Setting Si5351 in setup

[Gunka]

Hello, I use software 4.2 Air beta and have added Si5351 to the oscillator on the ATS25 and implemented the band extension. When the receiver starts, the Si5351 is recognized and both oscillators of the Si5351 work correctly, although the Si5351 is not activated in the setup.
My question now would be, what does activating or deactivating the Si5351 do in the setup? I haven't been able to find any information about this yet. I can hardly notice any difference with different settings. Thank you for helping!

Gunka, This is an experimental setting that ended with a negative result. The subsequent updates are deleted. So just turn off this option.
