Re: Invitation: How high will your tinySA Ultra go?
(pertaining to TinySA Ultra non-+, type 405):
EXPERT CONFIG activates the expert configuration menu
HARMONIC sets the harmonic to use in harmonic mode. Leave at 3 unless you absolutely need to be able to see higher frequencies
The link EXPERT CONFIG takes me to:
HARMONIC does not appear here.
I would like to know the behavior of HARMONIC and it's settable range (the text above only suggests leave at 3; as I absolutely need to see higher frequencies, what range exists and what does this do?
Thanks!

Re: How to find this signal with all its harmonics
Why not use your TINYSA and a directional antenna to locate the source.? That should be the first step in alleviating RFI.? Even a 3 or 4-element Yagi on 70-cm is directional enough to find the source. ?

Thanks for your reply.
The red segment, is a quite loud signal, and from what i have seen is is spread over the 2m and 70cm band. And, we seem to see this signal not only in my house but also surrounding houses in a distance of more than 500 meters. What brings us to to a discussion i have with some other HAM'd. does someone make use of amplifiers whitout knowing what is gooing on on the bands. There are a lot of preppers and also hobbyists that like to see if they can strengten a signal without knowing the effects of it. The Red signal transmittion gives over the whole horizontal image a signal and i hink it is in fact "splatter"? over the a wide frequency area.? It is not harmonics but in this case that high energy it spreads way to far.?
?
What i am searcing for is :
1) Could i use TinyGS to make messurements to see how wide signal is "splattering"?
2) Am i able to make a recording into the TinyGS for lets say 2 hours since it comes in waves but not om a standard rithm.
3) From there is it possible to figure out, what type of device could make a transmittion at this frequency. I think the 2 meter band, where this is signal is verry visible should be such a signal, it is not lora, not an transmitter, it could be a type of packet radio signal, but, It seems to me a digital signal.
4) it could be interesting to figure out what kind of transmittion it is, like is it a lora signal, a wspr signal, a ft8 signal or packet signal, that makes it a smaller list of candidates.?
?
In my opinion, the signal strengt and the way it acts on the band is uncommon for CE signed devices. It should not be there, and it it better to find the source and solve the issue.?
?
We have a large transmittion tower i the area full with G5 and other ecquipmemt and maybe there is some sort of malfunction.
?
I can;t imagine this is a normal and acceptable signal, it harms the reception of NOAA, Meteor, Conversations, HAB signals and so on...
?
And i want to learn if it is possible to dril down to find the sources ... and maybe it is a misson impossible but, some guidance how to start would be a first step to a possible solution.?
?
As stated i am new, and learning, and want to learn, and if it is a sensor, i want to find it, and see how we can solve the issue?
?
I agree with you it points in the direction of a sensor (but on a frequency that is not common used for sensors as far as i know)? ... but it is one that does not comply to the regulations as fas as i know, and it is causing issues... for me as a ham ..? :-(?

in Windows the c:\Users\xxx\AppData\Local\QTtinySA\QtTSAprefs.db must be deleted
Replace the 'xxx' with your Windows user name.

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.

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.?

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.
