What pre war TV looked and sounded like

[David Roper]

Ummm . . . have you ever seen a prewar TV operating? Ever fiddled with the fine tuning on one to bring in the sound? I have...and your "simulation" is greatly exaggerated. And let us remember that my experience has been, of course, tuning to receive FM sound with a prewar TV's AM detector. While the comparison in that case to tuning shortwave is reasonable, your description is still exaggerated, and tuning the original AM modulated sound carrier would've been quite a bit less critical still. And if you don't have intercarrier sound (no prewar TV did), you don't get intercarrier buzz!

The BBC used the television sound channel without video for years to broadcast classical music. They got along without FM sound until color came in.
