Hi, I am new to dish (been a customer for about a week). I had an installer come last Wednesday to install my dish and receiver. I got the 522, which seems to be an nice system, but I keep having problems with the 2nd tuner. On my main TV which is connected to tuner 1 I don't have any issues, but on TV 2 (tuner 2) I don't receive channels in the 160's and 170's. I do a soft reset of the box and sometimes a hard reset. It sometimes fixes the issue for a bit but I usually have to reset it ever day. I have given up on watching anything on the 2nd TV in the 160 and 170 range. I talked with Dish and they are going to send someone out next week, but I was wondering if anyone had an idea of what might be causing this. I don't think its an obstuction issue since the dish has a clear line of sight and tuner one does not have an issue. Thanks in advance for your suggestions.
