App Store Description
High frequency (VHF, also known as meter wave) in China is in the frequency range of 48.5mhz-223mhz
UHF (decimeter wave) frequency range in China is 470mhz-806mhz
Short band (HF section) radio signals below 30MHz are transmitted by ionosphere reflection over a long distance, which can travel from hundreds of kilometers to tens of thousands of kilometers. Due to the particularity of the ionosphere itself, the reflection of radio signals above 40MHz in the ionosphere is very weak under normal circumstances, and most of the signals will penetrate the ionosphere into space
