    Could someone please point me in the general direction for an explanation of the data on this:

    I can understand the HF Conditions being Poor, Fair or Good. My biggest stumbling block on this is for 6 meter and 4 meter where it says 50 MHz ES and 70 MHz ES. What does the ES mean?
    Thank you
    Aaron

    Its called "Sporadic" for a reason! The propagation path can be very pinpoint and last only for minutes or for days. In recent days on 6m I've seen it skipping from me to Belgium with maybe a few northern French thrown in and nothing else. Another day it was all Austria with an occasional German. Then all Portugal with maybe a Spaniard. You get the idea.
    It makes operating interesting! I think that particular report is simply indicating the potential for E-skip to occur. Kind of like "20 percent chance of widely scattered showers" in weather parlance.

    I thought that particular report indicates actual e's propogation
    for the 20% chance of showers it shows high MUF as the report.
    Could be wrong IDK

    Sometimes to catch the DX you need to put out a few CQs.

    It's like catching fish. Use two lines and the fish can still ignore you.:p
