What is RDS?
RDS is data broadcast on a subcarrier of an FM signal. It is an internationally agreed standard, and is used worldwide. RDS's features include PS Name an 8 digit alphanumeric label of programme service, PI Code to allow automatic retuning of the radio if the signal strength deteriorates, and RadioText extended text display sometimes used to show record name and artist.
How is RDS useful to a dx-er?
Even brief bursts of a distant signal can contain sufficient readable RDS data for that signal to be identified. So for any propagation mode, being able to monitor and decode RDS data is an invaluble tool for an FM dx-er. Using a PC to continously log incoming RDS data is an additional asset.
RDS Listings
I have compiled RDS listings for UK radio stations. (Links on the right). I have also included links to other sources of data. My listings are as accurate as possible, but stations do change their RDS names, and new stations are coming on air all the time. If you have new information then please with your updates.
