new FFT Filter setup and review web tool

Thank you so much for your assistance! I will analyze these settings and try to understand what I did wrong. Thanks again!

There was not much wrong, from what I remember you had too many harmonics and other options selected.
When using multi-source we set the bandwidth quite narrow.
There could be other problems with the copter that I didnt look into - I had a quick check for vibrations and roughly equal RPM of all motors, but not much else. You might need to start your own thread detailing the problems you see.

When if load this file

I get this message.

Can anyone explain for me why??

I believe multi-source should not be selected with throttle-based harmonic notch filter, or at least it would be useless. The message you see is just a warning via the web tool.
I believe you should be using ESC (RPM) based notch filter, not throttle-based.

The log still loads and the web tool still works OK.

Your motor poles seems wrong, so check exactly what motors you have, the specs will say something like: 36N42P
In that case you set SERVO_BLH_POLES,42

You can start with these settings for the notch filter and it should work fine once you set the correct number of poles.

BATT_FS_CRT_ACT,1
INS_HNTCH_ENABLE,1
INS_HNTCH_MODE,3
INS_HNTCH_REF,1
INS_HNTCH_FREQ,40
INS_HNTCH_BW,10
INS_HNTCH_FM_RAT,1
INS_HNTCH_HMNCS,3
INS_HNTCH_OPTS,6
INS_LOG_BAT_MASK,1
INS_LOG_BAT_OPT,4

EDITED for my poor typing

@xfacta Thanks as usual.
The motors are T-Motor MN601-S IP45 Multirotor Fixed Wing UAV Motor KV320
Configuration is 24N28P which I understand 28P/2 =14 poles??

no, just set SERVO_BLH_POLES,28 there is no divide by two.

Thanks for the clarification on that!!

Can I please ask where you got this value from?

In this graph it looks like the primary noise frequency is about 50 Hz , which matches closely enough with the props that I guess you have

With the ESC/RPM based notch filter we usually start with a lower frequency (to cover all situations) and the RPM data will scale up the frequency and the bandwidth to suit the actual RPM.
If you set that initial frequency too high then you miss out on filtering at lower motor RPM, such as descents.
Also the bandwidth is set to a quarter of the frequency when using the per-motor option.

Thanks.
I’ll set INS_HNTCH_FREQ,40

When I look at logs, it quickly becomes a “whole of copter” exploration, and so there is almost NEVER just one parameter to change. Check everything I wrote in order and carefully check every parameter I listed - just so you know.

Sure and will do. I just battling my way through the Methodical Configurator on a new build!!!
The problem is that some of the tools used display a lot of information but little explanation on how to use them.
