CLE Information

Co-ordinated Listening Events (or CLEs) take place several times a year and provide opportunities for listeners of all levels of experience to practice our hobby and learn more about it.

CLE 302

Dates: Starts at midday on Friday 22 March and ends at midday on Monday 25 March LOCAL TIMES at the receiver.
Scope: Please join us wherever you are - just log the NDBs you can identify in the range from 190.0 - 239.9 kHz plus all NDBs whose carrier frequencies are 'half-way' e.g. 267.5, 333.5, 386.5 kHz and any UNIDs you may come across in both ranges too.

If you wish, for this Event you can use only one Internet-based remote receiver to log signals.
