Digital Modes and CAT-Control

Amateur radio operators experiment with digital modes. Most require D-USB mode, except RTTY which uses D-LSB.

Software for Digital Modes

• FT8: Popular digital mode for weak signal communication. Frequencies provided for various bands.
• JS8: Derived from FT8, focused on personal messaging. Supported by JS8Call software (js8call.com).
• WSJT: Weak-signal transmission methods invented by Joe Taylor.
• WSJT-X: Free amateur radio software for weak signal communication. Configuration involves General (callsign, grid), Radio, and Audio settings. Enable TX manually to make a QSO. (wsjt.sourceforge.io)
• FLdigi: Cross-platform modem program supporting peer-to-peer digital modes. Requires a sound card. Available for Linux, OS X, Windows, FreeBSD. (www.w1hkj.com, sourceforge.net/projects/fldigi/)
• Dimension 4: SNTP client for precise PC clock synchronization, crucial for HF digital modes.
• GridTracker: Provides geographical overview of stations and links to WSJT-X. Available for Linux, OS X, Windows. (gridtracker.org)

Software for CAT Control

Many programs support CAT control. The Xiegu X6100 shares most commands with the G90. Baud rate for CAT control is 19200.

• Flrig: CAT control program usable standalone or with other software (fldigi, WSJT-X). Connects via DEV-Port. (sourceforge.net/projects/fldigi/files/flrig/). Configuration involves selecting 'Xiegu X6100' as device, correct COM port, and baud rate 19200.

Flrig and Fldigi are OpenSource and free. Contributions to gideons.org are appreciated.
