RE: VLF: Strong drifting carrier on VLF!

Starting hours seem to correspond to european working hours :o)

 

By the way, as an employee of a company developping, installing and maintaining high power VLF transmitters, I can say that such tests are very common on the air (for example, testing a new antenna array, assessing an antenna beam pattern, or anything else such as a qualifying a new set of variometres, etc)

Yes, and it's strong enough on the DK7FC grabber to see a samplerate alias, stepping down all the way to 18 kHz.

Yesterday Klaus DJ6LB near Nuernberg improvised a DF loop, and got approximately 70° / 250° azimuth. So Russian origin would be a possibility. Any other measurements available?

Kind regards,

Markus (DF6NM)

Hi,

The "staircase" continues today (2010-06-29) starting ~0630 utc at 23kHz, reaching 30kHz around 0730utc.
