PSK31 Delphi Demo

This program, PSK31Test, is a demonstration of how to use the PSK31 Core DLL written by Moe Wheatley, AE4JY, in a Borland Delphi program. It is released for the benefit of those who would like to use Borland Delphi to develop PSK31 programs of their own. The DLL itself plus documentation may be obtained from Moe Wheatley's web site at


Note that since this program was written, several updates to the PSK31 Core DLL have been made, and some new DLL functions have been added that are not included in the examples. Please consult the PSK31 Core DLL documentation for more information. It should be fairly obvious how to add Delphi interfaces for the new functions.


Although the program is a functional working PSK31 program in its own right, it was only written to demonstrate how a PSK31 application could be written in Borland Delphi using the PSK31 Core DLL. The program is not intended for regular on-air use. This project is intended to be used by other programmers to create their own PSK31 software.


  • PC running Windows 95, 98, Me, 2000 or XP.
  • Sound card configured as default wave output device.
  • Borland Delphi 3.0 or later (to compile the source code.)
