TV audio is not a sub-carrier. The audio is an independent transmitter from
the aural transmitter.

They may have come up with some other way since I worked at WXEL in the
fifties, but as a fifty's TV set still works today, I suspect the result is
the same.

You guys are testing my gray matter today...
The question: Is it possible to detect an FM subcarrier without
receiving the base carrier?

Perhaps another cup of coffee will help...
