Mal,

As M0BMU has demonstrated, a simple loop and preamp into a PC based VLF receiver such as SpectrumLab is able to receive stations as distant as DK7FC as long as the external noise floor around 8.97kHz  is low enough. 

Like many, I'm experimenting with such ideas with the intention of being able to listen/look for DX signals from people able to run decent TX powers and erect large TX antennas, not a luxury here in my tiny plot sadly. Nonetheless I intend to see what is possible despite my severe limitations. DX reports for me may be a few miles at best, but I hope to be able to give reports to others at considerable range.

For M0BMU's loop-preamp see my sub-9kHz webpage:

73s and hope to hear/see you on sub-9kHz in the autumn Mal!

Another hurdle the met office !!!! this time. How about another freq like 16 kHz. I cannot see how a few micro watts erp is going to effect the met office thunder and lightening Mega watt programme.
No one so far has responded to my message about RX capabilities on 9 kHz ie a suitable RX and proper antennas,  a requirement for long haul communications.
hundreds of miles not yards
