Solar Flux [SFU]


    Solar Flux is measured in solar flux units (SFU) and is the amount of radio noise or flux that is emitted at a frequency of 2800 MHz. The solar flux is closely related to the amount of ionization and hence the electron concentration in the F2 region. As a result, it gives a very good indication of conditions for long-distance communication.
    The higher the solar flux, the better for amateur radio.

    The DXZone merges amateur radio and Internet, since early internet days. Established in 1996 as a radio-related-mailinglist, has registered its domain name in 1998. Main goal is to review and promote ham-radio web sites, classifying them in categories. The DXZone is managed by ham radio operators with ham radio operators in mind.
