Note: you need JavaScript enabled for this page to work properly. If you don't hear anything, and you use an old browser or Internet Explorer, you need to install and enable Java as well, and allow it to run on this website (this is discouraged because of the security risks, it is better to install a modern browser instead).

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).

Since Java version 7u51, Java needs to be enabled separately for each website; see for instructions.
