3 The Wonderful World ofSoundcardSoftware Copyright West Mountain Radio 2001

4 Why Soundcard Modes? An alternative to CW Ability to get through QRM –Many modes use forward error correction –Code Design –Better signal strength at receive end Ability to transmit large volumes of data accurately, consistently –This varies by mode

5 Why Use the Soundcard? A common component to most computers No need for an expensive TNC or SSTV controller Interface between computer and radio is simple The computer is much more powerful than any stand alone TNC

6 Soundcard Modes Keyboard to Keyboard –RTTY –Stream –MT63 –Hellschrieber –PSK31 –Packet –Amtor –APRS

19 What do I Need?? Transceiver Computer and Software Interface

20 What Rig? Must have these qualities –capable of SSB and/or FM –stable oscillator Most modern rigs will work Some specifically designed for digital –Warbler from NJ-QRP –PSK20 from Small Wonder Labs

21 PSK-80 “Warbler” from NJ-QRP Design by NN1G

22 PSK-20 from Small Wonder Labs Design by NN1G

23 What Computer/OS? Software Dependent –Most programs need a 100-133mhz Pentium or better –Some will run on a FAST (66mhz+) 486DX –Most require a 16bit soundcard Standard for Pentium –Most require Windows 95 minimum A few will run on Windows 3.1 Fewer still are DOS programs

24 What Software? Single Mode –winPSKse –DigiPan –W1QSL PSK –MMTTY –Chromapics Mutlimode –HamScope –RadioCom –JVcomm32 –TrueTTY Too many to mention here. Check out all the software listed on the West Mountain Radio Links page
