MultiMode Version 0.4.1§ 9 August, 1997
Introduction:
MultiMode allows you to decode several digital modes on your Mac.
Please note that starting with this version, a PowerMac (PowerPC processor) is required.
The 680x0 just didn't have the necessary horsepower. I've done all testing on a
PowerComputing PowerCenter Pro 180 (604e). I'm anxious to hear how MultiMode
performs on other machines.
Why did I write it? I've always been disgusted 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 decoder for the Mac.
This version decodes the following modes:
¥ Morse Code (CW)
¥ RTTY (Baudot and ASCII)
¥ FAX (120 lines/minute)
¥ SITOR-A
¥ ACARS
¥ WWVB Time Code
Eventually I'd like to add full support for RTTY, FAX, SSTV, etc. That's where you come in
(more details about that later on). All you need to do is connect your radio's audio output
to your Mac's sound input, and start the program.
The user interface has undergone massive changes since the previous version (I hope for
the better!). Menu selections are gone now, a small window just under the menu bar
contains small buttons to select the various modes and settings. This window (called the
Signal Window) also displays the received signal in CW and RTTY modes, to help with
tuning your radio.
For CW, it defaults to about 13 wpm. There is an auto-detect feature to determine the
proper code speed settings. Two windows are displayed. One shows the audio input, so
you can adjust tuning and volume levels. The other is the display of the deocded text.
There are no provisions to save or print the text, although this will come in time.
Basic Operation:
The large buttons on the left side of the Signal Window select the mode of operation -
CW, RTTY, or FAX, SITOR, ASCII, or one of the signal tuning aids.
Thanks again for giving MultiMode a try. 73's and good DXing!
