72 w

[quasimodem]

my true south is 72 w.
lately, I've noticed very heavy pixelization at times. at first I thought it was weather, as we've a a lot of snow this winter. I've been able to get the snow to drop off of the dish by swinging it east and west.
but last night the sky was perfectly clear. I tried bumping the dish a degree or two east or west to tweak the signal quality, but it never changed.
still, it was at about 30 (which is usually more than enough for my Viewsat Ultra).
then I shut off the receiver for about 5 minutes. to my surprise, the picture came in crystal clear when I turned it back on.
can anyone explain why this may be happening? could there be some sort of static charge that builds, that is released when I shut off the stb?
my cables are all rg6 and only about 4 months old...my dish is grounded well.
thanks

Sounds familiar with a Viewsat.

The power level on 72 goes all over the place for me on my Coolsat 7000 with no discernable correlation to my weather. Supposedly the satellite has problems and that's why NASA moved their channels off of it, but that was C-band.

I had an LNB once, that every time the temp got down to 15 deg, it would go into oscillation, and I'd lose reception. If I'd unplug the receiver for just a few seconds, it would be fine when it came back up. I could always tell what the temp was outside, as it happened every time it got to that temp. I lived with the LNB for a couple years, but finally replaced it.

thanks BJ, it was about 15 degrees out last night...
my lnb is a four month in service Invacom qph-031...
perhaps this is the problem...maybe I'll try another this spring when I can get up on the roof....
(I could probably use my ice climbing crampons, but I think my roof would suffer dearly lol.)

I bought a qph-031 a couple years ago. It sort of died on the 2 ports I was using, so I switched to the other two ports, then they sort of died, so I bought another one to replace it. Then, the lnb on another of my dishes died, so I decided to try the old broken 031 again. The darn thing worked, as good as it ever did, and I'm still using it today. I get the idea that the qph-031 lnbfs must not be sealed very well to the weather, and perhaps moisture gets in, and if you bring it inside to dry out for a while, they come back to life.
That rain coming in might put a dent in the snow on your roof. Last 2 years, I could walk up the snow drifts onto my roof. This year the roof is 8 to 10' off the snow drifts.
