>b>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 Do not use VPN or TOR connections, such IP's will be detected and banned from the website. Anonymous IP's are not allowed.

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/
Compare against Firefox Browser as Firefox is known to work perfectly with this websdr.

NOTE 5 All receivers are SDRplay RSP1A and RSP2 ==> Bring me to SDRplay info RSP1A page <==
If you need information on how to install the RSP1A at your own websdr.org-sdr, just mail us, the email-address is listed at the top of this page.

NOTE 6 DSP Noise reduction only works on fast computers, it gives audio stutter-if your CPU is too slow. This is because audio processing is done at the client side.

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:
