Loosing Satellite signal in Chicago Western burbs

[Hytops]

For the past week, I continuously loose my HD sat. signal for the following stations.
ESPN, ESPN22, DSC. The picture cuts in and out with the message stating looking for satellite etc.
What satellite do they originate from. I am guessing 119?
Should i call for a Tech. to come out to realigne the dish?:tux:

I had the same problem but only on ESPN2HD,HDnet & DSC but it has now cleared up for me. It seems to happen every springtime for a couple days. It was only Sat B. Here is a list of what is on where transponder & LNB wise.
