IQRec @ Home Home     Access count

IQRec is a program to record the signal (mono, stereo) from a sound card to a wav file, and display the frequence spectrum. It is possible to break the recording in separate files of 1 minute to 2 hours, and to start and stop the recording on some specified date / time. The wav file can be used with other SDR receivers (like WinRad from Alberto I2PHD or Rocky from Alex Shovkoplyas VE3NEA) to listen to the signal on a later time.
