Editing the url slightly (www -> dl, remove the ? appendix) bypasses the cumbersome pre-download page:

Another option would be more turns on the primary and secondary (e.g. 3 and 36). The idea is that the primary inductance of the transformer should be (much) greater than that of the single-turn loop.

Hi Edgar,

Thanks, interesting pictures. What AL value do these ferrite cores have? Is it an FT80-77? Maybe the AL is to low, so you may get better results when using 3 of them in parallel, with the same number of turns, if you plan to use the loop on lower frequencies...
Is it intended as a portable equipment for experiments in quite locations? :-)

Hi Stefan,

Try this one.

Dropbox have "improved their service" by making the public folder private from March this year.

I am trying to learn how to share files and found that the link changed when the zip file was updated with the SL .usr file and the frequency file.
