Thanks Erik for the explanation.
I see, the observed behavior is expected and not a bug.

Frank,
? ?If your tinySA Ultra is less than 30 days old and was sold by a reputable seller, then I would contact the seller about exchanging the unit.? If you have owned the unit for more than 30 days and it only recently has stopped working properly then I would try the following troubleshooting steps.

1. Loosen the 4 screws on the back of the case and see if touch operation is restored.? The case on some version 4.5.1 units fit too tightly and if the screen mounting became slightly misaligned during use, the touchscreen would not work properly.? This same issue could also interfere with USB communications.? The tight case issue should have been solved on your version 4.5.1.1 unit unless you are just unlucky.

2. Completely remove the case and disconnect the battery for a few minutes.? Reconnect the battery and see if normal touch screen operation has returned with the case still removed.? Take normal ESD precautions while doing the above.

3. Check if the flexible cable connecting the display panel to the main board is properly seated.

? If the above trouble shooting steps don't solve your problem, then more extensive repairs are indicated and Erik or hugen may be able to give you additional suggestions.

Further analysis on my TinySA Ultra:

• This is an official (no clone) TinySA Ultra, HW version V0.4.5.1.1
• Device powers up, screen works.
• Can connect to serial port and enter 'version'.
• Can do 'clearconfig <passcode>' and 'reset'.
• On most other commands, the serial interface freezes, and I have to power cycle the device.
• The TinySA windows program connects to the serial port, but after the vbat command it times out:

• Serial commands like 'touchtest', 'touchcal', etc also seems to hang.
• I have succesfully installed the latest firmware using the ST32CubeProgrammer
• When I poweron the device while holding the 'rockwheel' to the left, it seems to change the frequency.
• When I poweron and then very quickly (within 0.5 seconds or so) press and hold the rockwheel , the menu displays, but after that the device seems to freeze up. The menu remains on the screen, but I cannot use the rockwheel to change anything and also the touchscreen is unresponsive.

Are schematics of the TinySA Ultra available, so I can troubleshoot myself?

The executables are stand-alone programmes and do not need an installed version of python.

For Linux, extract the two files inside QtTinySA.tar.gz into a folder, open a terminal in that folder and execute the programme by typing ./QtTinySA
There are other ways but this way is straightforward.
??
For Windows extract the two files inside QtTinySA.zip into a folder and run QtTinySA.exe by double-clicking it, or you can run it from the CMD window set to your folder.
The Windows executable works in Win-10 and Win-11 but not earlier versions.? It was built on Win-11.

There is a Wiki on GitHub: https://github.com/g4ixt/QtTinySA/wiki

In the "Release" section of his GitHub repository, Ian has a zip file (??) containing a stand-alone compiled executable. The executable usually bundles the Python interpreter, required modules and program into a single file so that a separate installation of python is not required.

I already have python 3.8 installed on all my computers, so I cannot personally verify Ian's executable does not require an already installed version of python.

Herb?

Thanks. gives me something to work with and thanks for all the work you have put into this.

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.

Herb

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...

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,

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.
