If things go as planned, Directv 15 will launch 5/27 late afternoon Eastern Time (probably around 5:15).
The downlink band for RDBS(Reverse band) is basically the same as the conventional DBS(KU) uplink band to within around 100 MHz for service in the U.S, so in way reversed, directv tested this with D12 as you would assume if uplink and downlink is sent on the same frequency interference would be a problem, but turns out interference is only immediately around the DBS uplink facilities and is fairly small.What are Reverse Band Transponders in the DIRECTV 15 satellite?
Thanks for the info.The downlink band for RDBS(Reverse band) is basically the same as the conventional DBS(KU) uplink band to within around 100 MHz for service in the U.S, so in way reversed, directv tested this with D12 as you would assume if uplink and downlink is sent on the same frequency interference would be a problem, but turns out interference is only immediately around the DBS uplink facilities and is fairly small.
Also people forget directv's Ka-lo sats(D10 103CB, D11 99CB) or B band sats use a frequency that was originally for the uplink band for 2 way satellite internet service that hughes had planned using on the Spaceway 1/2 sats. Ka-hi for download, and Ka-lo for upload on 99 and 103. Directv just took that bandwidth and flipped it around to have twice the one way bandwith for downlink.
Glad to hear it is up with no known issues. D15 will carry the future, more HD and will pave the way into UHD for those bleeding edge types.
DirecTV was kind of in a holding pattern until D15 is successfully operational. I have no idea if it is related to the issues they experienced with D12 a while ago or if it is planned redundancy so to speak, but it seems part of their plan.Do you know what D14 is going to be used for? I thought it would bring a lot more HD channels but it didn't.
D14 is providing many popular channels that are also mirrored to Puerto Rico, as its capable of US and puerto rico broadcasting simultaneously. So directv has been removing channels off the old sats and on to D14 that they also want to send to PR. D15 can do the same thing, while it won't add much bandwidth to the US it will add a lot for the PR market. Directv has a ton a free space now, they are just moving things around to use it most efficiently, for every channel they move to D14 and soon D15 will equally free space on D11 and D12 for new less popular HD channels the don't want to send to PR.Do you know what D14 is going to be used for? I thought it would bring a lot more HD channels but it didn't.

I wonder if it has the Premier coverage where if an LCD screen breaks at the uplink it's covered by the protection plan! Haha!
