DAB+ appears on Brighton Trial Mux
both new and existing stations have gone DAB+
http://www.wohnort.org/DAB/ukloc.html#Brighton Mini MiSoul 48 kbit/s DAB+ Radio Caroline 32 kbit/s DAB+ Resonance 64 kbit/s DAB+ Smile Sussex 48 kbit/s DAB+ Solar Radio 48 kbit/s DAB+ Trickster 48 kbit/s DAB+ URF 64 kbit/s DAB+ 1 BRIGHTON FM 80 kbit/s Mono Gaydio 80 kbit/s Mono Juice 107.2 192 kbit/s Stereo Radio Reverb 192 kbit/s Stereo total 1088 (maybe room for more) There's a possibility that both Gaydio and 1 BRiGHTON FM, may go DAB+ next year as they have both been awarded community FM licenses |

64kbps DAB+ on a UK multiplex? Either a typo or it's happening!

Yes, another trial multiplex moving forward. Still nothing from London or the big boys.
I'm hoping we start seeing (a minimum of 48k - wishful thinking) services in DAB+ on Now multiplexes as has already (just about) started on the MuxCo operations. As an example from my neck of the woods, stations such as More Sussex probably can't afford a traditional DAB slot on Now Sussex, but they might possibly be able to afford say a 40k DAB+ slot. Their stations as a whole cover a fair bit of mid / South East Sussex so would not necessarily benefit from a single or couple of mini muxes. |

You'd think that if small new niche entrants could find an audience anywhere in the UK it would be the capital. I wondered if it was because U.DAB were charging a premium 'London' price for carriage - but the fact that the stations on there are all in 128kbps stereo counters that. Nice to see DAB+ growing elsewhere though incl in Brighton. |

Yes its odd that all London stations are 128kbps in classic DAB.

Agreed. Particularly impressed with Manchester.
They are clearly doing something right. Packed mux with plenty of variety from the ILR to the community stations and new players. Guess that's a topic for another thread, however. |

![]() I have been thinking, if only one station had the guts (and the money) to boldly go with 96 kbit/s it would change the whole dynamic. It would make other music stations going out with 32 kbit/s look foolish. Don't get me wrong, I like the option of lower bitrates. I can definitely see LBC or Test Match Special using 24 kbit/s. A music station, however... |

I don't think anything will happen with the big boys or London, until the local radio rules have changed. There's space on D1 for global to launch its remaining stations nationally (and hopefully DAB+), but looks like they are holding back until changes have been agreed.

Thanks to Ofcom leaving matters to the market we've seen what others have called a race to the bottom in the technical quality of dab. We need more regulation not less.
https://twitter.com/TELEKO_DAB/statu...80562031390720 Minimum audio quality requirement of 48kbps using HE-AAC v2 and while it has only seven transmitters as a mandatory requirement (Slovenia is the size just slightly larger than South East England), its costs for a 64kbps DAB+ service would be approximately £16,000 a year. The laiseez-faire, free market libertarian way that Ofcom has gone is not working. Sadly, it'll be unlikely we'll see any re-implementation of quality thresholds - if anything, more abolition of rules and requirements. When we have small scale DAB multiplexes moving forward with developments (remember, they still have cost concerns as the big boys do) that the BBC or the commercial sector hasn't, its a concerning development. The fact that I made a big fuss out of a 64kbps DAB+ broadcast in the UK when DAB+ should be a good compromise between capacity costs and sound quality is concerning enough. |

Maybe one for a new thread, but at the World DAB General Assembly in Vienna, the rules governing the new DAB+ multiplex in Slovenia was displayed for delegates:

What you say is very interesting but I don't think the position is as gloomy as you believe. Muxco has already made some moves and whilst I have no inside knowledge I think the BBC, having been the pioneer of dab, will also. It's just a pity that Ofcom is unable to understand that when a small number of companies dominate a market standards have to be enforced.

I think MuxCo cocked up with DAB+. They set a precedent with 32kbps music stations that others have copied. It's too low if you ask me and it sounds pants.

I have to say the 64 kbit/s DAB+ is pretty decent sound. Unfortunately my dab+ dongal will not record dab+.
The 48kb is great, but trackstar station was down last night. I will get to hear more tomorrow, as I work north of the city and the trail reception is wide along the coast, but not very deep. |

just an update... all stations on the mux are now DAB+ bar juice FM. Gaydio has changed to 64k AAC Dab+

If you're broadcasting in HE-AAC v2, is there much benefit in going beyond 48k? It is optimised for lower bitrates.

http://www.radiomagonline.com/blogentry/1288 Using 64k means SBR can be used less to potentially provide a more natural sound above 13khz. Anyone in Brighton who can do listening tests? Interesting Juice (the mux operator) seems to be still using 192k standard DAB. |

I know people that want to get on the London small scale DAB multiplex but they just can't get any response out of U.DAB. Been waiting nearly a year now but nothing. Looks like the really progressive areas are Portsmouth, Birmingham and Manchester.

Depends. The effects of 32k with SBR and parametric stereo can be reduced by carefully using loudness levels,filtering and a bit of processing.

just spoken to my friend who is involved with the forthcoming launch of gaydio on FM in brighton and he said that the mux (bar juice) all went DAB+ due the mux owner. If they wanted to stay on DAB, they would have to pay extra. He was not sure the audio feed to the mux needs to be increased, as it the moment it sounds a bit metallic

How do the bitrates look at present?
With a bit of luck I'll be down there later today to listen in. |

If the transmission at 64k sounds metallic perhaps either removing the SBR component (going from v2 to v1) or reducing loudness as Jazz FM did might inprove the sound? |
