw. 36dBw is not shown, but if you draw another circle around the outside of the Red one about the same distance and shape, you'll have the 36dBw.
This is why I see footprints (EIRP) just as a reference. I know satellite builders provide them based upon power, TX antenna, shape, atmosphere, etc.
I had a discution with other members in other boards that they (footprint projectors) don't actually go arround the CONUS and read (messure) they can't send a vessell each time they launch a bird, all you can do is predict based upon certan factors.
This I know due to the fact I'm in Fringe area and I receive all the satellites that several web pages that give satellites footprint show my location doesn't even appear in any contour.......but I get it!!!
As an expert in Fringe reception I must add to this toppic that I personally have suffered signal fade in the range of 3 p.m. to 6 p.m. The phenomenon I have researched to anlyze this specific variable and I have concluded that in that range of time, angle of the earth in that lapse of year, that was the window of time that the heat of the sun reached peak levels, so that it accelerated the particules of the atmosphere and attenuated my reception....this happened with a 3.8 m antenna had to upgrade to 5.0 m antenna and in the same range of time it attenuated but as the gain was so massive it compensated levels so I still was able to receive.
Other factor I have suffered in the past is as I posted previoulsy; twice since 1998 to 2009 I have suffed loss of signal from birds at 119W (old EIV, now EVII) because the operator didn't maintain the exact stationkeep; so target was slightly strayed and only people in fringe will notice. In these lapse of failure I lost sinal from 12 a.m. to 6 a.m. (nothing to do with the heat in the atmosphere) and then in the second failure as posted above. Failures where periodic similar to the figure eight movement of GEO satellites.
They don't maintain station keep to the degree needed for deep fringe folks, just enough for the everyday standard installation. There's no gas station at geo to refuel
Dish monitors several sites across the footprint of the satellite watching for signal issues. I've seen photos of the pages before. If I remember correctly they had a national radar map on top of the sites with the respective signal numbers to watch for satellite anomalies.
You'd also be surprised just how accurate those maps are of the footprints of CONUS and spotbeams. E10 and Ciel-2 really impressed me.

I know you can not tell the future but if they do end up with a tighter focused beam on the sat they plan for 119w would it be foolish to think a 6 foot dish would work? Reason I ask is the yellow line seems to almost as far north as the current sat.
As to what I said about spot 3 and 5 was a mistype, I know the actual spotbeam # is diffrent from the tp number when I am checking the signal strength.
Also those maps to me seem a little off, for example the 110w map shows the yellow line alot closer to me, but I can not get the spotbeam for 01 which is tp 12. I get zero signal even on the 1M dish.

My miami channels have gone???
The channels are still there but the signal is not. I lost the lock on saturday a bad weather day here in jax. I thought it was the rain. But when the rain went away the signal never came back. I reallined the dish and all I managed to do was increase the signal on the caralina spotbeams.
Any one knows if dish tightend the focus on the spotbeams? I checked the uplink reports and did not see any changes to miami.
Any insight would be appreciated!

What Sat?
Which sat were you receiving them on? The subscription list shows them on 110 and you are barely in the spotbeam for a small dish (standard 18") you might have to go to a largere dish to get it if they have either tighten the beam or reduced the power.

You probably won't hear anything as they don't release things like that. As long as they keep the DMA lit up then they are good to go. It seems I hear from fringe folks about losing signal every winter season (not due to dish obstructions either).
Well I am using a 1M dish aimed at 119 the SD locals are there.
That's what I thought.
well the miami spotbeams are back and with a strong signal IMO of 55 on my 3900. They came back 5 days ago on the 17th. I have had a lock all day and night since.
So for 2009 2010 the signal loss was from 11/07/09 to 2/17/10.
