Exploring our vintage radios

When I was asked to help develop ideas about early radio broadcasting for a proposed new gallery at the Science Museum I soon realised that I needed help to build up my knowledge quickly. I began with the usual resources – I read some books, looked online and scoured our collection for likely looking objects to explore. While all of these resources could provide me with a technical understanding of the history of radio, I struggled to get a grasp of what it must have felt like to have used early radio sets or listened to early broadcasts. It was time, I decided, to seek some expert help.

Several members of the British Vintage Wireless Society (BVWS) were already pencilled in to pay a visit to the Museum to look at the radios in our collection. It seemed like the perfect opportunity to recruit a few of them to work more closely with us. We knew we wanted to display one star object from the collection – the 2LO transmitter, which transmitted the very first BBC radio broadcasts in 1922. In addition we have a large collection of radio receivers from the 1920s and 1930s. What we were missing was a range of fascinating stories to help us choose between all those radios. We invited the members of the BVWS to help us select the stories that represented their experience and knowledge of vintage radios.

Five of the group offered their time, and I worked with a colleague to plan a series of four sessions for them. Over the course of the sessions the group got to know our collections and gradually built up their own set of criteria for selecting radio equipment. We asked them to arrive at a list of three objects each, meaning we would have a total of fifteen radio receivers as a long-list to work with.

As well as gathering a list of objects we were keen to collect stories about the historical impact of radios on everyday life. We also hoped to find out what led the members of the BVWS to be so enthusiastic about and enthralled with vintage radio equipment. They have a strong emotional attachment to these objects that would be brilliant to share with our visitors. We spent one of the four sessions at the British Vintage Wireless and Television Museum which holds an amazing collection of radios and televisions inside the walls of an innocent looking house in South London. While we were there, surrounded by all the fantastic objects in the museum, we interviewed some of the group and asked them about what got them collecting in the first place.

By the end of the four sessions we had a successfully arrived at a list of objects to display alongside the 2LO transmitter, together with stories to support them. One of the more unexpected items to make it onto the list was a ceramic mixing bowl selected by Lorne Clark. He told us how his mother, who had lived near a large transmitter, would place a pair of headphones in a mixing bowl in order to amplify the sound from a crystal radio set and make group listening possible.

The sessions were great fun and I certainly learned a lot about early radio from the group, and much more quickly and enjoyably than if I had been left to my own devices. Inviting outside groups to add their own expertise to the knowledge held by a museum and its curators can add a richness and variety to displays – especially as personal stories such as Lorne’s are often missing from a museum’s formal historic collections. Hopefully all of the BVWS members we worked with enjoyed their experience and gained an interesting insight into how a large museum goes about developing exhibition displays. I’m positive they enjoyed looking at our objects in storage because persuading them to leave the storeroom at the end of a session was always something of a challenge.

Our stormy Sun

August 24th, 2011 | by | astronomy, communication

Astronomers have announced that they can now track sunspots forming before the tell-tale dark spots reach the Sun’s surface.

The spots are caused by magnetic activity inside the Sun, and are associated with solar storms, massive bursts of material coming from our star. NASA recently released these staggering observations of our little blue planet being swamped by a sunstorm.

Better prediction of solar storms is vital to protect our communication, navigation and power systems. In 1859 the biggest solar storm on record zapped telegraph systems around the world, with some equipment even bursting into flames. Magnetic compasses went haywire. Aurorae lit up the sky. In today’s wired world, a big storm could be catastrophic.

In 1859, Richard Carrington observed a large group of sunspots, and two solar flares. The flares' path is marked A-C and B-D. This was one of the first observations of solar flares, which Carrington suspected were the cause of the disruption on Earth. (Science Museum)

Accurate space weather predictions would allow authorities to prevent the worst effects of a solar storm by taking satellites offline and shielding power grids. With changes in the Sun’s cycles of sunspot activity, this could become increasingly important over the next few decades.

Today’s solar weather forecasters are the latest in a long tradition of sunspot-spotters. Here are a few illustrations from our collections.

This X-ray map of the Sun's active regions was based on photographs taken from the Skylab space station in 1975 (NASA / Science & Society).

