A WebSDR is a Software-Defined Radio receiver connected to the internet, allowing many listeners to listen and tune it simultaneously.

** Sometimes disabled To improve the communication antenna system For better listening. Thank you. **

SDR technology makes it possible that all listeners tune independently, and thus listen to different signals; this is in contrast to the many classical receivers that are already available via the internet.

This is a WebSDR receiver, located in Amphure Mueang Nakhonratchasima OK14BX Thailand. It is operated by HS3LIQ/Wiwat, e-mail nott0209 at gmail.com
