Ionospheric lines

WebDefinition: A type of radio wave communication in which the electromagnetic wave propagates due to the reflection mechanism of the ionospheric layer of the atmosphere is known as sky wave propagation. Due to propagation through the ionosphere, it is also known as ionospheric wave propagation. WebPay special attention to the line dividing day and night (the terminator, or as hams call it, the "greyline"). Unique propagation opportunities are often available when one station, or …
