This is a WebSDR receiver, located in Silec, Poland, QTH KO04SD. Photos available here -- yes, highly experimental design. It is operated by Argon. More information about the WebSDR project can be found on http://www.websdr.org. Note: for listening to UVB-76 / UZB-76 / МДЖБ / ЖУОЗ / Buzzer, please try the stream: http://streams.printf.cc:8000/buzzer.ogg. It could help saving some bandwidth.
