Introduction

You're listening to the Skeptics' Guide to the Universe, your escape to reality.

S: Hello and welcome to the Skeptics' Guide to the Universe. Today is Wednesday, January 2, 2013, and this is your host, Steven Novella. Joining me this week are Bob Novella,

B: Hey, everybody.

S: Rebecca Watson,

R: Hello, everyone.

S: Jay Novella,

J: Hey, guys.

S: And Evan Bernstein.

E: I have come to chew bubble gum and kick ass. And I'm all out of bubble gum.

J: Evan, can you say that again, but do it twice as corny.

(laughter)

R: Yeah, no.

B: Impossible!

R: You're no Rowdy Roddy Piper.

E: Right? They Live. That movie. Gosh. Is that one of the worst movies ever?

B and R: Worst?

R: It's one of the best movies ever, are you kidding?

B: Oh, god, I love it.

J: It's a cult classic. I mean, yeah, it didn't hold up as good as I would have liked, but it's still

B: Oh, what doesn't hold up?

J: Whatever. It's still great. It's still good.

R: It's awesome.

B: The best bare-knuckled brawl I think in any movie.

E: I'm sorry. Look, I get campy and I get, you know, yes, I get the brawl scene. It was rated like one of the best brawl scenes in movie history and so forth. Rowdy Roddy Piper, John Carpenter directed it and all that. I'm sorry. That movie had so many flaws to it. I mean if we were ever to do a review of that movie, oh man, we could do a whole episode on that.

S: Maybe we should.

E: Maybe we should.

R: Yeah. I will defend that movie with my life.

(laughter)

E: All right. I'm gonna be your Gene Siskel to your Roger Ebert or vice versa, or whatever.

R: Oh, boy.

J: Steve, I'm getting a feeling like in the back of my head. I feel like I'm predicting that we're gonna do a show on predictions.

S: I know, I think you're right, Jay.

B: Damn, you're good.

E: One of these days.

S: It's a high probability hit.

This Day in Skepticism (1:43)

• January 5, 1940: FM radio first commercial broadcast

S: But first, Rebecca's gonna tell us about January 5th.

R: Happy birthday, FM radio!

J: Awesome!

E: To all the kids out there.

J: What does the "F" in FM stand for?

R: Frequency.

B: Frequency modulation.

J: Thank you.

R: Yes, sort of. You could probably pick any number of dates for the birthdate of FM radio, but on January 5, 1940, the first network program was broadcast on FM radio. It was called "Colonel Harrison Featherbottom and the Fart Man's Morning Zoo Hour."

(laughter)

E: What? No, it wasn't.

B: No way. I don't believe it.

J: I love it!

E: . . . skeptic.

R: Okay, that's not what it was called. But it was a 60-minute show that was, it was designed to showcase several different types of audio and vocals and stuff that would eventually be broadcast. The show traveled from a station in Yonkers, New York that was operated by one C.R. Runyon, to a transmitter in Alpine, New Jersey operated by Major Edwin Armstrong of Columbia University, who was heading up the effort; and then onto Meriden, Connecticut; Paxton, Massachusetts; and then finally Mount Washington, where it was transmitted by telelphone wire to Boston and then back to Yonkers. By all reports the FM broadcasts were found to have no apparent loss of quality. So, it was given the thumbs up. The first FM stations that had regular scheduling, programming, appeared later that year. FM.

J: That's cool.

S: Yeah. So, Jay, frequency modulation, that's how the information is encoded in the carrier wave, by modulating the frequency of a signal. As opposed to AM, which is amplitude modulation, they modify the amplitude of the signal.

E: Thank you, Dr. Marconi.

S: Right. And the FM band simply refers to, the FM has nothing to do with any frequency range itself, any band, but that's just the band that's assigned in various countries to transmit FM signals over. So in the U.S. and most places it's 87.5 to 108.0 megahertz.
