There can be multiple reasons why your digital radio reception is poor. One possible reason could be the distance between your location and the nearest broadcasting tower. If you are located far away from the tower or there are physical obstacles like buildings or hills blocking the signal, it can weaken the reception. Another factor that affects digital radio reception is electromagnetic interference caused by electronic devices such as mobile phones, Wi-Fi routers, or even faulty electrical wiring within your home. Additionally, if your digital radio antenna is damaged or not properly positioned for optimal signal reception, it could contribute to poor reception.
