6: Q: Why the radio sound out of the speaker, when using ear buds?
A: Because the ear buds have MIC function, in fact, this radio can't work with the ear buds which
have MIC function.
So, you can try an ear bud without MIC function, if still can't solve, please email me freely
7: Q: Why the SW reception is not good?
A: Shortwave is a delicate medium. Little things like time of day, the sunspot cycle, weather and
atmospheric issues can play the devil with reception. But once the sun goes down, the shortwave
bands come alive with music, news, propaganda and even some pirate radio stations. So, the signal
strength will be weak indoors than outdoors.
So, the best way to listen to shortwave should be: extend antenna, in night, and outdoor.
