Hi Markus,

Another thing that appears strange to me, if these signals should have come from the Alpha transmitters: On the TF3HZ grabber you can clearly see that the "strange" transmissions have been significantly stronger than the Alphas! Visible by color... Ant the traces of RSDN-20 haven't become darker turing these times...?

HW?

Hi Stefan,
 
three of the frequencies seem to be the alternate frequency set of the Alpha (RSDN 20) navaids, mentioned on
 
F6  12500.00000  Hz = 16 x 781.25 Hz
F7  13281.25000  Hz = 17 x 781.25 Hz
F8  15625.00000  Hz = 20 x 781.25 Hz
 
There also seems to be another one somewhere around 12.75 kHz.
Best regards,
Markus (DF6NM)

Betreff: VLF: strange transmissions

VLF,

There are strange transmissions near 12.4, 13.3 and 15.6 kHz, narrow 
band, very strong here in Heidelberg 
http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber.html and 
also in Iceland 
http://simnet.is/halldorgudmunds/TF3HZ_VLFgrabber/index.html, also very 
clear at http://www.ok2bvg.cz/vlfgrabber/ and others.

Does anybody know what it is? Looks different to the often seen 
staircases during transmitter tests...

Unfortunately many VLF grabbers are paused / OFF these times...

73, Stefan/DK7FC
