![FMDX a playful FM-radio band MARINE TROPO by the sea, coast of Finland possibly AIRCRAFT SCATTER too
Perfect contitons for a playful FM-radio band MARINE TROPO [M/Tr] on South-West coast of Finland on a calm and sunny spring afternoon, 27th March 2021. Many distant FM-stations across the Baltic Sea were logged here on that same day... Note how a FM-signal received during similar conditions just few days earlier fluctuates while finding its way throug forming temperature inversions over the sea. Location and angle of view shown here: http://bbs.fmdx.tk/index.php?topic=519.msg2179#msg2179
(www.dxinfocentre.com): Marine Tropo occurs when warm dry air overrides a cooler body of water. Marine inversions often extend the entire breadth of lakes and can extend for thousands of miles over the ocean. It also spreads into coastal areas by way of sea or lake breezes. Marine tropo can become enhanced or combined with other types such as High-Pressure Tropo. It normally peaks during the afternoon when the inversion is the strongest. Outside of the equatorial zone, spring and early summer is the best season.(www.dxinfocentre.com)
Possibly some airplane scatter was also involved : https://i.ibb.co/FwpN7ht/2021-03-25-14-28-48-UTC-Flightradar-vs-signal-path.png and https://www.youtube.com/watch?v=eapdP9rKGCA
