Ionoscatter ist eine Ausbreitungsart fΓΌr Funkverbindungen auf Ultrakurzwelle.
Dabei werden Funksignale an Turbulenzen in der D-Schicht der IonosphΓ€re gestreut. Aufgrund der HΓΆhe der D-Schicht ergeben sich Verbindungen ΓΌber Distanzen von 1000 bis 2000 Kilometer, was deutlich ΓΌber der normalen Reichweite von UKW-Signalen liegt. Im Gegensatz zu Γberreichweiten bei Sporadic-E- oder Meteorscatter-Verbindungen ist Ionoscatter jeden Tag mΓΆglich, am besten tagsΓΌber auf dem 6-Meter-Band. Γblicherweise weisen die Signale ein rasches Fading auf.
