Hello Markus and group,
I will certainly look out for the signal. Only have to modify the
soundcard's input coupling capacitor a tiny bit, guess I must
connect a second capacitor in parallel. But sure there is something
suitable in the junk-box.
Are you, by chance, using a modified OAM antenna for transmission as
used by the German Navy near the danish border (see Peter's
article). If so, is the inner circle's rotation frequency equal to
the transmit frequency ?
Good luck and all the best,
Wolf .

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)
