Onderwerp: VLF: Strong drifting carrier on VLF!

Dear group,

Currently there is a very strong (abt 30 dB S/N) drifting carrier that started about 7:30 UTC on abt 12 kHz and is moving now up on 14 kHz. First i thought that it is a local signal but now i saw that it is also visible on the DF6NM VLF grabber with about same strength!

Has anyone an idea what it might be? It must be a commercial transmitter due to the signal strength at both locations!
