DAB and DAB+: Some Testing Ahead of SDL/D2 Launch Next Week

125 DAB and DAB+ Services

Rupert Brun, expert on all things audio and late of the BBC, has been testing his radios at ahead of the Sound Digital (SDL) launch in a week’s time. The multiplex is in full test mode at the moment, so if you want to know if you can hear the new services, then a rescan of your radio may be in order.

Rupert first compiled his results on his blog (direct link), and has gone on to produce a Google Doc of the results including those of others.

So I’ve decided to test my own radios allowing Rupert to incorporate them into his results.

First of all I should note, as the photo above shows, that I’m in a rather fortunate location with regard to DAB/DAB+ radio. I live in north London, inside the M25, but close to the green belt. I’m also high up (at least for London) at somewhere around 70m above sea level. What that all means is that my radios will currently tune in 125 different services coming from the following multiplexes

  • BBC National
  • D1 National
  • SDL National
  • London 1
  • London 2
  • London 3
  • London Trial
  • Herts, Beds & Bucks
  • Essex
  • Kent
  • Surrey

I am somewhat surprised that I can get the Surrey multiplex, since it’s geographically the other side of London. And to be honest, reception is poor – but listenable. Kent might seem as far, but historically FM services have always reached this part of north London, and the closest transmitter for that mulitplex is actually in Benfleet in Essex.

Anyway, here are the results of my radios. I’ve included the number of services tuned into to give you an idea of the sensitivity of these sets. I tested them all with their own built in antennae, except the portable models where I used a set of ear-buds extended vertically.

*Note that Rupert measures both sets that present DAB+ services that can’t be tuned, and those who can’t tune them, so hide them, as both “Poor.” That’s true, but I think it’s a better user experience to hide services that can’t be tuned. It you see a service and tune to it, it looks like there’s either a problem with your radio, or perhaps the station is off-air.

In summary, the more expensive radios – the first three Roberts models – all did fine. Which is as well, since these are my most used radios, and also deliver by far the best sound. I’m unsurprised that none of the portable models tested works, but I do have a new Pure Move 2500 – untested because I left it at my parents’ house accidentally – which should give me DAB+. And none of my cheap models surprised me by revealing that they were indeed DAB+ compatible.

Two more thoughts on my testing:

– The test audio that SDL is currently broadcasting for Virgin Radio is truly awful in sound quality. While the service will only be 80k mono, it sounds like they’re playing a 32k mp3. Not the best way to show off a new service.

– My radios get a lot of Heart stations. And it’s not always easy to tell them apart. In order I get the following:

Heart – Herts, Beds & Buck
Heart – London 1
Heart Kt – Kent
Heart Su – Surrey
Heart Sx – Essex (esS eX – geddit!)

You’ll note that the first two are indistinguishable from the short version of the DAB label. I have to tune to one of them and then hit “info” a few times to determine which multiplex I’m listening to.

When Heart Extra launches in a few days that’ll be one more! (With the London breakfast show carried on the service competing with all the local Heart breakfast shows.)

I know that DAB labels aren’t easy to manage. I once battled with naming all the Absolute Radio services, trying to get radios to sort them in a logical order. Unfortunately, what’s logical on one radio, isn’t on another – different brands and models use different sorting algorithms! So trying to get Absolute Radio 60s, 70s, 80s, 90s and 00s, along with the main brand and classic rock, into a sensible order proved impossible.

D2: All Coming Together

US 2014-90

NB. This is not a DAB radio. The picture above is of possibly the most beautiful radio I’ve ever seen in my life. It’s the Nocturne, made in 1935 by a US company called Sparton and designed in Art Deco style by Walter Dorwin Teague. This one sits in the Wolfsonian museum in Miami. If you want one, there’s a YouTube video showing a 2012 auction with one going for $34,000, so you may have to start saving. This radio has a whole website dedicated to it, where you’ll notice that teaser adverts for forthcoming new models are nothing new!

In my recent RAJAR post, I wrote a little about the second national commercial multiplex – Sound Digital – which is due to launch from the 29th February (with some services launching across the following month).

The full line-up of services has been announced, and we’re now getting a drip-feed of more details about who will be on those services.

First properly out of the gate is the new TalkRadio. I’ve long thought that UK radio is under-served by speech, with essentially four national speech services currently available. LBC was very late in the day in going national, but it has made a good fist of it, and in particular has delivered a lot of publicity by making a virtue of giving politicians of all hues their own shows.

