Here is info to order "Sat C" components

[PrivateGuy™!]

Excellent post Scott! Keep the info rollin in.

I've also posted this on the hardware board.

Following is the information to order the necessary components to add the third satellite position to an RCA Oval / Eliptical dish.

Note: the LNB IS NOT a standard DTV/DishNet LNB, and apparently the "combiner IS NOT a standard multiswitch (tone/no tone)...I've been told it's acutally a diplexor or sorts.


Anyway....

RCA / Thompson spare parts / Accessories: (800) 338-0376. Menu options 1, then 3.

Tell the tech the associated system is part number "DSA 8900E"

You need 1 LNB, part Number 247795 (US$ 70.10)

AND

1 "combiner," Part Number 247798 (US$ 17.10)


They currently DO NOT have a "kit" part number.

No additional hardware (screws, bolts, etc) is provided.

Exedited shipping is $15.00 (FedEX)

To hook it up, remove one of the "B" sat inputs on the 4X4 MS and connect it to one of the inputs of the new "combiner", connect the lead from the "C" sat LNB to the other input of the combiner. Connect the output of the combiner to the ""B" sat input from the first step.

Remember to change the settings on the IRD to reflect a 3 satellite setup instead of the original two.

You can verify proper setup by looking at channel 90 (only available on the guide if you've selected the "3 satellite" setting in the setup menu). Channel 90 is the 'Third satellite confirmation channel"......


Hope this helps y'all, admins feel free to cut & paste into an FAQ list if you want.

I finally received the "Sat C combiner" (RCA part# 247798).

It looks like a regular line splitter, it does have specific labels for the "sat B in" and "sat C in" and "out to milti-sw 18V/22KHz" and apparently has DC passthrough on each port....this one has an "NAS" label on it, so perhaps they will start selling directly...or other NAS dealers can get 'em.

The NAS part number is "SSC-1"

...Yet another addendum.....

The connection to the multiswitch from the combiner must be to the 18V (LHCP) terminal of the "B" satellite input. You can do the signal strength check on transponder 10 & 12 of the 119/110 signal meter. Depending on the hardware you choose to mount the "C" sat LNB, you can get +/- 10 on the meter by wiggling/adjusting the LNB on the mount.

What is your signal strength for transponder 32 @ 119? Mine has 0 while the other 10 transponders have 80+?

Sorry my post looked disguised by you quote.

Smack....Great info. but are you certain a special LNB is required ? Have you gotten one & is it a single output LNB ? Also, have you noticed what the MHz range on the combiner is ? Sorry for all the questions but I have a couple dozen LNB's laying around
and many more combiners. I don't know if I'm willing to fork out 85+ bucks for **** I already have in my possesion. Any info. is greatly appreciated !

I tried standard LNBs, I tried standard splitters/diplexors/multi-switches. None worked.

The LNB I purchased from Thompson is labled as 'Sat C Only', and shows an IF of 950-970 Mhz (standard is 920-970). The only marking on the combiner is that it was produced by NAS, and specifically is marked for the 18V (LHCP) terminal of the "B" port of the 4X4 Multiswitch.

I imagine that if the combiner had sharp enough cutoff from each input, perhaps a standard LNB would work...if not then the additional bandwidth(s) may interfere with one another...since this is digital stuff, you either get it or you don't...there's no "snowy" picture or herringbone to tell you there's interference...

I s'pose you could start with purchasing the combiner ( ~17.00 US$) with a standard LNB, if it doesn't work, then buy the "special" LNB.

As far as I can tell, with a "plus" IRD, the only programming on the 110 bird is the test channel (I haven't looked in Engineering mode yet.

Thanks for the input...I believe it is the combiner that's neccessary to collect the signal. The 110 bird broadcasts the Raliegh/Durham locals and some High def. channels aswell.

The Special LNB has a shifted oscillator frequency which shifts the 3
transponders(28, 30, 32) that DirecTV owns at 110 to Transponder locations
8, 10 and 12. This way they can be diplexed with the 11 Transponders that
DirecTV has at 119 eliminating the need for a switch with more than 4
inputs. Since DirecTV only has 3 transponders at 110 there most likely will
be no other programming except the existing locals on 110

You know I get more consise and complete information here then I can get from the yahoos technical support staffs at any of the main manufatures. Has anyone tried ?
What a joke.
Anyways, thanks so much to smack & viper6 !
You guys have been very helpful. I hope I can return the favor sometime....
