Cable between solar cell and the OP is very short, about 15cm.
The cable between the solar / UV interface and the TX unit is about 2.5m for the moment.
I just put a "torus" on the cable to see if it helps to reduce noise. If not i will reduce the cable to 1.8m but i think this is the shorter i can have for the final settlement.
I also order a AD822 OP to see if it makes difference.
I will share my investigations.
