SOFTWARE FOR THE DIGITAL MODES If you are new to using digital modes and this is your first time setting up an interface (or if you just want to refresh your memory), Donner's Digital Interfaces has designed an e-book that will help you setup your interface and get started in the digital modes. To download this e-book, click on the link below. GETTING INTO DIGITAL COMMUNICATIONS (download) Or if you would like to view the tutorial online just click on the link below: GETTING INTO DIGITAL COMMUNICATIONS (online tutorial) To use any interface box with your computer and radio, you will need the appropriate software for your computer.  Donner's Digital Interfaces does not supply the software because there are many varieties of good software already on the market.  Best of all, most of it is FREE! Some software is designed for a specific digital mode (i.e. SSTV, PSK31, RTTY, etc.);  others will do a variety of modes with one software.  You will need to decide which is best for your needs, your computer, etc.  Although you don't need the latest, fastest, biggest computer on the market, please checkout what the particular programs need in system requirements.  If you have a computer that runs at 100 Mhz or faster, has a Sound Blaster Pro or better soundcard, you have what it takes to run most of these software programs.
