ky03,
Make sure if your using a fixed dish (without motor) that you have the proper tilt of the lnb for that sat. There are some great charts on
Sadoun's site.
Your elevation must also be set perfectly.
Also, another tip I'll give you: leave it on one of the TP's that you can receive then go to your dish and very gently move the dish side to side looking for the maximum that you can get that signal. Once you have the highest it will go then try very small adjustments to the elevation both up and down.
When your sure it's at maximum, then go try the other TP's.
Let us know how it works. If you got some your only a tiny movement away.
