There is still/again an intermittent problem with the antenna or more likely its cable,
causing a high noise level on 80m. We'll try to fix it, but we're no magicians...
Antennas are installed about 6m off the ground and there are many buildings nearby.

If you don't hear anything, probably Java is disabled or its version is too old (i.e., pre-1.4.2) or your browser does not support HTML5.
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). The Web Audio autoplay policy will be re-enabled in Chrome 71 (December 2018).
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.
Remember: If you don't do something (e.g. retune, adjust bandwidth, volume) this WebSDR will time out after 120 minutes. If it does time out, refresh 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.
