Hello,
I am encountering an issue with my SunSDR2 DX. After a while, the audio from the jack labeled "Phones" on the front of the device becomes distorted, making it impossible to listen to. A brief power cycle (on->off->on) resolves the problem temporarily. Notably, the sound via the PC sound card remains consistently good. The distortion occurs even when only listening, i.e. RF issues.
The SunSDR2 DX is running ExpertSDR3 version 03112023, and this problem is not new; it also occurred in the previous ExpertSDR3 version. The firmware version is EED06202100632.
I have attached a short recording of the distorted sound, followed by the power cycle, for reference.
