From inception for over 20 years, Radio 1 broadcast from an adjacent pair of continuity suites (originally Con A and Con B) in the main control room of Broadcasting House. These cons were configured to allow DJs to operate the equipment themselves and play their own records and jingle cartridges (called self-op). This was a departure from traditional BBC practice, where a studio manager would play in discs from the studio control cubicle. Due to needle time restrictions, much of the music was played from tapes of BBC session recordings. The DJs were assisted by one or more technical operators (TOs) who would set up tapes and control sound levels during broadcasts.

In 1985, Radio 1 moved across the road from [[Broadcasting House]] to [[Egton House]]. The station moved to [[Yalding House]] in 1996, and Egton House was demolished in 2003 to make way for an extension to Broadcasting House. This extension would eventually be renamed the Egton Wing, and then the Peel Wing.

Until 2012, the studios were located in the basement of Yalding House (near to BBC Broadcasting House) on [[Great Portland Street]] in [[central London]]. They used to broadcast from two main studios in the basement; Y2 and Y3 (there is also a smaller studio, YP1, used mainly for production). These two main studios (Y2 and Y3) are separated by the "[[Live Lounge]]", although it is mainly used as an office; live sets are rarely recorded from it, for [[Maida Vale Studios]] is used instead for larger set-ups. The studios are linked by webcams and windows through the "Live Lounge", allowing DJs to see each other when changing between shows. Y2 is the studio from where ''[[The Chris Moyles Show]]'' was broadcast and is also the studio rigged with static cameras for when the station broadcasts on the "Live Cam".

In December 2012, Radio 1 moved from Yalding House to new studios on the 8th floor of the new BBC Broadcasting House, Portland Place, just a few metres away from the "Peel Wing", formerly the "Egton Wing", which occupies the land on which Egton House previously stood: it was renamed the "Peel Wing" in 2012 in honour of the long-serving BBC Radio 1 presenter, [[John Peel]], who broadcast on the station from its launch in 1967 until his death in 2004.

Programmes have also regularly been broadcast from other regions, notably ''The Mark and Lard Show'', broadcast every weekday from [[New Broadcasting House (Manchester)|New Broadcasting House]], Oxford Road, [[Manchester]] for over a decade (October 1993–March 2004).

In August 2022, the studio 82A (from which Radio 1 broadcasts) was renamed 82Mills, following the departure of the long-running DJ [[Scott Mills]].<ref>{{cite tweet|number=1562776624898396162|user=BBCR1|title=Live from the new ✨82Mills Studio✨}}</ref>

===UK analogue frequencies===
Radio 1 originally broadcast on {{frequency|1215|kHz}}<ref>{{cite web |title=Radio 1 History – Transmitters |url=https://www.radiorewind.co.uk/radio1/transmitter.htm |publisher=Radio Rewind |access-date=7 October 2021}}</ref> [[medium wave|AM]] (or 247 metres). On 23 November 1978, the station was moved to {{frequency|1053 |kHz}} and {{frequency|1089|kHz}} (275 and 285 m).

The BBC had been allocated three FM frequency ranges in 1955, for the then [[BBC Light Programme|Light Programme]] (now [[BBC Radio 2]]), [[BBC Third Programme|Third Programme]] (now [[BBC Radio 3]]) and [[BBC Home Service|Home Service]] (now [[BBC Radio 4]]) stations. When Radio 1 was launched, there was no FM frequency range allocated for the station. The official reason given was that there was no space, even though no commercial stations had yet been launched on FM. As a compromise, Radio 1 was allocated Radio 2's FM transmitters for a few hours each week - on Saturday afternoons from 1pm until 7pm, Sunday teatime from 5pm until midnight, Monday to Friday nights from 10pm until midnight (This was also due to the AM signal tropo interference from Europe at that time) and Bank Holiday afternoons from 2pm until 7pm when Radio 2 was broadcasting on medium wave, the holiday edition of ''[[5 Live Sport|Sport on 2]]''.

===Full-time FM broadcasting===
Due to the rising competition from commercial FM stations, the BBC began to draw up plans for Radio 1 to broadcast on FM full time. This process began in London on 31 October 1987, at low power on a temporary frequency of {{frequency|104.8|MHz}}.<ref>{{cite web |title=Plans for Radio 1 FM services introduction |url=http://www.radiorewind.co.uk/images/transmitfm_sht1.jpg|publisher=Radio Rewind |access-date=20 May 2014}}</ref> The Department of Trade and Industry (predecessor to [[Ofcom]]) who were then the regulators for allocation of radio bandwidths in the UK, began to free up FM police and emergency communication frequencies which were operating from 97.9&nbsp;MHz to 102.0&nbsp;MHz. This was in preparation for new FM radio stations planned for the future. The BBC acquired 97.9 FM to 99.8 FM specifically for Radio 1.

