I noticed recently that I was receiving a new kind of noise/interference
on certain shortwave frequency ranges. It seems to be an unmodulated
carrier which repeats at 43-Khz intervals throughout a range of several
hundred KHZ. It's most noticeable in/near the 25-m band from about 11200
to 12400, although I've found it at weaker levels in other frequency
ranges.
I got to thinking about the possible source of this interference and
remembered that the local power company recently replaced my home
electricity meter with a new remote reading digital meter. Is there any
documentation on RF interference from these meters?

If you are in Europe then all new electrical equipment should be EM
compliant and not generate interference. The meter should have a CE mark
indicating amongst other things that it complies with the EMC directive.

If the meter has a CE mark and is generating interference then it is faulty.
If it does not it is probably illegal. In both cases the power company
should replace it.

If you are in the US then I don't know if there are any regulations on EM
compliance.

Yes, there are but it is kind of a catch 22. The FCC part 15 regulations say
that the device must not radiate harmful interference. Problem is, shortwave
receivers are also part 15 devices. The last part of part 15 states that if
the device is interfered with, it must except this interference. If he is a
ham, he is better off. As a ham, his radio would be considered part of his
station. If a device is interfering with a licensed radio station, it must
be fixed or removed from service.
