Is it possible to set the Global Filter Settings thru Sentinel? I know how to set the Global Filter directly thru the scanner. Would rater set thru the Sentinel software. Please help!

Here is a guide for setting filters in Sentinel and in the scanner:
SDS100/SDS200: - can i add or adjust individual filters for my sds100?
anyone know if theres is a way to adjust individual filters instead of just using global for all? example if im monitoring say tucson pd tucon fire and tucson medical each can have there own custom filter instead of what my global filter is set to?
“Filters can also be applied using Sentinel and then writing them to the scanner... use the profile editor for GLOBAL settings, and use the favorites list editor for INDIVIDUAL settings.”
Thank you so much!Here is a guide for setting filters in Sentinel and in the scanner:

To confirm:
You do know that the global filter applies to everything, right?
And that filters are used to correct a problem with an individual site or dept at a specific location?
And can/will adversely effect everything else?

If you set the global setting on auto, you will find your Favorites stalling. This is particularly true if you have conventional frequencies in your Favorites. I have the global set on "normal." You can change them at the system level if you like.
For larger cities, I find that setting "Site NAC Operation" to "Use Site NAC" speeds things up.
The decision-making process for the SDS 100 and SDS 200 can be adversely affected by filter settings. I learned this the hard way.

I found out by trial and error that by changing the GAF from "normal" where it's been ever since I got it to "off" GREATLY enhances the audio quality. It's almost as pleasant and intelligible as listening to a real P25 radio.
My question is, what ARE the values of the HPF and LPF (inverted HPF)? What's the wide option provide? Is it based on the frequency being scanned so dynamic? It seems that information is missing.

There are two SAW filters in the scanner, one at something like 250MHz and the other at something like 350Mhz. Which filter that are used depend of monitored frequency and if IFX are applied. The filters are at the 1:st IF frequency and are some 10MHz wide.
When you set the filter to be Off the monitored frequency are in the middle of the filters bandwidth, +/-5MHz. When you set Normal or Invert the monitored frequency will be at the very far end of the filters range, +0-10MHz and -0+10MHz. Choosing Wide will set the monitored frequency halfway to the end of the filters bandwidth, +3-7MHz and -3+7MHz.
If the filters where +/-1MHz there wouldn't be any problem, or a need to select filter settings, but there's no such filters available, or at least they would be more expensive than the whole scanner. Other Uniden scanners than the SDS series use the same type of filters but those receivers are of a much better quality that can handle the wide bandwidth of the filters but are also more expensive to manufacture but also lack the I/Q demodulator to properly handle simulcast transmissions.

Actually somewhat correct. Your Department/Site setting will override Global Filter settings unless the Department/Site setting is set to Global.
As an example, my statewide trunking system site(s) are set to Wide Invert, but I set the scanner's Global Setting to Normal. This will not change the statewide trunking system's setting, just any Department/Site that is set to Global.
Yea, I inadvertently omitted that (obvious) part - thanks. My point was to use the global setting with these points in mind. And that filters are all about location, location, location.
People new to all of this sometimes don't understand what "global" means - and does.
It might be "obvious" to those of us familiar with filter usage, to others new at this, not that much.
