As if listening to 75 meter AM from the US West Coast on the train going to work in Melbourne, Australia wasn’t entertaining enough, I googled to discover other WebSDR receivers, thinking an ear in central Europe or the UK might make for an interesting contrast. Websdr.org lists some of the world’s active online Software Defined Receivers. One that looked promising was a station on the wonderfully named Hack Green in Cheshire UK. Hack Green turns out to be a regional Cold War nuclear bunker, established in the 1950s and declassified in 1993. Now the site hosts a popular online SDR.
