Default HF noise from new electricity meter?

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?
