Frequency shift ——Deriva frequenza in rx

[It9byl]

hi, i have a problem with my 17 01. until a few days ago let's say it worked. the hotspot works perfectly. when i receive a dmr signal the perfect audio is heard only for a few seconds and then everything starts to unpack and i noticed that the reception frequency has moved by almost 200 khertz. defective radio? thanks to whoever will answer me.