TalkRadio looks like it’s going to be quite similar, but perhaps a little lighter in tone. Paul Ross, who seems to have had stints on just about every station going, but most recently on BBC Radio London’s breakfast show, will helm TalkRadio’s breakfast. Then comes Julia Hartley-Brewer, who has previously done a similar show on LBC. Sam Delaney moves over from TalkSport, and then there’s Iain Lee, who recently had a run-in with BBC Three Counties and left, with a return to late-night on TalkRadio being the obvious gig. However, I really could do without George Galloway though who I find abhorrent, and who has a tendency to take cash from the Iranian and Russian governments via their state broadcasters as well as say obnoxious things.

With LBC filled with ex-politicians like Iain Dale, occasional Newsnight presenter James O’Brien, former Five Live breakfast presenter Shelagh Fogerty and of course, Nick Ferrari, it feels like a slightly more current affairs driven service than TalkRadio.

The proof will be in the pudding of course, and with Dan Walker off from Five Live to BBC Breakfast, listeners may be exploring their dials to find something new to listen to.

Of course Five Live and TalkSport do have the advantage of analogue carriage. If you want TalkRadio, or LBC outside London, you do have to listen on a digital platform. That will affect audiences – particularly in-car because while new cars now nearly all come with DAB, the vast majority on the road don’t have it. But late nights in particular are going to be really interesting.

Next out the block is UTV’s other big new station, the reborn Virgin Radio. Considering I spent much of my working life at the original Virgin Radio (It launched in 1993, and I worked there from late 1996 until it re-branded in 2008), you might think that I have mixed views about this, but to be honest I don’t.

The big questions for me were always going to be: What kind of service would UTV offer, and was the Virgin Radio brand a bit passé in the UK? The new version of the station is interesting because UTV is a partner with Bauer Media (and Arqiva) in the multiplex, and Bauer’s Absolute Radio is the evolution of Virgin Radio. Christian O’Connell, Geoff Lloyd and Leona Graham are still there from the Virgin days, all in key shows. You would imagine that many of those legacy Virgin Radio listeners are now Absolute Radio listeners.

And whisper it, but I’m not sure Virgin is quite the sexy brand it once was. It’s a transport and finance brand these days, rather than record label and record store. Yes Virgin Atlantic is aspirational, and Virgin Media does a decent job. But it does feel a bit tarnished. Even the potential of Virgin Galactic has not been achieved.

Then there’s the marketplace for where a Virgin Radio music service might fit. While Virgin Radio isn’t a prescriptive service that comes with a set playlist – stations in Dubai and Thailand show that local Virgin Radios can be whatever the market dictates there’s a space for – there was a serious question about whether a relaunched Virgin should be recognisable from before, or something new. Should it just be Virgin Radio about ten years older? Well eight years on, anyway. Or do you disregard what Virgin Radio meant as a brand to listeners in the past, and do something new? If you choose the latter, what is the point of retaining the brand? I suppose the thinking is that like a movie studio relaunching a popular franchise for a new generation, the same can be true for a radio station.

Although I did see a UTV presentation recently that noted the continued strength of the Virgin Radio brand, that perhaps wasn’t surprising given the station’s previous life, and the fact that it had a very successful run with Chris Evans at the helm. And anyone who’s been through a station re-brand will know that old brands live on much longer in listeners minds than marketeers might perhaps hope.

Then there’s the question of the wider radio landscape and a new Virgin Radio’s place in it. As well as Absolute, in broadly the same musical area, there is the new Radio X with its massive marketing budget and big-name presenters, and BBC 6 Music which gets larger all the time and is undoubtedly the “cool” station of the day.

The announcement of the new Virgin Radio line-up suggests to me that they’re actually trying something a bit different! I will admit that I was surprised that UTV let Johnny Vaughan up and leave for Radio X, when they’d had him on contract for TalkSport, but budgets are always finite, and UTV will undoubtedly hae some realistic audience targets that take account of their distribution. So instead it looks like Liam Thompson, Virgin Radio’s Programme Director, is trying something much more interesting.

Having former Radio 1 presenter Edith Bowman at breakfast almost seems like a direct response to the “male-ness” of Radio X, or at least the marketing surrounding that station’s launch.

