Note: you need both Java and JavaScript enabled for this page to work properly. If you don't hear anything, probably Java is disabled or its version is too old (i.e., pre-1.4.2).

Since April 2018, the Chrome browser is reluctant to play audio on WebSDR sites.
If you use Chrome and have no audio on WebSDR sites, a workaround is to switch off Chrome's new autoplay policy, by typing chrome://flags/#autoplay-policy in the navigation bar and
changing this setting from Default to No user gesture is required (and restarting the browser).
