Attention points
1. The machine adopts SDR architecture. If there is a strong broadcasting station near you, the phenomenon of mirror radio may appear.
2. The input impedance of the antenna interface is 50u03a9. For the LW/MW radio, it is recommended to connect a dedicated active antenna for better listening effect.
3. Please pay attention to the volume setting of the earphone (EAR) before using the earphone to listen to avoid discomfort caused by excessive volume.

Il ricevitore è arrivato in anticipo. Funziona come descritto. Chiaramente le antenne vanno proporzionate in base alla frequenza di lavoro!! Piccolo e leggero, lo trasporti ovunque. Anche l'autonomia è buona!! Lo consiglio... IU1ICP 📡
