You can troubleshoot and optimize the reception by following these steps: 1. Adjust the Receiving Environment and Location Stay Away from Interference Sources: Skyscrapers and reinforced concrete structures in urban areas can block signals. Meanwhile, electronic devices such as TVs, computers, routers, microwaves, fluorescent lights, and thyristor dimmer lamps generate strong electromagnetic interference. Please keep the radio away from these devices as much as possible. Move to an Open Area: Signals attenuate significantly indoors or in basements. It is recommended to move the radio near a window or take it outdoors to an open, unobstructed area for testing. 2. Optimize the Antenna Status Fully Extend the Antenna: Make sure the telescopic antenna is fully extended to its proper length. A broken or loose antenna will drastically reduce the signal reception range. Adjust the Angle: For the SW band, the telescopic antenna is the primary receiving component. Try rotating the direction of the radio or adjusting the tilt angle of the antenna to find the spot with the strongest signal. 3. Choose the Best Listening Time Listen at Night: Shortwave (SW) signals are mainly transmitted through ionospheric reflection. At night, the ionosphere becomes thinner, which reduces its absorption of shortwave signals and enhances its reflection capability. Therefore, shortwave signals are much easier to receive clearly at night (especially after sunset) than during the day. 4. Check Device Settings and Status Check Battery Level: Ensure the radio's battery is fully charged. Low battery power may cause the internal circuits to malfunction, resulting in decreased signal reception sensitivity.
