Having problems finding sats - LNB questions

[cyoungso]

I have spent 3 days trying to get my new system running.

Twinhan 1022 card
30" offset dish
LNB: Gospell, input 11.7-12.75, LO 10.75

The only luck I have had is with Echostar 9 at 121. I was able to get the "correctly aligned" channel with background music.

I am rather baffled at what the LNB settings should be. Should they be different for each satellite? I want to watch Intel 5 and E7 for the NASA channel.

I was using the built in signal meter on the VisionDTV program but it alway read 75-80%. I switched to ProgFinder and was able to find 121.

Thanx

Echostar 7 is using circular polarization and you need a different lnbf to receive it. You should be able to get IA5, but patience is required

Signal Meter that comes with VisionDTV is not the greatest. It will not update correctly as you ar moving your dish. You need to selecect an active transponder and hope it either locks on it or refresh it every time you move the dish. Progfinder is little bit better as it will try to continuasly lock, but the kkey is that you have to move yur dish and then wait a while to see if it lock on it. So let's say you are looking for IA5, move the dish left right, wait 15-20 seconds and then move it again. Same gos if you are adusting the elevation.

That's why patience is number one requirement

What type of LNBF is required for E7? Whay was I able to see E9? Does it use the same system as IA5?

Also, what should my LNB setting be?

Thanx

For your lnbf, you should use 10.750 GHz, which you noted in your first message.
Echo-9 is a linear satellite downlinking in the 11.7-12.2 GHz range. All the other Echo sats are DBS circular polarization sats, downlinking in the 12.2-12.7 GHz range, as are the DTV and NIMIQ satellites. For those sats, (on which most things are encrypted and not FTA BTW), you would generally need a DBS lnbf, such as a single satellite DTV lnbf. For those LNBFs, you'd use a LO freq of 11.250. Ie the LNB settings are determined by the LNB not by what satellite you are trying to receive.
However you can often get reception of some of the few FTA signals on the DBS sats, such as NASA-TV, with a linear lnbf, but it will be difficult and may cut in and out, because a linear lnbf won't separate the nearby signals of opposite polarity, plus the signal strength will be cut by at least a factor of 2. However it can be done, although it helps if you have variable polarity skew rather than just H/V, and it helps to have a bigger dish to compensate for the signal loss.
