RE: Ionospheric Layers: Description, Constituents, anomalies and Effect on Radio Wave Propagation
Nice one. No wonder some radio station signal are clearly seen in the morning and diminishes at night

Yeah, the sun generates signals that look like radio signals therefore the radio can't distinguish between the natural signals and radio signals.
Yes A.M signals are very susceptible to interference especially during the day time. but at night they can travel miles by the phenomenon called skywave propagation.
Yeah, thanks for the additional information.
Yes right...In addition the disappearance of the A.M signal is also due to the fact that the D layer attenuates low frequency signals which is a factor of the ionization present in this layer. When this layer is no longer there at night, A.M frequency can take advantage of their relatively long wavelength and travel farther than F.M
