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. Note that AGWPE is a Windows-only program.

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

  • some ideas for interfaces to connect sound devices to ham radios
  • resolving problems with packet operations
  • ways to use packet today
  • information about packet programs (clients) that can use AGWPE as a host for sound card packet operations

AGWPE was created by a talented ham from Greece, George Rossopoulos SV2AGW. Since AGWPE's groundbreaking development, other sound card packet programs for Windows have appeared. They include:

  • Packet Engine Pro, a more advanced but "pay for" version of AGWPE, also written by SV2AGW
  • The UZ7HO Soundmodems which works with all programs that work with AGWPE
  • Dire Wolf,  designed especially for APRS functions
  • And several multi-mode sound card programs, including MixW and MultiPSK

Note that Thomas Sailer, HB9JNX/AE4WA developed a sound card packet capability for FlexNet before AGWPE came along, but it would only work with the FlexNet program.

This website began in 2001 soon after the release of Windows XP. In 2015 it was updated to reflect changes for Vista, Windows 7, 8.0 /8.1 and 10, but little was done to update older pages dealing with older versions of Windows or older hardware  -- so you may find vestiges of outdated or inapplicable information.

If you encounter problems with AGWPE, 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.

[These web pages were originally written and updated by Ralph Milnes NM5RM, who is no longer active in packet radio. They were last updated in August 2015 which was about the time Windows 10 was introduced. There are no plans for him to further update the pages.]
