Hi Stefan,

VK dominates WSPR in numbers but not in records -  yet!  :-)

I have been busy with university homework but that's finishing now, so
I will get busy with radio again. My latest experiment is a very
simple WSPR-2 Arduino/DDS/Class-E transmitter. The web page below is
work in progress:

http://people.physics.anu.edu.au/~dxt103/472/wspr_tx/

I have also been doing some tests with a very restricted antenna just
to prove the point that a super large antenna is not the only way to
enjoy the new low bands. Last weekend I did a quick test with the WSPR
beacon from my block of land outside Canberra, using the earth dipole
antenna. I was able to cover 180 km with only 5 W and I know what to
do to improve this. Can't beat a ground antenna when it comes to
convenience!

73, Dimitris Vk1SV
