Tesla Nonsense

"It's interesting to note that Marconi's first successful test was using a Tesla coil".

This is nonsense. Marconi's early tests used a simple induction coil known as a Ruhmkorff coil. Nothing remotely to do with Tesla. I have removed this spurious claim Gutta Percha (talk)

Radio amateurs

Main article: Amateur radio

Radio amateurs are individuals who have undertaken an examination to prove competance in the use of radio transmitters. They are licensed to operate on a number of allocated bands in the Radio frequency spectrum. The power of their equipment is restricted, and they must not cause interference to the reception of authorised broadcsasts. They may not broadcast themselves, or communicate with the public with their equipment. They are only allowed to communicate with other licensed operators. They are issued with a unique identifying call sign which must be sent at intervals during their transmissions. They are regulated by an International body which agrees the allocation of channels available to each individual country or region of the world.

Suggest merge

Radio communication system talks entirely about ...radio. The subject of this article. Perhaps, if it's all right with you, we should merge these two articles so as not to waste the reader's time skipping about trying to piece together a coherent overview of the subject. Of course, giving due copyright attribution where legally required...--Wtshymanski (talk) 07:56, 3 January 2012 (UTC)

Well merged Wtshymanski! Martin Hogbin (talk) 20:52, 11 January 2012 (UTC)

I've often observed that we make the reader reassemble the broken souvenier ashtray of knowledge by gluing together the splinters of fact combed out of the deep shag carpet that is Wikipedia. Two shards are now stuck together. For now. --Wtshymanski (talk) 15:34, 12 January 2012 (UTC)

Definition in lead

"Radio is the transmission of signals through free space by modulation of electromagnetic waves with frequencies below those of visible light."

So a radio set can use signals using infra red radiation just below visible light? I would like to see an example. In fact I will tag the claim as 'dubious' and unless an example is provided, a more modest claim will be added. 109.153.242.10 (talk) 16:40, 25 January 2012 (UTC)

So how would you phrase this? --Wtshymanski (talk) 17:05, 25 January 2012 (UTC)

car radios

My 1990 car's radio only goes to 1620AM. Were there improvements after that which allowed AM frequencies to go up to 1700? — Preceding unsigned comment added by 71.235.127.87 (talk) 22:10, 31 January 2012 (UTC)

Guglielmo Marconi?

I am surprised that there is even a discussion around the paternity of the radio invention that is worldwide recognized as belonging to Guglielmo Marconi. This is one more example of how twisted is the information found on wikipedia. — Preceding unsigned comment added by 193.32.30.67 (talk) 15:25, 22 February 2012 (UTC)

I totally share your thought. I've been trying for a long time to restablish the historic truth about the radio invention, but all my attempts seem vain either if I back my informations with the most authoritative sources or I fully explain my position on the Talk section of the article: I'm alway regularly blocked. The basic position imposed in all the articles regarding the radio and his invention is: Tesla invented it and Marconi was just a fraudster. This is a historic "monstruosity": Tesla should deserve just a line and not more in any article regarding the radio considering his contribution to the development of the invention, while Marconi should be the main protagonist. In all the wiki article happens exactly the opposite. Just to remember you that just few months ago Marconi in the "History of radio" was briefly remembered as: HE COMMERCIALIZED THE RADIO

I've never read in any other inventions article that the inventor who devised it shouldn't get too much credit because he didn't invent nothing new since he used components and idea developed by others. It would be like reading in the Wright brother article that they didn't do anything new because the propeller and the wings had already invented or that Ferdinad Benz shouldn't be credited with the creation of the first car because the internal combustion engine and the wheels (maybe invented by Tesla too) had already been conceived. This denigratory approach is used only for Marconi and is totally scientifically groundless. Marconi's apparatus was totally original and didn't have nothing to share with that one of Tesla of anyone else, yet it was not possible for me to explain the technical difference between the Marconi and Tesla systems. My dear, it's a hopeless battle. I'm just sorry for all the young people getting wrong informations after reading all the articles regarding the radio in wikipedia.....Magnagr (talk) 21:37, 22 February 2012 (UTC)
