  Frequency allocation - Wikipedia, the free encyclopedia
Use of radio frequency bands of the electromagnetic spectrum is regulated by governments in most countries, in a process known as frequency allocation or spectrum allocation.
The range of "radio frequencies" is a matter of international convention.
At the international radio conference at Atlantic City in 1947, Hertzian (radio) waves were defined as electromagnetic waves of frequencies between 10 Kc/s and 3000000 Mc/s.

 Radio History: 1947
1947 was the second year of the post-war Baby Boom, and it was also the last year when radio would lack any meaningful competition: television was on the air in a few cities and was due to arrive in others very soon.
But radio was still king: in fact, more than 400 new stations were going on the air, many in small towns where a local station was of great importance.
Radio was cautiously raising the subject of racism, and a few local stations in the north and the midwest offered thought-provoking public affairs programs on the subject.

 Spectacular Structure in M87
The new VLA image is of the galaxy M87, which harbors at its core a supermassive fl hole spewing out jets of subatomic particles at nearly the speed of light and also is the central galaxy of the Virgo Cluster of galaxies.
The galaxy's radio emissions first were observed by Australian astronomers in 1947, but the radio telescopes of that time were unable to discern much detail.
Subsequent radio images, particularly those made using the sharp radio "vision" of the VLA, were primarily aimed at studying the inner 10,000 light-years or so, and showed great detail in the galaxy's jet.

 Radio: Bob Hope and American Variety (Library of Congress)
On the radio, a vaudevillian's tour was instantaneous, over the networks' telephone wire connections between cities and stations, rather than by railroads over the course of a year.
Wynn is said to have become the first radio performer to have a studio audience when he rounded up station employees to witness the broadcast because he found it difficult to be funny without an audience to respond to his humor.

 Lisa's Nostalgia Cafe--40's Radio & Records
A slower recording speed of 33 1/3 rpm was adopted for this purpose, and it became known as the "professional speed." Until tape recorders became available in 1947, radio stations and record companies used this speed for their transcriptions and wax master recordings.
When magnetic tape recording became available in 1947, one of its first supporters was Bing Crosby, who switched from NBC to ABC when the latter promised to let him pre-record his shows.
Gradually, the radio industry saw that tape-recording was a good thing, and by 1950 airing pre-recorded shows was a standard practice.

Two years later, in October 1942, Radio Saigon began to include POW news in its broadcasts and these reports were closely followed by government authorities in Melbourne Australia, and also by the legendary Arthur Cushen in New Zealand.
Arthur noted that Radio Saigon was heard throughout this period of two and a half years with generally a good signal on 11770 kHz.
The first issue of the World Radio Handbook in 1947 informs us that the station was on the air immediately after the war with two shortwave transmitters at 12 kW, the same two units that were in use before the Pacific-Asia War.

 The 1947 Crosley Radio / Bar / Ipod Dock
Not to go into to much electrical mumbo jumbo but a 1947 radio doesn't really like modern speakers (and according to my 15 second scribbled plans this project required a new speaker).
Wiring the lights, wiring the chassis, wiring the switches to the transformer, wiring the Ipod to the phono input, wiring the RCA outputs to the Ipod, and then rewiring half of this because I did it wrong the first time.
One stereo output for external uses and then one mono output that was sent into the old radio phono input.

By 1954 the new medium of TV was drawing the big money away from radio broadcasting, making it difficult to support expensive stars like Crosby with full orchestras and big-name guests.
