Woman looking through a mangifying glas

At the second HamRadioWeb convention in Bolognia, Italy Claudio, I4LEC has given a great presentation about the current status of SDR. In his presentation he starts with SDR principals then analyzes then the strength and weaknesses of available Software Defined Radios (mainly FlexRadio Products) and finishes with a comparison against TS-590 and Elecraft K3. The presentation is entertaining and informative at the same time. Definitely worth having a look at!
