Re: Measure frequencies down to 500khz with tinysa?
¿ªÔÆÌåÓýDog gone it, you are right.? It could be 200 Mega cycles per minute.? Mea Culpa. ??On 10/4/24 1:43 PM, Mike N2MS via

Is there a way to collect the data from multiple displayed traces? You can use the "trace {# } value" console command to retrieve the values for each trace.??

For example, "trace 2 value" will return 450 values for trace 2 in dBm if the default units are dBm for the tinySA Ultra.? Example return format is as below, so you will need to parse out the data values.
?
trace 2 value 0 -89.4
trace 2 value 1 -89.6
...
trace 2 value 449 -89.1

Isn't it 200 Mc/s ?

Re: Measure frequencies down to 500khz with tinysa?
It is not difficult to build your own. I have built a number of loopstick antennas using ferrite rods. I chose the Amidon Associates R33-050-750 rods. I constructed these loops by placing a ferrite rod inside a piece of 0.5 inch pvc tubing slightly longer than the rod. I wrapped electrical tape around each end to center the rod in the tubing. Then I wound about 50 to 80 turns of wire (depending on the range I wanted) on the outside of the pvc tubing. I used some # 24 stranded wire stripped out of a length of CAT-5 cable for this. I brought the leads out to a capacitor, a 15 to 365 pF variable capacitor with any additional capacitance in parallel to cover the range needed. I used a NanoVNA to measure the inductance of the antenna I built at the frequency to be used, so I could calculate the approximate capacitance needed to tune to resonance. I have used such antennas in the range from 50 to 600 kHz. I found that they work quite well receiving WWVB and AM radio stations.

I have used both the TinySA and the Ultra at 90 kHz. I believe I have also used both to receive WWVB at 60 kHz. Zack W9SZ On Fri, Aug 30, 2024 at 12:06?AM Erik Kaashoek via <erik=[email protected]> wrote:

Because antennas with showing that frequency was suggested, and no one corrected that person, so I assumed those antennas could be used. |

I bought the moxon v2 915mhz, it's no better than the antenna that is included.

I bought the video aerial systems antenna just for fun, and it's actually way better, but still very little under 200 mhz. |

Hi @glradio,
this is from Windows APP which is in phase "work in progress" (as you previously asked question on my previous topic).

Erik,
thanks for answer.
I plan to collect some phones from my friends (those with different telecom mobile providers) and do scanning with TinySA Ultra and see where I get 'traffic' during? 'internet data big files upload/download' from their phones. I did it for my phone and I get specific traffic graph which is in line with my expected freq range and maybe after that add some screenshots to this topic just to share results of that experiment.
regards,
Toni

Re: #software QtTinySA v0.11.7 release

Ian, just an FYI Just ran a git pull and everything was updated and is working as expected on Fedora 40 (soon to be 41) Thanks! On Wed, Oct 2, 2024 at 1:58?PM Ian Jefferson via <ian.jefferson=[email protected]> wrote:

Re: #software QtTinySA v0.11.7 release

I have fixed the file browse/save bug and also the one where preferences didn't save unless a tinySA was connected.? For the avoidance of doubt, only .bmp files are displayed as images in the browsing window.? Other files can be saved by clicking on them and pressing the 'save' button.
?
v0.11.8 with an executable file that works with Ubuntu 24.04 & 22.04 and Debian v12, and a Windows executable are in the release.? The python sources and the config database are in the .

Re: Jason's question about releasing a Flatpack version, I expect it's possible but I am not going to try making one, nor for Docker or Snap, or similar.? But I am happy to consider other feature requests but please put them in the on Github.
