| UNIQUE reports received on 15m baseline earth-electrode antenna on 474.2kHz WSPR |

More 474.2kHz WSPR success
Overnight my transmissions with the 15m baseline earth-electrode antenna continued. A couple of reports from Holland were added to the list of spots bringing the total UNIQUE station reports to eight. The only change has been to resonate the loop with a small series inductor. This increased the loop current by about 20%. Next to try will be to see if the 50 ohm match can be bettered with a small auto-transformer. I suspect not, but we'll see.

Hi Roger
Very good results you seem to be getting some good coverage with your new setup. I would love to get into doing some WSPR experiments. I am thinking of getting the ultimate QRSS kit and trying some QRSS on 470KHz and WSPR on the other bands.

I am buying an Ultimate 3 kit with GPS to use in 10m Tony. May well increase power to 1-2W as success rate better at that power, but have been copied OK in the USA with 100mW only.Ultimate 3 puts out 130mW typically at 10m. 474.2kHZ WSPR is great fun.
