Backup, more spot beams?
There's room now for some more HD channels, but not 96 channels. D14 will allow for D* to pretty much go full HD if they want to, and provide for 8K super HD.
Also going with the new standard 6 HD per transponder, with the new encoders.
D10 may be going to in-orbit spare. The Net gain could be 16 CONUS HD or less with some mix of SD. In combination with other satellites going to six channels, it could get interesting once again.
The Ka transponders are so wide, it seems like they shouldn't be sacrificing much.
Huh ? Did you read the FCC document ? Its' regular 36 MHz.
Great question RAD! Everyone seems to be avoiding the answer!
Pretty much know the answer. Why pay for/provide something that is going to cost you money, if the customers arent leaving because of the lack of its presence?
As long as new customers keep signing up, current customers keep staying, then I dont see them getting in any hurry to add those remaining 8 or 10 channels most of the other carriers have. Besides, they have the sports thing locked up.
I thought participants of the discussion are reading FCC doc, but seems to me it not happened.
It takes years to build, test, launch and enable a satellite. Directv has to plan 3-5 years out for these things. D14 has been in development for several years and won't even be in service to customers for another 2 years.
If Directv waits until they have a capacity problem it'll be too late to get a bird up and operational. With the age of the existing sats, the coming explosion of RSNs, potential new technologies, etc, etc, it makes perfect sense for D14 to be launched.
Regular is a relative measure.
Regular for the Ku band is 24MHz with 35 guard bands. 50% more is a lot even if you have to pump up the FEC. If you lose it all to FEC, then I understand why RDBS is so important for the somewhat distant future.
Have you seen docs for D10/D11/D12 ? D14 has the same Ka tpns. You should start here, not from Ku.
The important info is in the Schedule S!!
Can anyone post the schedule S or the link to the IBFS filing and I'll see if I can decifer it.
It's not in PDF format, otherwise would have posted as usual Will post a link when I get near a PC.

There usually are two reports to review.
One TXT/PDF and the other an MS Access file of gps co-ordinates of the "beams".
Only the Access file is available.
I'll need some help but try to see how complete the data is ie "All" of the spotbeams or just a few samples as they frequently do. The D-10 Data was the full 49 spots and the most complete data we have available.
I found in Exhibit B:
That may well explain why the "Beam Points" are not available in the file.
Data error messages come up trying to read the file. The individual GXT files have the beam points I believe.
I did see that there are 76 TPN's available in the 46 Spotbeams.
Spots are A01 to A22 and B01 to B24.
Most are 2 TPN's per beam (26) but two A06 and A08 have 3 TPN's and 18 including A21 & A22 as well as B21 thru B24 have only 1 TPN
Also 16 National TPN #9 thru 24.
These 16 are replicated twice, once in Hawaii Beam and again in the Puerto Rico Beam.
And don't forget the d15 is already being planned as well, right? In fact, is it two or three satelites in the pipeline?
I wonder how hesitant DIRECTV is aout adding too much more Hi Definition incase d10 completely fails, both local and national. And what will their plans be when they do get d14 up? Will they launch more lil which may be their biggest area of need for a new sat?
I believe 15 is supposed to launch at the end of 2014. They do need to get these up there in case 10 does fail. Since it's running on backup propulsion, they accelerated the schedule.
