PSK31 - Phase Shift Keying

What is PSK31 you may ask?

Translated literally, it's an acronym for "Phase Shift Keying, 31 Baud".  PSK31 is a form of modulation (or "mode") that offers a new and higher level of performance in conversational communications (keyboard-to-keyboard) that we as amateur radio operators can enjoy.  It is instantly usable to most of us due to that we own a personal computer.  BUT most of all without the generous efforts of some very talented ham/programmers we would not have this most fascinating version of Ham Radio. .

PSK31 has grown in popularity very quickly.  Some say it could replace RTTY as the main keyboarding mode.  It's easy and fun to work with.  It is well worth your effort to check it out and see what is is all about.   Who knows what combining computers, Ham Radio and Talented Programmers will produce next! Thanks to the programmers and their generosity as a lot of the software is FREE!

Below you will find some popular PSK31 sites.  Hopefully this will wet your appetite as it has mine. 73 & Good Luck!

Where can I find the Software?

• WinPSK (by AE4JY) -  Source code for the application is provided too.  Best of all it is FREE! Click here for more info.
   
• "Zakanaka" by Bob Furzer, K4CY (Logger author). Be sure to follow up on Bob often.  He constantly comes out with new versions. He works hard at staying at the forefront of PSK31.  Click here for more info.
   
• Logger by Bob Furzer, K4CY.  Please note that it works side by side with  Zakanaka releases.  Logger allows you to control your rig, control your rotor and other various things. Very nice & FREE as well!  Click here for more info.
   
• New version of WinPSKse (1.4), it's getting VERY NICE. Download here  and try it!
   
• DIGIPAN stands for "Digital Panoramic Tuning" and brings the ease and simplicity of PANORAMIC reception and transmission to PSK31 operation. DigiPan provides a panoramic display of the frequency spectrum in the form of an active dial scale extending the full width of the computer screen. Depending upon the transceiver IF bandwidth, it is possible to "see" as many as 40 to 80 PSK31 stations at one time.  Click here for more info.
  
•  AALog is a comprehensive logger program designed for amateur radio station operators. It has convenient interface, good set of tools, fast and very easy in use. It looks like your paper log an use all power of your computer. It is able to be integrated with the CW terminal program CwType, morse decoder CwGet and RTTY/PSK31 software TrueTTY 

The plan for PSK31 activity has always been (since PSK31 started) to concentrate activity starting from the bottom edge of the IARU RTTY bandplan, expanding upwards as activity increased. The exception is in the 10mts band in order to give non full privileges ham to meet. It was defined as 150 Hz above it. Keep in mind that all you need is about 100 Hz as channel separation.  (NOTE: Frequencies may vary a little depending on the software you are using).

1838.150
3580.150
7035.15 for region 1 and region 3, and 7080.15 for region 2 *
10140.150
14070.150
18100.150
21080.150 (although most activity can be found 10 kHz lower)
24920.150
28120.150

* This is due to the fact that the 7 MHz band is much wider in region 2 (the Americas), and the IARU bandplan reflects this.
