Hi:
Let's say I am in a space station which has a supercooled 150 KHz DX
analog receiver that receives the magnetic fields [while ignoring the
electric fields] of extremely weak 150 KHz AM analog carrier signals.
In addition, this receiver is so sensitive and powerful that it can
clearly pick up AM carrier waves as weak as 10^-10,000 watt [i.e. 10-
to-the-power-NEGATIVE-10,000 watt]. Also, this receiver has an
astronomically-powerful amplifier which amplifies the extremely-soft
carrier waves until the resulting modulation signals will be just loud
enough for the human ear to detect. Following this amplification, the
carrier waves are demodulation to modulation waves - the stuff we
"hear" - and then sent to loudspeaker so those onboard can hear those
sounds. In addition, all the audio devices filter out modulation
signals that are below 20 Hz or above 20 KHz [after reception, before/
after amplification and demodulation], as the human ear only responds
to 20-20,000 Hz.
If I am on this spaceship, what will I hear on the radio? My guess is
that I would hear long-distance magnetic disruptions. Would these
magnetic disruptions sound like the high-pitched, terrifying
heterodynes that resembles the sine-waves tones of the Emergency
Broadcasting System?
Thanks,
Radium |

An OLD FART which you are, will hear only from 40 to 8000 Hz.

So, what is your question?

How do the high-pitched, terrifying heterodynes, that resemble the
sine-waves tones of the Emergency Broadcasting System, sound?
Post an MP3 somewhere, would you?

EBS tones have been discontinued for many years now in the US.
"high-pitched, terrifying heterodynes" could be some types of bluegrass |

Yes; now we use something else that sounds even worse.
The current sounds remind me of some sort of low-speed
modem, as opposed to the two-toned whine used previously,
which sounded like a mutated dial tone.

Nope. Whenever an emergency occurs, first they play the boring low-
pitch square-wave tones. Then they play the high-pitched, terrifying,
psychedelic sine-wave tones I described. These high-frequency,
heterodyne-resembling tones are so mind-altering that they make my
eyes water. Yet I enjoy them. Things that are scary can also be
pleasurable at times. Why do you think they have roller-coasters?

You will hear a voice instructing you to drill a large hole through the
side of the ship. Do this and write back for more instructions!

There is no "Emergency Broadcasting System", Troll.

That is EXACTLY what it is. An oddball, low baud rate modem. It was
done that way to make it addressable, and to keep it from being tampered
with by hackers or terrorists.
