Communication Modes- Digital

js8call

“The idea with JS8Call is to take the robustness of FT8 mode and layer on a messaging and network protocol for weak signal communication on HF with a keyboard-to-keyboard interface. JS8Call is heavily inspired by WSJT-X, Fldigi, and FSQCall and would not exist without the hard work and dedication of the many developers in the amateur radio community.”

WSJT-X

Description

WSJT-X implements communication               protocols or "modes" called FT4, FT8, JT4, JT9,  JT65, QRA64, ISCAT, MSK144, and WSPR, as well as one called Echo for detecting and measuring your own radio signals reflected  from the Moon.  These modes were all designed for making reliable, confirmed QSOs under extreme weak-signal  conditions.

Our Technology – What is System Fusion?


System Fusion is Yaesu’s  implementation of Digital Amateur Radio, utilizing C4FM 4-level FSK  Technology to transmit digital voice and data over the Amateur radio  bands. In the early 2000’s GMSK emerged in the Amateur radio market as  the dominant digital mode, however in 2013 Yaesu introduced “System  Fusion” which quickly became the dominating digital format in Amateur  radio because of quality, reliability and enhanced performance in a wide  range of environments.