The rollout of Radio 1 on FM nationally began on 1 September 1988, starting with [[Central Region, Scotland|Central Scotland]] (98.6&nbsp;MHz), the [[Midlands]] (98.4&nbsp;MHz) and the north of England (98.8&nbsp;MHz).<ref name="radiorewind1" /> On 24 November 1988, [[Belfast]] was added to the network on another temporary frequency on 96.0&nbsp;MHz.

From October 1988, due to the expansion of Radio 1's FM network, Radio 1 scaled back its airtime on Radio 2's FM frequencies in two phases - Phase 1 ending on weeknights (10pm–midnight) and Sunday evenings (7pm–midnight). As the FM engineering programme progressed, Phase 2 was introduced  from March 1990 - ceasing Saturday afternoons (1pm to 7pm) and the Sunday slot for the UK Top 40 (5pm-7pm). After 23 years, the shared FM frequency alliance between Radios 1 and 2 came to an end.

This resulted with BBC Radio 2 transmitting on FM full-time, where Radio 2's former AM frequencies - 693 & 909 - were allocated to BBC Radio 5.

Radio 1 made great efforts to promote its new FM service, renaming itself on-air initially as 'Radio 1 FM' and later as '1FM' until 1995. After reorganisation and a change of [[transmitter]] reallocation of the FM frequencies, especially in London (from 104.8 to 98.8&nbsp;MHz), the Midlands (98.4 to 97.9&nbsp;MHz) and Belfast (96.0 to 99.7&nbsp;MHz), the engineering programme was completed in 1995.

Until 2024, the station's [[Radio Data System|RDS]] name displayed "Radio 1". Since 2024 the RDS name now displays as "BBC R1" in line with the other BBC stations.

===End of medium wave broadcasting -  1053 / 1089 kHz===
The Conservative government decided to increase competition on AM and disallowed the [[simulcasting]] of services on both AM and FM, affecting both BBC and [[Independent Local Radio]]. Radio 1's [[medium wave]] frequencies were reallocated to [[Independent National Radio]]. Radio 1's last broadcast on MW was on 1 July 1994, with [[Stephen Duffy]]'s "Kiss Me" being the last record played on MW just before 9{{nbsp}}am. For those who continued to listen, just after 9{{nbsp}}am, Radio 1 jingles were played in reverse chronological order ending with its first jingle from 30 September 1967. In the initial months after this closure, a pre-recorded message by [[Mark Goodier]] was played to advise listeners that Radio 1 was now an "FM-only" station and to retune to the FM frequency.<ref name="Radio 1 transmitter AM switchoff">{{cite web|url=http://www.radiorewind.co.uk/radio1/transmitter.htm|title=Radio 1 History – Transmitters|publisher=Radio Rewind|access-date=20 May 2014}}</ref> Around this time, Radio 1 began broadcasting on spare audio subcarriers on [[Sky Television (1984–1990)|Sky Television's]] via Astra's SES satellite analogue service; initially in mono (on [[Gold (UK TV channel)|UK Gold]]) and later in stereo (on [[Sky Living|UK Living]]) transponders. The 1053 / 1089 frequencies were allocated to the then newly created Talk Radio UK.

