Link to new WebSDR for 20m band

Since September 2018, the Chrome browser occasionally starts to play white noise on 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 , Chrome Beta or Microsoft Edge.