And putting Kate Lawler in the afternoon slot – formerly of Capital, Kerrang and more recently Bauer’s Big City network – compounds that feeling. National radio is certainly too male, remaining the Achilles heel of Radio 2. Of course it’s disappointing that it should even need to be noted that 2 out 4 daytime presenters are women, but that’s a reflection of our industry today.

Also in the line-up are people I’m less familiar with like Jamie East and Matt Richardson, neither of who’s output I’ve ever seen. This also suggests, that I’m outside the target market for the new Virgin.

Rounding things off is Tim Cocker, who many were disappointed to lose when Xfm rebranded, as he lost his Manchester breakfast slot.

Overall, this is a much more interesting Virgin Radio than I’d envisaged. Again, my fear is that there could be too much congestion for audiences, so marketing for this and the other new stations will be imperative. Cross promotion on Talk branded services might not be enough.

I’m still curious to see exactly what TalkSport 2’s schedule ends up looking like, and whether it’ll be closer to Five Live Sports Extra (some extra programming, but lots of filler/repeats when there’s nothing new), or whether it’ll be more of a full-service. The next UK radio rights package for the Premier League has yet to be announced, and TalkSport might try to take a little more to put something on their new service. But Championship football might be more affordable at a time when the company is making a lot of investment in UK radio, and ridding itself of television.

What press there has been for TalkSport 2 mentions cricket, football, golf, horse racing, tennis, rugby and US sport. They launch at the Cheltenham Festival, and that might suggest that afternoons will have a lot of racing. Putting US sport on overnight might be a smart idea. Five Live Sports Extra covered the NFL this season, and in the past, the World Series has been broadcast. The radio commentaries exist, and with baseball, NBA and NFL (maybe even MLS), it could be as simple as retransmitting those commentaries. I speak as someone who once upon a time used to tune into distant Armed Forces Network programmes on AM to drift off to sleep listening to baseball.

Overall though, UTV should have a much healthier network offering to sell to advertisers, and given that most of the market is driven by large “share deals” for Global and Bauer, this is imperative for them.

Elsewhere, it’s very sensible that instead of the originally planned TalkBusiness, UTV has done a deal for the slot with London station Share Radio. Their challenge will be finding that business niche and monetising it.

From Bauer, we have not one, but two Magic spin-offs. Mellow Magic (or, as it was briefly, and bizarrely known, “Magic Mellow”) is to be joined by Magic Chilled, perhaps a little bit of one-upmanship against the upcoming Heart Extra back on Digital One. I confidently expect these to work precisely as Absolute Radio’s digital brethren work with its main brand. While it remains to be seen whether that includes changing the breakfast show music as Absolute does for Christian O’Connell, I would expect the same Magic presenters to be voice-tracking some more specialist versions of the Magic oeuvre, with perhaps a couple of new names helping out. The Absolute Radio Network model has proved itself.

The rest of Bauer’s services are either stations shifted from Digital One, to a perhaps more cost-effective platform, or moved up from local DAB multiplexes, where Bauer has a substantial shareholding.

Nearly all the rest of the DAB services on D2 are spin-offs of existing services. So Premier gets a second service, Premier Praise, as its main brand shifts multiplexes too. UCB 2 is another Christian service, previously available in London, while Sunrise and Panjab move up to a national platform.

The only other completely new service seems to be Awesome Radio (previously called British Muslim Radio), coming from the people who run Asian Sound Radio in Manchester. You would imagine that they will be able to utilise existing studios and personnel to keep costs reasonable.

Finally there are the two other new DAB+ services. When Sound Digital won the multiplex, they only talked about a single DAB+ service, whereas rival bidder Listen2Digital was talking of offering 4 DAB+ services. The fact that the Sound Digital bid won without a named service in place, and that subsequently it was advertising for services willing to run in DAB+ was perhaps a little concerning.

DAB+ has always been a chicken and egg situation in the UK. Because DAB has been around since the end of the nineties, many radios in UK homes do not have DAB+ compatibility. In territories where digital has been adopted more recently, DAB+ was offered from the outset. While more recent models have included DAB+, if only because the radios were built for more than just the UK market, it isn’t clear what proportion of radio sets in use today are DAB+ compatible.

