You might get more responses if you go into the What's Up There section and ask about a specific feed you're trying for. We can then check and give you feedback if we're receiving it or not. That will give you feedback whether it's a tough one or not.
In general, peak your dish to receive the NBC transponders, then you'll be prepared to receive other transponders on 103W Ku.
To be able to post in What's Up There, you need to request that from KE4EST.
ADDED: Can you receive the NBC feeds on 11910 H 4600?
