The 500 KC Amateur Radio Experimental Group
www.500kc.com
Website of the 500 KC Amateur Radio Experimental Group, focusing on experimental communication on the 500 kHz band.
A niche corner of the radio hobby, this site preserves and shares experiments conducted on the largely unused 500 kHz band. It suits amateur radio operators with a taste for low-frequency experimentation, and its independent character fits OddSurf's small-web browsing mode.
