Soft and Hard for PSK31

This is also the main distribution point for Peter G3PLX's  implementation reference software, known in it's Windows compatible version as P31SBW or PSKSBW. It is here but will also be able to get last english version requesting http://www.kender.es/~edu/download/p31sbw.zip

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

• There is a new free program in the PSK31 arena. It's named W1SQLPSK and it's coded by Joe Faria W1SQL. Along with the decoding of  20 signals at a time it also logs PSK contacts directly to a DBASE type file. It's available in the W1SQLPSK Homepage.
• There is a free program named WinPSK  (2.09) by Moe AE4JY. It removes several buglets from previous version 2.0.  Over version 1.0 it adds two interesting things, the first is a new user interface that favours disabled ham that cannot use mouse, through the use of Function keys and Macros. Latest version 2.09 adds full-duplex capability for Satellite use. The second one is that he has produced a PskCORE DLL (Now ver 1.10, which fixes problems with laptops and Windows Me) that is available in binary along with instructions to use it that let programmers develop PSK31 terminals without having to deal with DSP questions. I keep a local copy of WinPSK 2.0 binary, source and user manual in .pdf format.
• There is an Spanish help file for WinPSK 2.0 translated as usual by Paulí, EA3BLQ. It's here.
• There is a Japanese help file for WinPSK 2.08 translated by  Tsudaka Takashi, JA3VXH/KB7OBU. It's here.
•  I forgot a notable program for many time, because Nino IZ8BLY and Murray ZL1BPU work on MFSK was dominant on my mind when playing with this package. The name of the program is STREAM and it's available in Nino's STREAM page. Along with MFSK it offers variations on some PSK modes.
• After months of betatesting, here is the first public release of an amazing program named Hamscope by . It offers, several digital modes, as PSK31, MFSK, RTTY, ASCII, own HFSK16 and Morse, with a very graphic user interface. And it's FREE. What is a novelty in the PSK31 scena, is the additional FEC possibilities: TurboCodes, Golay, RS, etc. to test. It's worth a look  A very good work by  Glen KD5HIO, available at Hamscope Homepage
• The first non-beta version of Zakanaka (version 1.0) has appeared. It's coded by Bob Furzer K4CY, and it's available in  Zakanaka Homepage page.
• There is a new version of the amazing program Digipan 1.6d. It adds to it's panoramic view of the entire audio band, where you can instantly tune a new QSO with a click of the mouse, dual channel reception, selectable colors for all windows, ability to transmit and receive on different frequencies, easier to use log, QSO data display on status bar, phase scope, Sound history, and IMD measurement.  It's by Howard KH6TY and Nick "MixW32" UT2UZ.  You can get a copy from here, or from Digipan homepage. There is also an specific transceiver mad by SWL labs that will allow taking an snapshot of the actual IF passband. See details here.
• There is a new version of the program WinWarbler by Dave, AA6YQ. It's  based in PskCORE below and it can simultaneously decode and display PSK transmissions on three separate frequencies. It's present version is 1.9.2. You can take a look at it in Winwarbler homepage.
• There is a new program from VK-land named PSK-PAL. It is written in vb6  by Erik VK7AAB and is based on PskCORE.  It's able to monitor 3 channels at once. You can get it from PSK-PAL Download and take a look at it's associated egroup page.

• There is a new shareware program by UA9OSV TrueTTY that is able to transmit PSK31 and RTTY with a SoundBlaster. It's available here.
• There is a new version of  WinPSK,  1.2 by Moe AE4JY. It's features are impressive. Also it's the first fully GPL'ed windows and SB implementation, which means the source is available for free for non-commercial use. I keep a local copy of the binary, the source, the user manual in .pdf format and a technical supplement which is a must and real pleasure to read if you want to learn both implementation details and theory of operation. Also in .pdf format. Moe Homepage is here
• There is an Spanish help file for WinPSK translated as usual by Paulí, EA3BLQ. It's here.
• 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

Operating System Independent

• The last versions of the nice SCS PTC-II and PTC-IIe implement 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 Windowsprograms that are able to control the PTC-II

PSK31 by Hardware, or should I say, Hardware independent? ;-)

• George N2APB has prepared an Integrated and Portable PSK Station for 80 and 20 ... without using a PC! It's based ont the simple PSK transceiver boards from NN1G and Small Wonder Labs, along mith a Motorola EVM56002 . Characters are sent with a Morse Paddle. Details are available here
• After a year in the air the PIC based implementation of PSK31 by Clint KA7OEI, has been modified to allow serial control. He uses this setup for beacons on MedFer experimentation. Details along with sources for PIC programming are available here.
• Small Wonder Labs has just announced the PSK-20, a 20m transceiver kit designed for PSK31 that uses Digipan to take a glance at the IF passband. Details here
• Graeme Zimmer VK3GJZ has prepared a BaseBand PSK31 Decoder Module and is working in a project for a PSK31 Transceiver which uses a PIC16C877 processor to read from a standard PC keyboard and write to a 40 x 4 LCD screen that joined to his decoder a (to be designed) PSK31 Encoder Module. You can take a look at this work 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

... and some pieces of Hardware 
(for interfacing to Sound Boards)

• Dave deSouza G3VFP has prepared several SB to rig interfaces. They are optoisolated and available for several Rig brands. Take a look at Dave deSouza's interface Page.
• Timewave has a firmware upgrade (Version 5.0) for their DSP-599zx unit that between other things adds it a Soundblaster Interface and PSK31 filter capability. Check it here.
• KH6TY, Howard (Skip) Teller has recently developed a low cost Isolating Interface for SB. You can look at details here.
• 'Buck' Rogers K4ABT offers many possiblities to interface HF rig's to the Sound Blaster. Be sure to take a look at his PSK31 interface Home Page before plounging in a expensive purchase...
• 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.
• A spanish firm, has a SB interface that could be interesting for Spanish/European users, you can take a look at it here.
• There is also another unit by West Mountain Radio which is the RigBlaster.


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
