WinAFSK is a Microsoft Windows application (XP/7/8/8.1/10 [Vista has some issues]) which allows you to decode AFSK1200, AFSK2400, HAPN4800 and FSK9600 packet data in real time from any audio device on your machine such as a radio or sdr device. If you dont have radio equipment, you can use the VirtualAudioCable application or something similar to decode signals off of http://websdr.org
