Setting Value
Auto (default)/ 270/ 500/ 2.7 k/ 6 k/ 15 k [Hz]
Auto: A roofing filter with a bandwidth wider than the passband
width of the DSP filter is automatically selected using high
cutoff/low cutoff or Width/Shift. (If there are 2 or more
bandwidths that satisfy the conditions, the narrower one is
selected.)
In the AM mode, a 6 kHz roofing filter is automatically
selected if the high cutoff frequency is 3 kHz or lower, and a
15 kHz roofing filter is selected if the high cutoff frequency
is higher than 3 kHz.
In the FM mode, the option is fixed at 15 kHz and cannot be
changed.

YG-82CN-1 is attached.
Pressing and holding F3 [ROOF] each time switches the
options in the reverse sequence.