===Digital distribution===
The BBC launched its national radio stations on [[Digital Audio Broadcasting|DAB]] digital radio in 1995; however, the technology was expensive at the time and so was not marketed, instead used as a test for future technologies. DAB was "officially" launched in 2002 as sets became cheaper. Today it can also be heard on UK digital TV services [[Freeview (UK)|Freeview]], [[Virgin Media]], [[Sky (UK and Ireland)|Sky]] and the Internet as well as FM. In July 2005, [[Sirius Satellite Radio]] began [[simulcast]]ing Radio 1 across the United States as channel 11 on its own service and channel 6011 on [[Dish Network]] satellite TV. [[Sirius Canada]] began simulcasting Radio 1 when it was launched on 1 December 2005 (also on channel 11). The Sirius simulcasts were [[Time shifting|time shifted]] five hours to allow US and Canadian listeners in the [[Eastern Time Zone (North America)|Eastern Time Zone]] to hear Radio 1 at the same time of day as UK listeners. On 12 November 2008, Radio 1 made its debut on XM Satellite Radio in both the US and Canada on channel 29,{{citation needed|date=May 2011}} moving to XM 15 and Sirius 15 on 4 May 2011.<ref>{{cite web|url=http://www.siriusxm.com/pdf/11-524_SIR_WebLUs_5_4.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.siriusxm.com/pdf/11-524_SIR_WebLUs_5_4.pdf |archive-date=2022-10-09 |url-status=live|title=Sirius Channel Lineup|date=2 May 2011|access-date=4 May 2011}}{{dead link|date=July 2017|bot=InternetArchiveBot|fix-attempted=yes}}</ref><ref>{{cite web|url=http://www.siriusxm.com/pdf/11-524_XM_WebLUs_5_4.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.siriusxm.com/pdf/11-524_XM_WebLUs_5_4.pdf |archive-date=2022-10-09 |url-status=live|title=XM Channel Lineup|date=2 May 2011|access-date=4 May 2011}}{{dead link|date=July 2017|bot=InternetArchiveBot|fix-attempted=yes}}</ref> Until the full station was removed in August 2011, Radio 1 was able to be heard by approximately 20.6&nbsp;million listeners in North America on satellite radio alone.
BBC Radio 1 can be heard on cable in the Netherlands at 105.10 FM.

===SiriusXM cancellation in North America===

At midnight on 9 August 2011, [[Sirius XM Radio|Sirius XM]] ceased carrying BBC Radio 1 programming with no prior warning. On 10 August 2011 the BBC issued the following statement:
<blockquote>The BBC's commercial arm BBC Worldwide has been in partnership with SIRIUS Satellite Radio to broadcast Radio 1 on their main network, since 2005. This agreement has now unfortunately come to an end and BBC Worldwide are in current discussions with the satellite radio station to find ways to continue to bring popular music channel, BBC Radio 1, to the US audience. We will keep you posted.<ref>{{cite web | url=https://www.bbc.co.uk/pressoffice/bbcworldwide/worldwidestories/pressreleases/2011/08_august/r1_sirius.shtml | title=Radio 1 – Sirius | work=BBC Worldwide Press Releases | publisher=BBC | date=10 August 2011 | access-date=12 October 2013 | archive-date=25 May 2012 | archive-url=https://web.archive.org/web/20120525024231/http://www.bbc.co.uk/pressoffice/bbcworldwide/worldwidestories/pressreleases/2011/08_august/r1_sirius.shtml | url-status=dead }}</ref></blockquote>

Thousands of angry Sirius XM customers began a campaign on Facebook and other social media to reinstate BBC Radio 1 on Sirius XM Radio.<ref>{{cite web | url=https://www.facebook.com/SaveRadio1inNorthAmerica | title=Get BBC Radio 1 Back on Sirius XM | via=Facebook | access-date=12 October 2013}}</ref>{{Primary source inline|date=May 2022}}{{Primary source inline|date=January 2020}} One week later, Sirius and the BBC agreed on a new carriage agreement<ref>{{cite web|url=http://www.siriusxm.com/bbcradio1 |title=BBC Radio 1 – British Pop hits from U.K. Charts – SiriusXM Radio |publisher=Siriusxm.com |access-date=20 May 2014 |url-status=dead |archive-url=https://web.archive.org/web/20140516153430/http://www.siriusxm.com/bbcradio1 |archive-date=16 May 2014 }}</ref> that saw Radio 1 broadcast on a time-shifted format on the Sirius XM Internet Radio platform only, on channel 815.

Starting on 15 January 2012, ''The Official Chart Show'' began broadcasting on SiriusXM ''20on20'' channel 3, at 4{{nbsp}}pm and 9{{nbsp}}pm [[Eastern Time Zone|Eastern Standard Time]].<ref name="Bowman">{{cite web |last1=Bowman |first1=Samantha |title=Weekly countdown of the UK's top 40 songs to air on SiriusXM's 20 on 20 channel |url=http://investor.siriusxm.com/investor-overview/press-releases/press-release-details/2012/BBC-Radio-1s-The-Official-Chart-with-Reggie-Yates-to-Air-on-SiriusXM/default.aspx |website=SiriusXM |publisher=SiriusXM Radio |access-date=1 December 2019}}</ref>

===Regionalisation===<!-- This section is linked from [[BBC Northern Ireland]] -->
From 1999 until 2012, Radio 1 split the [[home nations]] for localised programming in Scotland, Wales and Northern Ireland, to allow the broadcast of a showcase programme for regional talent. Most recently, these shows were under the [[BBC Introducing]] brand. Scotland, Wales and Northern Ireland had their own shows, which were broadcast on a 3-week rotational basis in England.

