Except for local contacts, which are primarily made on Very High and Ultra High Frequencies (VHF and UHF), communicating between any two points on the earth rely primarily on high-frequency (HF) signals propagating through the ionosphere. The earth’s ionosphere acts much like a mirror at heights of about 150 miles. WebRadio Communication and the Ionosphere. The ionosphere is a region in the upper-atmosphere that meets space (exosphere). A mixture of free electrons and ions (known as "plasma") is created when solar radiation ionizes gases 80 to 600 km above the surface of the earth. The high densities of free electrons significantly affect radio communication. on the spot murder mystery dinner show