So while I’ve no doubt there’ll be some rough numbers kicking around, produced with the help of manufacturers, it’s still a leap of faith for a broadcast who wants to go DAB+ only. Some radios might be upgradeable, since the choice about whether to include the DAB+ codec was really more about the intellectual property licences payable rather than the hardware required. But how many consumers will actually seek out that information, and go to the effort of plugging memory sticks into USB ports?

Sound Digital’s solution is to offer two existing relatively niche services in DAB+, as well as the new Magic Chilled. Jazz FM’s was once available on Digital One, but latterly it was largely available online, with only some local DAB coverage. Getting national coverage is good for the service.

It’s a similar story with Fun Kids. They target an audience that even RAJAR doesn’t properly measure, and so they need to be careful about how they spend money on broadcast transmission.

You would imagine that all three services are getting a “good deal” from Sound Digital, with everyone watching with interest to see how successful the services are. Because if DAB+ is actually available more widely than previously realised, then we can expect more services to switch to it. It’s a more efficient use of the limited data available in DAB multiplex, and can offer – shock – stereo sound at a more affordable price to stations. Stereo is especially important to Jazz aficionados!

For what it’s worth, I’ve been retuning some of my own DAB sets at home, which are largely Roberts models, to receive the test Waves and Waves+ test stations. All three of my main radios are DAB+. But none of them are especially old. Other, older radios await a retune.

[Updated to reflect that Magic Chilled is also in DAB+]

[Update: I’ve now tested all my radios and the results are here.]

Looking Ahead to the Second National Digital Radio Multiplex

DAB Radio

Ofcom is finally closing its doors on applications for a second national commercial radio digital radio multiplex. Originally bids had to be in by the end of October 2014, but Ofcom extended its application period to the end of January 2015 when a potential bidder sought a Network Access-only reference offer from Arqiva. (Since Arqiva is provides transmission for the majority of radio services in the UK, a third party bidder would probably need to use Arqiva’s sites to broadcast from. As such, it has to provide third parties with separate costs, and until the third parties have put into place their broadcasting plans, Arqiva can’t provide those costs. Hence the delay.)

It’s thought that there will be two bidders – Sound Digital (an alliance of Arqiva, Bauer Media and UTV) and, potentially, a second group that has not yet been publicly announced.

Up until relatively recently national digital radio has had a bit of a roller-coaster existence. When national commercial DAB launched in 1999 the key stations to be found on it were the three analogue INRs: Classic FM, Virgin Radio (now Absolute Radio) and Talk Radio (now Talksport). Alongside were a number of new services that multiplex (“mux”) owners GWR Group and transmission supplier NTL, brought afresh. And so we had services with new brand names like Core, Capital Life and OneWord.

DAB set ownership was low, and while the INRs had all built analogue businesses to help them with the additional DAB transmission costs, the new brands struggled. Their owners were far more interested in their highly profitable local FM stations. Why waste marketing budget on new services that might actually cost you listeners?

In due course brands would come and go on Digital One. It was quite expensive to get carriage, but if you had the money, there was space available.

That ceased to be the case to an extent around 2006 when BT Movio launched. The mux’s licence allowed a proportion of the available space to be used as data – about 30%. BT Movio was an attempt to launch a mobile TV service using that space. Crucially though, it was a paid for service, and the only phone that was ever built that was capable of watching the service came from Virgin Mobile – the Lobster phone.

It was fine as far as it went, but the fact is that with few television choices, there was limited appeal for subscribers, so unsurprisingly BT announced the end of the service in 2007. The phone was reasonably decent though – at least as a phone with a DAB radio built in! (We’ve yet to see another phone come with DAB since then – although there are reports that LG might release a device).

It was also around this time that Ofcom decided to licence the second national digital radio multiplex for the first time. There were two bidders – 4 Digital*, a consortium led by the public sector broadcaster Channel 4, and National Grid Wireless. The 4 Digital bid was considered much more attractive and it was duly awarded the licence with planned new services including the flagship Channel 4 Radio (described as a Radio 4 competitor!), E4 Radio, Sky News Radio amongst others. But Channel 4 had over-expanded in television, and was having financial difficulties. So in 2008 it scrapped its plans to launch despite having won the licence. Ofcom was not happy, and although they held onto the frequencies, it took quite a few years before they could be persuaded to try licencing the mux once more.

