    One of my Facebook memories today was this photo of my 4 element yagi made
    from a metal coat hanger. It was used out portable in a contest.
    The mast was a PVC pipe trapped in the car door.

    The latest forecast I have seen is for the peak of solar cycle 25 to occur
    in November next year with a peak around 143, which is better than expected. See http://www.solen.info/solar/.
