The two lowest VLF frequencies in use are apparently:
- 11.904 kHz RSDN-20 network, a Russian navigation VLF system with transmitters located in Novosibirsk, Krasnodar, etc
- 82 Hz ZEVS system, an ELF transmitter located on the Kola peninsula and dedicated to strategic transmissions to Russian nuclear submarines.
Jean-Louis F6AGR receives both stations near Paris with an E-field receiver consisting of a home-brew receiver fitted with a FET/BJT front end and a 1m long cylinder vertical antenna.
