Today I downloaded WSPR software and install the program to see how it will work. Weak Signal Propagation Reporter Network [link]. I transmitted 1 watt and later 500 milliwatt on 30 meter. Automatically the program send and received the data, and all I have to do is watch how things are going. Click on the photo to enlarge the picture. Here you see my reports. Or look here. SV8ARJ received me with 0,5 and 1 watt distance 2019 km. OH2BMH 1513 km. And TK1DP from Corsica, distance: 1223 km.
