Radio amateurs
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.

...thus accelerating. In transmission, a transmitter generates an alternating current of radio frequency which is applied to an antenna. The antenna radiates the power in the current as radio waves. When the waves strike the antenna of a radio receiver, they push the electrons in the metal back and forth, inducing a tiny alternating current. The radio receiver connected to the receiving antenna detects this oscillating current and amplifies it.[citation needed] As they travel farther from the transmitting antenna, radio waves spread out so their signal strength (intensity in watts per square meter) decreases, so radio transmissions can only be received within a limited range of the transmitter, the distance depending on the transmitter power, the antenna radiation pattern, receiver sensitivity, noise level, and presence of obstructions between transmitter and receiver. An omnidirectional antenna transmits or receives radio waves in all directions, while a directional antenna or high-gain antenna transmits radio waves in a beam in a particular direction, or receives waves from only one direction.[citation needed] ...and in the air at very close to the speed of light. So the wavelength of a radio wave, the distance in meters between adjacent crests of the wave, is inversely proportional to its frequency, equal to the speed of light divided by the frequency.[citation needed] Radio waves have the ability to pass through the atmosphere in any weather, foliage, and most building materials, and by diffraction can bend around obstructions, and unlike other electromagnetic waves, they tend to be scattered rather than absorbed by objects larger than their wavelength.[citation needed] The modulation signal may be an audio signal representing sound from a microphone, a video signal representing moving images from a video camera, or a digital signal consisting of a sequence of bits representing binary data from a computer. The modulation signal is applied to a radio transmitter. In the transmitter, an electronic oscillator generates an alternating current oscillating at a radio frequency, called the carrier wave because it serves to "carry" the information through the air. The information signal is used to modulate the carrier, varying some aspect of the carrier wave, impressing the information on the carrier.[citation needed] Different radio systems use different modulation methods:
Many other types of modulation are also used. In some types, a carrier wave is not transmitted but just one or both modulation sidebands.[citation needed] The modulated carrier is amplified in the transmitter and applied to a transmitting antenna which radiates the energy as radio waves. The radio waves carry the information to the receiver location.[citation needed] This voltage is applied to the radio receiver, which amplifies the weak radio signal so it is stronger, then demodulates it, extracting the original modulation signal from the modulated carrier wave. The modulation signal is converted by a transducer back to a human-usable form: an audio signal is converted to sound waves by a loudspeaker or earphones, a video signal is converted to images by a display, while a digital signal is applied to a computer or microprocessor, which interacts with human users.[citation needed] It has a natural resonant frequency at which it oscillates. The resonant frequency of the receiver's tuned circuit is adjusted by the user to the frequency of the desired radio station; this is called "tuning". The oscillating radio signal from the desired station causes the tuned circuit to resonate, oscillate in sympathy, and it passes the signal on to the rest of the receiver. Radio signals at other frequencies are blocked by the tuned circuit and not passed on.[citation needed]
For any given signal-to-noise ratio, an amount of bandwidth can carry the same amount of information (data rate in bits per second) regardless of where in the radio frequency spectrum it is located, so bandwidth is a measure of information-carrying capacity. The bandwidth required by a radio transmission depends on the data rate of the information (modulation signal) being sent, and the spectral efficiency of the modulation method used; how much data it can transmit in each kilohertz of bandwidth. Different types of information signals carried by radio have different data rates. For example, a television (video) signal has a greater data rate than an audio signal.[citation needed] Each radio transmission occupies a portion of the total bandwidth available. Radio bandwidth is regarded as an economic good which has a monetary cost and is in increasing demand. In some parts of the radio spectrum, the right to use a frequency band or even a single radio channel is bought and sold for millions of dollars. So there is an incentive to employ technology to minimize the bandwidth used by radio services.[citation needed] In recent years there has been a transition from analog to digital radio transmission technologies. Part of the reason for this is that digital modulation can often transmit more information (a greater data rate) in a given bandwidth than analog modulation, by using data compression algorithms, which reduce redundancy in the data to be sent, and more efficient modulation. Other reasons for the transition is that digital modulation has greater noise immunity than analog, digital signal processing chips have more power and flexibility than analog circuits, and a wide variety of types of information can be transmitted using the same digital modulation.[citation needed] Because it is a fixed resource which is in demand by an increasing number of users, the radio spectrum has become increasingly congested in recent decades, and the need to use it more effectively is driving many additional radio innovations such as trunked radio systems, spread spectrum (ultra-wideband) transmission, frequency reuse, dynamic spectrum management, frequency pooling, and cognitive radio.[citation needed]
It can be seen that the bandwidth, the range of frequencies, contained in each band is not equal but increases exponentially as the frequency increases; each band contains ten times the bandwidth of the preceding band. The greater bandwidth available has motivated a continuing trend to exploit higher frequencies throughout radio's history.[citation needed]
Interference with radio transmissions can not only have a large economic cost, it can be life-threatening (for example, in the case of interference with emergency communications or air traffic control).[citation needed] Radio transmitters must be licensed by governments, under a variety of license classes depending on use, and are restricted to certain frequencies and power levels. In some classes, such as radio and television broadcasting stations, the transmitter is given a unique identifier consisting of a string of letters and numbers called a call sign, which must be used in all transmissions. The radio operator must hold a government license, such as the general radiotelephone operator license in the US, obtained by taking a test demonstrating adequate technical and legal knowledge of safe radio operation.[citation needed] Exceptions to the above rules allow the unlicensed operation by the public of low power short-range transmitters in consumer products such as cell phones, cordless phones, wireless devices, walkie-talkies, citizens band radios, wireless microphones, garage door openers, and baby monitors. In the US, these fall under Part 15 of the Federal Communications Commission (FCC) regulations. Many of these devices use the ISM bands, a series of frequency bands throughout the radio spectrum reserved for unlicensed use. Although they can be operated without a license, like all radio equipment these devices generally must be type-approved before the sale.