Ooops, typo, must be ~/.config/QtTinySA/QtTSAprefs.db

I try to run QtTinySA v1.0.2. Command prompt screen pops up but nothing is running.
QtTinySA v0.11.7 is working fine. Windows 10 laptop.

I had the same.
When I deleted ~/home/config/QtTinySA/QtTSAprefs.db all worked again.

Re: TinySA Ultra Interval trigger still not working
Hi Don,
?
QI. So we meet again in another place ;) Seems I 'triggered' you to update the firmware.
?
Erik, I commented on a video of Don with the following:
?
'As far as I understand setting trigger to 'auto' does not trigger at all, it is normal SA mode. So you are taking snapshots of the signal 16.7 ms apart, but not synchronised. Hence the moving spikes. To trigger the signal to be stable you should select 'normal' and delay just above 16.7, let's say 20 ms. Yes, it will skip one spike, but the next spike will trigger at the same place. '
?
We had a little discussion about this but since there is no clear explanation on this feature in the WiKi any help/clarification from you would be helpfull.
(As for me: some help on the extended trigger feature to trigger on a trace would also be nice.)?
?
One of the things I noticed is that the sweeptime on the ultra is not constant: e.g. if I set the sweeptime to 50 ms the actual sweeptime in zero-span differs with every sweep +/- some ms. That would also explain Don's problem with the interval not giving a steady picture: every sweep has a slightly different time.
?
Regards to both,

TinySA Ultra Interval trigger still not working
Hi Erik,
?
Back in 2023 I reported that the Interval trigger feature you implemented for me on the TinySA was not working properly on the TinySA Ultra.? Today I upgraded the firmware on my TinySA Ultra to tinySA4_v1.4-196-g1e9c187.bin and I tested the Interval trigger feature again and it's still not working properly.
?
My test is to feed in a 60 or 120 Hz square wave (which is rich in harmonics) into the TinySA Ultra, set the TinySA Ultra to Zero Span mode with a frequency of 1.8 MHz, set the display sweep time to 20 msec, select interval trigger with a time of 16.66 msec and I should see spikes that are stationary (very little movement left or right) but I do not get stationary spikes on the TinySA Ultra whereas I do on the TinySA when doing this same test.
?
Sure would be nice to get this feature working properly on the TinySA Ultra as the TinySA Ultra has the built in LNA as well as expanded frequency coverage.
?
I'm sure your buried with the new TinySA Ultra Plus (congrats) but please put this on your to do list if possible.
?
Thanks,
Don (wd8dsb)??

Thanks for the quick response. Nothing to lose by trying so I'll give it a try and report back here. BTW, Nice drawings!
When the 3.5 mono jack is fully inserted, the jack groundline shorts the connector's R-channel with the connector's ground. Since R and L are internally linked in the #Ultra, the audio signal is grounded.
To be able to hear with a mono jack the solution is not to insert the jack completely

I have updated the PC App to
Note:? Any existing config database QtTSAprefs.db must be updated, it's not backwards-compatible.
?
Updated with improvements and new features. See the for details of how features work and how to update the database.
??
New:
Waterfall display.
Save sweep data to a CSV file continuously.
Github workflow now builds the executables for Linux, Windows and macOS directly in Github runners.
??
Improved:
Any marker can be associated with any trace.
Marker max/min tracking much improved and now with 9 levels.
All markers can have a delta marker.
Peak detection threshold and frequency boundary lines de-cluttered.
All Python files moved into 'src' folder.
?
Please report any or start on the Github pages , not here.? It would be interesting to know on here if the macOS executable works ok since I can't test it.
?
Thank you to Clive, Bill, povnz and xros for testing and contribution of ideas.

Re: How to find this signal with all its harmonics
These are signals in the ISM band. The horizontal bar is a nearby (outdoor?) sensor. They are very wideband and pita for shure.?
These signals are very common in urban surroundings..

Re: How to find this signal with all its harmonics
Hi,
If you mean the short horizontal bar, that looks like noise just increased briefly on entire band. It's difficult to say what that is.
But if you're talking about the vertical lines visible in equal spacing and one is zoomed on subsequent picture. That to me looks like an inverter or a switch mode power supply. Probably a rather small one to cover 2m (or it has wiring that happens to favour that band).
The tiny telescopic antenna should be good enough to pick that up if it comes from your house. Just walk around and try to find it. I'd set a fast scan rate and maybe max hold. Go into a room, max hold for 60s, see how bad is it. Go into the next room. And so on.
As for specific frequency you gave to experiment. Sometimes it is better to set very wide to see few MHz. Sometimes it's better to zoom in on one line.
Mind they may drift in frequency as the device heats up/cools down or the load on it changes.

An approach, or point out documents and or youtube recordings that could help me are welcome. in the filename is de date and time, it seems the issue is every 10 minutes but i am not 100% sure, this is also something i would like to learn if i could make a recording of the spectrum and that way find the spikes in time.?

Thanks for your suggestions?

That was Digikey not digital.
Darn word correction. I hate a phone that tries to think ahead for you!

Re: TinySA ULTRA LEVEL CAL -> Signal Level incorrect

It is available in several places on the net.
Just google for?BGA2817 to see if threr is any place near you.
Mouser or digital for two.

My Android smart phone has?that feature. You can zoom/enlarge the screen image by spreading two fingers on the screen. Is this possible with TinySA in the future?

Re: Invitation: How high will your tinySA Ultra go?
I know mine goes at least to 12 GHz in Ultra mode because I've used it to peak up 12 GHz sources.
Zack W9SZ
Here are the specifications for the Ultra:
Spectrum Analyzer spec:
- Input frequency range from 100kHz to 800MHz (900 MHz for
Ultra+) in normal mode and up to 6GHz ( 7.3GHz for ZS407 ) with ULTRA
mode enabled
Here is a screen shot of both my TINYSAs: ??????  If this email doesn't support embedded imagery, I'll also attach it.
I just tried mine and the maximum settable frequency displays 12.072 GHz.? I tested it at 11.6 GHz and it still registers.?
Is the "Kernal" you are inquiring about?? If so, mine is 4.0.0 - not what you are inquiring about.
Dave - W?LEV
Erik, Isidro,
Returning to old thread. In my recent post #19273 I asked the same question, and this discussion (starting at #8369) is basically identical, so as I read the discussion here, I remain particularly interested in usability (with compromised limitations) in the 5-18 GHz range on the original TinySA Ultra.
I am interested in the result of any test along lines of what Erik suggested in #8485 (at least up to 18 GHz), particularly for the original TinySA Ultra (405) version.
Thank you!
