Europäische Funk-Rundsteuerung (EFR) Teleswitch (European Radio Ripple Control GmbH (ERA) Teleswitch) is an energy management system operated via long-wave radio. The system is deployed by European Radio Ripple Control GmbH.

Uses two transmitters in Germany and one in Hungary, covering most of Central Europe. Also known by DCF39, DCF49 and HGA22, the transmitters in the network.

Uses FSKFrequency-Shift Keying modulation with 170 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). shift at 200 bpsBits per second (bps) ASCII
