This is a problem that has been bugging me for sometime. I finally decided to look into it.

I am running an IC-7300 and connecting to it with flrig. Most times I change my operating from CW to FT8 the filter bandwidth remains at 500 Hz. I am using WSJT-X to effect the switch. I have found the trace where WSJT-X is requesting the mode change and can see the XML and CAT interfaces. In the section below I see 4 CI-V transactions:

at 681 ms - On selected VFO, set USB-D, filter 1.

at 684 ms - Set bandwidth 9 - which I assume is what is setting it to 500 Hz (0 is 50 Hz, 40 is 3600 Hz).

at 686 and 689 ms - these are setting default Twin PBT settings.

Should we keep the bandwidth when we change modes or just keep the selected filter or even select the default filter for that mode?
