[RFI] TinySA as an RFI research tool (score: 1): Author: Hugo Loranger <ve2_ugo@hotmail.com>; Date: Thu, 17 Jun 2021 02:56:39 +0000; 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!

Re: [RFI] TinySA as an RFI research tool (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Wed, 16 Jun 2021 20:16:33 -0700; Spectrum analyzers and spectrum/waterfalls built into radios are very useful tools, but not if equipment needed to run them are noisy. These two docs list some, also some good battery operated radios; /archives//html/RFI/2021-06/msg00049.html (8,583 bytes)

I think a portable receiver, directional antenna and a discerning ear are better tools. Dave Hachadorian, K6LL Yuma, AZ Hi, What do y; /archives//html/RFI/2021-06/msg00050.html (8,289 bytes)

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; /archives//html/RFI/2021-06/msg00051.html (8,742 bytes)

It suffers the same problems but is a bit more sensitive than the TinySA. One of these with some sort of ante; /archives//html/RFI/2021-06/msg00052.html (9,784 bytes)

When you get out in the field tracking down a noise, you will encounter many noise sources. You don't want; /archives//html/RFI/2021-06/msg00054.html (12,149 bytes)

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

I have to try that. I guess I am lucky... For some reason, (I know not why), I have been able to match RFI sour; /archives//html/RFI/2021-06/msg00057.html (11,855 bytes)

They came without a built-in preamp and the noise figure was typically 18 to 22 dB. They needed a preamp, external. E; /archives//html/RFI/2021-06/msg00058.html (8,912 bytes)
