Twpsk was written by Hansi, DL9RDZ and myself. It is a soundcard based program that lets you run PSK31, the digital mode designed by Peter, G3PLX. It offers narrow signal width and gives excellent results with low power and minimal antenna systems. In short, it's the best mode to come along since spark gap!

Uses the latest psk31 engine from Hansi, DL9RDZ.


Seek feature automatically tunes up or down the band to the next PSK signal.


Sends text from files. Text files can contain "place holders" which allows you to enter variable information, like contest numbers and signal reports.


Lets you create your own macro keys.


Copy up to 4 QSOs at once.


Interfaces with log programs - currently twlog and xlog.
