No. Except for brief periods during wartime, radio receiving equipment has
never been regulated.
Only transmitting equipment is regulated, for the purpose of keeping things
orderly enough so that no transmitter will interfere with the signals of another
one.
(Personally, I think some receiving equipment should be regulated, specifically
speed radar detectors. But that's just my opinion; I could be wrong.)

Transmitters before 1924 were long wave transmitters this is the lowest band in the RF spectrum 148.5 to 283.5 kHz. Propagation of shorter wavelengths was not understood until the shortwave experiments by amateur radio operators in 1923 and by Marconi in 1924. Spark-gap transmitters were used prior to World War I, until the development of powerful Radio alternators by General Electric just prior to the war. Vacuum tubes began to be used to generate radio frequencies in the mid-1920s. After 1924, use of long wave radio for long distance communication began to decline, as much less expensive shortwave transmitters began to carry increasingly heavy volumes of long distance communication. A period of explosive growth of shortwave communications began in 1927, leading to rapid decline in long wave radio usage.
It's just what it sounds like--a license that restricts your privileges. Most of the people who have these are pilots or mariners. If you're a pilot who has a restricted license, you can use an aviation radio only if it's in an airplane. You can't put an aviation radio in your car, or in your house, or walk around with it and talk on it. Same deal with marine radios--you can use a marine radio in a boat but not on shore. Yes, there are handheld aviation and marine radios. The tradeoff: they are good for life.
It depends on where you live. Just go to www.radiodisney.com and check your local radio Disney station. Or if you have music choice on your tv you can listen to radio Disney via TV.
Radio and television are similar in that you can hear music on both of them. They are different because a radio does not have a picture on it where you can watch what is going on.
AM stands for amplitude modulation (the kind used in the am broadcast band and also on the shortwave bands).The shortwave bands begin just a little higher than the top of the am broadcast band and go up to 30000 KHz. The am broadcast band is from 530 to 1700 KHz and shortwave broadcast bands begin about 2000 KHz. The programming on shortwave stations is many types such as cultural,news,science,and just about anything about the country which the station is broadcasting from.Between the shortwave broadcast bands you can also hear amateur radio operators,military,utility stations,radio beacons,pirate broadcasters,radio telephone,aircraft, radio teletype,and lots more.The higher bands (above about 9000KHz) are daytime bands because the signals there propagate around the world in the daytime and the lower bands below about 9000 KHz are nighttime bands and you listen there from about sunset to sunrise.I could go on forever but that is probably about as you want to know about it unless you have ever listened, once you have experienced shortwave listening when conditions are right, you will be hooked on a great hobby.
LF-RF or low frequency radio frequencies. This spans frequencies from just below the AM radio band through the shortwave radio bands.
Short wave as in shortwave radio just means waves of a certain wavelength . The wave is usually made by ovilators and tuned circuits. In a shortwave radio you generally tuned the final resonating circuit to the specific frequency . Now the radio probably uses PLL technology to generate the wave
You can only do this if: 1) your MP3 player has a built-in radio tuner, or 2) you are in a wi-fi zone and have an app that can listen to internet radio, or 3) you have access to a data plan that can listen to internet radio via a cellphone network (not recommended, as you will be paying a lot just to listen to radio).
Yes, use ooTunes. The station just has to have a radio stream (most do).
No, there are applications from many radio stations from all over the nation, as well as from foreign nations. Just download them from the store and listen.
you get an app like Pandora or klove but they need wifi. just type in "radio" in the app store
A clock radio system is and alarm clock that has a radio built into it i have one and they are get so you dont have to listen to just beeping all the time it gets annoying...
No, its not hard. Just listen to the radio station for the announcement.
Yes. Try Grooveshark, Pandora, YouTube, or Slacker Radio.

Ultraviolet radiation and shorter waves are consider "shortwave radiation" they begin at about 300 to 350 nm (just past violet in the visible spectrum)
