I dont have another receiver but the customer is going to find/borrow one
this week

My former boss I havent seen in 15years, he worked in radar systems setup
and maintenance in the military for ? years then had 2 successful satellite
shops in the 80s. I worked close with him, when he said a dish had some
problem or diagnosed something, I recall in about 10 years he was right
about 100% of the time. So I know that he was very good and customers knew
it.

But we went different ways because the markets just changed, people used to
pay $ to fix tvs and stuff, then they went to the small dish, which didnt
move and seemed to work well. tvs and vcrs are disposable, you cant charge
$200 to fix stuff these days that costs $89 at Circuit City to buy new

Back in the day, my former boss would have all kinds of extra receivers but
when you sell the shops and have to get rid of inventory?

I like the older C band systems but have direct tv, if people can afford it?
its easy and the pix is great

I mean the ABC that comes in on G5, the dish will not move, I only need to
position it on ONE satellite. Other satellites may have worked better but
still had some static.

Right, the dish is not damaged, its been in one location for many years, its
tight and the inclination bolt clearly hasnt been moved in years; the feed
is clean, there are no trees, no phone poles, nothing in the sky its a clear
shot to where its pointed

Thats a great website thanks. Nobody seems to know what reflects microwave
noise. If Verizon installed a microwave repeater 6 months ago? I want to
build something to block the microwaves

so I figured a 4x8 CDX, coated with aluminum foil on one side, then ***
metal, will work. Im going to try this after we try another receiver and
bypass the cables

If the power supply was vershtunken? Well I havent measured the voltage to
the LNB I dont get many calls for C band anymore. But some channels are
clear with a sharp pix. espn is clear but with lots of white it makes
noise. Is there a word for that? I dont think its white noise its like
the video bleeds over into the audio band when the video is peaking
