• PyQSO is a contact logging tool for amateur radio operators.
• Xlog a minimal logging program for Amateur Radio Operators.
• GridTracker is a warehouse of amateur radio information presented in an easy to use interface, from live traffic decodes, logbooks, spot reports, weather, current solar conditions and more. (Used with WSJT-X)

Digimodes

• WSJT five programs designed for amateur radio communication
  • WSJT: Modes optimized for meteor scanner, ionospheric scatter, and EME at VHF/UHF/Microwaves.
  • WSJT-X: Modes JT65, JT9. Primarily for use at HF.
  • MAP65: For EME an VHF and higher frequencies. Implements a panoramic, polarization-matching receiver for JT65.
  • WSPR: Probe potential propagation paths using low-power transmissions.
  • WSPR-X: Experimental version of WSPR, including the slow mode WSPR-15.
• fldigi is a modem program for most of the digital modes used by radio amateurs today.

Libraries
