I noticed some picture pixelation on my bedroom HR22 the other day. I decided to check my signal strength and I started on my living room HR22 which I haven't seen the pixelation.
Living room (good picture): Lots of 80s and 90s on the 101 SAT with the 4th column reading zero and the 2nd number on the bottom row with a zero.
Bedroom (pixelating somewhat): Same 80s and 90s but now I have 3 or 4 zeros on each row!
These two HR22s are on different sides of my SWM16. Also on the bedroom side is my basement HR22 and it shows many zeros in the signal strength as well and it takes a long time to tune a channel.
Could it be one side of my SWM16 is bad? Or just loose connections? I haven't changed any connections since I hooked up an HR34 (to the good side) of the SWM16 almost a year ago. BTW the HR34 has shown a good picture as well.