[citation needed] Broadcasting is the one-way transmission of information from a transmitter to receivers belonging to a public audience. Since the radio waves become weaker with distance, a broadcasting station can only be received within a limited distance of its transmitter. Systems that broadcast from satellites can generally be received over an entire country or continent. Older terrestrial radio and television are paid for by commercial advertising or governments. In subscription systems like satellite television and satellite radio the customer pays a monthly fee. In these systems, the radio signal is encrypted and can only be decrypted by the receiver, which is controlled by the company and can be deactivated if the customer doesn't pay the bill.[citation needed] Broadcasting uses several parts of the radio spectrum, depending on the type of signals transmitted and the desired target audience. Longwave and medium wave signals can give reliable coverage of areas several hundred kilometers across, but have the more limited information-carrying capacity and so work best with audio signals (speech and music), and the sound quality can be degraded by radio noise from natural and artificial sources. The shortwave bands have a greater potential range but are more subject to interference by distant stations and varying atmospheric conditions that affect reception.[citation needed] In the very high frequency band, greater than 30 megahertz, the Earth's atmosphere has less of an effect on the range of signals, and line-of-sight propagation becomes the principal mode. These higher frequencies permit the great bandwidth required for television broadcasting. Since natural and artificial noise sources are less present at these frequencies, high-quality audio transmission is possible, using frequency modulation.[citation needed]
Radio broadcasting means transmission of audio (sound) to radio receivers belonging to a public audience. Analog audio is the earliest form of radio broadcast. AM broadcasting began around 1920. FM broadcasting was introduced in the late 1930s with improved fidelity. A broadcast radio receiver is called a radio. Most radios can receive both AM and FM and are called AM/FM receivers.[citation needed]
DAB has the potential to provide higher quality sound than FM (although many stations do not choose to transmit at such high quality), has greater immunity to radio noise and interference, makes better use of scarce radio spectrum bandwidth and provides advanced user features such as electronic program guides. Its disadvantage is that it is incompatible with previous radios so that a new DAB receiver must be purchased. Most countries plan an eventual switchover from FM to DAB. The United States and Canada have chosen not to implement DAB.[citation needed]
Television broadcasting is the transmission of moving images by radio, which consist of sequences of still images, which are displayed on a screen on a television receiver (a "television" or TV) along with a synchronized audio (sound) channel. Television (video) signals occupy a wider bandwidth than broadcast radio (audio) signals. Analog television, the original television technology, required 6 MHz, so the television frequency bands are divided into 6 MHz channels, now called "RF channels". The current television standard, introduced beginning in 2006, is a digital format called high-definition television (HDTV), which transmits pictures at higher resolution, typically 1080 pixels high by 1920 pixels wide, at a rate of 25 or 30 frames per second. Digital television (DTV) transmission systems, which replaced older analog television in a transition beginning in 2006, use image compression and high-efficiency digital modulation such as OFDM and 8VSB to transmit HDTV video within a smaller bandwidth than the old analog channels, saving scarce radio spectrum space. Therefore, each of the 6 MHz analog RF channels now carries up to 7 DTV channels – these are called "virtual channels". Digital television receivers have different behavior in the presence of poor reception or noise than analog television, called the "digital cliff" effect. Unlike analog television, in which increasingly poor reception causes the picture quality to gradually degrade, in digital television picture quality is not affected by poor reception until, at a certain point, the receiver stops working and the screen goes black.[citation needed]
Government standard frequency and time signal services operate time radio stations which continuously broadcast extremely accurate time signals produced by atomic clocks, as a reference to synchronize other clocks. Examples are BPC, DCF77, JJY, MSF, RTZ, TDF, WWV, and YVTO. One use is in radio clocks and watches, which include an automated receiver that periodically (usually weekly) receives and decodes the time signal and resets the watch's internal quartz clock to the correct time, thus allowing a small watch or desk clock to have the same accuracy as an atomic clock. Government time stations are declining in number because GPS satellites and the Internet Network Time Protocol (NTP) provide equally accurate time standards.[citation needed]
A two-way radio is an audio transceiver, a receiver and transmitter in the same device, used for bidirectional person-to-person voice communication with other users with similar radios. An older term for this mode of communication is radiotelephony. The radio link may be half-duplex, as in a walkie-talkie, using a single radio channel in which only one radio can transmit at a time, so different users take turns talking, pressing a "push to talk" button on their radio which switches off the receiver and switches on the transmitter. Or the radio link may be full duplex, a bidirectional link using two radio channels so both people can talk at the same time, as in a cell phone.[citation needed] All the cell phones in a cell communicate with this antenna on separate frequency channels, assigned from a common pool of frequencies.The purpose of cellular organization is to conserve radio bandwidth by frequency reuse. Low power transmitters are used so the radio waves used in a cell do not travel far beyond the cell, allowing the same frequencies to be reused in geographically separated cells. When a user carrying a cellphone crosses from one cell to another, his phone is automatically "handed off" seamlessly to the new antenna and assigned new frequencies. Cellphones have a highly automated full duplex digital transceiver using OFDM modulation using two digital radio channels, each carrying one direction of the bidirectional conversation, as well as a control channel that handles dialing calls and "handing off" the phone to another cell tower. Older 2G, 3G, and 4G networks use frequencies in the UHF and low microwave range, between 700 MHz and 3 GHz. The cell phone transmitter adjusts its power output to use the minimum power necessary to communicate with the cell tower; 0.6 W when near the tower, up to 3 W when farther away. Cell tower channel transmitter power is 50 W. Current generation phones, called smartphones, have many functions besides making telephone calls, and therefore have several other radio transmitters and receivers that connect them with other networks: usually a Wi-Fi modem, a Bluetooth modem, and a GPS receiver.
