Signal strength question

[mheckman]

I'm getting a lot of pixelation and signal loss on some channels (esp. on the 129 satellite), and seem to have quite a low signal, but only on 1 receiver.

On my 722, I'm getting a signal in the low 30s (on a scale up to 125). The 110 and 119 show a better signal, but still only in the upper 40s.

On my 211, I get 82 on 110, 74 on 119, and 64 on 129, all on a scale of 100. And I'm not seeing the same kind of pixelation issues on that TV.

I know that the signal numbers don't always correlate directly between receivers, but they seem drastically higher on the 211 than on the 722. I did a "switch test" on the 722 and it came back all OK.

What should I be looking for - loose connection on the coax somewhere?

loose connections, bad fittings, moisture in fittings, low frequency barrel connection in line or at wall plate.

No loose connections unless it's inside the LNB (didn't take that apart). It used to be OK, so I don't think it's a low-frequency connector. Moisture is a possibility I guess. Although there are only a few cable-to-cable connections:
o Dish feed to block outside house
o Outside block to garage attic
o Garage attic to wall plate
o Wall plate to receiver

I decided it was too cold to futz around outside or in the attic, so I have a Dish tech coming out in the morning. He'll have tools to tell where the drop-off occurs, where I'd just be guessing (and freezing).

Turned out to be a bad receiver - just had my old 722 replaced last year, now the new(er) one died. Replaced with a 722K.

I am glad to hear that this issue was able to be corrected. Please feel free to send me a PM if you need assistance with anything else.
