OK, thanks.
Ahh... "BC" I can see that. Just hadn't ever heard that term before in reference to AM. (Learn something new every day.)
I'm guessing the tone would have been used to switch back and forth while listening to either music or speech, for whatever was the most suitable tone.
When I put the supposed "PM" under a magnifying glass... all I can see the vertical sides of that letter, so it probably is an "H" as opposed to an "M."
Thanks Ron.