These systems have a fairly limited range, usually 3 to 20 miles (4.8 to 32 km) depending on terrain. Repeaters installed on tall buildings, hills, or mountain peaks are often used to increase the range when it is desired to cover a larger area than line-of-sight. Examples of land mobile systems are CB, FRS, GMRS, and MURS. Modern digital systems, called trunked radio systems, have a digital channel management system using a control channel that automatically assigns frequency channels to user groups.
One way, unidirectional radio transmission is called simplex.
This is radio communication between a spacecraft and an Earth-based ground station, or another spacecraft. Communication with spacecraft involves the longest transmission distances of any radio links, up to billions of kilometers for interplanetary spacecraft. In order to receive the weak signals from distant spacecraft, satellite ground stations use large parabolic "dish" antennas up to 25 metres (82 ft) in diameter and extremely sensitive receivers. High frequencies in the microwave band are used, since microwaves pass through the ionosphere without refraction, and at microwave frequencies the high-gain antennas needed to focus the radio energy into a narrow beam pointed at the receiver are small and take up a minimum of space in a satellite. Portions of the UHF, L, C, S, ku and ka band are allocated for space communication. A radio link that transmits data from the Earth's surface to a spacecraft is called an uplink, while a link that transmits data from the spacecraft to the ground is called a downlink.[citation needed] Most are in geostationary orbit 22,200 miles (35,700 km) above the equator, so that the satellite appears stationary at the same point in the sky, so the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track it. In a satellite ground station a microwave transmitter and large satellite dish antenna transmit a microwave uplink beam to the satellite. The uplink signal carries many channels of telecommunications traffic, such as long-distance telephone calls, television programs, and internet signals, using a technique called frequency-division multiplexing (FDM). On the satellite, a transponder receives the signal, translates it to a different downlink frequency to avoid interfering with the uplink signal, and retransmits it down to another ground station, which may be widely separated from the first. There the downlink signal is demodulated and the telecommunications traffic it carries is sent to its local destinations through landlines. Communication satellites typically have several dozen transponders on different frequencies, which are leased by different users.
Radar is a radiolocation method used to locate and track aircraft, spacecraft, missiles, ships, vehicles, and also to map weather patterns and terrain. A radar set consists of a transmitter and receiver. The transmitter emits a narrow beam of radio waves which is swept around the surrounding space. When the beam strikes a target object, radio waves are reflected back to the receiver. The direction of the beam reveals the object's location. Since radio waves travel at a constant speed close to the speed of light, by measuring the brief time delay between the outgoing pulse and the received "echo", the range to the target can be calculated. The targets are often displayed graphically on a map display called a radar screen. Doppler radar can measure a moving object's velocity, by measuring the change in frequency of the return radio waves due to the Doppler effect.[citation needed] Radar sets mainly use high frequencies in the microwave bands, because these frequencies create strong reflections from objects the size of vehicles and can be focused into narrow beams with compact antennas. Parabolic (dish) antennas are widely used. In most radars the transmitting antenna also serves as the receiving antenna; this is called a monostatic radar. A radar which uses separate transmitting and receiving antennas is called a bistatic radar.[citation needed]
Radiolocation is a generic term covering a variety of techniques that use radio waves to find the location of objects, or for navigation
Radio remote control is the use of electronic control signals sent by radio waves from a transmitter to control the actions of a device at a remote location. Remote control systems may also include telemetry channels in the other direction, used to transmit real-time information of the state of the device back to the control station. Unmanned spacecraft are an example of remote controlled machines, controlled by commands transmitted by satellite ground stations. Most handheld remote controls used to control consumer electronics products like televisions or DVD players actually operate by infrared light rather than radio waves, so are not examples of radio remote control. A security concern with remote control systems is spoofing, in which an unauthorized person transmits an imitation of the control signal to take control of the device. Examples of radio remote control:
During wartime, militaries use jamming to interfere with enemies' tactical radio communication. Since radio waves can pass beyond national borders, some totalitarian countries which practice censorship use jamming to prevent their citizens from listening to broadcasts from radio stations in other countries. Jamming is usually accomplished by a powerful transmitter which generates noise on the same frequency as the target transmitter.[citation needed]
