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.

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.

Hi,
I made a 1500W tuner according to the EU2AV scheme (PIC 16F1938 processor).
David N7DDC firmware based on old version 2.7.
Question for David,
is it possible to do it on software version 3.1 or 3.2 and display the correct power value?
Hex in the attachment.
