Soft and Hard for PSK31

There is much software for getting in the air on PSK31. You can choose based on the Operating System of your computer and after that based on the hardware you have. You should read the notes for the compatibilities between DOS and Windows versions.

DOS

• Motorola EVM Version by Peter Martínez G3PLX, now with on screen waterfall display : p31evd302.zip
• Texas C50DSK Version by Andrew Senior G0TJZ. Now compatible with Peter's latest release for DOS: psk31c50_r2.zip
• Adaptation of Peter's psk31evm301 for 56002 based EasyDSP DOS Version by DF6JB: psk31eas301.zip
• OH2GI-HAM SYSTEM is a DOS commercial terminal that supports the SCS PTC-II in PSK31. You can read about it in Here
• Intercom is a free DOS program by Pier PA3BYZ that since version 4.1 adds PSK31 capability to many other modes. It can use several interfaces, hamcom type, soundcard, etc. It's homepage is here

Windows

• New version (1.2) for SHARC EZ-Lite EVM that adds to the "standard" modes variable transmission-speeds (PSK16-124 ) with stronger QPSK modes up to constraint length 9. Now it also has IQ input/output for direct connection to IQ UP/DOWN mixer (integrated hilberttransformator). It's for free. By Michael DL6IAK: mpskwiq
• RCKRtty Is a Windows Terminal capable of working PSK31 with SCS PTC-II and DSPCOM units.
• New version (1.08) for Windows 3.1, Windows 95/98, Windows NT with Soundblaster. (At least a 486/33, perhaps less with slower rates). With Soft-decision Viterbi, better squelch, and a much better AFC. Now with Slash-0 configurable on reception. There is a new feature which will help users to give accurate and useful signal quality reports to other PSK31 users. By Peter G3PLX :p31sbw108.zip
• There is a new Spanish Windows Help File for the Windows SB version 1.08 translated by Pauli EA3BLQ . It's here: p31sbw108-es.zip
• There is a new Russian Windows Help File for the Windows SB version 1.06 translated by Mike RV3DBL and Andrey RA3DOA . It's here: p31sbw108-ru.zip
• There is a new Czech Windows Help File for Windows SB version 1.06 translated by Petr OK1FCJ and Pavle OK1DX . It's here: p31sbw106-cz.zip
• There is a new Polish Windows Help File for Windows SB version 1.06 translated by Marek SP7DQR. It's here: p31sbw106-pl.zip
• There is a new Italian Windows Help File for Windows SB version 1.07 translated by Eduardo Alcolado I5PAC, and assembled in .HLP format by Pauli EA3BLQ. The file is here
• There is a module for the Analizer 2000 program that implements a PSK31 modem. It uses Soundblaster. Take a look at it here
• WriteLog is a Windows program by Wayne Wright W5XD that seems to offer a PSK31 module over Soundblaster. Take a look at it here
• Motorola EVM 56002 Windows with help, tunnig aids, and a waterfall indicator for easier tunning and a receive overload indicator. New version with Soft-decision Viterbi, better squelch, better AFC. Now upgraded to include a decibel readout of the intermodulation distortion on received idle signals. By Peter G3PLX.: p31evw125.zip
• MixW32 is a new (now on version 1.03) Windows/SB commercial program by Nick Fedoseev, UT2UZ. It supports among others PSK31 in PSK and QPSK and a new mode named FSK31. You can get it here. Here is it's Homepage
• Logger is a free program that (between many others options) has PSK31 direct support with a Sound Blaster, starting from version 6.07. You can take a look at it at his Homepage.

Linux

• New version (still Beta) for Linux + Sound Blaster by Hansi Reiser DL9RDZ. Please see details for compiling and using at his Homepage. Old is still here: psk31lx-0.5.tgz
• There is a X-Windows version of the previous program by Ted WA0EIR, that is available as twpsk-0.6.tar.gz.

Macintosh

• There is a shareware program called Multimode by Chris N3JLY that starting from version 2.1.0 is able to do PSK31 on RX/TX for macintosh users. You can take a look at it's Homepage

Operating System Independent

• There is a new firmware (V2.7) for the nice SCS PTC-II and PTC-IIe that implements a PSK31 terminal, that you can use with any communication program as:

  • Simple Terminal is a windows program that only works with PTC-I and PTC-II TNC.
  • There are other DOS and Windows programs that are able to control the PTC-II

Should I say, Hardware independent? ;-)

• There is a PIC based implementation of PSK31 by Clint KA7OEI, that he uses for beacons on MedFer experimentation. Details are available here.

Various pieces of software...

• There is a free frontend program for P31SBW by Al WD5GNR that implements features that some people find missing in Peter's program, as typeahead buffers and macros. It's homepage is here. Soon I'll mirror the files here.
• There is package by Wayne Wright W5XD (Writelog's author) that contains some C++ classes that implement the DSP algorithms invented by Peter for PSK. It also has a DOS test program that demonstrates their use. It's here: pskcppsrc.zip  

  Notes

  • Every version can transmit 255 different varicode symbols,and map these to values in the range 0 to 255 for display as characters on the screen.This means that PSK31 is now capable of handling some of the less-often-used symbols and special accented characters that are not in the standard 128-character ASCII character set. The problem is that the mapping between the values and what is presented on the screen is not coherent between DOS versions and Windows Versions and even between DOS versions with different Codepages loaded.
  • EVM versions now use the same CLD file which runs the DSP software in the board. These versions also, can now be used, along with suitable hardware, to build a complete direct-conversion PSK31 transceiver. This should be of interest to home-contruction fans and those experimenting with VLF bands 

... and a piece of Hardware

• Salvador Esteban, EB3NC produces and sells an interface for the SB cards. Shippings to Europe and Spain should be more interesting than from USA. Find details in english here and in spanish here
• Mike WA8TXT produces and sells an interface for the SB cards that I wouldn't mind to test. Find details here
