Hello,

After considerable research I am now the proud owner of an ATU-10

When you see this device “in your hand” – it’s truly amazing - WELL DONE David!

?

I did not have the time nor my SMT workstation (microscope and all of the SMT rework tools) since at different QTH – so I chose what I hope was a reputable AliExpress supplier and ordered a fully assembled unit.

The “seller” was responsive and shipped the ATU-10 promptly.

I received the device yesterday – within 10 days – which is great and all for about AU$100 – which is great!

?

When I opened the package and held the ATU-10 in my hand – I could hear a loud rattle when moving the device up / down / and around – something definitely loose inside.

Quick look inside the case revealed a retaining “wire” for the OLED screen coming loose due to cold solder joint!

No big thing – easily fixed!

?

When powering the ATU-10 I could clearly see that the OLED text is shifted multiple pixels to the RHS of the OLED screen.

See the attached photos

?

Well, for a new device – presumably checked before shipping – this was disappointing.

(I still have not checked the full operation of the ATU-10 – its tune function – as I am still awaiting some components / cables, etc., before doing tests)

The ATU-10 was flashed with V1.4 firmware – presumably stock .HEX from GitHub?

?

I know that for the ATU-100 device there is a patch you can do with pickit3 software for the EEPROM - cell location 08 – whereby its possible to move the OLED pixels to the LEFT

?

Unfortunately, I don’t know if there is a similar PATCH which can be done for the ATU-10?

?

I don’t think so – because it uses different PIC and method of programming the firmware – much easier than using the pickit3

?

Anyway, I was wondering if anyone has experienced the OLED pixel shift with V1.4 firmware?

As in this moment in time I have no idea why the pixel shift is occurring?

It could be one of the following reasons;

?

1.?????? Bug in firmware

2.?????? Nonstandard firmware (unlikely – I think it’s from GitHub – since not many have $300 for compiler)

3.?????? Wrong OLED display OR Faulty (unlikely since all seems to work – except for the “shift”)

4.?????? Some other “construction” / assembly issues which caused this problem (Hmmm?)

?

Anyway, if its none of the above – I might have a real problem as it will be difficult to “fix” without either patching the firmware or having access to the compiler?

?

Hoping someone (maybe David can chime-in for a comment) might be able to throw some light to the above rather strange pixel shift for the OLED display.

?

One interesting thing is that the power off message is WAY OFF ( hi ) as the “F” is completely appearing on the LHS of the screen.

?

Any comments / suggestions are most welcome.

Hi Joe,


The same with me (AliExpress - Hisonauto) … but you‘re lost in space if you experience any trouble, have a look at my story:
/g/ATU100/topic/89736113
I endeavoured the ?dispute process‘ of AliExpress, and after some time Hisonauto agreed in my error report, but afterwards refused any further communication. There was no possibility to re-activate the dispute process contacting AliExpress once more.

<Well, for a new device – presumably checked before shipping ...>
Very optimistic! There is obviously no check at all before shipping … sloppy production seems to be not unusual. There are other similar experience reports in this forum.


Good luck!


You don’t need to have access to a compiler or some patching … just install firmware from Github. In your place first I would RE-install firmware 1.4, and possibly have a try with 1.3.
Flashing a new firmware works trouble-free within a few seconds. I did it several times … this is the only thing my device does well.
Attention: Have a look at /g/ATU100/topic/90081288

Thanks for the heads up - yes I did read you post - thank you.

I am one of the fortunate "buyers" who is fully aware of the pitfalls if and when making "faulty goods claims" on AliExpress (or eBay) - because I went through this some time ago with a seller who shipped me a device which was not same (specifications) as depicted on site. Needless to say - they said they will rectify this, BUT conveniently "stretched this out" to over 60 days - making any "claims virtually impossible.

Fortunately for me the seller was "honest" and did resolve the issue to my satisfaction - but simply took a long time.

I was lucky.

After this I learned about all the tricks that "bad" sellers use and if there is a potential problem I am always mindful to resolve any issues within the first 5 days - still giving me some options (and time) - if there is no progress.

My seller was not same as yours, I believe they are trying their best to resolve any issues - they said they will contact their supplier (the OEM I presume - who markets the SAME units to the majority of sellers) - to ask for their "fix" to this problem. I gave them 48 hours to get me some response.

If my unit checks out OK with operation (relays and function) - I can accept a faulty OLED screen - will simply replace the screen myself.
If the ATU-10 had other hardware problems - I will not be able to fix at the present QTH as don't have the appropriate tools nor time.

Hopefully this weekend will be able to do some in-depth testing.

Will report here.

Lets hope that all of the above information is useful for others who are using or are thinking of getting the ATU-10 and might have a problem.

Its a great device - I highly recommend getting one - a working one of cause - but just in case yours has a problem (like mine) all is not lost as the majority of the "sellers" are good and will resolve any problems - use the review system on AliExpress - if their scores are above average - you should have no problems.
