Goodmayes Hospital Radio was founded in 1977 when it started broadcasting to the patients of Goodmayes Hospital. When King George Hospital was built it was taken under the wing of Goodmayes Hospital Radio and the station extended its reach to loads more listeners.

In 1999 our original broadcast studio was refurbished and fitted with new furniture and equipment and in 2004 we changed our on-air name to The Jumbo Sound, curiously the same name as the radio station in Holby City!

On June 25th 2006, The Jumbo Sound began broadcasting on the internet as a new means of reaching our, now somewhat disbanded, audience. This has been immensely successful and continues to be a brilliant means of drawing listeners to the station. 2006 also saw the appointment of our new president, Mr Richard Digance. In 2007 the station launched it's new blue and red logo and soon after launched the matching website ahead of the big anniversary celebrations. The anniversary was celebrated with special programmes, guests and appearances by old presenters. Later in the year President, Richard Digance, made a special live performance in the hospital social club to raise money for the radio.

Towards the end of 2007 we moved studios to a downstairs room offering us more space and better disabled access. In 2008 following a generous grant from our trust GHR had an entirely new studio fitted, offering better facilities for automated playout. This new equipment means we can have more scheduled programmes and even hourly news broadcasts. The digital playout system also gives presenters quick and easy access to thousands of songs which means we can easily accommodate requests.
