PCBA size: 58x49x10mm Kind reminder: The radio is used to receive signals emitted by broadcasting stations, and the reception effect varies depending on the listening environment. For areas or buildings near large signal stations, due to signal interference or shielding, when listening to a certain radio wave, there may be mixed or all noise, which cannot be eliminated! When listening, it is recommended to stay as far away from household appliances as possible and adjust the antenna direction as close to and as possible! It's DIY kits, needs to finish by yourself.
