HamScope v1.56, released on 2007-03-20, functions as a multi-mode communications interface for amateur radio, supporting digital modes such as PSK31 (BPSK and QPSK), RTTY, ASCII, MFSK16, PACKET, and CW. The software integrates with external engines like _MMTTY_ for RTTY/ASCII and AGWPE for PACKET operation. It features a panoramic waterfall display, 42 user-programmable macro buttons, and user-definable function key mappings, providing operators with enhanced control during digital mode operations. The program includes a radio control interface compatible with several ICOM, TenTec, Kenwood, and Yaesu transceivers, enabling direct rig control. HamScope also establishes data links with various logging and radio control applications, including LOGic 7/8, DXbase 2004, RYLogit, and TRX-Manager, facilitating seamless data exchange and logging. A DDE server is available for custom connections. Designed for Windows 98 and NT, HamScope requires a 133 MHz Pentium-class machine and 16-bit SVGA color. While not officially supported, users have reported functionality on Windows 95, ME, XP, and 2000, though some issues with window settings or the MMTTY engine may occur. The software is distributed as a single executable file, with separate downloads required for MMTTY and AGWPE engines.

Grig is a freeware simple Ham Radio control (CAT) program based on the Ham Radio Control Libraries (Hamlib). It is intended to be highly generic presenting the user to the same graphical user interface regardless of which radio is being controlled. Grig supports the most commonly used CAT commands that are implemented by Hamlib, and integrates well with other ham radio programs like Xlog and gMFSK. Grig has been developed on Linux, but has been ported on Mac and Windows OS.

AirLink Express is a user friendly digital mode software package for the Amateur Radio Operator. The software is compatible with Microsoft Windows XP and Microsoft Windows Vista. It offers PSK, MFSK and RTTY digital modes with logging and macro capabilities. If you have ever used the Digipan software you will be immediately familiar with Airlink Express. The user interface is almost identical by Alex Krist, KR1ST

EXTFSK.DLL is an MMTTY extension that interfaces MMTTY to a user-made hardware device via serial port, parallel port or USB

Easy to build RS232 keying interface for FSK and CW. Works with most popular RTTY software like MMTTY. Also works for with most contest software such as N1MM and Writelog for CW keying. Uses the RS232 port RTS, DTR, or TX data, optically isolated, PC boards available.

Interface board was for connecting Yaesu FT-817ND transceiver to Android phone or tablet. The board was developed for experimenting with RTTY, SSTV and other digital modes using DroidRTTY, DroidSSTV and other software on an Android phone.

The sudden explosion of new digital modes has taken the Amateur Radio world by storm. New modes such as PSK31 FT8 JT65 FSK441, ISCAT as well as established modes such as RTTY, SSTV, Hellschreiber and others have rocketed in popularity. In order to use these modes all that is required is a simple computer-to-radio interface which couples the computer soundcard to the radio

Ground Station offers real-time satellite tracking and radio communication capabilities, primarily for amateur radio operators engaged in satellite operations. It utilizes **TLE data** from sources like CelesTrak and SatNOGS for precise orbital prediction and integrates with various SDR devices, including RTL-SDR, SoapySDR, and UHD/USRP radios, to receive live signals. The software provides automated antenna rotator control and **Hamlib-compatible** rig control with Doppler correction, crucial for maintaining signal lock on fast-moving LEO satellites. It supports IQ recording in SigMF format and decodes several digital modes such as SSTV, FSK, GFSK, GMSK, and BPSK with AX25 USP Geoscan framing. Dedicated interfaces are available for satellite tracking, SDR waterfall displays with live transcription and packet decoding, and telemetry packet viewing. Users can manage TLE data synchronization and SDR hardware, along with browsing decoded outputs through an integrated file browser. An observations dashboard and DSP topology view further enhance the operational experience, providing comprehensive tools for monitoring and analyzing satellite passes.

The N7YG Digital Engine, functions as a streamlined digital modem, supporting **PSK**, **RTTY**, and **MFSK** modes. It eliminates many ancillary logging and awards features found in other software, focusing instead on providing a dedicated digital interface. The software is specifically engineered to complement the N3FJP logging suite, offering a simple digital modem with a floating waterfall display that can coexist on the same screen as the logger. The application includes support for PSK Reporter, EXTFSK, TinyFSK, and K1EL Winkey FSK, enhancing its utility for various digital operations. Key features comprise a separate waterfall window, a main GUI with operational controls, receive and transmit display areas, and 10 Macro Buttons across 10 user-definable macro banks, totaling 100 macros for general and contesting use. Configuration options include sound card selection, digital gain (0-32767), AFC Level (0-100), AFC Width (in Hz), and COM Port TX keying for VOX/SignaLink or direct port control. Input and Output Mixer buttons provide direct access to OS audio mixer controls for precise level adjustments. The software is digitally signed with a security certificate, aiming to prevent conflicts with antivirus programs.

This presentation offers a beginner's guide to digital communication modes in Ham Radio, specifically PSK31 and RTTY. It covers the basics like what data modes are and the equipment needed (radio, computer, interface). It explains the technical details like PSK vs. RTTY, AFSK vs. FSK, and data transmission processes. The presentation also provides instructions on software setup, live testing procedures, and where to find data transmissions on different bands. Finally, it covers communication styles and etiquette for data QSOs.