From January 2011 until June 2012, Scotland's show was presented by Ally McCrae.<ref>{{cite web|url=https://www.bbc.co.uk/programmes/b00x592r |title=BBC Radio 1 – BBC Introducing in Scotland with Ally McCrae |publisher=BBC |date=11 June 2012 |access-date=20 May 2014}}</ref> Previously it was hosted by [[Vic Galloway]] (who also presents for [[BBC Radio Scotland]]); who had presented the show solo since 2004, after his original co-host Gill Mills departed.

Wales's show was hosted by Jen Long between January 2011 until May 2012.<ref>{{cite web|url=https://www.bbc.co.uk/programmes/b00x592p |title=BBC Radio 1 – BBC Introducing in Wales with Jen Long |publisher=BBC |date=28 May 2012 |access-date=20 May 2014}}</ref> Previously [[Bethan Elfyn]] occupied the slot, who had at one time hosted alongside Huw Stephens,<ref name="regions98">{{cite web|url=http://frequencyfinder.org.uk/r1_sched_98_04.html |title=Frequency Finder UK – Classic Radio 1 schedules |publisher=Frequencyfinder.org.uk |date=25 October 2004 |access-date=20 May 2014 |url-status=dead |archive-url=https://web.archive.org/web/20131111133603/http://frequencyfinder.org.uk/r1_sched_98_04.html |archive-date=11 November 2013 }}</ref> until Stephens left to join the national network, although he still broadcasts a show for Wales – a Welsh-language music show on [[BBC Radio Cymru]] on Thursday evenings.

Phil Taggart presented the Northern Ireland programme between November 2011 and May 2012. The show was formerly presented by [[Rory McConnell]]. Before joining the national network, [[Colin Murray]] was a presenter on ''The Session'' in Northern Ireland, along with Donna Legge;<ref name="regions98" /><ref>{{cite web|url=http://www.culturenorthernireland.org/article.aspx?art_id=1253 |title=Who is Colin Murray? |publisher=Culturenorthernireland.org |date=19 September 2008 |access-date=20 May 2014 |url-status=dead |archive-url=https://web.archive.org/web/20141110024216/http://www.culturenorthernireland.org/article.aspx?art_id=1253 |archive-date=10 November 2014 }}</ref> after Murray's promotion to the network Legge hosted alone for a time, and on her departure McConnell took her place.

The regional opt-outs originally went out from 8{{nbsp}}pm to 10{{nbsp}}pm on Thursdays (the ''Evening Session''{{'}}s time slot) and were known as the "Session in the Nations" (the "Session" tag was later dropped due to the demise of the ''Evening Session''); they later moved to run from 7:30{{nbsp}}pm to 9{{nbsp}}pm, with the first half-hour of Zane Lowe's programme going out across the whole of the UK. On 18 October 2007 the regional programmes moved to a Wednesday night/Thursday morning slot from midnight to 2{{nbsp}}am under the ''BBC Introducing'' banner, allowing Lowe's Thursday show to be aired across the network; prior to this change Huw Stephens had presented the Wednesday midnight show nationally. In January 2011, BBC Introducing was moved to the new time slot of midnight to 2{{nbsp}}am on Monday mornings, and the Scottish and Welsh shows were given new presenters in the form of Ally McCrae and Jen Long.

The opt-outs were only available to listeners on the FM frequencies. Because of the way the DAB and digital TV services of Radio 1 are broadcast (a single-frequency network on DAB and a single broadcast feed of Radio 1 on TV platforms), the digital version of the station was not regionalised.

The [[BBC Trust]] announced in May 2012 that the regional music programmes on Radio 1 would be replaced with a single programme offering a UK-wide platform for new music as part of a series of cost-cutting measures across the BBC.<ref>{{cite web|url=https://www.bbc.co.uk/news/entertainment-arts-18083178 |title=Children's shows to leave BBC One |publisher=BBC |date=16 May 2012 |access-date=20 May 2014}}</ref> In June 2012, the regional shows ended and were replaced by a single ''BBC Introducing'' show presented by Jen Long and [[Ally McCrae]].<ref>{{cite web|url=https://www.bbc.co.uk/programmes/b01jk7zb |title=BBC Radio 1 – BBC Introducing with Jen and Ally |publisher=BBC |date=1 January 1970 |access-date=20 May 2014}}</ref>
