Black Cat Systems Updates Shortwave Decoding Progam
Black Cat Systems has released an update to MultiMode their code decoder for Ham Radio and shortwave radio operators. The new version brings support for a transmission form called PSK31. According to Black Cat Systems:

This version adds support for PSK31, which is rapidly becoming a popular mode of operation for ham radio operators. MultiMode is the only known Macintosh software that supports PSK31.

The current release version of MultiMode is 2.0.0, released on April 25, 1999. This version supports 44 kHz audio recording, and should work on iMac and newer G3 systems which can only sample at this rate. I'd appreciate any reports from such users, either positive or negative.

MultiMode is a shareware application which allows your Macintosh to decode several different modes of non-voice communication often heard on shortwave radio. It is the only program of its kind for the Macintosh, and rivals commercial packages for the PC platform costing hundreds of dollars.

MultiMode allows you to decode and display morse code, RTTY, FAX, SSTV, ACARS, 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.

In the past, dedicated hardware, often costing hundreds or thousands of dollars, was necessary to demodulate and decode this transmissions. Today, you can use the processing power of your Macintosh to decode and display these modes, without any hardware.

MultiMode supports the following modes:

Morse Code (CW)
RTTY (Baudot)
ASCII
SITOR-A
SITOR-B / FEC / NAVTEX
SSTV (Slow Scan TV)
WEATHER / SATELLITE FAX
ACARS (Aircraft Communications)
PSK31
DTMF, CCIR, EIA Tone Modes
Hellschreiber
Audio Spectrum Display to aid in properly tuning in stations

Black Cat Systems offers licensing worth one full year of updates. So if your license was purchased less than a year ago, this update should be free. The full version is priced at US$45. MultiMode is shareware.

MultiMode 2.0 can be downloaded from the company's web site.
