Within the early ‘90s, Sony launched one of the crucial distinctive moveable radios ever designed. However sadly, you received’t discover this retro-styled product at your native audio retailer. To be able to get your arms on this system, you’ll have to go to jail.
At any given second, greater than 12 million individuals are dwelling behind bars. For some, these stints are as little as a couple of days, however for an unfortunate group of people, time on the within is usually a lifelong sentence. With as little as one hour per day outdoors of their cells, the remaining hours of the day can really feel nearly everlasting. Whereas some flip to literature, meditation or train, an intensive variety of inmates have all the time turned to at least one common type of solitary enjoyment; listening to music.
And for over 20 years, inmates world wide have relied on one distinctive piece of musical gear to cross the time: the blandly named Sony SRF-39.
Initially designed in 1992, the SRF-39 was in contrast to the rest available on the market. Not purely as a result of it was created by Sony particularly for inmates – and by no means formally reached the business market – however for its distinctive design. Not like regular Walkmans, which had been coated in every little thing from glossy, phantom blacks proper by way of to vibrant canary yellows, the SRF-39 was fully clear. A very see-through outer shell gave customers (and, extra importantly, onlookers) a behind-the-scenes take a look at the essential but highly effective circuitry hidden inside.
Mounted beneath the thick casing was a murky brown circuit board coated in neon blue capacitors, a lime inexperienced headphone jack and a collection of difficult gray parts. On the high, tucked under a white Sony emblem, sat room for a single AA battery, an on/off swap, a skinny tuning knob and nothing extra.

Dissimilar to commercially accessible units, the SRF-39 had no place for a cassette tape or any third-party system. All for one good motive: security. It was believed that the less detachable elements inmates had entry to, the much less probability that objects resembling the cruel plastic outer casing of a cassette tape might be original into jail weapons. Furthermore, the design was democratic. No prisoner had entry to something roughly than some other prisoner, simply the AM/FM radio waves that they had been introduced with. Music couldn’t be stolen from different inmates or used as jail forex, and pressure might be largely prevented.
Jail wardens and guards additionally preferred the design. The clear housing and complicated design made it practically not possible to cover or carry undesirable objects like razor blades, needles, or contraband like medicine. And at a worth of $40 per unit – a overwhelming majority of a weekly spending restrict – it was unlikely that any inmate would danger damaging their largest connection to the surface world for a largely ineffective weapon. Whereas taking part in playing cards, exercising, writing, and studying had been nonetheless viable choices for inmates to cross the time, no different merchandise gave them entry to real-time information, contemporary dialog matters and music from the surface world.
Whereas numerous different fashions and types appeared within the jail market over the many years, the common-or-garden SRF-39 was all the time hailed because the gold commonplace of jail-house music units, not only for the prison-approved design, dependable nature or affordability, however for its uncooked energy.
These small but mighty bits of commercial design packed a punch, with customers throughout the west coast of america reportedly selecting up AM indicators from as far overseas as Japan and Korea. Thanks partially to an ingenious little bit of design that utilised an industrial-grade microchip alongside a single built-in circuit receiver, the SRF-39 may give inmates entry to audio beneath the heavy concrete partitions that fortified the jail with stunning ease. The simple, no-frills design additionally meant much less vitality was wasted, and a single battery may provide as much as greater than 40 hours of steady listening time.
In 2016, The SWLing Publish – a neighborhood of shortwave radio and beginner radio fanatics sharing shortwave radio evaluations and information – ran a marathon battery check on the SRF-39. Utilizing only one commonplace alkaline battery, the system may repeatedly run for 163 hours and 54 minutes, far outstripping trendy digital merchandise that hit jail cabinets in subsequent years.
Within the outdoors world, the dreaded ‘20% low battery’ warning on an iPhone can imply as little as attending to a charger throughout the coming hours. However the significance of battery life in jail can’t be underestimated; music units are relied on for extra than simply the act of really listening to music, and when batteries price cash, and cash doesn’t come rapidly or simply, the lifespan of a product that means that you can mentally escape is essential.
A research performed in 2007 at San Vittore jail in Milan discovered that “in a spot the place privateness is consistently denied, radio turns into a significant device for constructing and sustaining one’s non-public self”. Additional research have proven that inmates who interact in significant actions that hold their minds occupied whereas incarcerated, resembling listening to music, have fewer violent incidents and higher psychological well being and recidivism outcomes as soon as their time period of incarceration is full.
The straightforward act of listening to music whereas locked behind bars could be useful on quite a few ranges, from drowning out noise and rest to drawing a connection to the surface world and sparking necessary, emotional reminiscences.
In recent times, applications resembling Australia’s ‘Songbirds’ initiative and ‘Music For The Future’ have spawned across the globe, giving prisoners direct entry to music and devices throughout the jail, and lots of prisons have begun promoting various digital MP3 gamers at their services. Nevertheless, the Sony analog radio is much from lifeless, and the common-or-garden artwork of listening to music on a transportable radio behind bars stays robust, thanks partially to an unwritten code amongst inmates.
For a lot of locked on the within, it’s thought-about dangerous luck – and poor manners – for fellow inmates to take sensible, working, non-sentimental possessions into the surface world as soon as their time within the slammer is up. This cultural custom has helped the SRF-39 stay behind bars, even when their house owners haven’t, and has saved a overwhelming majority of those prized objects off websites like eBay and Craigslist.
So, whereas this unstated pact is the rationale that coming throughout a working mannequin within the outdoors world is turning into more durable and more durable for avid collectors, the shortage is an indication that someplace, in some unusual a part of the world, somebody in a lower than perfect scenario can pop of their headphones, drown out the noise and use music to flee the place they’ve discovered themselves in. Even when simply till the battery runs dry.