While solar weather can be troublesome, here’s hoping for sunny weather of a different sort for the last few weeks of school holidays. Once again, the Great British Summer has been a bit of a damp squib. Some things never change…

Celebrating Britain

May 3rd, 2011 | by | communication, events, medicine

May
03

The 3rd May marks the 60th anniversary of the Festival of Britain. The Festival celebrated the centenary of the Great Exhibition of 1851 at Crystal Palace as well as advances in British science, technology, manufacturing and art.

You won’t be surprised to hear that some of our objects were displayed there.

On first look, these fabric samples appear to be simple circular designs.

To the trained eye however, the pattern is based on the structure of haemoglobin produced by x-ray crystallography. Art, science and manufacturing collaborated on the design – it’s not just a fashionable fabric.

X-ray crystallography was an important tool for scientific discovery - the structures of DNA, penicillin and insulin were discovered in this way.

From one x-ray method to another. This piece of kit is known as a cine-radiography set specifically for the chest and lungs. Instead of taking still images, x-rays are taken in the form of moving film.

Although billed as a ‘technical progress of the British x-ray industry’ only two of these machines were ever made. This machine was developed in collaboration with Dr Russell J Reynolds (1880-1964).

Fans of the Science Museum will remember that the Centenary icon was the Russell Reynolds x-ray machine - his first one made at the tender age of just 15.

It’s not just show pieces that we have in the Science Museum’s collections. We also have memorabilia that could be bought by festival-goers.

Maybe you have your own piece of the Festival of Britain at home? Souvenirs were available to buy – much like in museums and galleries today.

Batteries not included

What’s the one gadget you couldn’t live without? Your mobile phone, PDA, music player, game console – or all those things combined in a sleek smartphone?

No matter which device you choose, the one thing that all these gadgets couldn’t exist without is their rechargeable battery - the beating heart of the modern world.

The first rechargeable battery was the Lead-Acid battery, invented in 1859 by Gaston Planté, but it was the Nickel Cadmium battery invented in 1899 by Waldemar Jungar that really paved the way for the future of mobile technology.

The very early mobile phones used Nickel Cadmium batteries, but the batteries were so enormous they had to be stored in the boot of a car. As demand increased improvements were made and soon you were able to carry your battery around with you in a handy carry case.

By 1983 the first stand alone mobile phone had been developed using the Nickel Cadmium battery the Motorola Dynamic Adaptive Total Area Coverage (DynaTAC 8000X). By 1989 they could even fit in your pocket – though it might have to be quite a large pocket.

Today the battery that probably powers the phone in your pocket and the laptop on your desk is a Lithium battery, most likely a Lithium-Ion battery.

Introduced in 1990 these batteries have emerged as the best energy to weight ratio, meaning they last longer but weigh less, and they have enabled mobile phones to become smaller and smarter.

The iUnit concept car in our Plasticity exhibition is proof that in the future lithium batteries could be used to power even more aspects of our mobile lives.

The year of the Rabbit

October 4th, 2010 | by | communication, computing

Whilst doing some research into the history of the mobile phone in Britain I made a discovery in the Museum’s collections that took me back in time. Back to when a pay phone was a useful piece of street furniture and the iPhone was but a twinkle in Steve Job’s eye.

The year - 1992.
The discovery - the Rabbit Phone.

The Rabbit Phone is a glitch in our technological past – a transitional invention that represented where technology was going, but not how the British public wanted to get there.

It was one of a number of telepoint services that were available between 1989 and 1994, that operated on the basis of a domestic cordless phone.

You could carry around your lightweight Rabbit Phone but it would only work when you were within 100-200 metres of a Rabbit base station, advertised by a friendly white and blue sign posted in windows and on walls. What added to the frustration was that these phones could only make calls whilst on the move. Not very practical…

Unsurprisingly the Rabbit Phone only attracted 10,000 subscribers and the network was closed on 31 December 1993. As a replacement, customers were offered an Orange mobile phone on the cellular network.

The Rabbit Phone could be considered one of history’s technological turkeys, but I choose to see the Rabbit Phone as a symbol of the mobile phone’s success rather than telepoint’s failure.

The rise and dominance of the mobile phone was so fast that it took everyone by surprise. Out of date before it was in proper use, the Science Museum’s Rabbit Phone is virtually unused.

Today telepoint’s legacy lives on, echoed in the wifi internet networks we now have in trains, cafes and bars.

As this recent article in The Guardian shows these hotspots are becoming an increasingly useful and important part of our daily lives.