However, this invention would not be widely adopted.[citation needed] Following Heinrich Hertz's discovery of the existence of radio waves in 1886, a variety of terms were initially used for this radiation, including "Hertzian waves", "electric waves", and "ether waves". The first practical radio communications systems, developed by Guglielmo Marconi in 1894–5, transmitted telegraph signals by radio waves, so radio communication was first called "wireless telegraphy". Up until about 1910 the term "wireless telegraphy" also included a variety of other experimental systems for transmitting telegraph signals without wires, including electrostatic induction, electromagnetic induction and aquatic and earth conduction, so there was a need for a more precise term referring exclusively to electromagnetic radiation.[citation needed] The French text of both the 1903 and 1906 Berlin Radiotelegraphic Conventions includes the phrases "radiotélégraphique" and "radiotélégrammes".[citation needed] This practice was universally adopted, and the word "radio" introduced internationally, by the 1906 Berlin Radiotelegraphic Convention, which included a Service Regulation specifying that "Radiotelegrams shall show in the preamble that the service is 'Radio'".[citation needed] British Commonwealth countries continued to commonly use the term "wireless" until the mid-20th century, though the magazine of the British Broadcasting Corporation in the UK has been called Radio Times since its founding in the early 1920s.[citation needed] The term "wireless" eventually gained renewed popularity as a more general term for devices communicating using electromagnetic radiation, either radio waves or light, due to the rapid growth of short-range computer networking, e.g., wireless local area networks Wi-Fi, and Bluetooth, as well as cell phones, to distinguish these uses from traditional "radio" communication, such as broadcasting.[citation needed] |
Discussion
- I think this was unwise. All this stuff is brick standard and shouldn't be controversial. Just because someone has sprinkled "cn" tags throughout doesn't mean the material isn't accurate. It's tiresome in the extreme to footnote every single sentence, when any standard reference works on the subject will give pretty much the same uncontroversial facts. --Wtshymanski (talk) 22:13, 14 August 2022 (UTC)
- I am opposed to this process for dealing with uncontroversial uncited material and it it looks like we have two other experienced editors similarly opposed which, as I see it, makes a consensus. I've reverted your deletion of material from the article. ~Kvng (talk) 14:35, 18 August 2022 (UTC)
I agree that long sections of the article shouldn't be totally uncited, however Wtshymanski is correct that this stuff is uncontroversial standard basics that I think he's done a good job of summarizing. Any decent textbook will adequately cover these basics:
- Basic Radio Principles and Technology - Elsevier Science
- The Electronics of Radio - Cambridge University Press
- Radio Systems Engineering - Cambridge University Press
- Radio-Electronic Transmission Fundamentals - SciTech Publishing
- Analog Electronics, Analog Circuitry Explained - Elsevier Science
Any of these could be cited, either as general references or specific inline citations. - LuckyLouie (talk) 13:58, 15 August 2022 (UTC)
- It doesn't matter if it uncontroversial. Inline citations need to accompany the material. Nightscream (talk) 16:39, 15 August 2022 (UTC)
- I've found at least one instance of a tag indicating a citation was needed for material that was explicitly cited [1]. You might want to check the rest of your tags. - LuckyLouie (talk) 17:56, 15 August 2022 (UTC)
- Nobody's perfect, but one mistake does not justify violating WP:V, et al. by restoring entire swaths of uncited material, and as a veteran editor with over 24,000 edits under your belt, you should know better. Do it again, and I'll contact an admin about your policy violations. Please do not make that necessary. If you want to improve the article, then add citations to the material in question before restoring it. For my part, I apologize if I incorrectly moved a cited passage here from the article. Nightscream (talk) 14:44, 18 August 2022 (UTC)
- Nightscream has reverted and I won't start or continue an edit war. Here's some previous discussion of Nightscream's approach. If we don't have a consensus that this is the right approach, I encourage someone else (Wtshymanski, LuckyLouie, Johnuniq) to restore the deleted material and we can deal with the identified issues in place. ~Kvng (talk) 14:54, 18 August 2022 (UTC)
- I haven't yet reverted anything in the article, I think Nightscream confused me with 86.181.0.154 or perhaps KVng. Yes, we all believe in WP:V as a core policy. But my personal view is that articles lacking inline citations that have been reviewed as generally accurate by editors familiar with the topic are best served with unreferenced section templates rather than inline tags for each sentence. I've listed a number of general references above. These can be applied as WP:GENREF until someone undertakes the laborious job of vetting each one as appropriate to a particular section of text. - LuckyLouie (talk) 15:32, 18 August 2022 (UTC)

Nightscream (talk) 14:44, 18 August 2022 (UTC)
- User:86.181.0.154 appears to be another and separate editor who is opposed to Nightscream's process. There definitely is a consensus against this and @LuckyLouie has here proposed an alternative that I support. ~Kvng (talk) 16:21, 18 August 2022 (UTC)
- There is no "consensus" on this. Two or three people violating WP:V/WP:NOR who are participating or are mentioned in a talk page discussion that hasn't been opened to the wider editing community is not a consensus. But if you want me to invite a larger numbe of editors and admins to this discussion to see if they agree with you, or if they'll tell you as I have that you are violating policy, then by all means, let me know.
- "Reviewed as generally accurate by editors familiar with the topic" is simply one more subjective standard offered by those who try to rationalize ignoring WP:V, and like all the others I've heard, it is both vague, and stands in contrast with core Wikipedia policies that make it clear that editors' personal knowledge — which precisely what you are describing with this phrase — is not a valid basis for inclusion. Which editors are these? Who has "reviewed"? Where? When? Can you link me to these "reviews"? The only type of "review" I'm familiar with on Wikipedia is when an article is nominated for FA or GA, and in those cases, citations are always a fundamental criterion of that process. Inclusion of material on Wikipedia is based on sources, and not what editors' assert, which is original research, and is strictly prohibited. Do you dispute this? Yes or no? Please let me know.
