Hi,
The difference is that the LCD is to show the
power value, e.g. 1500W, which probably will not be shown by the
version with the unadjusted program (for Flash).
This is what Yuri EU2AV suggested to me ... I found a
correspondence from 2020 ...
Secondly, I am not sure of the gear setting for correct Power
measurement and SWR in my version is 20 turns in the coupling
system.
All the time I would like David to speak on this matter and
dispel any doubts.
Regards ,

I can only think about the swr bridge being different with
the potentiometers. The pic controller adc is the same. I have
looked for alignment information but unfortunately.?
Instead the easiest alignment is to run full
power and measure the max voltage towards the adc. Depending
on the pic controller you need to adjust or 4 or 5 volt. I
don't remember the exact value unfortunately.
For the rest the circuit is exactly the same as
the atu-100. Just bigger components, larger PCB traces.?
I don't understand why the pic controller code
should be different. Except for the high power factor and
bridge coil turns.?
Hope you can find the information as eu2av
shared with you.
Best regards Onno

Hi Tim,
When it comes to the EE data, I can
make a copy of it, because I have worked out the
topic ... see the attachment.
But it's not just about EE, so EU2AV wrote to me
that there are even changes in Flash, I don't
remember what it was about, whether it was a power
measurement gear or something else, and that's why
it was done on version 2.7 because in version 3, x
broaks memory space.
That's why I'm asking, maybe David will suggest
something?

Hi Marek,
3.2 works fine in the ATU1000
BUT... Make a copy of the eeprom data 1st. ( this
is what I didn't do with mine and it took a while to
work out the cell values )
This is because the EU2AV version uses different L
& C for the tuner and you will also need to know
the turns ratio for cell 31 and check that cell 30
is set to 01. All that is in your eeprom data
When you update the s/w to 3.2 you will have to
input the cell data you copied from your old version
and write that to the PIC.
You can then do a read of the PIC to make sure that
all is as expected and then export that as a hex
file as a backup for just-in-case.

Hello Ellis,
How much output did/do You use in FT8 via the ATU-10, I think 5W is possible to much?

#ATU-10 VK3PE build complete.
#ATU-10
Hi, I have completed my build and made my first FT8 QSOs today.?
The battery life seems poor, but I may have managed to get low capacity batteries.? There are batteries available on eBay In the UK with wires attached, but they are non-rechargeable so be careful.? I chose to use AA battery holders to avoid soldering to the batteries.? This may give me problems using the case I have ordered.
I was worried about the usb socket shorting to the micro USB pins so I stuck a bit of Kapton tape to the socket before attaching.
My TP4056 boards did not have suitable capacitors (micro USB variety) or only 1 (USB C variety) do I had to order those.
I have no 220K resistors so R19 is two in series manhattan style.
Programming the PIC16F1454 in circuit using my picking required power from the USB.? ?A temporary wire from the 3.3v supply from the programmer to the chip gave me an over current error.
All in all I am very pleased and have another complete set so I will be building another.? A third will have to wait for more relays and mosfets.
I still have 12 spare PCBs if anyone in the UK is interested.? I have sent some to the EU and I am waiting to hear if they arrived OK and if VAT had to be paid.

Re: Chinese clones - not working as expected
#ATU-10
Hi David, yes I know the test firmware and it’s very helpful for checking relays. However can we have a special state to bypass all the inductors or capacitors? My understanding is with the current test firmware, if we switch between inductor and capacitor testings, there is always one inductor or capacitor activated and that interferes with VNA measurements on individual component. I’m thinking perhaps adding L0 and C0 in the loop to indicate bypassing all the inductors/capacitors. Thanks again for your great work! 73 de kn6pzo

Hi, All
Please notice that my GitHub contains a special test firmware. I hope it would be helpful in issues fixing.
