  • TT8TT worldwide propagation charts

    We have prepared these worldwide propagation charts, based on the following values of the parameters:
    Solar Flux Index = 120 sfu
    Geomagnetic activity: Quiet
    Transmission Power = 500W
    Antennas: 3 el. yagi from 10m to 20m and dipoles from 30m to 160m
    These charts can help you to choose the best frequency to work the DXpedition, depending on the area where you are.

    The color of the cells is given by the sum of two parameters: the probability of opening and the estimated signal strenght. Legend of colors: red = good chance of QSO good, green = average chance of QSO, yellow = low chance of QSO

    Geomagnetic activity: Quiet

    Obviously, if there is a strong geomagnetic storm (for example, at the moment the index kp is 7 !) the MUF fall significantly and therefore the possibility of QSOs on the higher bands for paths involving the mid and high latitudes.

    For example, this is the propagation charts for W6 with Kp = 7

    Compare them with those carried out under conditions of quiet geomagnetic.

      nice work... it would be interesting to know differences from your "reference station" and a 100W + vertical antenna one.
