Heard in VK on 40m QRP again

At 1834z, 30 mins earlier than last night, VK8CH reported my 5W WSPR signal at SNR -27dB, which is 1dB lower than last night. A few hours later, VK8CH copied my 2W (33dBm) 40m WSPR signal at SNR of -24, -27 and -28dB over a period of some 20 minutes. PY2GN has heard me twice tonight already on 30m WSPR, again using 5W. W1XP was copying my 1W 30m WSPR signal at a SNR of-17dB.

All this on 15m of end-fed wire strung from the gutter to the washing line post at the bottom of the garden!