- Unreferenced tags are an appropriate way to alert editors that material needs citations. But this does not address what to do when material has remained uncited for a persistent length of time. Nightscream (talk) 17:35, 18 August 2022 (UTC)
- I gather your position is that it doesn't matter how the editors of this page want to work on improving it; What matters is that it be done according to policy and that's the way you're doing it and the rest of us are violating policy.
- I will just remind you that, creation of policy and interpretation of it is done through consensus. Consensus is more important than policy. To impose your interpretation of policy aggressively like this by tagging then removing uncontroversial content is just disruptive. ~Kvng (talk) 18:49, 18 August 2022 (UTC)
- Nightscream, I used the word "review" in an informal sense to refer to the efforts of the article's major contributors like User:Chetvorno and User:Wtshymanski and I also prefaced my suggestions as "my personal view" and not as policy -- but I think you know that. So I'll just back off and let this play out. - LuckyLouie (talk) 19:16, 18 August 2022 (UTC)
- Main offender here. I wrote most of the article, and didn't include sources. I'll work on sourcing it, but it's going to be a while. --ChetvornoTALK 00:18, 19 August 2022 (UTC)

Kvng: "Consensus is more important than policy." No, consensus and policy are not mututally exclusive. Rather, Wikipedia's policies and guidelines are intended to reflect the consensus of the community. We know this because it explicitly says this here. That is not "my position" nor an "interpretation" of it. It's the explicitly stated position of the editing community here. By contrast, where is it indicated that one is "more important than" the other? For that matter, how do you personallly know what "consensus" is, if not by citation of policy? What roles do you think the site's policies and guidelines serve, if not to govern editing habits? Do you believe that a handful of editors who simply don't feel like adhering to policy can ignore it by getting together and saying "consensus" when an editor who seeks to uphold policy confronts them? Is that what you believe? If you can answer these questions, please do so. Tell me where or how you arrived at the conclusion that consensus is more important than policy. Is the above-liked passage that says that one reflects the other wrong? Or are both statements not incompatible? I want to know your thoughts on this.
Kvng: "I used the word "review" in an informal sense to refer to the efforts of the article's major contributors like User:Chetvorno and User:Wtshymanski..." It doesn't matter. Inclusion of material not determined by "reviewed as generally accurate by editors familiar with the topic," because that's called original research, and is strictly prohibited. You say that that this was a personal viewpoint of yours and not policy. I agree. And that's why it's an irrelevant standard here. We do not include material just because major contributors reviewed the material as accurate, because the standard for inclusion on Wikipedia is not accuracy. It's verifiability. This argument is even more questionable when one of those contributors you cite, Chetvorno, admitted that he wrote most of the article without sources, a clear violation of the consensus of the community described at WP:V and WP:NOR, yet you hold him up like some kind of Good Housekeeping seal of approval. We include material supported by citations, and not that which is based on personal expertise or knowledge. That is not "my position" nor an "interpretation" of policy, it is policy. If you can refute this, then do so. Tell me that WP:NOR does not expressly forbid us from adding uncited material on the basis of personal knowledge. Tell me that what Chetvorno did -- and what you continue to promote -- is precisely that. If you can explain how what I just said is wrong, wihtout spin, lies, rhetorical tricks, logical fallacies, or non-sequiturs, then please, do so. Nightscream (talk) 16:37, 23 August 2022 (UTC)
Edit warring
Nightscream has reversed 3 attempts to restore this material by 3 different editors (Wtshymanski, 86.181.0.154, myself) over 5 days. 86.181.0.154 recently posted a warning. I have seconded that by reporting it. ~Kvng (talk) 14:18, 19 August 2022 (UTC)
- I support the 3 editors restoring the material. Nightscream’s drastic cuts cross the line into WP:POINT.--ChetvornoTALK 15:07, 19 August 2022 (UTC)
- My experience suggests that as only three reverts have been made (so far), that this is unlikely to fly (which is why I didn't raise it - though I would have on the forth revert). However there are other articles where this behaviour is now going on such as Phonograph record and Typecasting. I was initially also going to add Sean Phillips, but this is probably overruled by WP:BLP which specifically prohibits uncited material from such biographies. I think WP:ANI might have been a better venue, but that's just my opinion which is worth exactly what you paid for it. 86.181.0.154 (talk) 16:49, 19 August 2022 (UTC)
- I would have also reverted Nightscream's drastic cuts and, as an interim measure, applied the combination of section templates and general references I described here, but I felt that would only exacerbate Nightscream's edit warring. - LuckyLouie (talk) 17:01, 19 August 2022 (UTC)
- Nightscream has reverted three editors in a fight for these changes which are not supported by any of the editors who have participated in the discussion here. Behavior doesn't have to meet WP:3RR to be considered warring. We'll see. ~Kvng (talk) 18:28, 19 August 2022 (UTC)
Just for the record, Nightscream is still at it. Here and here. As I pointed out to Nightscream on my talk page, the last time I saw this at Alternator in 2018, the two editors removing the uncited material (though uncontentious by consensus) were indefinitely blocked for disruptive editing (and the material is still there - uncited as ever). This being the case, there appears to be the application of double standards. 86.181.0.154 (talk) 14:08, 21 August 2022 (UTC)
- Yeah, you tried citing that anecdote on your talk page too, and when I questioned you about it, because I was skeptical that it went down as you described, you refused to provide diffs, or even answer it. During that discussion, you twice spoke derisively of editors like me who “quote all manner of policies” for removing uncited material (without explaining how the citations of those policies was wrong), and claimed on the Alternator article, two editors who quoted the same policies when deleting uncited material were indefinitely blocked for disruptive editing, and the uncited material remains in the article. I asked you what was wrong with their citation policies. I asked you if those two editors' activities were deemed disruptive solely because they removed material, or for other reasons instead of/in addition to this, like edit warring. The reason I ask is because I had had discussions elsewhere that indicated that such blocks were unlikely for what I was doing. On Jimbo Wales' tp, for example, one editor told Johnuniq, "Tagging and subsequently removing uncited material is not a problem. Any block you placed (as you threatened Nightscream with) on that rationale would almost certainly be overturned and result in you being asked to justify yourself in front of ARBCOM for abuse of admin tools." Then at the recent discussion at the Village Pump, where it was indicated that this notion of yours did not reflect consensus, as one editor responded to Johnuniq's complaint of my moving to the talk page "good material" by asking him point-blank, "Please explain how any material can be described as 'good' if it is not verified," while another stated that he did "see evidence that the OP [Johnuniq] is a problematic editor." Offhand, I could not find any trace of this episode you described in the Alternator article's edit history or talk page. If there were editors who were blocked, then I'm guessing it was because they committed other actions, like edit-warring, or because unlike myself, they deleted material, rather than move it to the talk page, complete with a diff showing where it was in the article, and made efforts to source some of it as I have.
