Re: Sensitivity?
Hmmm, don't have any traffic lights within a radius of close to a mile... Given the very significant difference in levels between my two antennae (both of which have a similar radiation pattern), I'm

Re: Sensitivity?
Hi Martin, Apart from the increased sensitivity the Ultra has a lot of features that make it a whole lot better than the basic Tiny, and having used both I'd say that it is definitely worth the

Re: Sensitivity?
Look into LED traffic lights. In the USA, the LEDs are in rows and a row or two can burn out while the light of that color is still usable. When some burn out the multiplexing scheme seems to start

Re: Sensitivity?
My tinySA shows a noise floor, for 3KHz BW 500KHz span, of -110dBm, S4, red trace. My T2FD antenna TD90 shows noise floor of -90dBm at quiet frequency and signals peaks of -55dBm. My vertical MALDOL?

Re: Sensitivity?
I'm not aware of any Teslas nearby. In any case, the RFI seems to be 24/7, so it would have to be a Tesla that is never actually used. Seems unlikely to be lights or solar power either - lights would

Re: #feature_request - its a great sign and endorsement #feature_request
Erik, its a very good sign that customer are clambering for extra features. It shows we love the product and want more. Consider if no-one was bothered, you would be hurt Take the positive from this,

Re: #feature_request #feature_request
Easy to build if you have: - space - power - money May I suggest you open your tinySA and try to find space for the 3 amplifiers stages required to get some dynamic range?. And try to find a component

Re: #feature_request #feature_request
If they are so easy to build, I would think it would not be a burden, and everything would be self-contained... regards Colin

Re: Sensitivity?
Hi Martin , you might look for a Tesla charging in the vicinity. I had some HF disturbance of off these in the past. kind Regards patrick

Re: Sensitivity?
I have a tiny SA and a TinySA Ultra, and I have also used them to try and track down noise sources. In my opinion the Tiny SA does not have sufficient sensitivity, for what you are proposing. As Erik

Re: Sensitivity?
The NF of the tinySA is 28dB so if you adding a cheap 30dB amplifier will be sufficient For inspiration: https://tinysa.org/wiki/pmwiki.php?n=Main.LNA The tinySA Ultra has an internal LNA with a 4dB

Sensitivity?
Hi all. first post from a new member... I have an RFI problem which is impacting on several HF bands and I'm trying to track down the source. Functionally, a tinySA looks like the right tool, but I'm

I understand, it's about a black number on a light background. The question is removed.

Re: Using TinySA with VMA TinySA
This problem was related to the regional decimal number formatting. The decimal number separator must be a dot and not a comma. Once I changed it, the frequency axis looked fine. Thanks to Vitor for

Re: #about_wiki #about_wiki
Thanks. Good remark. It's indeed maximum 290. But there is an option to select less sweep points -- For more info on the tinySA go to https://tinysa.org/wiki/

Re: #about_wiki #about_wiki
Better: " As the number of points displayed is 290, when the RBW is too small to cover...."

Hello, In the https://tinysa.org/wiki/pmwiki.php?n=Main.FREQ I read the phrase: The number of points scanned is *minimum* 290 but when the RBW ( https://tinysa.org/wiki/pmwiki.php?n=Main.RBW ) is too
