MultiMode Version 3.7.1   September 12, 2000

Introduction

MultiMode allows you to decode (and transmit!) several digital modes on your Mac. Best of all, MultiMode is shareware!  Please read the chapter on Registering to discover how you can register your copy, and help support software for the Macintosh.

This documentation describes both MultiMode and MultiMode lite. The lite version is identical, except that it is receive only, and only supports CW, RTTY, ASCII, SITOR A/B, FAX, and FFT modes. 

If you're an existing MultiMode user, please be sure to check the Release History at the end of this documentation, to see what changes have been made since your last version.

Information on transmitting is scattered throughout this document, in the relevant mode sections. 

Please note that effective with version 3.0.0, MultiMode only runs on PPC Macintosh systems. 68K Macs don't have the processing power necessary.

I've done all testing on a PowerComputing PowerCenter Pro with a G3 CPU card, and an iMac DV. I'm anxious to hear how MultiMode performs on other machines.

Why did I write it? I've always been frustrated with the lack of decent ham/radio software for the Mac. Why should the wintel boys have all the fun? I've written several other Mac radio related programs in the past (check my web page for details), and have often had requests for a CW/RTTY/FAX/SSTV/etc. decoder for the Mac.

Eventually I'd like to add full support for other modes. That's where you come in (more details about that later on). 

Please read through the chapter on registration, to learn how you can register your copy of MultiMode, and help support ham radio software for the Macintosh.
