Scope - Yaesu FT dx 1200 Operating Manual

This function displays a convenient spectrum scope for monitoring the band conditions. Both strong and weak signals
can be displayed in an easy-to-understand manner on the TFT screen. This multifunctional scope takes into consid-
eration the operator's preference, by switching between the convenient CENTER mode where the VFO frequency is
constantly in the center of the screen (for monitoring conditions on both sides of your operating frequency), and the FIX
mode, where the frequency is fixed to the left side of the screen (for convenience in monitoring in the band).
