SAQrx is a soundcard based USB (Upper SideBand) receiver covering 0-22 kHz. The filter bandwidth is selectable in three steps, 300, 1000 and 2400 Hz.
SAQrx was written primarily for reception of the 2006 Christmas transmission from SAQ but it was made tunable so it can be used for other purposes while waiting for the next SAQ transmission :-)
SAQrx requires a soundcard capable of full duplex at 44100Hz sampling frequency. Most soundcards can do this.
Installation is simple: Download saqrx06.zip (below) and unzip the file in a folder of your choice. There is only one file, SAQRX.EXE, just double click it to start the program. SAQrx has only been tested on Windows XP but may run well on some other Windows versions too.
Removal is even simpler: Just delete the file SAQRX.EXE.
The SAQrx program is believed to be totally harmless, I have never heard of any problem, but YOU ARE USING IT AT YOUR OWN RISK!
