DM780 has the center function and it works fine so I dont miss any
manual shift functions.
I have defined the following two macros:
#++
# Center & narrow macro
# {{RADIO-CONTROL
#
# This macro only contains commands for tuning your radio.
# The text is not added to the input (TX) window.
#

center-on 1500
Set slider-pos K3 Filter~Width 30 // Filter Width = 300Hz
#++
# Wide macro
# {{RADIO-CONTROL
#
# This macro only contains commands for tuning your radio.
# The text is not added to the input (TX) window.

Set slider-pos K3 Filter~Width 400 // Filter Width = 4000Hz
I have set the 250Hz filter to kick in at 300Hz.
