The 6KHz (or 13 KHz FM) filter will do an indicated 4 KHz width with 2200 Hz center for a bandpass of 200-4200 Hz. I do it all the time.
The reason I do not use 2000 Hz center is that the K3/K3S DSP rolls off at 200 Hz (there is an option to set the LF response lower but I prefer the 200 Hz cut off for SSB otherwise). 73, ... Joe, W4TV On 6/6/2024 7:50 PM, K4PI.Mike Greenway wrote:
I recently got a K3S with a 6 Khz filter. Previously had just a 2.8 for DATA which would go to 3.20 Width and 2.60 Freq Center. With the 2.8 deselected in the Config menu and only the the 6 KHz selected for Data I can still only go to 3.20 Khz Width and 2.60 width. On AM I can go to 5 Khz Width and 1.70 Freq Center. Why am it not able to do more width with the 6 Khz in DATA mode? I want a wider filter in DATA than the 2.8. Appears the 6 Khz only helps me in AM. Am I missing something here or the K3 just does not allow wider width in DATA. Any thoughts appreciated. 73 Mike K4PI
