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 All receivers are SDRplay RSP1A ==> Bring me to SDRplay info RSP1A page <==
NOTE 6 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.

|15/06/2019 - Motherboard replaced with Q1900M 4x2GHz CPU, had some troubles to get it working, turned out speedstep was messing websdr up.|
|03/11/2019 - Java-sound fixed, hopefully, as I have no way to test it.|
|15/11/2019 - Drivers finally fixed on bad sample quality, especially AM signals suffered. That was a hard nut to crack!|
|15/12/2019 - Got my hands on an i5-4440 with motherboard so I replaced the Q1900M, it allows me to use better driver settings.|
