VLF up-converter

Yesterday I had an email saying the link to this page on my website was not working. It turned out this link was to my old site anyway, so I have corrected the link to point to the newer site.

See https://sites.google.com/view/g3xbm4/home/vlf/vlf-converter .

A reminder that this extremely unlikely to work with amateur VLF signals which need very narrow bandwidths and very accurate frequency. It is, however, suitable for general listening "down there".

    The new URL in your post also doesn’t work. It may be that you have a space between the slashes in the address?

    Regards,

      Thanks Keith. I had the last letter outside the URL by mistake. Corrected and should now work.
