Other VLF Stations

For information, here are lists of other transmitters operating in the VLF or LF frequency range.
They usually cannot be used for SID monitoring: several transmitters could share the same frequency or a given transmitter could use several frequencies. Moreover, some of those satations are off air.


In order to get updates to those files, give Google Earth the link and not a local copy of the kml file.
