Black Cat Systems has updated MultiMode (http://www.blackcatsystems.com/software/multimodeOSX.html), a Mac OS X application that lets your Mac decode several different modes of non-voice communication often heard on shortwave, to version 6.2.3. This version corrects some bugs related to text macros.
MultiMode is an US$89 application that lets your Mac decode and transmit several different modes of non-voice communication often heard on shortwave and ham radio. It allows you to decode and display Morse Code, RTTY, FAX, SSTV, ACARS, PSK31 and many other modes on your Mac, without any extra hardware. MultiMode now also allows you to transmit in most of the modes of operation.
MultiMode Lite is also available, which offers reception of CW, RTTY, and FAX modes only. MultiMode Lite is ideal for sailors who need to be able to view weather charts and reports, but don’t need the extra modes, or transmit capability.
