| Sporadic E Propagation - VK3FS
Sporadic E propagation is a result of highly ionized patches or “clouds” that occasionally form in the E region of the ionosphere at altitudes between approximately 80 and 150 kilometres.
Communication distances of 800–2000 km can occur using a single Es cloud. This variability in distance depends on a number of factors, including cloud height and density. MUF also varies widely, but most commonly falls in the 25 – 150 MHz range which includes the amateur radio 2 meter, 6 meter, and even the 10-meter bands. Strong events have allowed propagation at frequencies as high as 250 MHz.
