Digital Communications via Sound Card Overview Introduction
This page is designed to provide you with some recommended software for use in digital communications in the North Central Division. Keep in mind that the flow of new and better modes and software are continuing to develop. Some of the software listed here is being improved as this is being written so attempts at announcing updates will be made. The compter sound card and lately sound cards built into interfaces and into radios have eliminated the need for relatively expensive TNCs. Keep in mind that although much of what is listed is in use in MARS operations, USAF MARS in no way endorses or supports any of the programs or interfaces listed here. The list has been compiled to help you in locating programs that are known to work with sound card interfaces. As you should expect, some programs will work better than others and some will not work at all with certain computer / sound card configurations. I recommend that you download and evaluate several programs to determine which ones work best for you. If you find any of the referenced links non-operational or would like to add new links please feel free to contact me. Shareware, Freeware and Commercial Sound Card Programs

Fldigi s a computer program intended for Amateur Radio Digital Modes operation using a PC (Personal Computer). Fldigi operates (as does most similar software) in conjunction with a conventional HF SSB radio transceiver, and uses the PC sound card as the main means of input from the radio, and output to the radio. These are audio-frequency signals. The software also controls the radio by means of another connection, typically a serial port. Fldigi is multi-mode, which means that it is able to operate many popular digital modes without switching programs, so you only have one program to learn. Fldigi includes all the popular modes, such as DominoEX, MFSK16, PSK31,OLIVIA ,MT63,CONTESSTIA, RTTY,QPSK,THOR, THROB,WEFAX AND NBEMS Modes, NBEMS refers to Narrow Band Emergency Messaging System an organized group dedicated to digital emergency communications.

MixW is and excellent multimode program that operates in similar fashion to all of the other programs and is provided with a 15 day trial limit and then requires a $50 registration fee to keep it operating in full feature. MixW also includes all of the popular modes used today. CW, RTTY,PACKET, PACTOR & AMTOR(Recv.only), PSK,QPSK,FSK31, MFSK,THROB,HELSCHREIBER,MT63,FAX,SSTV,OLIVIA AND CONTESTIA.

MultiPSK is a very complete program which includes all of the modes in use today plus a number of other which are not so popular. Instead of using menus off of the operating page to list the various programs they are all presented in the graphical interface which make for a very cluttered screen . Some operators avoid this program for this reason but it is a powerful program.
