First anniversary of Portsmouth DAB minimux – Radio Stations Celebrate

Angel Radio’s Portsmouth DAB minimux today celebrates its first anniversary of full broadcasts. The minimux, a DAB multiplex licenced as part of an Ofcom trial to examine the viability of using low cost DAB transmission equipment and providing access to DAB for smaller services, launched on 19th August 2015. Since then, the minimux has grown from carrying six services to seventeen, with two more stations due to launch within the next few weeks.

The Portsmouth minimux has pushed the boundaries of what had been expected of the Ofcom trial by not only adding more services, but by also exploiting technology such as DAB+ and DAB slideshow. Angel Radio works with Hampshire based company Commtronix Ltd to provide transmission services and both organisations have provided consultancy to DAB minimuxes involved in the Ofcom trial in other areas of the UK.

Programming has also been important, with a wide variety of formats, niche and mainstream catered for. Twelve services feature some kind of Portsmouth targeted content, and thirteen services are broadcast in stereo, a record for a UK DAB multiplex. Originally a nine month trial, the licence has been extended by two more years to 18th May 2018, by which time it is hoped a permanent licencing regime will be in place for DAB minimuxes.

Tony Smith, founder of Angel Radio said:

“Over the past year, we have demonstrated that DAB digital radio broadcasting is a viable platform for broadcasting to smaller areas than traditional multiplexes, with lower overheads, resulting in broadcasters being able to transmit on DAB that might otherwise have been excluded. All the services on-air at the end of the original nine month licence term re-contracted with us for our extended licence term, and we see that as a resounding endorsement of our work in Portsmouth. The unsung hero of this project is Angel Radio’s Head of Digital Development, Ash Elford, who has worked tirelessly to ensure Portsmouth digital radio listeners are the best catered for in the whole of the UK”

Martin Kirby, founder of local classic rock station The Flash said:

“After being largely restricted to internet streaming for over 3 years and competing with thousands of other internet based stations, the option of affordable DAB broadcasts to our local area of Portsmouth came as a godsend to The Flash and has lifted our profile enormously. This experiment has not only opened up the airwaves for smaller, community based stations like ours, but has also delivered an incredible listener choice in the Portsmouth area. I firmly believe these small scale DAB broadcasts will be the tipping point for any radio fans still considering the purchase of a DAB radio, and I hope to be broadcasting this way for many years to come”.

Ian Walker, CEO of stations JACK and JACK 2 said:

“We are thrilled to be working with Angel Radio and having both of our award winning brands JACK and JACK 2 broadcasting across Portsmouth. We are also continuing to see month on month growth in streaming numbers across the region.”

Chris Stevens, founder of Chris Country said:

“We’re delighted to have Chris Country on air in Portsmouth. We get lots of positive feedback from the area, and along with our neighbouring stations on the multiplex, it’s great to be able to bring a previously unavailable format to the South Coast.”

A website at provides updates and information about the Portsmouth DAB minimux. It is also possible to follow the DAB minimux on Twitter and Facebook. The name Solent Wireless is used for public communications to avoid any misunderstanding that Angel Radio owns the services it broadcasts.

Quick facts:
17 services on air now – 10 DAB+ and 7 vanilla DAB
12 services featuring Portsmouth specific content
13 stereo services – more than any other UK DAB multiplex
14 services with DAB slideshow, with 3 more services expected to gain the feature soon

  1. Can you please inform Unforgettable Radio, in case they are still unaware of the problem, that there is every few minutes throughout most of the day, a silent gap of a few seconds in their transmission. It is very irritating to the listener.

    1. Hi Nick. We are aware of the issue with Unforgettable Radio and hope to resolve it soon. Thanks for your patience.
