I agree. This mostly falls under the Part 15 rules where it says in
general; "they must accept interference but not cause interference,
etc". It boils down to a cost point. In other words, they are using
the cheapest box that can be purchased to meet their requirements.
I've held their feet to the fire on the point to where they acknowledge
they have no choice in hardware or technical expertise that can or will
resolve the issue.
My other and older receiver worked fine with no issues until lightning
took it out. They replaced it with a new one which has issues. In
other words, "we would love to keep you as a customer but we can't fix
your problem". The old receiver had an external connector for the RF
remote receiver. I removed the antenna, terminated the input and
switched the remote over to IR remote control. The new receiver has a
built in antenna for remote control and thus it has a plastic box.
Even on IR remote the RF receiver is still active. Projcet cost down
........ grrrrrr!

This is an example of what I was talking about (quoted below) that I
can't think of any mechanism whereby ANY ham rig is the CAUSE of RFI,
and an example of several common mechanisms within those systems that
make them susceptible. Their equipment and systems SHOULD reject or
signals and fail to do so, thanks to failures in design,
manufacturing, and/or installation.
In other words, it is ALWAYS their fault.

John,
Very informative. I intend to throw it in the face of the next AT&T
salesman that comes knocking on my door. We get one every couple
months.
It is especially true that they lie about now being pure fiber to the
house. I ask them how they installed fiber without having sent out a
machine to route it.
Not mentioned is the RFI that their modems can generate. Reading the
article confirms that it is almost a given-- especially for those
with overhead utilities.

May find some information about the issue here:

It will depend on which VSDL frequency is being used by the modem. My
modem seemed to pick the high end of 40 meters most of the time.
