Why do coronal mass ejections benefit radio stations?

Coronal mass ejections (CMEs) can benefit radio stations by enhancing the ionosphere's density, which improves radio wave propagation. This increased ionization can lead to better signal transmission over long distances, allowing for clearer reception and expanded broadcasting range. Additionally, some radio stations, particularly those using high-frequency (HF) bands, may experience temporary boosts in signal strength due to these solar events. However, it's important to note that CMEs can also cause disruptions and interference, so the effects can be mixed.
