QtTinySA and tinySA-App are two entirely different software applications for the tinySA. If you downloaded and unachieved the? QtTinySA zip file, then running the QtTinySA.exe should get you up and running in Windows.??

I've never used Linux so if you are using that operating system and having issues then perhaps someone else can assist you.

Ian,
? Excellent contribution to the tinySA user community.? QtTinySA already exceeds a lot of the feature set of tinySA-App.? You should be aware that the VID/PID (0x0483/0x5740) is not unique to the tinySA and is shared also by the nanoVNA, tinyPFA and possibly other devices developed and manufactured by Erik/hugen.

? Also, if there is more than one tinySA in the user's system, for instance one as a signal generator and the other as a specan, then automatic identification of the specan unit may fail using the VID/PID.? If more than one device is detected with a VID/PID of 0x0483/0x5740, then the user should be given the option of choosing which one to use.? You could consider adding a menu option that allows the user to manually select or change the serial port.

? The time, effort and skill to develop and maintain a project like QtTinySA? is well beyond trivial.? Your efforts are greatly appreciated.

I have updated to v0.10.6 which adds some new features and fixes various bugs

v0.10.6
Fix Windows configuration database path bug. Windows users note: If previous versions were installed, your personal configuration database will be (for example): C:\Users\Clive\AppData\Local\QtTinySA\QtTinySA\QtTSAprefs.db
To keep it, move it up one level, i.e. to: C:\Users\Clive\AppData\Local\QtTinySA\QtTSAprefs.db

v0.10.5
File menu added with new features:
browse SD card, view bitmap screen captures and save files to PC
quit
Preferences menu new feature:
sync TinySA time to PC
Rationalised serial command encoding
Bugfixes for preset markers
Better control of displayed marker frequency precision
Removed requirement for newer version of "platformdirs" so it now works with the ancient 2.5.1 in Ubuntu 22.04 repo

This version is backwards-compatible with the v0.10.2 configuration database, but not with earlier versions.

Hi,

I just turned on my TinySA Ultra and noticed the touch screen is unresponsive. It does not respond to any touch input on the screen.

Also, the jog-wheel/switch (next to the power switch on the top) is unresponsive.

The unit powers up normally, the battery level is just over 4 volts.

What could be wrong?

Any help appreciated.

Desktop software is a weakest and strangest part of TinySA project in terms of UI.
Lot of skins but limited functionality...

Many amateur radio transceivers (and general coverage receivers) have reduced gain and sensitivity on frequencies below 1MHz.

This is in an attempt to reduce problems with strong LW & MW broadcasts stations overloading the RF stages and producing Inter Modulation Distortion (IMD) products that typically appear in and around the 160m amateur band.

Some modern SDR's such as Airspy products (and others), have very good sensitivity and better than average dynamic range, which allows decent reception on the lower frequencies.

Martin

I have confusion about the infulence of VBW, in my knowledge, according to the block diagram of the spectrum analyzer, when VBW > RBW, the bandwidth of VBW will great than the video signal(limited by RBW), so the video filter will not filter the video signal, then the change of VBW(still great than RBW) should not affect the smooth effect of the trace. But the actual display is not suitable for this guess, I think I must miss something about video filter.

? The VBW in the tinySA is implemented using a moving point average that simulates a RC filter.? It performs the same as the CONFIG->SAMPLE REP menu option, except the repetition samples and sweep times have been calibrated for each video bandwidth to approximate the equivalent performance of the selected VBW.

? The moving point average implementation of the VBW was the best solution Erik was able provide for anticipated users of the tinySA within the cost constraints of the original project.

What does this have to do with the Tinysa?
One needs to exercise critical judgement on the material on YouTube and to decide what is legitimate and what is not.

I have a 3586B and an 89441. Just above DC-32MHz on the first, with audio demod and super accurate signal level indicator,sensitive to about -120dBm with switchable narrow filters, and a just above DC -10MHz SpecAn on the second. Both are gobs more sensitive below 10KHz, or even 100KHz than any amateur radio transceiver I have ever used. Just because it will display the frequency does not mean it receives there, at least according to my HP and cheap Chinese signal generators.
I have played with a loop antenna some, but this thread has kindled a dormant interest again.?

?I learned how to be a brain surgeon by watching yootoob. I can now also fly a Boeing 777 if I had to.?

Not exactly portable but if you want to go diving into the weeds, try the HP-3561A. Not light at 33lbs but frequency would be hard to beat at 0.000125Hz to 100kHz. Pricey back in it's day at 12k$. Even has it's own tracking generator. No answer needed, just smile.

True, but there is an equal amount of false and erroneous information on YouTube. Personally, I would stay away from hobbyists made videos? and stay with the commercial outlets like Rohde, Agilent and others that know what they are talking about. Rohde has a very large library of videos showing how spectrum analyzers work.

I have heard it being called LoonTube since every loon can make a video, post it and 10000 lunatics will agree with them without questioning anything.

Again, this quick evaluation of RE from the TinySA - Ultras in no way, shape, or manner, intentional or unintentional, reflects anything to address regulatory RE levels.

? ?Actually, no need to imply anything regarding regulatory RE levels.? The sticker on the back of the tinySA Ultra shows that it is FCC and CE-mark compliant.

? Using a magnetic loop or e-field probe is helpful for troubleshooting emissions problems or perhaps comparing different samples, but as you cautioned, does not necessarily reflect regulatory radiated field levels.
