Sessions from Monday, 30th November 2020 – virtual event

Stay tuned for weekly videos from Radio TechCon 2020…

Watt now? Watt if? The Hidden Power of Radio

There are various studies investigating the environmental impact of digital technology and services, but limited research dedicated to radio broadcast and listening. With changes to the radio industry on the horizon, such as a potential digital switchover or greater uptake of internet-connected devices, it’s important we understand how both industry and consumer decisions could impact the environment.

In this session, Chloe Fletcher from BBC R&D will explore how much energy is currently needed to prepare, distribute and consume BBC radio services, and how this may change over the next 20 years.


The Multitrack Audio Fellowship helps people from under-represented backgrounds find paid internships within the radio industry. In this session, Lisa Hack gives a brief introduction to the scheme and explains how technology teams can help.

Pencadlys BBC Cymru Wales

Building a new broadcasting centre from scratch is a huge project which can span years. So how do engineers, project managers and production users work together on complex projects, and what lessons can be learned for the future?

In this session, Lead Architect Mark Patrick and Producer Sharif Shahwan take you behind-the-scenes of the BBC’s new Cardiff HQ, and share tips on how to get the most out of your project team (and vice-versa).

If you have considered a shift to a career in major projects engineering, this is for you!

A Face(book) for Radio: VR sound and audio innovation

Broaden your (Facebook) Horizons – VR has been the ‘almost there’ technology for years, but under the bonnet, audio is the key to its success. In this session, Caleb Epps from Facebook Horizon’s Sound design team, explains how VR audio works, and how the technology can be used in the wider audio world – including at your radio station.

Hey Beeb!

The story behind the BBC’s ‘Beeb’ voice assistant, how it works, why it’s not competing with Google and Amazon… and why it can speak in different accents. Head of Product Andy Webb introduces Auntie’s new voice.

Don’t Mux It Up

Are you a bit hazy on SId Codes? Not sure how to troubleshoot a weird character appearing on your station’s DLS display? In this session, Ash Elford will give you a whistle-stop tour of the basics every engineer needs to know about making their radio station look good on DAB.

Times Radio: Plandemic B

Launching a new speech radio station on a tight deadline is tough. Where are the studios going to be? How will the staff be trained? Are there enough supplies of tea and gaffer tape? Times Radio had to cope with all of these challenges – and then along came Covid-19.

One year on from the launch, take a look back with Lead Stations Engineer Chris Thame to find out how the team managed to get on air whilst staying 2m apart.

It Is Rocket Science – How NASA Does Sound

NASA broadcasts thousands of hours of televised and internet-streamed content from space. But what is happening behind-the-scenes? How does the world get to hear the instructions for ground control, and who teaches the astronauts how to use a microphone? NASA’s Emmy Award-winning sound engineer Alexandria Perryman reveals all.

The Internet Monkey Cage

The pandemic has affected all of our workflows, as staying at home became the new going out. But how does that work when you normally have lots of guests in a studio …or need to record an audience laughing in real time?

The BBC’s Matthew Page tells the story behind its Pre Rec and Virtual Audience systems, with a special guest contribution from Robin Ince from the Infinite Monkey Cage.


The ability to display station names, programme types and dynamic text is very much part of the appeal of DAB and DRM as a modern digital radio technology, but if they are going to become truly global and ubiquitous, then they will need to be fluent in more than Latin script.

The BBC’s Abdallah al-Salmi explains the complexities of Arabic script display and how the ETSI standards of DAB and DRM have been updated in order to support the growing requirements of broadcasters across the world.

Freelance Your Future

The last couple of years have seen huge changes in our industry. Many people have been made redundant, and others have found new ways of working due to the pandemic.

Whether you are freelance, employed or thinking about making the leap, discover what you need to help you make sound financial foundations today and to deliver on your goals tomorrow.

In this session, financial planner Emily Man looks at the practical, legal and financial things you need to consider if you become self-employed – and what you need to know if you are hiring freelance talent. This session could change your financial life!
