I agree totally with Dave... I looked into this for a brief moment, and came to the conclusion that the tinySA is simply not sensitive enough for this task.

See:
https://www.nk7z.net/sdr-rfi-survey-p1/

Then see:
https://www.nk7z.net/tinysa/

The first link shows how an SDR can be used, the second link shows what the tinySA sees. The source on the tinySA is 20 over S9 here on my SDR... Massive difference in sensitivity and display ability.

73, and thanks,

I have one, and It's not very sensitive, so a preamp is required.  I think a portable receiver, directional antenna and a discerning ear are better tools.

Hi,
What do you think of TinySA as the main tool for RFI research in order to intervene effectively instead of a simple portable HF radio?

73!
