Description

What type of issue is this?

permanent - occurring repeatedly

What issue are you facing?

Tuning failure/PLL lock when trying to use after updating to 2026.01.2 with (tested) SDR Console and GQRX. The symptoms are dead spectrum, PLL drift, it stabilizes after changing frequencies several times,

What are the steps to reproduce this?

It is not a temperature stabilization, i have checked the hardware (thermal, crystal, etc.) It happens also with the previous firmware 2026.01.1.
I just tried reverting to 2024.02.1 and so far the problem is not reported also it was tried going back and back to the latest version.

Can you provide any logs? (output, errors, etc.)
