DFIlter passband width setting (SSB/CW/RTTY/AM only)

q Select SSB, CW, RTTY or AM mode.

 

 

•Passband widths for FM and WFM modes are fixed

 

 

and cannot be set.

 

 

w Select M-1.

 

 

•Push and hold [MENU/GRP] for 1 sec. once or twice

 

 

to select the menu group M.

 

 

•Push [MENU/GRP] momentarily one or more times to

 

 

select the menu M-1.

r Push [F-3FIL] several times to select the desired

IF filter.

t While pushing [F-1BW], rotate [DIAL] to set the desired passband width.

•The passband width can be set within the range as shown in the table to the right.

•Push [F-2DEF] for 1 sec. to select the default value.

y Repeat steps r to t if desired.

u Push [Z(MENU/GRP)] to exit the filter set mode.

The PBT shift frequencies are cleared when the passband width is changed.

This filter set mode screen graphically displays the PBT shift frequencies.
