FM Transponder Ham Radio Satellite to Launch

The launch of the UVSQ-SAT satellite carrying an FM transponder is provisionally scheduled for 21st January 2021

The satellite designed by LATMOS had its frequencies coordinated by IARU. In addition to experimental and educational missions, it will provide the amateur radio community with a new FM transponder. AMSAT-Francophone and the radio club F6KRK have been involved throughout the project.

AMSAT-Francophone provides the amateur radio community with software to interpret the data and send it to the AMSAT-F & Satnogs database.

New WSJT mode Q65

WSJT-X 2.4.0 will introduce Q65, a digital protocol designed for minimal two-way QSOs over especially difficult propagation paths

On paths with Doppler spread more than a few Hz, the weak-signal performance of Q65 is the best among all WSJT-X modes. Q65 is particularly effective for tropospheric scatter, ionospheric scatter, and EME on VHF and higher bands, as well as other types of fast-fading signals.

Q65 uses 65-tone frequency-shift keying and builds on the demonstrated weak-signal strengths of QRA64, a mode introduced to WSJT-X in 2016. Q65 differs from QRA64 in the following important ways:

Digital Modes on any Android Device

droidstar for android is software which connects to D-STAR, DMR, Fusion, NXDN, P25, and M17 reflectors and gateways/repeaters over UDP. It uses open source vocoder software for all modes, and requires no AMBE hardware or silly remote AMBE servers. Dstar encoding is currently not acceptable for QSOs, so TX has been disabled.
