This comes under the category "unintentional radiator" and there are legal
limits that must be met. One problem I can see is that the equipment could
be tested and approved without wiring it into a "system" and it might meet
the requirements, but when fitted with all the accessories it may not, but
these may be deemed to be in your domain not the manufacturer's (I'm
guessing and supposing).
You need to find whether the interference is coming directly from the box
(unlikely in my view) or is radiated from attached wiring, most likely.
Snap-on cores on these wires, including the supply wire to the wall wart,
should cure the problem. You may need more than one pass through each core;
up close to the router.

Do they have the license to emit this frequency, or just use it internally
inside some equipment?

I have been hearing this for many days in row now and doing a Google
search on
it I found some disturbing info. It seems that this freq. is being used
for
telephone equipment. Intel among others has applied for patents using
this
frequency.
Does anyone know what the signal I am hearing on 14.030 MHz actually is?
Thanks,
Jack, AE6GC
