and community, at sign-on, sign-off, and at the top of every hour of operation. Other current requirements include providing a local telephone number in the community's calling area (or else a toll-free number). The former requirement to (in most cases) maintain an official main studio within 25 miles of the community's geographic center was discontinued in December 2017 when the regulation was amended.
Policy and regulatory issues
Nominal main studio requirements
The requirement that a station maintain a main studio within a station's primary coverage area or within a maximum distance of the community of license originated in an era in which stations were legally required to generate local content and the majority of a station's local, non-network programming was expected to originate in one central studio location. In this context, the view of broadcast regulators held that an expedient way to ensure that content broadcast reflected the needs of a local community was to allocate local broadcast stations and studios to each individual city.
The nominal main studio requirement has become less relevant with the introduction of
videotape

ization, and the elimination of requirements (in 1987 for most classes of US broadcast stations) that broadcasters originate any minimum amount of local content.
While the main studio concept nominally remains in US broadcast regulations, and certain administrative requirements (such as the local employment of a manager and the equivalent of at least one other full-time staff member, as well as the maintenance of a public inspection file) are still applied, removal of the requirement that stations originate local content greatly weakens the significance of maintaining a local main studio.

has greatly weakened the role and importance of manual control by staff at the nominal local station studio facilities.
Exceptions to these rules have been made by regulators, primarily on a case-by-case basis, to deal with "satellite stations": transmitters which are licensed to comply with the technical requirements of
full service broadcast facilities and have their own independent

s and communities of license but are used simply as full-power
broadcast translators to rebroadcast another station. These are most often non-commercial educational stations or stations serving thinly populated areas which otherwise would be too small to support an independent local full-service broadcaster.
Political considerations
The requirement that a full-service station maintain local presence in its community of license has been used by proponents of
localism and
community broadcasting as a means to oppose the construction and use of local stations as mere rebroadcasters or satellite-fed translators of distant stations. Without specific requirements for service to the local community of license, stations could be constructed in large number by out-of-region broadcasters who feed transmitters via
satellite

and offer no local content.
There also has been a de facto preference by regulators to encourage the assignment of broadcast licenses to smaller cities which otherwise would have no local voice, instead of allowing all broadcast activity to be concentrated in large metropolitan areas already served by many existing broadcasters.
When dealing with multiple competing US radio station applications, current FM allotment priorities are: (1) first full-time aural service; (2) second full-time aural service; (3) first local aural transmission service; and (4) Other public interest matters.
Similar criteria were extended to competing applicants for non-commercial stations by US legislation passed in 2000.
Suburban community problem
Any policy favoring applicants for communities not already served by an existing station has had the unintended effect of encouraging applicants to merely list a small suburb of a large city, claiming to be the "first station in the community" even though the larger city is well served by many existing stations. "The Suburban Community Problem" was recognized in FCC policy as early as 1965. "Stations in metropolitan areas often tend to seek out national and regional advertisers and to identify themselves with the entire metropolitan area rather than with the particular needs of their specified communities," according to an FCC policy statement of the era. In order "to discourage applicants for smaller communities who would be merely substandard stations for neighboring, larger communities," the FCC established the so-called "Suburban Community presumption" which required applicants for AM stations in such markets to demonstrate that they had ascertained the unmet programming needs of the specific communities and were prepared to satisfy those needs.
By 1969, the same issues had spread to FM licensing; instead of building transmitters in the community to nominally be served, applicants would often seek to locate the tower site at least halfway to the next major city. In one such precedent case (the Berwick Doctrine), the FCC required a hearing before Berwick, a prospective broadcaster, could locate transmitters midway between
Pittston, Pennsylvania (the city of license), and a larger audience in
Wilkes-Barre.
A related problem was that of 'move-in'. Outlying communities would find their small-town local stations sold to outsiders, who would then attempt to change the community of license to a suburb of the nearest major city, move transmitter locations or remove existing local content from broadcasts in an attempt to move into the larger city.

