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).

It seems Java is not installed or disabled on your computer. You need to install and/or enable it for this website to work properly.
Since Java version 7u51, Java needs to be enabled separately for each website; see http://websdr.org/java.html for instructions.
Your browser does not seem to support HTML5 WebAudio; please try a recent version of Firefox, Chrome, Opera or Safari; or switch to Java.
