Radio closing effect

The number of radio receivers in Desheng R-909 depends on the local signal status. If the signal is good, there will be more receivers, and if the signal is poor, there will be less receivers.

The machine has a 360-degree rotating antenna with strong ability to receive signals. When listening to short wave or FM radio stations, pull out the antenna and change the length or angle to achieve good results. When receiving international radio stations and remote weak signal stations, the Switch "local/remote selection sensitive switch" should be set to DX (remote) position to improve sensitivity and reception capability.