So by 2008 with BT Movio having closed, and GCap (formed from the merger of GWR and Capital Radio) pulling off the platform, space had been freed up and was available. Few seemed interested in national DAB. The mux owners would broadcast Birdsong as a holding station when capacity wasn’t being fully utilised. And the mux was bought outright by Arqiva, the transmission provider that had become the defacto sole supplier in the UK having bought up its rivals.

But people were still buying DAB sets, and notably Absolute Radio, under new ownership and rebranded from Virgin Radio, jumped in at about this point. It first launched Absolute 80s and later Absolute Radio 90s on the national mux. It also played around with station labels when it first bought Premier League rights, and created Absolute Radio Extra.

All the while DAB penetration and listening had been creeping up, and more transmitters had been built. DAB was now working. Absolute 80s became the biggest commercial digital only station, and importantly it was sold on a network basis – advertisers buying across the whole suite of Absolute brands. There were fewer brands that existed solely as standalone DAB services.

In the last year or so, we’ve seen a number of bigger brands coming onto the platform and duplicating that work. Global has got fully behind national DAB – previously it had mostly concentrated on local multiplexes often part owned by them, its predecessor GCap having just about abandoned it. It launched Smooth Extra, Capital Xtra and LBC nationally. Bauer has bought Absolute Radio, and although Absolute Radio 90s got shifted off the platform, it now has Kiss, Magic and Planet Rock alongside the remaining Absolute stations on the mux.

Indeed at time of writing, the only remaining non-Global or Bauer stations still on the multiplex are BFBS (aimed at the armed forces and their families, and effectively an extension of the MOD), Premier Christian Radio, TeamRock and UCB UK. And it’s reported that Premier Christian Radio will have to make way for Global’s Heart Extra at some point.

Indeed there are now so many radio services on the mux, that only Classic FM and Capital Xtra are still broadcasting in stereo, since a multiplex has a limited amount of bandwidth and it can only be cut so many ways.

And so, finally, we reach the present day, and a second attempt to licence a second national DAB multiplex. Exactly what the winning group wants to do with the space remains to be seen. We’ll learn later this week what the respective plans are of the bidders.

Possibilities include:

– the launch of brand new services and formats
– the UK launch of international brands and stations
– additional sub-brands of existing properties (although arguably we’ve stretched these as far as they’ll go)
– national coverage for stations that haven’t found space on Digital One, or have had to make way for sister stations
– the opportunity to launch some services in DAB+ (see below)
– space for pop-up DAB services to run over short periods
– some clever mobile data usage

I would certainly expect the announcement of at least one new speech station – most other radio markets globally are able to sustain many more speech services than we have in the UK.

Of crucial importance for any standalone brands that launch will be their advertising sales strategy. Who will be selling their advertising for them?

And the other thing to look out for will be transmission plans. Rolling out new transmitters is an expensive business. The BBC continues to rollout masts for its national DAB mux to reach ever more of the population. Digital One reaches somewhere around 90% of the population, but the diminishing returns of population versus cost means that it’s unlikely to go much further. It seems likely that whoever wins the new mux won’t be so ambitious. Look for a potentially phased rollout that may never reach more than 75% or so of the population – i.e. the major towns and cities, and key trunk routes.

But perhaps the launch of some services in DAB+ is perhaps the most interesting prospect. DAB+ uses much more up to date audio compression meaning that lower bandwidths are capable of broadcasting higher quality audio than vanilla DAB can use.

In reality that means one of two things:

– a station can broadcast at a higher quality using its equivalent current capacity;
– or you can squeeze even more lower quality stations into the same space

As with DAB originally, there’s also a chicken and egg situation with DAB+ in that probably the majority of DAB sets in the UK marketplace today are not DAB+ enabled. That means that they can’t receive DAB+ services. Some of them will be up-datable with a firmware upgrade. But that’s not as easy to do with a radio as it is, say, with a PC or smartphone. You can’t just roll-out an update that users click on. It tends to involve downloading files to USB sticks from PCs and going into unusual menus on radio sets.

Most DAB sets currently in the market are DAB+ compatible, but given the slow replacement cycle of radios compared with many other consumer electronic goods, getting everyone over to DAB+ will take some time.

Additionally, Ofcom has placed some odd limitations on what mux owners can do with DAB+. It has said that no more than 30% of the new mux’s capacity should be used for DAB+ stations. It wants to make sure new services are mostly available to all.

In other words, a new bidder would be unable to launch with a complete roster of DAB+ stations even if it wanted to.

