I am going to see if I hear any of the signals Bob listed on 10.  I have not 
had any 6 meter gear since 2005 so cannot check that band.  I do have a lot 
of what I thought were birdies on 10 now.  I know both my Icom and Yaesus 
have a strong internal signal on 28630 but I di hear fuzzy/buzzy signals 
every so often on 10.

I can't speak to Uverse or AT&T.  We gave up AT&T as we have had fiber optic 
cable in our area (Peachtree Corners) for a long time.  The only DSL they 
offer is ultimate which is just above DSL lite.  My son is a gamer so we 
went with Comcast
for the 10 times faster speed.

I do remember way before Comcast and even media one to the first cable 
provider and they had all sorts of ingress problems.  But you could call the 
Engineers Office and someone would come out.   I quit packet back then as 
our SEDXC packet frequency was right in the middle of channel 15 which was a 
premium movie channel.
When I sent a packet spot I blanked TV's for many blocks.  But the engineer 
would come out and try to find the problem.  Back then the FCC office in 
Atlanta assisted as did John who is now NP2B as the Atlanta Radio Club TVI 
specialist.
The Bellsouth engineer told my neighbor that my getting into her phone was 
MY fault.  The FCC engineer wrote a letter to her saying it was her phone's 
fault and not mine.  John liked it that I offered to lend her my Western 
Electric 2500 which is virtually RFI proof.

Comcast won't let you get to their engineering people.  Another local tried 
contacting the Local Govt rep who was supposed to be the go between
Concast and customers problems and that did no good.  Comcast finally 
responded and fixed the problem after the Riley of the FCC sent them a 
letter telling them they had 60 days or so to solve the problem.

Back then you could drive around and listen on 107.8 FM and if leaking there 
would be a squeel
and a siren.

Its even worse than with the power utility companies which is threatened by 
FCC fines for not curing line noise.  The past several years letters to 
Executives at power companies dominate the FCC notice page.  Seems the power 
companies
leave it up to the overworked district engineer who usually only has the 
CB/10 meter hand held with a whip to find the problem.  I know the district 
engineer relies on hams with better equipment to at least get them within a 
pole or two.

Good luck on working with Comcast or AT&T.
