Re: How do people keep getting clones?

To be sure to buy a genuine tinySA have a look at the "where to buy" list:?
Look at the serial number at the back of your tinySA.
If the number starts with "AD" its a clone.

Erik
hi I would just like to echo Larry's comments, the TinySA is a brilliant piece of kit ...
?... I bought my TinySA from a UK supplier that was listed as a recommended? UK dealer - and I paid in full straight away, i.e. I purchased in good faith.?
As far as I can tell? my TinySA is genuine, the self tests run but I have not had to put it to any further tests, or upgrade firmware.
Erik,
I can understand your ire that 'non perfect' copies are infringing your intellectual copyright and tarnishing your Trademark, logo and reputation, but where do those who bought from a genuine source stand when the "genuine source", for one reason or another, drops of the list and our genuine items morph into clones?? The TinkSA price is a bargain and every Radio Amateur's dream come true but in relative terms it is still a significant amount for a home enthusiast to purchase, it is galling to think the investment made in good faith may become a piece of 'silicon' scrap.
I intended to buy a 2nd SA to use as a tracking generator and maybe the 'VNA as well, but where do I do my shopping?? If my 1st purchase transpires to be a clone what can I do ???
There ought to be a simple way for you to protect your products and the interests of those who purchase it.
Thank you for your efforts!

Many people buy first from the cheapest seller and only later inform themselves about the tinysA

Re: How do people keep getting clones?
#tinysa
I came here after being recommended ?to join the group in the QRPLabs groups as I was looking at getting a TinySA
?
Looking at the information about how to spot a fake, mainly by serial number I checked a couple of ebay stores and all seemed to show the real type of serial numbers in the photos of the product but I suspect they were fakes
?
I had a few issues with this relating to RTL-SDR¡¯s s well, the stores on ebay / amazon etc use images and information from the real deal its only when you get the device you find its a fake and a poor copy
?
The webstores are good at making the product look genuine without actually claiming it to be, so can¡¯t easily be prosecuted for misrepresentation
?
I have looked at the UK reseller recommended its about ?15 more expensive than the ¡°genuine¡± ebay ones, but I will pay the extra and get it from there, saves a lot of problems later down the line

Hello Erik,
Thank you for developing the tinySA.
You keep telling people where to buy an original. ?How the hell do some keep getting clones. ?Are the recommended dealers somehow receiving clones and then selling them as originals? ?You must be tired of answering questions about clones.
Thus, if the recommended dealers aren't selling clones, why do people keep asking for help when they must have NOT FOLLOWED YOUR ADVICE AS TO FROM WHOM TO BUY.
I love my 2 originals I bought from R&L. ?With all the questions about fake tinySAes, I worry that somehow I got a clone from R&L. ?Simply, if recommended dealers are selling originals, WHY ARE PEOPLE BUYING CLONES?
Thank you for your efforts! ? ? ? ? ?larry

Hi Larry. I bought my tinySA in the first shipment available from Zeenko (they had maybe 100 units available). I asked in another post about the graph, just to be able to compare the result with other equipment sold here in Brazil.?/g/tinysa/message/5481
Sellers claim to buy from official representatives, but with so many clones, it's hard to tell.?

Re: TinySA battery no longer charging
Try a different charger. I had some of the cheaper chargers stop working after a few month the cheap capacitors used wear out because they are marginal to start with. I actually build a small linear supply with a USB output for the TinySA. It solves the problem of switching noise radiated via the USB cable and gives me a reliable output voltage.?
I use a voltage /? data splitter to feed it when I use it with the computer. The splitter? can be bought at many places and is used for external hard drives, tablets and so on.

Re: What to do when a selftest don't fails
Erik. This is the result for my tinySA (first release). Is this the expected graphic for an original equipment??

Re: What to do when a selftest don't fails
Thanks, this confirms its a clone You will have, even after careful calibration at the target frequency, up to 5dB measurement error

The passing of the self test does not ensure if you will have accurate harmonics measurements when the tinySA has been made with wrong components as shown at the end of this video:?
Can you submit a picture of the screen after you did the following commands:
CONFIG/EXPERT CONFIG/MORE/BPF
and click on the screen to hide the menu.
You should see a wide peak centered around 10MHz

Re: What to do when a selftest don't fails
Thanks Erik for your quick response. Now my doubts are cleared. I will do the same as recommended by you.
Due to not so friendly relationships with India and China recently, getting the original tinySA from China has become complicated and not so economical. As confirmed by Maggie looks like you don't have any? recommended seller in India as of now. Maybe you can think of the same in coming days.
Regards? Anthony

Re: TinySA battery no longer charging
Try using a new USB-C cable, see if that helps. I've had loads of problems with the USB C cables wearing out quite quickly.
The cable may not be the cause of your particular problem but it certainly has been for me.
Barring that, I'd remove the board from it's case and make sure there is 5V coming from the USB cable with it plugged in, it should be around the PCB's USB-C socket somewhere.

Re: What to do when a selftest don't fails
Hi Erik, First let me thank you for creating this lovely equipment, looking at the size and functionality of this test equipment few years back it would had been science fiction :-) Coming back to subject line, yes I brought tinySA online where the online store assured they are selling original only and not clone. However, after receiving the product I feel it is a clone as the serial number start with "AD". The interesting part is that it came with valid software version and the noise level and attenuation looked good. To check I have upgraded the version to the latest version from your website and surprisingly it passed all the 12 tests, even the attenuation level test recommended? by you looks good. Now I am confused, should I be asking for refund for this device ? Attaching the pictures of the same:

TinySA battery no longer charging
I have a genuine TinySA purchased from the Zeenko store on AliExpress.
it worked fine when i go it, battery charged up OK, over 4 volts.
Now it will only charge to 3.27v and the red charging LED goes out before the battery is actually fully charged.
The display show the battery icon as almost empty.
If I plug in the USB cable again, the red charging light goes on, but will not stay on for very long.
Does anybody have any ideas on how to troubleshoot this problem?
Thanks for your suggestions.

I also noticed this error, even the error is in the adjustment of the LOW input and the HIGH input, but if you inform the calibration level exactly circa times, it will accept the correction in the fifth time.
|
Thanks, maybe something went wrong with the latest FW update. Let me check. --
