You can set the step you want (both brute and fine) for any frequency range, even multiple values for different sections of the same band.
Example:
Code: Select all
; Frequency step per frequency range, in KHz, freq range in Hz
; format: FSTEP=<brute_step>/<fine_step>=<freq_int_min>-<freq_int_min>, ...
; brute - for +/-, fine for knob tunning
FSTEP=1/0.1=100000-87499999,100/5=87500000-107999999,5/0.1=108000000-
