        Ah. I forget Lemmy has a wider international range. To be fair, some American AM stations were known to bounce all over the world.

          I forget Lemmy has a wider international range.

          Thanks for acknowledging that. Too often I feel I have to justify myself for - well, anything that puts me apart from US Americans.

          some American AM stations were known to bounce all over the world.

          Are you sure you don’t mean shortwave? According to this article the furthest for AM is ~1000 miles. That’s 1/5th of the way to Europe.
