I knew of two websites that would tell you what the signal strengths were and which direction they were coming to you at. (Poor English, sorry.)
I just looked and only found one: tvfool.com. But it'll tell you what's going on.
Check it out and drop me an email if it's not clear enough. One thing that's strange till you get used to it is the state of the call signs and frequencies. Again, drop a line if it's not clear.
