Demonstration of sliding frequency changes
A fun and useful demonstration of the capabilities of QMX and the Input Analysis application, is to
investigate the FT8 tone change transition. We know according to the WSJT-X documentation that
to avoid splatter onto adjacent frequencies, WSJT-X makes a smooth transition between one tone
symbol and the next. It’s nice to be able to check this using the Input Analysis screen.
