Chat on the Air with LinPsk

The original international electronic hobbyist community is ham radio. Here are the basics of the chat room without the room.
Future Plans

When beginning work on LinPsk, my objective was to learn C++ and to develop a PSK31 program for Linux that was easy to use. KDevelop was a great help for me during this development. Meanwhile, I implemented RTTY as an additional mode. This mode works, but the decoder part should be improved. At that point, I tried to modify the code to get a framework for implementing different digital modes. I tried to implement MFSK16, but that mode is not functional as of yet. So this is another point for future developments.

I was asked to port LinPsk to Mac OS X. That was an interesting challenge and thus DarwinPsk was born. At the moment, my development platform is a dual-boot iBook with Mac OS X and Gentoo Linux. All examples were taken from the Gentoo Linux part and KDE 3.2. Now I maintain two distributions and receive many proposals for improving the program. Of course, I receive bug reports as well. The latest documentation was version 0.6, dated January 2002, so something new is needed. Help is welcome in the form of writing user-oriented documentation, testing the program or making proposals for improvements or reporting bugs. Even implementing new modes or writing is possible. Improving existing programs or designing new modes fits well with the experimental nature of amateur radio. And, believe me, the ideas of open source fit the spirit of ham radio.

Dr Volker Schroer came into contact with Linux in 1995 when setting up a firewall. Becoming a ham in 1996, he started developing LinPsk in 1999. Comments and proposals are welcome to
