Howdy,
I've been tolerating something here that is a nuisance for the past
few years: Tuning up through 75 meters, at around 3780 or 3790, the
band noise suddenly goes up 20 dB and stays there all the way up to
over 5 MHz. It's just white noise, like data. Does anyone else have
this? I suspect it is AT&T VDSL but I want to find out if there are
other possible causes. It's puzzling that only that one frequency
range has the noise since Uverse or VDSL whatever it is, uses a number
of other "bands" for data uplink and downlink. I have done nothing
partly, because the whole scenario of calling AT&T and getting to a
human who knows what I'm talking about will probably take hours and be
a frustrating nightmare but every time I tune down the band and have
the noise floor suddenly drop I get ticked off.
I guess I'm hoping someone else has had this problem and dealt with it
and can give me some pointers. If it is indeed an AT&T problem maybe
there's a secret phone number to get me right to a technician.
tnx and 73
