SPLIT operations - bandwidth receiver B very narrow

If SPLIT is activated, the bandwidth of receiver B is very narrow, to solve the problem I have to change the bandwidth
I’m using 8400 firmware 4.0.1
Has anyone encountered this strange behavior?

    After some testing, I found that the problem also occurs when the second receiver (slice B) is acticvated. It can be solved by deactivating NR from slice A or changing the BW on slice B.

    • band?
    • Mode
    • filter settings before you go split

    It helps us to recreate the issue.

    Hi Mike,

    • band: 10 to 20 m, I haven’t tried on low bands

    I am not able to recreate this on 4.0.2 (99% of 4.0.1). Can you try a radio reset and see if the problem still exists?

    Since Eric is testing it, I will not duplicate his effort. Let us know how you make out.

    HI Mike,

    I guess the problem might be related to the NR, I’m using a basic NR
