A multi-lingual balise 201 to communicate wirelessly with a railway vehicle, wherein the balise has a receiver 203 with a receiver loop 204 to a receive signal having first receive signal characteristics or second receive signal characteristics different to said first receive signal characteristics, a detector 206 configured provide an indication of whether the receive signal has the first or second receive signal characteristics, and a transmitter 207 having a transmitter loop 208 and being configured to transmit a first telegram in FSK operational mode or a second telegram in ASK operational mode, depending on receive signal characteristics. For FSK, the transmitter 207 has a variable capacitance 425 in a resonant circuit 209 and active feedback circuitry. For ASK the active feedback circuitry is decoupled by a short-circuiting that maintains a high Q value. Essential parts of the resonant circuit are shared for FSK and ASK.
