Just for kicks I tuned up the 43ft vertical on 40M and listened with the WebSDR receiver at University of Twente in the Netherlands. I was right at the noise -105 dBm but I was definitely copy-able. Not bad for 10W to a piece of wire up on a tree. I plugged in my 1/2 wave end fed 40M vertical over several thousand feet of wire and became 559 at -98 dBm. I even saw a -92 dBm but wasn't quick enough on the capture to record that.
