Amateur Radio data mode ROS - YouTube video

A YouTube video shows ROS the new digital mode designed for HF, Meteor Scatter or Moon bounce working

Developed by José Nieto Alberto Ros the first HF contact using the mode took place on February 18 and the first moon bounce contact, between SV8CS and DL8EBW, followed a few days later on February 22.

The software has two Symbol Rates: 16 and 1 baud (the latter aimed at weak signals down to -35 dbs of S/N) and can automatically synchronize any Symbol Rate.

It is still in Beta state so users should ensure they are running the latest version as José has made a number of improvements in the lst week.
