1076:"The diode is required or you cannot build a receiver" is absurd. Almost every radio built in the 1920s when radio began to flourish, had triode vacuum tubes and no diodes. Scan through "The ABC of Vacuum Tubes, An Elementary and Practical Book on the Theory and Operation of Vacuum Tubes, as Detectors and Amplifiers." by E.H. Lewis c1922 and tell me how many vacuum tube radio circuits you see which used a diode as a detector ... verging on none. In almost every case a triode with a grid was used as detector and for amplification. "Behind the Front Panel - The Design and Development of 1920's Radios" by David Rutland c1994 shows the exact same thing - pretty much only triodes. "Old Time Radios - Restoration and Repair" by Joseph J. Carr c1991, c2017 shows abundances of early radio circuits, pretty much all of which used triodes and no diodes. Once Doc Lee DeForest placed a grid into a vacuum tube creating a triode, and then Armstrong provided clear explanation for how a triode worked and then showed how it could be used in receiver and transmitter circuits, there simply wasn't much advantage in using a diode as a detector. Everybody designing radios quickly switched over to using triodes in their designs. Diodes offered a mere slight improvement over crystal sets and it was the invention of the triode and clever circuit designs by Armstrong becoming available, which caused the diode to virtually disappear, and the age of broadcast radio flourished. Today, a look at any radio circuit shows some form of transistors (the modern incarnation of triodes) being used in front ends, and no diodes being used as detectors. Fleming created a better detector alternative to the crystal set and little more. Nearly all of the radios we use today - vacuum tube or semiconductor - have as their practical origin point the inclusion of the grid and invention of the triode, which evolved into various forms of transistors. - Ed Scott, N6RFG, 3459:
contradict one another consecutively! I can only assume that this article has not been written to be user friendly to anyone who isn't a radio enthusiast and therefore already familiar with the subject matter. God only knows why Knowledge (XXG) allowed this article to be semi-locked for editing, but I'm seeing more and more of this across Knowledge (XXG) in recent months where people are just deluding themselves into playing at being historians and think they are "writing histories" by editing Knowledge (XXG). It's an encylopedia. If you want to write a communal project about the history of radio, buy a domain name and pay to host it and make your own researched website, add a forum so you can all bicker about whether there's too much about the US or not. Please keep Knowledge (XXG) true to its purpose, which is an encyclopedia which relies on verifiable information, not historical narrative written by bickering enthusiasts who refuse to share "their" article. Why ANYONE needs to be a gatekeeper (i.e. whoever is able to unlock editing on it) on such a shoddily written, rambling and incoherent article is really beyond me, they clearly don't have the time or inclination to do a proper job.
504: 2004:(nations of the UK, provinces of Argentina, etc.) don't matter? Delete all the crap about individual US states and Canadian provinces/territories and just add 'USA' and 'Canada' to the list of countries. I might understand it if the USA were the first users of radio broadcasting but they weren't (Argentina and Netherlands were). Maybe Knowledge (XXG) ought to be separated into an 'International English Knowledge (XXG)' (with intelligent and not dumbed-down articles) and a 'US English Knowledge (XXG)' full of pop trivia, explaining everything (London, which is in England... etc.)?-- 2906:...But the programme that is on the air in England is incomparably superior to anything to be heard here, for the B.B.C. provides the public of England with the largest return in education and in entertainment for eight mills a night ever provided, I suspect, anywhere in the history of the world. For it employs only high-class speakers, musicians, and entertainers of all sorts, so that the whole British nation is now being given educational advantages of the finest possible sort, at less than a cent a family a night, collected only from those who wish to take advantage of them. 4021: 4270:
inventors experimented with wireless transmission" again makes it sound like they were trying to attempt communication, they were not. Tesla was the anti-Hertzian wave guy (intentionaly so), so he should not be in the "Hertzian waves" section. There also seems to be a "20th century" section followed by a Digital era section followed by another 20th century section followed by another 20th century section followed by a Digital era section. Huh? Anyway, looks like there should be some basic encyclopedic cleanup.

with the economics of that. At that time, the majority of the radio broadcast audience lived in rural areas, where AM was king. I'm amazed he could make it profitable with only city populations for his audience. (The pre-WWII FCC back then regarded the VHF range as wasted spectrum that would never be of any value, so they parked him there where he couldn't harm the much more valuable and socially important, to politicians at least, AM broadcast business.)

174: 2881:, page 235. i don't know where exactly to place it in this article. in the german wiki, where i come from, we have a much more political and international focus on radio history. maybe someone can insert it in the proper space. there are two things i personally don't understand in the text, namely "eight mills a night" and "less than a cent a family A NIGHT" - what does "night" mean in this context? 636: 587: 714:
reflected signals to take over the receiver output as if a switch had been flipped. There was no apparent beat note, so no warning. Just from one second to the next, you'd shift from the local broadcast to one from hundreds to thousands of miles away. This wouldn't be apparent to the listener, it would just seem to him that his radio was broken, since there'd be no hint there was a second signal.

however Conrad had a regular schedule to broadcast music on his station as early as 1916. (If that doesn't count, KDKA had "regular" entertainment broadcasts before 1922 as well.) I believe the article should make a mention of the fact that the radio firsts are all murky at best regarding legitimacy, as there currently isn't one.

