G3XBM achieves 1733km on 500kHz

On Thursday, October 21, Roger Lapthorn, G3XBM, achieved a distance of 1733 km on 500 kHz using WSPR.

He writes:

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..

Roger G3XBM is giving a talk to the Chelmsford Amateur Radio Society (CARS) on Tuesday, November 2, visitors from other clubs are most welcome, see
