Any tests of the TinySAs will be posted on that dedicated site, not here.l

Take a visit to the McGeevy site.? The following should get you going:

There's also a link at the very bottom that is of interest.
We are addressing electromagnetic energy at AUDIO frequencies.? Some may even be detected by connecting a long wire or loop to the sound input to any PC or laptop.

A lot of my HF HAM radios work down there. But there specs aren't guaranteed. I've never tested them down there as well. But they go quite low. The next real problem is the antenna. For the SA or the HF receiver (30, 100kHz is not uncommon).

Too bad the TinySA is virtually deaf at these frequencies, but understandably; a highly sensitive and selective VLF/ULF receiver is oddly difficult (read "expen$ive) to create.
