Amplitude modulation signalling system
In-game article clicks load inline without leaving the challenge.
The amplitude modulation signalling system (AMSS or the AM signalling system) is a digital system for adding low bit rate information to an analogue amplitude modulated broadcast signal in the same manner as the Radio Data System (RDS) for frequency modulated (FM) broadcast signals.
This system has been standardized in March 2006 by ETSI (TS 102 386) as an extension to the Digital Radio Mondiale (DRM) system.
Broadcasting
AMSS data are broadcast from the following transmitters:
- SW BBC World Service: 15.575 MHz

- LW RTL France: 234 kHz
