I haven't thought that this is possible, almost not even on 160m. We want to see more of these tests, Roger :-)

Good luck and fun!

BTW, what is your next step? Any new ideas?

I wish OH1LSQ would be RX QRV on 8970 Hz...

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 milliwatts 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 part 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....