WHMA-FM Anniston is now licensed as WNNX

Sandy Springs, Georgia—another
Atlanta suburb. Transmitters are now in downtown Atlanta.)
The same is true for WJSU, which served East Alabama with local news until the station was merged into a triplex to form
ABC 33/40 which focuses its coverage on the central part of the state.
A 1988 precedent case (Faye and Richard Tuck, 3 FCC Rcd 5374, 1988) created the "Tuck Analysis" as a standard which attempts to address the Suburban Community Problem on a case-by-case basis by examining:
# the station's proposed signal coverage over the urbanized area (the "Coverage Factor");
# the relative population size and distance between the suburban community and the urban market (the "Relative Size and Distance Factor"); and
# the independence of the suburban community, based on various factors that would indicate self-sufficiency (the "Independence Factor").
Despite the best intentions of regulators, the system remains prone to manipulation.
Licensing and on-air identity
While becoming less meaningful over the decades, stations are still required to post a
public file somewhere within 25 miles of the city, and to cover the entire city with a local
radio signal. In the United States, a station's
transmitter

must be located so that it can provide a strong signal over nearly all of its "principal community" (5 mV/m or stronger at night for AM stations, 70 dbuV for FM, 35 dbu for DTV channels 2–6, 43 dbu for channels 7-13 and 48 dbu for channels 14+), even if it primarily serves another city. For example, American television station

, stations in the Green Bay–Appleton area identify as "Green Bay/
Fox Cities" (e.g. "

There is no longer a requirement to carry
programs relevant to the particular community, or even necessarily to operate or transmit from that community. Accordingly, stations licensed to smaller communities in major
metropolitan markets often target programming toward the entire market rather than the official home community, and often move their studio facilities to the larger urban centre as well. For instance, the Canadian radio station
CFNY-FM is officially licensed to

civic pride, only to move it to some larger center which already has multiple stations.

was created in 1997. To operate a licensed station, a broadcaster must first obtain allocation of the desired frequencies in the FCC's Table of Allotments for the intended city of license. This process is subject to various political and bureaucratic restrictions, based on considerations including the number of existing stations in the area.
The term "city" has in some cases been relaxed to mean "community", often including the unincorporated areas around the city that share a mailing address. This sometimes leads to inconsistencies, such as the licensing of one
metro Atlanta station to the unincorporated
Cobb County community of
Mableton, but the refusal to license
another to
Sandy Springs, which is one of the largest cities in the state, and was at the time an unincorporated part of
Fulton County due to political complications involving its eventual incorporation from both the state and its containing county of
Fulton.
The definition of a "community" also comes into play when a broadcaster wants to take a station away from a tiny hamlet like
North Pole, New York, whose population is in decline. In general, regulators are loath to allow a community's only license to be moved away - especially to a city which already has a station. A broadcaster may make the case that the "community" functionally no longer exists in order to be released from its local obligations.
Often, the city of license does not correspond to the location of the station itself, of the primary audience or of the communities identified in the station's branding and advertising.
Some of the more common reasons for a community of license to be listed as a point far from the actual audience include:
The "compromise" location
A broadcaster may wish to serve two different communities, both in the same region but far enough from each other that a transmitter in one market would provide poor service to the other. While a transmitter in each community served would be preferable, occasionally a station licensed to a small town between the two larger centres will be used.

. As cities expanded, former small-town FM stations found themselves not only in what were now becoming rapidly expanding suburbs but also on what was becoming some of the most valuable spectrum in broadcast radio. The once-tiny FM stations would often then be sold, increased (where possible) to much-higher power and used to serve a huge mainstream audience in the larger metropolitan area.

co-channel interference

, a minimum distance is maintained between stations operating on the same frequency in different markets. On
VHF, full-power stations are typically 175 miles or more apart before the same channel is used again. An otherwise-desirable channel may therefore be unavailable to a community unless either it is operated at greatly reduced-height and power, forced onto a strongly directional antenna pattern to protect the distant co-channel station or relocated to some other, more distant location in the region to maintain proper spacing. The choice of another community as home for a station can be one possible means to avoid short-spacing, effectively shifting the entire station's coverage area to maintain the required distances between transmitters.

