[RFI] TinySA as an RFI research tool

[Lee STRAHAN]

Hi All again,
   While I am thinking of it I also tried the little radio called a Malachite. It suffers the same problems but is a bit more sensitive than the TinySA. One of these with some sort of antenna and preamp looks to me like it would be pretty good. Neither of the two TinySA or Malachite worked as well as the Tecsun PL660 without externals.
  Just my 2 cents worth.

Hugo and all,
      I have looked at and tried the TinySA as an interference testing tool. The sensitivity of the Tiny Sa only goes down to -100 dBm. I was thinking at some point I would add a 20 dB preamp and try it again. As it is by itself with the short vertical it is not sensitive enough to pick up much RFI. I specifically am referring to 40, 80, and 160 meters. I did not try it on VHF with a small beam. In addition, the small vertical antenna supplied with the TinySA swings freely on its connector and will not stay vertical or horizontal.

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?
