Station Equipment

All antennas are installed about 10-11m above the ground between the buildings.

  • Every day between 5:00 - 5:20 CET the internet connection is restarted.
  • Unless your browser supports HTML5 audio, you will need both Java and JavaScript enabled for thispage 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) 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).
  • 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.
