Quadrature signal Recording
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.
Recorded data from this program at the 40m Radio Amateur Band can be found here. It is recorded with a good quality soundcard the M-Audio Delta-44 at 96K samp/sec (the I&Q data files are big, about 675Mb!!).
Sometimes it can be crowdy with all that CW!
