This amateur radio website explains how to use the free AGWPE utility program to send and receive packet data using the sound card of your PC. The author of AGWPE is a talented ham from Greece, George Rossopoulos SV2AGW. Note that AGWPE is a Windows-only program.

Since AGWPE's breakthrough, other sound card packet programs for Windows have been developed. They include:

(Thomas Sailer, HB9JNX/AE4WA developed a soundcard packet capability for Flexnet  before AGWPE.)

This website, which is hosted on SV2AGW's web site, focuses on support for the sound card packet features of AGWPE. It does not attempt to provide support for other sound card packet programs, however, it has has general information which is applicable to all sound card packet operations:

  •  compatible packet programs that can link to AGWPE
  • some ideas for interfaces to connect sound cards to ham radios
  •  resolving problems with packet operations
  •  ways that packet is used today

Note that this website was started in 2000. In 2015 it was updated to reflect changes for Vista and more recent versions of Windows, but little was done to update pages dealing with older versions of Windows and older hardware.

If you encounter problems with AGWPE, you can e-mail me NM5RMRemember I am not the software author and I don't pretend to be the complete AGWPE sound card expert, but I will try to answer your questions.  For the best troubleshooting help, I suggest you subscribe to a special AGWPE Yahoo Group email list to ask for help from the AGWPE user community, which includes the AGWPE author, George SV2AGW.
