PLEASE READ: If user count is over 50, do not listen to more than one station at a time out of courtesy to other users (or risk your ip being blocked). This receiver consists of multiple RTL-SDR Ver.3 dongles fed from an HF LNA attached to a G5RV antenna located in Milford, Pennsylvania - Northeastern USA. It is operated by Michael - K3FEF and his XYL, Tanya - W3TKP. Join the K3FEF WebSDR Project Page on Facebook for chat, news, and info related to this WebSDR.
