Nec2Go - Powerful antenna modeling tool using NEC 2 computing engine. Nec2 specifically provide users, either those experienced with the Nec2 processes, or for those who are neophytes but want to model their own antennas. Nec2Go uses a simplified process for defining the antenna structure and then providing view of the structure, plots (2D and 3D) and other significant data that is pertinent to the design. This simplified process uses an edit file with equations for all definitions.

Scancorder - With Scancorder you can record and replay audio from your scanner using your computer soundcard. The audio is recorded digitally as a wave file, so that even digital modes can be re-processed or analysed later.

AFU Knoppix - The AFU Knoppix CD contains software for the operating modes of PSK31, RTTY, SSTV, FAX, APRS and packet radio. Additional applications for Sat tracking, logging, locator referencing and antenna computation are also included. The CD is targeted for radio enthusiasts, the Linux operating system and the applications on this CD are structured so that they can run from the CD without effecting the installed existing system software. *
