Interestingly,
my on 8270.0025 Hz carrier transmissions during the last three evenings
Jan 20, 18:00 - 23:00 UT,
Jan 21, 15:28 - 23:00 UT,
Jan 22, 13:23 - 23:00 UT
left three dots on Stefan's 47 uHz spectrogram
http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html .
This is astonishing because the tree-receiver is currently connected
to a north-south oriented loop, whereas I am due east in a null. So I
was wondering whether reception was made possible by skywave with
rotated polarisation? Perhaps reminiscent of the playful colour changes
on Stefan's MF colour-DF grabber.
Despite much lower noise background, the (shorter) daytime carrier
Jan 22, 07:00 - 10:00 UT.
left no trace at all.
