Hi guys,

I am trying to split my satellite signal 3 ways. One for the sky stb and one each for the 2 dvb-s tuners on my Blackgold 6in1 card (htpc).

I bought one of DSE's 3-way splitters but this only has power passthrough on one output. I plugged the power pass into the stb and the other two into my blackgold card. The stb worked fine and the blackgold found all freeview channels. Problem was however that the tv tuner card had a signal problem (similar to sky's rainfade, blocky pic, warped sound, ghosting) which I couldnt shake. It wasnt constant, just every 20 seconds or so it would do it for a while. Not really watchable though. I tried changing the power to go through the card instead of the stb but then the stb wouldnt work...

So.... I ordered a 3way splitter that has power pass through through all 3 outputs. Plugged one into the stb, the 2nd into the tuner card but when I plug the 3rd one into the tv card, the stb stops working....

Im confused as Im a noob at satellite stuff. Am I missing something obvious here? Any suggestions?

Both stb or the tuner card work perfectly if I plug the satellite cable dirtectly in (with no splitter) so Im sure it's a splitter issue, but what?

Cheers

with the single power pass, plug your sky into it, use the two passive ones for the cards. Make sure you turn the LNB power off for all but the Sky box

What sort of cable are you running, how have you attached your connectors to the cable, and what sort of signal strength do you have on say the set top box when running only into that direct without splitter. Also, how long are your cable runs to the splitter and then out to the devices?

I had it setup like this the first time but got the "rainfade" problem on the htpc. Sorry but how do I turn off the lnb power for all but the sky box?

The tv card I have has a small internal power connector to the PSU which is for something like that. Is that involved? (sorry, noob alert!)

Im using the standard sat cable the sky guy installed running into a 3-way splitter then off that I have 3x 1.5m F-connector sat cables going to the different 3 locations. Signal strength and quality are good when cable is plgged into stb alone

Sorry if thats no help...

I don't know if this will help at all, but this is what I found with my BGT3540...

I am running satellite within Vista MC including the TV Pack 2008, using a 2-way splitter from DSE...

- When doing the scan, only the top satellite input worked
- When attempting to watch the TV after doing the scan, the top satellite would not work, so I had to change to the secondary satellite input, and that worked.
- When I used a splitter, I found TV would only work providing I inputted the signal from the split cable that had the power pass, into the secondary satellite input on the card.

So the conclusion I came to, was that the top satellite input/tuner #1 does the tuning, but the secondary satellite input/tuner #2 displays the TV, and requires the power pass through.
(bearing in mind this is only what I found within Vista MC...I can't remember which tuner was used when I had GB-PVR running)
