PMB has your signal frequencies. You can find the frequencies you are looking for on Lyngsat.com for Sat 97.
It is always difficult to get the dish aimed right for the first timer. Can you confirm your angle and azimuth of the dish? What is your zip code, and what angles are you using? Do you have a motor?
I find it easier to try to calculate the dish angle above the ground for the 97 using dishpointer and the manual for the dish, or dish and motor. Find the general direction it is suppose to be pointed to and get that as best you can. Then with the receiver and a tv next to the dish slowly move your dish in one degree increments east and west to find the signal, and then find the strongest signal. Once you find it east and west, adjust the angle of the dish above grade to strengthen your signal.
Good luck.
