Radio Text:

Some European broadcasting organizations have introduced, or are introducing, an improved version of the Radio Teletext service inaugurated in the United Kingdom by a number of commercial radio stations in the late 1980s. Like the UK Radio teletext service, RadioText is separate from, but in addition to, RDS (Radio Data Services). The RadioText data are carried on a 76 kHz sub-carrier (UK Radio teletext: 69 kHz), FM (FSK) modulated at 16 Kbit/s (UK: 5 Kbit/s) with the FM carrier deviated by ±5.5 kHz (UK: ±7.5 kHz). Sony has designed a receiver, Textman, specially for the reception of the RadioText service.
