Looks good

Greetings, Eric:

Going through the thread, I would like to think my purchase via Amazon.ca is a genuine article. Would you please check?
Also trying to figure out the firmware details.
The presentation case appears legit, as per a previous poster's photo.
I am enclosing pictures.? If you wish, please delete images, so you can keep the security intact.? The board colour isn't quite as described, so that raised a flag.

Thank you!

This is a clone, but the USB driver has nothing to do with whether it is a clone or not. The USB-CDC serial port can be correctly identified without installing a driver on a fully installed Windows 10 operating system, unless their USB port is installed incorrectly.

Erik, thanks for the reply!

Oh yes, it says 'HICH' on the front and not 'HIGH' :-(

Sorry, will check at Zeenko Store on Aliexpress -
up until mid of this year, there is no customs & VAT charge... hopefully!

Seller Toolbox-store is known to have sold at least one clone.
Can you post a picture of the front and back of the tinySA?

Hi all,

received my tinySA today (Aliexpress Toolbox-Store). Since some buyers
reported in this shop: 'no clone' I did risk it, because it was delivered within
~ 1 week from Czech Republic to Austria (without customs control, inside the EU)

- delivered in a dark brown box with golden print, tinySA in molded PVC
- cables + antenna etc. included
- sticker on the back of the tinySA looks OK (?)
- self test is OK !
VERSION:
- tinySA v0.3
- version tinySA_v1.1-66-g2015f17
- build time: Dec 27 2020 22:01:49

- internal shields are perfectly soldered
- device itself does what is supposed to do, via touch screen

but - on 2 differnt Win 7 PC and one Win 10 PC, on all of them, it says 'unknown USB device'.
Did the suggested procedure as on tinysa.org 'PC Control' but none of my PC recognized the
serial USB. Installed the drivers of en.stsw-stm32080.zip - no change, USB is not recognized.
Since there is no com port, I can not use the PC software or try to upgrade firmware.

any ideas please ?

greetings
Wolfgang

Erik, please don't think too technically:?I have no idea about how TinySA is designed so I didn't know that its flash memory is so limited. Since other instruments do that, I just asked if it's possible because it could make it more convenient.?I didn't propose any extra HW. The proper reply should be "No possible because? he amount its flash memory is limited".

No, it is a good way to get back to a fixed starting point and reset any forgotten settings.
If you want to restore a set up save it in one of the memories ther for that purpose.

The minimum frequency resolution of the output is, depending on the frequency, 156Hz or 312Hz,?50Hz steps are not possible.

FM only, so yes should be fine

I didn't think you were criticizing the design, Ian, sorry if I came across that way.? I just figured 50 Hz would be close enough for normal testing.? Certainly for AM and FM CB signals, and for SSB units, I imagine they have a receiver fine tuning control?

Hi Jim,

Its not a criticism of the design, just an enquiry

Ian?

if I input 27.79125 I get 27.7913

And that's not close enough?

Thanks Erik,

So i guess the step size is too small, if I input 27.79125 I get 27.7913

Just wondering what this has to do with the TinySA????
KC7BJE CLYDE?

It's not possible to define a channel setup.

Loving the TinySA, a great piece of gear which I'm using more and more.
Just wondered,? UK CB use an odd frequency range. 40 chanels from 27.60125MHz to 27.99125MHz in 10KHz sreps. Is there a workaround to selecting these frequencies on the TinySA?

Regards
Ian

I do not agree
The amount of writes to the flash memory is limited so you do not want to write without need.
The PRESET/STORE/STORE AS STARTUP is there if you want to start with certain settings.

Please do not propose extra HW to be added, the design goal was the lowest possible price for a balanced set of functions.

Hi. Every time the TinySA is switched on, it doesn't remember its previous state and starts with the default factory parameters (e.g. Low band, Frequency from?0.1MHz to 350MHz, auto mode, etc). In my opinion it should restore the same conditions I set when I have switched it off. Do you agree?

New FW release
Version v1.1-85

Changes:
- Battery indicator added to output menu
- Attenuation will decrease when auto attenuation is on and no maximum is found.

The second change solves the problem where no signal is visible when attenuation is at maximum and the tinySA refuses to automatically decrease attenuation because it does not see any signal.
