Is there a way to get more than 4 KHz rx bandwidth in USB or digital mode on my K3/ XV-144? I have the 6KHz, 2.8KHz, and 400z filters installed.
No. I have the 13KHz FM filter but the receive bandwidth is still limited to 4KHz.
I can appreciate that for use with PSK Browser software that decodes everything in the entire passband a wide bandwidth could be useful - just for monitoring.
However, if you can receive digital signals within a wide spectrum and can see them on the waterfall then the implication is that you can click on the trace and reply to them. On transmit, the audio still goes through the regular SSB filter. Therefore it is better to limit the bandwidth to 2.8KHz and limit the waterfall to about 400Hz - 2.4KHz within which the K3 properly set up in DATA A will give the full selected output. Then you won't be tempted to reply to stations that are actually outside the transmit passband.
