VLF transmissions (10 - 150 kHz)

This web page is just another view of the content of www.mwlist.org, a unique database of worldwide radio stations on VLF, LW, MW and SW. MWLIST powers various things like the mediumwave section of fmscan.org, the mwoffsets file, a userlist for Perseus, and an online logbook site. Such a global database did not exist before. It was created following the example of FMLIST. It is a non-commercial and hobby project and open for everyone to contribute and use. We understand that maintaining the database is time-consuming for a single person, but may be practical for a team of dedicated users from all over the world. We are inviting everyone interested to join and to make this database a useful tool for all DXers and radio enthusiasts.
