Results of my second MEPT experiment

From 16/9/2010 to 24/9/2010 my 30m MEPT was transmitting on 10140.080 KHz with FSKCW6 and only 160mW of power. This time the results were much better compared to the first experiment.

I received reports from 14 stations (DL4MGM, G4CDY, G6AVK, I2NDT, ON5EX, ON5SL, OZ9QV, PA0TAB, PA1GSJ, VE1VDM, VK2DDI, W1BW, W4HBK, ZL2IK) that are located on 10 DXCC countries (Germany, England, Italy, Belgium, Denmark, Netherlands, Canada, Australia, United States, New Zealand) and 3 continents (Europe, North America, Oceania). My longest DX was ZL2IK from New Zealand (again) but this time through long path! The long path distance between us (from KM17uw to RF74ci) is 22628 km and this rises my personal QRPp record to 141425 Km Per Watt!

The experiment results have been compiled as a KML file that is readable from Google Earth and Google Maps. In this way the reception reports log is more interactive. The color of each placemark defines the type of the station (MEPT or receiver). When the user clicks on a placemark the description of the reception report appears (date, time, location etc) including a small thumbnail of the received signal that is linked with the full size screenshot of the FFT software. The final result of the produced KML file is shown below:

Many thanks to all stations that sent me their reports. More experiments will come with lower power levels and slower code speeds. Stay tuned!
