Ooch my TVs signal hurts!

I will try and keep this simple.
Very small town (<2000 population)
no control over my cable provider (apartment)
next nearest city 120 miles

Okay, so we get about 28 channels and most are okay at best. However the Discovery channel is nearly unwatchable.

If the picture has anything very white then all you hear is a loud scary scratching that drowns out all audio.

So can anything help? Boost the signal or ??

Alpine, Texas --- take a turn once you past the three brown cows and drive until you run out of gas, then your here.

Not an option. Dishes are not allowed.

I really just want to understand why the white part of the signal is transmitting very loud trash audio and how I can fix it. Is anyone here experienced enough in broadcast transmission to understand the problem I am describing?

Kenglish - Thank you
Yes all of us (apartments) have the same problem. I don't know if it a SMATV system , or even what that is, but we only have a single cable company in town.

So would it be a problem that our local company can fix, or is it an upload error from Discovery channel?

So in case no one here locally can fix it, can I do something on my TV or add a inline filter thing to fix it? Reason I ask is that I think the Discovery channel has been like this for awhile now.

I contacted the local cable company but they act like I'm speaking a foreign language. "Fixed Locally" is that my local cable company or someone else?

Oops sorry, here is the cable company or provider.
