Andy, The error is: "-d dev/ttyACM0", must be "-d /dev/ttyACM0" But no need to use the -d unless your device is at an unusual port, e.g. on a mac. Just use: sudo python3 nanovna_remote.py -z2 What's

Thanks Isidrio - but they are quoting the same delivery date as my local supplier... Martin G8FXC

I have installed this script, but I think that I am not specifying the comport correctly. My attempt to list ports gives this: dmesg | grep tty [??? 0.112805] printk: console [tty0] enabled [??

Hi, youcan look in the eleshop.eu They are aprooved seller, I have ordered my TinySAs and my Ultra from them. Good seller for my personal experience. All the Best, Isidro ?BlueMail for Android

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

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

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

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?

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

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,

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

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

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

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

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

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

Wiki part on markers is updated as the text was wrong -- For more info on the tinySA go to https://tinysa.org/wiki/

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

Hello, Here: https://tinysa.org/wiki/pmwiki.php?n=Main.MARKER I can't understand phrase: "One marker is active and marked with an inverted number." I have never seen inverted numbers on a marker. In

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
