Classic Arts Showcase - IA6 @ 93W

[blacktop]

First off, thanks to Larry1 & Iceberg for enlightening me on using a stacked linear lnb (E75 dish) with an FTA receiver....

I think everything is working okay now for IA6 & IA5, but I have one question about Transponder 6 on IA6 - I see that both Lyngsat and Global-cm have the frequency as 11836H and a symbol rate of 7179. When I try to convert this H transponder to V, I get no signal strength showing.

Is that because this transponder is not always lit up.? When I go to the Classic Arts Showcase website they don't even mention the IA6 satellite, just the G15-TR5 NTSC signal. They mention that "We're available 24 hours a day, free and unscrambled, from satellite Galaxy 15 Transponder 5" which would make me believe that IA6 would be similar. Can anyone enlighten me as to what's going on or what I'm doing wrong?

Here's what I tried to do ... works perfectly on IA5:
-LNB setting is "single" LOF 10750 (this is on a Coolsat 4000, all other transponders have a good signal)
-create a new transponder of 11836+575=12411 with a SR of 7179 and V polarized
-no quality shows up {??}
- the only thing that comes to mind is a bit of dish tweaking might be required, but every other transponder on IA5 & IA6 have good to very good signal levels.

thanks folks

Never cama across a stacked LNBF .

Where does the number 575 come from ?

Does your receiver do a blind scan ?

The dish I am using is a Channel Master E75 with California Amplifier Stacked Linear's , set for 4 degree spacing. This dish was used by Star Choice for a while after they began broadcasting from their second satellite location @ 111 degrees.

They have since switched to a quad legacy.

The 575 is the difference in Vertical and Horizontal LOF's to create the 'stack'.

Coolsat 4000's do have blind scan and I have done that at several different times of the day in case their schedule changes, but so far no luck. I'm fairly new to this, and was wondering if I leave the lnb setting as 'single' with LO of 10750, if I really am going to find all available frequencies, given the 'stacked' nature of the lnb's.

{That was why I originally went to manually inserting the transponders and ran into the problem on the first post.}

I havent seen this up there in a LONG time...maybe 6 months

I know nothing about stacking. I'm confused as to why you would change a horizontal polarity to a vertical polarity or rather, I wonder how this could be done? Maybe that's what stacking is? If it can be done, I'm confused as to why it's necessary? Why can't it be left at horizontal? I might understand better if the 2 birds were next to each other with opposite/reversed polarity's. But, these 2 birds use the same polarity's, so I'm at a loss.

that's probably it ...

Thanks Iceberg, that's probably why I'm not getting anything. On Mike's site, his listing on the Mpeg2 page for Ku FTA dated March 16/06 still has it listed, but I was suspicious when I saw no reference on the CAS homepage. I was aware that Lyngsat's stuff can get a little stale-dated.

thanks again,

i am getting the arts channel on ia6 (1st time ever)


11841h 4000

Stacking is when a device lnb or otherwise will place either the V or H polarities above the others. For instance in the cable world there is HITs QuckTake. On G4R you can use a single dish with a single LNB to get both the H and V polarities at the same time. It takes the H polarities and places them in the norman 950 to 1450 MHz range. Then it places the V polarities above them in the 1450 to 2150 MHZ range on the same wire. This allows 1 LNB to get both the V and H polarities at the same time on a single wire. The thing to remember is that you are using the whole L-Band spectrum (950 to 2150 MHz) and the higher the frequency the more the attenuation in signal.

I hope someone can make some sense of what I am trying to say here,

and the one advantage of a stacked system is you can run 2 receivers off a single output with a high frequency splitter (the older StarChoice setups were like this)

Thanks Wholeshoe and Tony, now I have some knowledge of what stacking is about. Maybe someday I'll get to experience it, to get a better understanding.

Great point Iceberg. There is no DiSEq switchs to fool with if your interested in a single satellite with multiple receivers. You can get individual devices that will stack two lnbs. I don't think they cost a bundle either.

The only reason I know this is on the Canadian TV board there are people with just a single dish with the GIANT "flashlight" LNB with one output and they are running 2 recievers with a splitter on it

Would like to get my hand on one of them but they are larger than the normal 40mm holder...I think its a 50 or a 60mm

Dish Network's DishPro LNBFs are also stacked LNBFs. Stacking is a novel and, in theory, useful practice, but as Wholeshoe pointed out, you are using frequencies up in the 2ghz range. If you don't have PERFECT, high-quality (2.25ghz rated) cable and every device in your system doesn't pass frequencies greater than 1.4 ghz (which is a limit for some hardware), there can be frequency attenuation problems.

And then there's the problem of converting all of your transponder frequencies
