That's pretty routine for me. I live 150 miles south of Chicago, which is
the closest city with much VHF activity. Someone may just happen to have
their beams pointed my way and I hear them, but they work someone closer to
them and then point their beams north or west. There was some enhancement
in this area early on and I heard several stations who disappeared and I
never heard them again.