The article doesn't mention anything about the long delay in the adoption of FM radio. I've checked in a number of places in Knowledge (XXG) (especially around FM radio), but I haven't been able to find anything here, but I think it should be mentioned. In brief, the patent holders for FM were making

A side note: Frequency modulation at 42 MHz and lower was difficult to combine with carrier frequncy stability, too. Getting enough 'swing' while staying on frequency was a challenge, which gave Armstrong design difficulties. He eventually solved these with an expensive and complicated combination of

5) The experiences of other researchers (Lodge, Righi, Bose, Tesla..)were well known to the scientific comunity, yet their power transmission were limited to the laboratory's walls and none of them was ever hailed by their contemporary as "inventor of radio" !!! None of them received comments like:

The sentence, "In 1943, Tesla's patent (number 645576) was reinstated by the U.S. Supreme Court shortly after Tesla's death." suggests that the referenced Tesla patent was at some point invalidated, which is not the case. I'd like to see this section simplified, with a link added that points to the

As far as the FCC was concerned, TV was a much more important development than anything in audio broadcasting (after all, everyone still had AM radios and the only thing FM added was fidelity, important for music lovers with 'golden' ears) since it was totally new and the social and economic impacts

Before superheterodyne, there was tuned RF, which has a series, maybe three or four, LC filters with a tube amplifier in between. This means tuning each one, each time you change stations. I believe what people do, though, is mark on the dial for each one, the position for each station. (And there

Has anyone actually read the patent by Ward! It is pure crackpottery and has nothing to do with radio transmission but aims to collect 'atmospheric electricity' with a windward facing funnel. No mention is made of any aspect of electromagnetism or radio waves as they were understood at the time.
1045:
As long as you understand that Fleming's tube was a diode, a two-element device that rectifies (or detects) a signal, but it cannot amplify. DeForest's tube is a three-element triode that can amplify the signal appearing at the grid in the larger plate current. The diode is required or you cannot

Also the post-WWII FCC was far better staffed with competent engineers and they had to think about the future of radio in a way that benefited the public the most. During the war, the population left the rural communities for the urban manufacturing centers. This change in demographics was not lost
705:
After WWII, tremendous advances in vacuum tube performance allowed their use at microwave frequencies. Also inexpensive and stable transmitters could now achieve very high output powers at the VHF range. Since Armstrong donated the use of his patents to the government during the war, many engineers
4331:
There is no mention in this article that I can see of the superheterodyne circuit demonstrated by Armstrong in 1919. This was a critical invention because it meant radios only needed one tuner per radio, rather than a separate tuner for each station. It moved radio receivers from the toy of rich

Hi Maximilian: you asked what 'a night' refers to. In simple parlance: "per night" or 'per a night of programming'. In English, many rates are expressed on a daily or nightly cost basis, such as hotel rates: '100 dollars (or pounds) per night', discounting the fact that period actually normally

Tesla's supporters have been able to kill the history of science also in this occasion!!! What can we deduce from this crap article ???? So If we'd imagine all the protagonists of the radio invention parading in paradise (or hell, who knows it...),God seeing Marconi would ask: and who is that guy?
697:
1) Armstrong 'set up shop' in the 42 MHz region because the vacuum tubes of the 1930s couldn't work reliably at higher frequencies. Also, since the range was less at the higher frequencies and the transmitters more expensive and weaker, he would have a smaller 'audience'. He was already struggling

They do point to some problems in the article. The paragraph "The idea of wireless communication" jumps through several topics, needs to be broken up. Describing what Hughes did as "intentional" is bad wording, makes it seem like he was trying to build a radio system, he was not. "scientists and

There appears to be a bit of a discrepancy between the "Audio Broadcasting" and "Radio Broadcasting Beginnings" sections of this article regarding the "firsts." The most notable one is how the first regular entertainment broadcasts are currently credited to a station operating in the UK in 1922;

Things have improved, with more coverage of non-US milestones. Of course, a UK-centred view can be just as misleading, but the BBC was very significant. TV broadcasting, for instance, in the 1930s. Was it the first? What of the fuzzy line between experiments and regular broadcasts? But definitely

In television with AM video transmission, the onset of this sort of interference is easily seen when the signal strengths are more than a thousand times different, creating 'herring bone' or 'ghosting' effects on the picture. The television audio wouldn't be affected until the signals were nearly

It seems that some work has been done to reduce the overly American crap in this article but it's still not complete. What's with separating the USA/Canada states/provinces from the rest of the world? Are you saying that the rest of the world doesn't matter or that divisions of other countries

The reason the board made this decision was that it had been given flawed evidence by a former Federal Communications Commission engineer named Kenneth Norton. He believed that sunspots, which appear every eleven years, would cause severe disruption to the FM signal. Norton never explained why

2) During sunspot cycle maxima, ionospheric reflections often cause long distance propagation events up to the 50MHz range. This happens much less often at 100MHz. Because the FM receivers used very wideband FM and employed very good limiters, capture effect would cause the sometimes stronger

Though Loomis did get an 1872 patent, in those days a description alone was sufficient—no working model was needed. Loomis claimed his wireless telegraph used atmospheric electricity, not radio. There was never any evidence that Loomis, a dentist, ever built a working system in 20 years of

It does seem that more modern developments should be part of the article, but I agree that these, and later entries, aren't them. Probably should cover HD radio, as stations I know broadcast it even though I don't know anyone with a receiver.

I suppose so, but there is also the chicken and egg problem. People won't buy receivers until there are enough transmitters, people won't build transmitters until there are enough receivers. The frequency change also slowed things down.
