5.Why can't some stations be searched?

The distance between the radio and the station is too far, which can lead to a reduction in the quality of the received signal or even cause poor signal reception.

Another possibility is the presence of signal interference in the surrounding environment, which may prevent the radio from receiving signals properly.

Note: Since RR11 is using a wheel tuning mode, tuning and feel have a lot to do with. Carefully and slowly tuning will bring more surprises!
