ham radio hf propagation map – current hf propagation

QSO/SWL real time maps and lists Send formated DX spots indicating clearly both locators and the type or propagation! The rest of information is useless and it doesn’t interest anybody Make sure your locator is OK in the callbook; Do not chat in the DX-Cluster It’s for spotting DX stations not for chatting! Use DXMAPS chats or ON4KST’s chat instead, Query the DXMAPS database Frequently

 · Propagation along the grey line is very efficient, One major reason for this is that the D layer, which absorbs HF signals, disappears rapidly on the sunset side of the grey line, and it has not yet built upon the sunrise side, Ham radio operators and shortwave listeners can optimize long distance communications to various areas of the world by monitoring this band as it moves around the globe
