I am currently building a sloping 1/4 wave ground plane. I have a Cobra 148 modified to about 28 MHZ( operating range 10 to 11 meters). What frequency should I use per resonance, i.e. for what frequency should I cut the length of the radiator so as to maintain a acceptable SWR across the board. Thx, Joe

    Incoming Region Produces X3 Solar Flare
    May 15, 2024 @ 14:55 UTC
    Another major solar flare, but this time from an active region just beginning to turn into view off the east limb. It is possible that the group responsible is old AR 3654 from the previous rotation. The latest flare, an X2.99 event just peaked at 14:38 UTC (May 15). Stay tuned
