The following list has been collated from various sources. Where I have more details and/or heard/saw the station, clicking on the entry will bring up the details/log. The list may include non-operational stations or frequencies that have been allocated but not used. If you have any information to add please let me know so that I can keep the list up to date.
Frequencies below 10 kHz are not allocated by the ITU, but there are
a number of transmissions below these frequencies. However I cannot confirm
any at present, still working on it. For a good source of information see
Rennato Romero's web page: http://www.vlf.it
