Adding RDS decoding to a vintage radio

[Edo] wrote in to show us how he added RDS decoding to a radio made in 1957. RDS or Radio Data System is a protocol for data transmission. This allows date, time, artist info, and more to be broadcast along with the music. Its a nice feature that many new cars come with from the factory. [Edo] wanted to add it to his old radio though. He kept the radio stock looking, choosing to use an external LCD to display the data. He has posted the information on where to splice in to add this unit to pretty much any FM radio as well as posting the schematics and source code for the unit itself. Look at the very bottom of the page for the download link, its a bit hidden with the advertisements.






Nice hack! Its a shame the UK government are planning to scrap FM radio broadcasts in favour of an as yet crappier digital setup! We must stand and fight for FM radio broadcast before it is to late!
On the other hand if they do scrap it then theres a large portion of unused bandwidth to play with.
