Not sure if anyone here is at all interested in Ham radio or Shortwave listening but I found this a few days ago and have been intermittently listening in. A couple of more active feeds, Leave a window open minimised for a while if it's silent but the player clock needs to be running (might need click it).
Click the broadcastify logo and you can access emergency services and other channels from many countries - not much in UK though. Australia is another good one to check. ( Queensland - www.broadcastify.com/listen/stid/155 ) With the listing you can see how many are listening which gives an idea where something is going on.
