Re: VLF: Strong drifting carrier on VLF!

[Roger Lapthorn <rogerlapthorn@gmail.com>]

This is why I was wondering if it was a signal generated by the HAARP system using non-linear ionospheric mixing. Two HF signals of sufficient strength could produce such a signal without needing VLF antennas at all. This has been done as part of the HAARP experiments before. 

BTW, exactly what is the HAARP system really about? Is the US trying to meddle with the weather, alter the course of global warming, or just thinking up another stupid way of wasting their taxpayers money on another defence initiative?

Dear LF,

 

The mystery signal starts at 12 kHz, and sweeps up to 23 kHz over a period of a few hours, which is nearly an octave. What sort of antenna system would be in use to allow that sort of frequency coverage? There must have been a lot of variometer twiddling and tap-changing going on!

this is curious... wish I was at home and could attempt to get a bearing. Paul's http://abelian.org/vlf/spectrum.shtml has directional loop spectra but unfortunately it hasn't updated since Jun 24. During the unid test transmissions, there were / are irregularities in the four-hourly schedule of JXN 16.4 kHz, but this may be coincidence.

 

Best 73,

Markus

Hi,

... and further up. Visible also at North Germany on all my
VLF/LF-monitors. That's one of those rare "staircases" which have been
observed up to 30 kHz in the past. Cannot do some RDF from where I am now.
