WARNING, Since September 2018, the Chrome browser occasionally starts to play white noise on Vesuvio WebSDR sites. As a workaround, muting and unmuting usually restores normal audio. Chromium engineers are looking into the problem. Alternatively, use a different browser, like Firefox. In December 2018, Chrome v71 seems to have fixed this issue!
