Power calibration doesn't work

I try several time on different power with no success

5w 50w
10w 50w
5w 100w

@DG4SN can You help a little :-)

Hello SP3SWJ,
I have tested the calibration with 5W and 10W.
Does the calibration work in principle?
Are all calibration steps working?
Unfortunately, I don't work on the project any longer and I have forgotten the details. :(
Did you plan to develop the source code further?

Thank for replay.

One things on begin I must "develop" reverse LCD - to fit my hardware ( loaded to my fork)

Some video fr my HAM friends https://youtu.be/AgmzYGtPWvo how tuner works

OK will try with 5 and 10 - but convinced test a lot different pairs

I try go according to recomendations :-)

Finally to have propper working ATU I have two options

• flash again and reset tuner this method
• Calibrate on 0 and 5W with two mimimum sets to have "almost" good power reading

Will made video to show how action perform.

Thanks again for feedback :-)

I normally use FC-40 Yaesu and FT-710 - but for my FT-817 would like use this ATU-100

I saw you have DEPUB serial print - to what pin send data ? - this can be used to external remote "status dispaly" :-)

Hello Jerry,
On the video i have seen that the "Auto" mode was always on.
Have you tried it also when “auto” mode was off?
I used a serial debug print for developing.
Currently it is commend out in defines.h file in line 27.
The port/pin that I used was A6. (defines.h line 63)
It is reachable on the bottom side of the PCB

Will try next with NO AUTO

look how this works

Calibration with AUTO off doesn't solve problem
