Use "Auto".
The 2.4 kHz filter used in addition to a similar DSP filter will
significantly reduce the bandwidth. Measured bandwidth is 2.174 kHz
at -3 dB, and the filter is practically flat to ~ 2.0 kHz width.
Using 6 kHz filter will not be a handicap until a very, very strong
signal appears next to one at the noise level, by by then you'd
certainly narrow the bandwidth and 2.4 kHz filter will become
engaged.
