Pakö ("to communicate" in the Bribri language of Costa Rica) is a free, open-source program for amateur radio digital modes: FT8, FT4 and the new JTTY mode. It is a simple, friendly alternative for operators who want to get on the air quickly: pick a station, double-click, and Pakö completes the QSO and logs it.
Version 2 adds JTTY (keyboard-to-keyboard, RTTY-style operation without time slots, using the engine from WSJT-X 3.2), editable macros, rig control through Hamlib, new/worked colour highlighting, PSKReporter spotting and an interface in seven languages.
Pakö is now released under the GNU GPL v3. Source code: https://github.com/ti5lx/Pako
Written by TI2LX, Costa Rica. Windows 10/11, 64-bit.
