WSPR beacons ARE a LAZY APPROACH no skills required and vy limited regarding propagation predictions. I had two nice solid QSO'S two nights ago on CW/QRS to Russia and Romania. I did not need WSPR assistance. Any experienced CW operator can check a band and give an opinion about propagation in real time, then proceed to make a QSO.
