He is now sporadically on VHF enabling DX connections. Signals reach Turkey from Poland. It remains to be seen whether it will be moved to include the OK/OM of radio amateurs on VKV. You are watching DX cluster or KST chat. GL!
Es propagation on VHF
Es propagation on VHF (E‑sporadic propagation) is a type of radio wave propagation in the VHF (VHF, 30–300 MHz) bands that allows surprisingly long connections, often hundreds to thousands of kilometers, in bands where only direct propagation of a few tens of kilometers is normally expected. This phenomenon is caused by the formation of thin, temporary layers of the ionosphere in the E‑layer (100–120 km above the surface), which can reflect radio waves back to Earth.
It is also called sporadic Es, because the layers appear irregularly and are short-lived, often only a few minutes to hours. It occurs most often during spring and summer, especially in middle latitudes. Radio amateurs use Es propagation on shortwave and VHF links, especially on 50 MHz, 70 MHz and 144 MHz, for DX links, contests and experimental operation, because it makes it possible to receive signals that would otherwise be impossible to receive.