- I flat-out asked you about this, asking you if those editors actually deleted that material, moved it to the talk page to spur others to source it, and to do some of that sourcing themselves. But you refused to answer, possibly because you misrepresented this conflict, deliberately omitting key details, and when I called you on your bluff, you knew you couldn't provide diffs that would prove me right. Indeed, you continue to refer to my moves as "deletions", even after I suggested to you that omitting those key details by simply calling my practices "deletion" may cause a reader to incorrectly understand that I've absolutely removed information entirely from the article without any means or avenue for its restoration, which is not accurate or honest. You continued to refuse to address these counterarguments, saying, "I do not propose to spend my time arguing the point", while simultaneously criticizing me for not adhering to Bold-Revert-Discuss—even though you're the one refusing to discuss my counterarguments.
- Some of you like to cite "consensus", as if a handful of editors on a talk page constitutes a consensus that allows you to violate policy, and that those who oppose you falsify this by presenting arguments or reasoning that conclusively disagrees with you, that you can just ignore those arguments if there's enough of you on that talk page, rather than engage with those arguments. This is not true, and it's not honest. Bear in mind also that I have not asked others who I know agree with me to join me here. If they did, would you still have "consensus"?) The consensus of the editing community (not just some editors on one talk page) is reflected in its policies, and part of interpreting policy is noting what it says on the site's various policy and guideline pages. You can't do an end-run around site-wide policy simply by having several people agree to do so on a single article's talk page. You have to show how your stated position and arguments is in line with those policies.
- Over on the Isaac Hempstead Wright article, I had to remove uncited additions of that actor's date of birth several times ([2][3][4][5][6][7]). Are you going to argue that those editors constituted a "consensus", and that I was edit warring because there were more of them than I?
- Since WP:NOR makes it clear that material cannot be added on the basis of editors' personal knowledge or expertise, claiming that uncited material cannot be moved to the talk page because editors claim it is "potentially good", violates this policy. If you can show why this is wrong, then please explain how.
- Please take the time to explain why the underlying reasoning in my position is flawed, which thing I've said is untrue. Don't just argue the same position over and over because you don't want to change it. If you can argue that adding and keeping large swaths of uncited material/original research to articles, which Chetvorno admitted they did in this article, then do so. Otherwise, stop complaining that I'm not engaging in "discussion", as more than one of you have mendaciously stated. If you continue to do this, your actions will simply be tacitly confirmed as serial policy violations, as it was not only determined at ANI that my moving of uncited material and undoing your reverts was not a violation, but that the conduct that in which Kvng engaged in order to get his way was deemed inappropriate, which it clearly was.
- I've held off on doing more moves of articles that have passed the one-month mark in the past few days, so you can respond. But if you continue to employ the "indirect" method of responding, then I'm not going to bother continuing to do so. Please falsify my arguments, or acknowledge that your actions violate policy, and resolve to do the work of sourcing that material as you restore it to articles.

- +1, Nightscream please try again ~Kvng (talk) 17:23, 25 August 2022 (UTC)
- If you are indicating that you won't read something that is the equivalent of a two-page Word document, which is needed to debunk the numerous logical fallacies, lies, and non-sequiturs that multiple serial policy violators have promulgated on multiple discussion pages recently, which cannot be done in the span of a soundbite, then the problem isn't the length of my post. It's that in addition to thinking policies and guidelines don't apply to you, that you're too either too lazy or illiterate, or know that you can't falsify my statements. Uttering a ridiculous canard like "Consensus is more important than policy" takes little time, but explaining why it's bunk -- along with addressing all the other various examples of corruption you've collectively exhibited -- takes longer. It's probably why, as it's been observed, that lies travel faster than truth.
- Falsify what I've said. Or stop whining to me that I won't "discuss" things with you. Other members of the community have already called you on your practices and your threats are unacceptable.

- Nightscream, long emotional screeds arguing how you are right and everyone else is wrong and a liar are counterproductive. How about this as an alternative to leaving out huge swaths of the article until someone undertakes the laborious job of fitting each general reference to a particular section of text. Would you agree to:
- Replacing inline ‘citation needed’ tags after each sentence with unreferenced section templates in each section.
- Adding WP:GENREF (I listed here.

