Usually the signal is the station ID, plus the artist and the song. If your radio can interpret the RDS protocol, it will display that information. It’s more common in newer radios, especially in cars. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
