Subject: [TVI-RFI-EMI] BrightHouse & RFI?
Message-ID: <48AB2ECE.1060008@kd4e.com>

Has anyone noticed a pattern of BrightHouse cables
and increased RFI?

They have come into this area and where there used
to be a lot of interference to AM-BC when driving
around it has now become pervasive and severe.

It is so obviously from the lines that changing
lanes away from the lines diminishes the noise.

It used to be that we could go at right angles
to the main road then down our private dirt road
and find RF-peace but they've come up our road most
of the way and polluted that area as well.

Fortunately our QTH is 500 feet off the road so the
increased background RF-pollution is almost
indiscernible.

Hi
     I am not familiar with the term BrightHouse cables. Could you please
describe them to me?
     Thank you.

God bless,
Mark

BrightHouse is a local (Tampa Bay area) cable TV
and Internet provider.

I thought they were all over the country, apparently
not!  :-)

O I am sorry, I  didn't know. We have dish here at the house. I guess I am 
out of the loop. I do know that when I lived near cable I used to be able to 
pick up some channels just out side the UHF ham bands but that doesn't help 
in the current topic of conversation.

God bless,
Mark

In the "old" days with analog cable TV channels, the cable companies had an
extra incentive to keep RFI from their cables low:  When the cables radiate
anything, there is also ingress into the cables (from broadcast stations,
from ham radio operators, and from other 2-way radio services), and this
tends to cause herringbone and other interference problems to their own
customers.  So it was in their best interests to use well shielded cable and
to keep their cable plant in good condition; and in some cases (or so I've
read), that was enough to keep them on their toes and fix any leakage
problems before people had a chance to complain about interference from the
cables out.

Now that digital has or is replacing analog NTSC on many cable systems, I
fear that this particular incentive may be largely gone.  The digitally
encoded signals tolerate more RFI ingress before anything goes wrong for the
cable customer.

Wouldn't this argument also apply to the television set manufacturers?
 I mean, you would think it would be in their best interest to shield
from ingress too, but anecdotal evidence suggests otherwise.  Ask my
next door neighbor :-)
