At the November meeting of the club, Bryan M0IHY talked about SDR receivers in general, and the SDRplay receiver in particular. (See the recording of the club meeting HERE)
His demonstration did not go to plan, most likely due to an antenna problem. Bryan repeated his demonstration from home, and recorded the result.
Here is his complete home recording which covers the principles of SDR as well as the demonstration of using the SDRplay receiver with the accompanying software SDRuno.
