MultiMode is an application which allows your Mac to decode several different modes of non-voice communication often heard on shortwave. It allows you to decode and display morse code, RTTY, fax, and many other modes on your Mac, without any extra hardware! MultiMode features sophisticated digital filters, for pulling weak signals out of the noise. Lite version only includes RTTY, CW, and FAX modes.
Version 5.9.2: Fixed some bugs in CW mode that affected the accuracy of the speed.