- Agree with LuckyLouie. This ham-fisted mass deletion/WP:POINTY has (gone) far enough. Should be WP:BRDed and we can start from there with the suggested templates. Fountains of Bryn Mawr (talk) 20:10, 25 August 2022 (UTC)
- @Fountains of Bryn Mawr, @LuckyLouie, please, do revert these changes if you want to discuss them further before they become permanent. Three of us have already tried, but the more the merrier. ~Kvng (talk) 17:54, 27 August 2022 (UTC)

- What is being overlooked here is that Wikipedia as a project is a collaborative venture not in the WP:OWNERship of one individual. Yes, there are policies in place to stop disruptive editing, but part of the point of collaboration is that policy can be, to a greater or lesser extent, overruled where there is clear consensus on the article talk page to do so. The gutting of this (and other) articles because content, though well established as correct, not being fully referenced is a case in point. There is a clear near unanimous consensus above that the unreferenced material should be restored as it is accepted, by that consensus, that it is correct without further proof.
- I believe it would be worth starting a 'Request for Comment' on this issue. As an IP, I cannot initiate one, but am willing to participate should someone else choose to do so. 86.181.0.154 (talk) 13:20, 27 August 2022 (UTC)
- An RFC here may or may not stick. It certainly would not resolve the general issue of whether (re)moving uncontroversial uncited material is disruptive. I'm not sure what is the best venue to try and work this out. It is not my idea of fun and I don't expect, given Wikipedia's general slide towards deletionism, I'm going to be satisfied with the outcome. ~Kvng (talk) 15:09, 27 August 2022 (UTC)

I have gone ahead and partially reverted the article (to as edited by Kvng at 14:36, 18 August 2022) per WP:BRD, LuckyLouie, and no further comment above. Most of the content is WP:LIST and does not need citation per say and is notable and already cited (at its parent article). Overall gutting articles, breaking syntax, and making them generally unreadable seems to be and exercise in WP:POINTY. Fountains of Bryn Mawr (talk) 19:11, 27 August 2022 (UTC)
- Thanks, also would have been very difficult to work on sourcing with text split between article and Talk page. --ChetvornoTALK 23:59, 28 August 2022 (UTC)
- "The bottom line here is that Nightscream alone is right and everybody else is wrong."
- Wrong. The point is that the consensus of the editing community is reflected in Wikipedia's policies (as it states right here), but you seem to think that they are wrong, and that you can get away with ignoring those policies is not by overturning them, but by assembling several editors on one talk page, and that somehow constitutes the "consensus". It does not, and I explained above how this idea is bunk. Your reaction is to refuse to answer, and employ all manner of excuses for not doing so, because you can't admit that you can't falsify any of my counterarguments.
- I have alerted administrators to your continued campaign to ignore Wikipedia's core policies.
- And btw, bear in mind that when Kvng attempted to report me at ANI my talk page moves and reverts were determined to be "no violation". Nightscream (talk) 01:11, 29 August 2022 (UTC)
- You have mis-stated the facts - the characteristic resort of someone who is firmly in the wrong. Kvng reported you to WP:ANEW - a completely different venue from WP:ANI handling completely different issues. As I predicted above, there was no violation but only because you had made only three reverts to this article. Had you made a fourth, that would have crossed a line and you may well have been blocked. The issues that you claim are not included in the exceptions to the 3RR rule (WP:3RRNO), which should tell you something.
- Oh, and a number of editors who agree with each other is a consensus, even if you don't like what they are agreeing to (this is a collaborative project whether you like it or not). And what is more, it seems another administrator is weighing in against you on Daniel Case's talk page underlining my point in the previous paragraph and adding to the consensus. It would be wise of you at this point to drop the stick and back slowly away from the carcass. 86.181.0.154 (talk) 12:21, 29 August 2022 (UTC)
- This pattern continues. I've created a list of articles I know are affected. Please add any others you may be aware of. ~Kvng (talk) 03:45, 30 August 2022 (UTC)

- It's also worth pointing out that Nightscream's continued assertion that both you and Chetvorno are a "policy violator" or "serial policy violator" is a sustained and repeated personal attack. He has also attacked Johnuniq by stating that "Johnuniq is continuing his anti-WP:V vendetta". Contributors are required to comment on the article or its content but are not permitted to attack other contributors. Nightscream proposed WP:ANI above. considering the traction that this is getting here and elsewhere, it might be a good idea.
- Oh, and I have expanded your list somewhat. Or I though I had until a huge edit conflict clobbered it. Seems to have swept up my offerings anyway. 86.181.0.154 (talk) 16:40, 30 August 2022 (UTC)
- Sorry about that. Matthiaspaul added a bunch and then I resorted the lists. The browser back button is surprisingly useful during edit conflicts. ~Kvng (talk) 19:38, 30 August 2022 (UTC)

Nightscream has been repeatedly [8], [9] removing text from the article again, while several editors are working on citing. Having the article text split with some on the Talk page makes it hard to do the sourcing he claims to want. --ChetvornoTALK 01:38, 4 September 2022 (UTC)
- Unfortunately the diffs are hard to follow due to fiddling with spaces and reference formats. Nevertheless I would recommend taking the trouble to restore just a couple of items that were removed with an edit summary indicating that they are going to be worked on in the next week. Then they need to be fixed with citations in that week. That is, don't restore everything at the moment. Johnuniq (talk) 02:42, 4 September 2022 (UTC)
Nightscream reported to WP:ANEW (again), this time for nine reverts of which the last four are within ten hours violating the three revert rule. So who is the policy violator now? 86.181.0.154 (talk) 13:12, 4 September 2022 (UTC)
- Regarding Nightscream's claim that citations MUST be supplied, the guideline WP:V says only that information in articles "must be verifiable." Widely known facts and basic elementary statements about the topic will always be verifiable without a specific citation. Any and every textbook about radio would be able to verify the facts.
