I suspect this has been cpvered but I cannot find anything by searching the archives.
I am using WSJT-X v2.4.0 with an IC7610, controlling everything through the USB port.
Everything works fine, but I want to run the radio receiver at 3 kHz bandwidth instead of 2.4 kHz.
If I manually tap the FILTER button on the radio, I can select 3 kHz, but as soon as WSJT-X makes a transmission, the radio switches back to 2.4 kHz.
I am using the radio in USB mode, and tried the Data/pkt setting instead, which puts the radio in USB-Dx mode and none of those modes have a 3 kHz BW option (they are all even narrower than 2.4 and I cannot figure out how to make one of them 3 kHz)..
I suspect there is a simple way to do this a few menu steps down on either the radio or WSJT-X but I cannot find it.
Any ideas?
Thanks & 73,

Hi Doug,
if you have the "Settings->Radio->Mode->Data/Pkt" option checked then WSJT-X, via Hamlib, should be selecting USB-D (FIL 1) settings on you rig. Adjust the USB-D1 bandwidth on you rig to maximum. I am not sure if bandwidth settings are recalled per band, if they are then you may need to adjust FIL 1 in USB-D mode for each band you use.
Page 4-4 of the English Basic Manual for the IC-7610 seems to cover IF bandwidth setting. You can set the filters up to 3600 Hz wide in SSB modes like SSB-D