Burlington, both on

) - lower ground which in turn would be surrounded by tall mountain peaks. The only reliable means to get the
VHF television or radio signals over the mountains was to build a station atop one of the mountain peaks. This occasionally left stations with a distant mountaintop (or its nearest small crossroads) as the historical city of license, even though the audience was elsewhere.
The relocation of an existing station
Often, a license for a new station will not be available in a community, either because a regulatory agency was only willing to accept new applications within specified narrow timeframes or because there are no suitable vacant channels. A prospective broadcaster must therefore buy an existing station as the only way to readily enter the market, in some cases being left with a station in a suburban, outlying or adjacent-market area if that were the only facility available for sale.
The border blaster
Occasionally, a community on an international border is served using a
station licensed to another country. This may provide access to less restrictive broadcast regulation or represent a means to use
local marketing agreements or adjacent-market licenses to circumvent limits on the number of stations under common ownership.
The last-available frequency allocation
In the early days of television, the majority of stations could be found on the
VHF band; in North America, this currently represents just twelve possible channels and in large markets any suitable allocations in this range were mostly full by the early 1950s. Occasionally, a prospective broadcaster could obtain one of these coveted positions by acquiring an existing station or permit in an adjacent community - although in some cases this meant a move out-of-state.
The new entrant
A new network or station group will often enter a market after all of the most valuable available frequencies (such as the analogue VHF TV assignments in major cities) are already taken. This often results in building a network by constructing outlying stations, UHF stations, underpowered stations or some mix of all three. That can leave transmitters licensed to some very strange or tiny places. This happened to some degree with networks which signed on in the 1960s, such as

(VHF 6,
CBC Montréal) less than 120 miles distant - and this at a time when full-power VHF TV co-channel stations were typically spaced 175-200 miles (280-320km) apart to prevent interference.
The majority of these transmitters were not licensed to the primary community served. Many were underpowered, short-spaced or in undesirable locations - often just putting enough signal into key communities to obtain cable
must-carry protection. As the only transmitters to be operating on then-valuable VHF channels at anything other than greatly-reduced power were licensed to Paris and Bancroft, both awkward outlying communities, the Paris transmitter was arbitrarily listed as the main station for the entire network.
The cable or digital TV placeholder
Sometimes, putting a usable over-the-air signal into the primary community served is anywhere from second-priority to not a priority at all. A station could be
barely within the
market's boundaries or be underpowered to the point of putting a "B" grade signal into the community at best. On anything less than a huge rooftop antenna, the station is unwatchable — but, even if the underlying over-the-air signal was not valuable, the corresponding

slots in the various communities it was almost serving were. Any full-service domestic signal above some arbitrary minimum had access to "
must carry" protection, could request favourable placement on the dial and (in Canada) could engage in
signal substitution to take ad revenue from other stations already carrying the same content.
The
2016-2020 OTA TV repack opened additional possibilities for using an outlying community's licence as an over-the-air placeholder. Buy a station, return the licensed broadcast spectrum to the government, then claim to be "sharing" a channel with another broadcaster by using the orphan licence to place content on one of their
digital subchannels. Suddenly, an outlying commercial low-power station in

market. The same transmitter can, by using two different licences in a "channel sharing" arrangement, have two different communities of licence - which may allow more flexibility for its location. It is also possible to mix commercial and non-commercial licences. In Canada, where
CRTC regulations prevent carrying any additional, unique programming on digital subchannels without obtaining a second licence (and taking all the obligations which go with it) for each subchannel, returning just the spectrum (and keeping the licence) can be used as a means to recycle licences from abandoned, defunct outlying stations for use elsewhere in the network.
The use of an adjacent market
Occasionally, a station owner would reach a legal limit on
concentration of media ownership, already having the maximum number of commonly owned stations in a market. Additional stations would be possible by transmitting the extra signals from a station technically in an adjacent market.
The arbitrary nominal location
In some cases, stations were constructed or acquired with the express purpose of driving a regional or province-wide chain of full-power repeaters. Which of these "satellite stations" would be designated as the main signal could be an arbitrary choice, as the programming carried on all stations in the system would be identical.
