The System Info window is a summary of your receiver's info, including Receiver Serial #, Smart Card #, etc.
In my post last night I gave you a Step by Step procedure for your model 522 receiver to change the Channel from 73 to something in the TV UHF range of channels 21 thru 69. I also linked to your receiver's Manual on-line.
You may try a higher cable channel.
What I was suggesting is to switch from the cable channels to the OTA channels and as they only go up to Channel 69, try a lower channel - one not being used locally nor adjacent to one in use locally already.
Then change your TV2 to match.
