A woman was speaking in badly accented Russian(??) for a moment just
before sign off.

I understand Polish (slowly) and can recognize Russian, but the
woman's language was a very stong regional accent or dialect, not what
you would expect from a Muscovite.

Does anybody have any idea of who or what I was listening to?

It wasn't a Radio Rossii or some other regional outlet, was it?
