Despite all sorts of local electrical noise in the room from fluorescent lights and computers I'm hearing Ross, VK1UN (in Victoria) pretty well.
Note that previously VK4BV had me at +10db SNR and now I'm -9 so that's much worse but due to the huge dynamic range WSPR can handle it's great to get a reading at all.
Later it's getting better:
WSPR provides a good platform for evaluating indoor antenna options.
