NOTE 1 You need both Java and JavaScript enabled for this page to work properly.
If you don't hear anything, probably Java is disabled or the version is too old (i.e. pre-1.4.2).
NOTE 2 Antenna is normally Inverted-L (54m longwire) but can also be a MiniWhip or G5RV (2x17m), depends on the bands I'm using myself.

NOTE 3 Typical bands below 10MHz use LSB and bands above 10MHz USB, however, 60M uses USB as well as most professional users like coastguard and aircontrol.

NOTE 4 No sound with Google Chrome Browser? Try this: chrome://flags/#enable-autoplay-ignore-web-audio -> set enabled.
From version Chrome v76.0.3809.100 try this: chrome://settings/content/sound -> allow/add url: http://heppen.be:8091/

NOTE 5 For blind people, the list of waterfall tags can be downloaded here: ==> Click me <==
However, the list is longer then the bands we support, keep that in mind.

Please support this project with a small donation so we can buy even better receivers in the near future as better and wider receivers are real expensive:
