I have an old TV, but notice that many shows broadcast for a wide screen picture nowadays. Often I can tell that the ends are cut off of my square shaped TV screen.
I hope I’m not missing much. Just noting that I’m way behind on the changes in TV, what with wide screen and hi def or whatever other terms which I don’t even know what they mean.
Ditto with radio broadcasting. I’ve noted some radio stations give call letters then also note they are on an HD channel. I am not familiar with that either. I only know about AM and FM. Heck I have radios for which the AM dial only goes up to 1600 kilocycles.
I know I’m behind the times on some of this but also not sure I’m missing anything. Somebody told me to ditch satellite TV and get Netflix instead. There too, I don’t know what Netflix would add to the quality of my life.
Oooh, that really Hertz!
“Heck I have radios for which the AM dial only goes up to 1600 kilocycles.”
The dial stops at 1600 because AM frequencies do not go above 1600.
Above 1600 you have the short-wave frequencies.