That feels wrong to me. This seems like it is something the commercial broadcasters, set manufacturers and the marketplace can sort out between themselves. The market will dictate the speed of DAB+ roll-out.

If a a service provider chooses to broadcast in DAB+ then it is up to them to make the gamble that they can achieve a big enough audience to sustain such a service. Indeed, if a broadcaster chooses to make a particularly attractive range of options behind a DAB+ “wall” then it might be able to drive DAB+ uptake on its own.

Realistically, no bidder is going to limit listeners unless they can make a commercial argument to do so. Intervention feels unnecessary.

Looking across the Atlantic is instructive. When Sirius (now Sirius XM) signed Howard Stern away from free-to-air radio to their then new subscription satellite radio service, they made the gamble that he was a big enough name to motivate his listeners into both investing in new hardware and paying a subscription to carry on listening to his show. Would enough people be prepared to upgrade to DAB+ to hear, ooh, let’s say Chris Moyles? I don’t know, but I think it should be for broadcasters to make that judgement, not the regulator.

Ofcom has said it will review the limit in 2018.

In any case, right now this is all moot. We’ll find out what the broadcasters have come up with later this week!

* At time of writing, the 4Digitial site is still there, buried away on the Channel 4 website – proudly proclaiming their winning bid!

[Updated to include reference to pop-up DAB services which I forgot to mention initially, and was in no way prompted to add after the BBC announced a pop-up Country radio service]

Disclaimer: These are my own views, and do not represent those of my current or former employers. I did work at Absolute Radio at the time it launched its digital sub-brands, and I helped with the Virgin Radio proposed service – Virgin Viva – as part of the 4 Radio bid back in 2007. SMG, then owners of Virgin Radio, never signed on the line, hence Viva wasn’t formally listed as part of the bid.

Radio Extra

Earlier this week, Global announced that it would soon be launching Heart Extra on national DAB. This is the first of a big DAB push.

They already have Smooth Christmas running on the platform, and that rebrands as Smooth Extra from December 27th. They also have Capital XTRA, LBC and Classic FM all on the same DAB multiplex. The press release also promises “more to come,” although it’s not clear how many more stations “more” means.

Anyway, for Global to add one additional station to the D1 line-up, something has to give. That means one current station has to go to make way for Heart Extra. We know a Global station isn’t going. And Bauer has announced longer term plans for its digital portfolio, including replacing Absolute Radio 90s with Magic.

And we can be certain too that Talksport isn’t going anywhere.

So that leaves three independent services: BFBS, Premier Christian Radio and UCB Christian radio. I believe that at least one of those has to go to make room for Heart.

Furthermore, depending on what kind of bitrate Global wants to run Heart Extra at, they may have to play around with the bitrates of their other stations if they want to broadcast Heart Extra at 80k mono.

For all things bitrate and multiplex related, the go-to site is Wohnort DAB, so I’ve used their reports of the current state of play as a jumping off point.

Here’s a view of what the radio services look like currently, and what they’ll possibly look like in 2015 once Heart Extra is on-air.

The three at risk stations are italicised at the bottom of the right hand side of the table.

Furthermore, for Global to launch another DAB service right now, then a second of these stations would need to go as well.

Another thing to consider is the forthcoming “D2” multiplex. There was a late extension from Ofcom for applications, strongly suggesting that we will see at least two competitive bids by the closing date at the end of January. That said, you may see some of the same services crop up on both bids.

The timetable from the end of January is for Ofcom to look at the applications, fire lots of questions at the applicants and generally put everyone through the mill. Ofcom says that it will announce an award “as soon as practicable thereafter.” I would anticipate an announcement sometime during the summer. In reality, that means the earliest new services could get up and running would be sometime in early 2016, so there’s a while to go before any more new space appears.

What all this means is that if a service gets bumped off Digital One today (or outbid anyway), then it’s going to take them a while to get back onto a national DAB multiplex, because it’ll be another year before more space is available.

It’ll be interesting to see what Global and others do in the meantime.

[Update: 16 December 2014] It’s now official that Premier Christian Radio hasn’t secured an extension to its place on Digital One. Radio Today reports that Premier has a temporary extension allowing them to run from this weekend through Christmas until February. But it’s clear that Premier wants to remain on the multiplex, while Global claims to have “more to come.” Arqiva won’t be complaining then…
