Dear LF,

 

in a joint project including a number of radio amateurs, our group is working on a large experimental earth-antenna system, which is able to radiate an ultra-low frequency signal at low power.

 

We are currently transmitting an unmodulated test carrier on 11.60576 µHz, and (according to our measurements) are achieving a radiated power of 16 microwatts. Frequency stability is on the order of 1e-8, which should enable narrow bandwidth observations with high sensitivity.

 

The transmission has been on air for a while. Any reception reports (especially of far-field detections) would be much appreciated.

 

Best 73,

Markus (DF6NM)
