Hi All
New firmware for ATU-10 with better power and SWR calculation for your test.

Thanks?G8GYW for the idea.

I was just wondering if there was an update. Once it’s confirmed working could you create a version where it doesn’t shut off? (I operate a lot remote away from the radio). ?It’s been working great!

What is the timeout set to on this one? I shut off the IC-705 it was plugged into and came back maybe an hour later to tint the ATU was still on. Outside of that, 1.6 is working great.?

There’s a version of 1.5 with no timeout. I didn’t think that the 705 would wake it back up after an extended time. Mine is always powered via the USB cable.?

Thanks to all, this WF just for the test, I wanna add some things before releasing.
Most likely this FW is Always On version with 0 timing set. Not a bug, it is future.?

I am aware that there is a hardware and software "hack" that will allow the Tuner to operate at QRP levels.? Is it possible to incorporate the software changes into an official QRP version.

Thank you

Hi, Francis.
I think are you talking about ATU-100 tuner.
ATU-10 is a different one and works above 1 Watt independent to FW version.?

Sorry, I "dropped" a 0 when reading the thread.? I will look more closely at the ATU-10.? Seems like it might work for my application.

Thank you.

Francis, the firmware version for ATU-100 is staying the same, to change needed parameters you have to set some memory cells before? flashing processor. No any sense to do specific FW . Read the manual at the end, cells description, you will find many interesting for you .?

hi.
Next iteration for FW 1.6
10 cells for tuning you can find by address EEE0?



It was opened in Notepad++ as Intel HEX file.
1) Time to display off in minutes, 5, 0 to always on
2) time to power off in minutes, 30, 0 to always on
3) rela's delay in ms, 8
4) min power to start tuning in ten's parts, 10 (1.0 W)
5) max power to start tuning in watts, 15
6) Delta SWR to auto start tuning in ten's parts SWR 13 (SWR1.3)
7) Auto mode 1 or 0 to off
8) Calibration coefficient for 1W power, 4
9) calibration coefficient for 10W power, 11
10) Peak detector time in tens, 60 (600ms)

After changing the values you will need to change also the last bite in each modified string - checksumm.

Hi David,

tnx for providing the 1.6 update.

I think it's working as expected. The Power readings are more on the output power of my IC-705 now. 1.5 hat 8.9 Watts and 1.6 shows 9.9/10 Watts on FT8.

Tuning is a little slower than 1.5 but more accurate and giving better match on some bands on my Up-and-Outer for 20m. I could use 15m now which wasn't possible before.

I am unsure what you mean by "After changing the values you will need to change also the last bite in each modified string - checksum". What exactly do I have to do?

Thanks

Hi, All
Version 1.6.3 here, it is Release Candidate

Firmware runs great! David :-)

Auto tune disabled, works like a charm now :-)

Can't wait for the final release.

Thanks

Thanks for the test.?

Firmware 1.6 has been released on GitHub.

https://github.com/Dfinitski/ATU-10-10W-QRP-antenna-tuner/blob/main/README.md

I'm considering adding an ATU-10 to my FT-818 for POTA etc. and those I'm seeing on the various sites are 1.5 firmware versions not 1.6 versions. I've Googled "how to update firmware ATU-10 but haven't come across any info. Can someone point me in the right direction? Any suggestions for which avenue from whcih to purchase one? eBay, Aliexpress, Bangood, etc?

Thank you!

The firmware update was very easy and the 1.6 firmware performs better in matching than the 1.5.
I have updated 3 ATU-10s to use with TX-500 and IC-705.