- Only disputed facts must be verified with a citation. The previous tagging action is tendentious: going around adding "citation needed" tags to text describing basic topic knowledge. Binksternet (talk) 18:16, 4 September 2022 (UTC)
- There is no such passage at WP:V or anywhere else that states that only disputed facts must be verified with citations. At WP:BURDEN it states: "All content must be verifiable. The burden to demonstrate verifiability lies with the editor who adds or restores material, and it is satisfied by providing an inline citation to a reliable source that directly supports the contribution." Nightscream (talk) 13:27, 6 September 2022 (UTC)
- But it is the case that WP:V does not require every sentence to be inline cited. Now it's possible to force inline citing on everything by challenging everything, but it is not necessary to take such action. That imo is gaming the system and deleting stuff wholesale as a result is a highly disruptive thing to do. A more collegial approach would be to first attempt to find citations yourself in the spirit of WP:BEFORE.
- WP:V states When tagging or removing material for lacking an inline citation, please state your concern that it may not be possible to find a published reliable source, and the material therefore may not be verifiable. That is, tagging or removal of material should be a result of a real concern over its accuracy, not simply because it is uncited. Further, in a footnote, Some editors object to others making chronic, frequent, and large-scale deletions of unsourced information, especially if unaccompanied by other efforts to improve the material. You might want to consider whether that policy is talking to you. SpinningSpark 09:07, 7 September 2022 (UTC)
- Precisely. WP:V only requires such material to be verifiable but not necessarily inline referenced if it is generally accepted as true and the discussion here shows universal agreement that it is factual. The stuff that Nightscream has deleted is easily verifiable.
- There is no such passage at WP:V or anywhere else that states that only disputed facts must be verified with citations. At WP:BURDEN it states: "All content must be verifiable. The burden to demonstrate verifiability lies with the editor who adds or restores material, and it is satisfied by providing an inline citation to a reliable source that directly supports the contribution." Nightscream (talk) 13:27, 6 September 2022 (UTC)
- It is interesting to note that Nightscream wholesale deletes it, but makes zero attempt to reference it himself but expects everyone else to do the spade work. With that and his repeated threats that he will get anyone who disagrees with him on his talk page blocked is the typical behaviour of a bully. My analysis of the way Nightscream interacts with other users here, and elsewhere, leaves me with a very real impression that we are dealing with a child or at best a very immature adult - but definitely someone who has problems interacting with others. Whatever, he still has no intention of cooperating with others at all, let alone to build an encyclopaedia . 86.181.0.154 (talk) 10:19, 8 September 2022 (UTC)
List?
Large parts of this article seem to be in list form. Should it be converted more towards prose? Fountains of Bryn Mawr (talk) 19:36, 27 August 2022 (UTC)
- You and I talked about this in this thread. My feeling is that the number of applications and subindustries within radio justified a WP:SUMMARYSTYLE list structure in the "Applications" section for clarity. When you get 3-4 levels deep, the Wikipedia section headings don't do a good job of visually distinguishing what sections are inside other sections. But other editors on this page have disagreed. --ChetvornoTALK 21:12, 27 August 2022 (UTC)
Sourcing by section
I agree with others that it's preferable to work on sourcing the live article text. If the content was obvious nonsense, fringe, erroneous, etc. I would not contest the mass deletions. But in this case, the content is quite uncontroversial and largely accurate - it just needs sources added. I started to add citations to the "Radio communication" section the other day, but was thwarted due to edit conflicts by others working on the same section. I suggest we let each other know which sections we're working on to avoid edit conflicts. - LuckyLouie (talk) 13:57, 29 August 2022 (UTC)
- While editing, you can always put the {{in use}} template at the top of the article, but please remember to remove it when you are done. If working on a section, use its little brother {{in use|section}}.
- If you are performing a series of edits, you can put {{Under construction}} at the top of the article as a flag to advise others that work is being actively undertaken. 86.181.0.154 (talk) 14:26, 29 August 2022 (UTC)
- Good idea, wilco --ChetvornoTALK 14:39, 29 August 2022 (UTC)
- OK, good suggestion. - LuckyLouie (talk) 15:11, 29 August 2022 (UTC)
I was able to make some progress adding sources, but only at the rate of a few paragraphs per day. I could not go any faster, most will agree this type of work takes time. But now with these mass deletions of uncited text from the article, it's needlessly made more difficult to add needed cites while keeping track of duplicate citations. I'm certainly not a "serial policy violator" and it's sad to see other editors disparaged this way. Sorry, but I won't be working on the article again until the situation is resolved and the disruption ends. - LuckyLouie (talk) 17:23, 3 September 2022 (UTC)
- Restored it, hopefully it stays that way. It really is disruption. Fountains of Bryn Mawr (talk) 21:17, 3 September 2022 (UTC)
- If the edit war chaos has subsided, I'll be putting more time into sourcing, working from the bottom up. Unfortunately I can't complete it all in one sitting, so I will have to do it over a series of days. - LuckyLouie (talk) 20:53, 9 September 2022 (UTC)
