This evening, quite unexpectedly, I got a string of reports on 500kHz= WSPR from OH1LSQ in KP03sd at an astounding distance of 1733km. To me these= are amazing reports pushing my best DX on the band with just a few milliw= atts ERP to new levels.  What surprises me is how well a very simple= vertical wire loop works as a TX antenna: the wire is just 1mm diameter, with an area of around 70m square with par= t of the loop laying on the ground buried in wet grass.

Even more than before, I now believe almost anything is possible.

Now I just need to repeat this on 137.5kHz....
