Split Operations - When and How - An interesting guide on operating in split mode

About digital modes - The digital modes provide a wonderful opportunity for those of us who would like to work on the HF bands but find CW too difficult and SSB phone prohibitive because of interference problems. The digital modes are easy to set up and get operating, require low power and a narrow band.

Konfabulator - DX Cluster Priority listing - Freeware windows XP and MacOSX konfabulator widget dedicated to Amateur radio operators, is an easy interface to DX-Summit the ham-radio DX Cluster. DX cluster spots represents live ham radio communication connections, and are an invaluable resource for amateur radio operators. Users can choose Bands or operating modes like digital emissions, QRP IOTA and more. Spots are refreshed automatically and refresh rate can be set by users, with a minimum of 100 seconds.

CQiNet, linking Ham Radio - CQiNet is a family of programs that combine Ham Radio with the Internet using Voice over IP (VoIP) technology. Two programs are currently in the family, "theBridge" and echoLinux. Thebridge is a iLink/EchoLink compatable conference bridge that runs under various versions of Unix as well as Windows. EchoLinux is a EchoLink client program for the Linux operating system.

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. *

Turbolog - TurboLog is a station management and logging program for the discerning radio amateur / hamradio operator. Besides powerful database and logging functions there is a fully integrated support for the control of typical radio station equipment, e.g. Transceivers, Packet radio, Morse and voice keyer, Digital modes terminal, Antenna switching, Acoustic alerting, and more

MMvari - MMVARI is a multi-Mode SoundCard Ham (Amateur) Radio program for receiving and transmitting the RTTY-PSK-FSK-MFSK modes. The program was written to experiment with the efficiency of transmitting Japanese and East Asian languages (HL/BV/BY) using the VARICODE

G7RAU Live MUF V7 - Live MUF is a DXC (cluster) telnet client which attempts to resolve propagation modes from spots and also attempts to calculate sporadic e possibilities purely based on incoming data from the cluster

Predict - Satellite Tracking/Orbital Prediction Program an open-source, multi-user satellite tracking and orbital prediction program written under the Linux operating system by John A. Magliacane, KD2BD. PREDICT is free software

Gpredict - Gpredict is a satellite tracking program for Unix-like operating systems. In the begining (v. 0.1.x) Gpredict was just a GUI client to John Magliacane's excellent satellite tracking program, Predict, but due to performance problems it has been decided to include the tracking code directly into Gnome Predict (v. 0.2.0 and later).

SpectraScope - SpectraScope is a simple Windows interface program allowing your computer to view up to two audio waveforms in either the time or frequency domain. The program is a Windows soft panel operating as a dual channel oscilloscope and spectrum analyzer. The useful frequency of operation is 20 to 10,000 Hz in the time domain and 20 to 20,000 Hz in the frequency domain. The program uses the computer sound card to capture the audio input.
