I have just made a spreadsheet anyone can edit to see what is the best setting for each system. This is for the SDS 100 & 200.
SDS 100 & SDS 200 Global Filter Settings
SDS 100 & SDS 200 Global Filter Settings
Your Global setting is Global ?

The Global setting does not have an option for Global. Only Normal, Inverted, Auto.
My present understanding is:
Global – Whole Radio (Normal, Inverted, Auto)
Site – A Specific Trunked system Only (Normal, Inverted, Auto)
Department – A Specific Conventional Channel Only (Normal, Inverted, Auto)
Of course Site & Department can be done in conjunction with Global.
Is this Correct?
What does changing the filter settings actually do? Inverted VS others, etc?
My personal experience with the different filters is they have made a difference in many of my analog systems that were suffering the rf intermod issues. I had to move much of my analog scanning back to the 536 for awhile, but after making filter adjustments, was able to return my analog back to the SDS200. The only systems I still can not monitor consistently is a low power DMR and NXDN systems which the filters made no difference. The SDS200 can't pull these out well enough unfortunately.
Which filter settings did you use on analog? I'm seeing the biggest problems in the 460-480MHz range. I tried all of the different filters and I'm not noticing any difference.
I had trouble with 462.950 set the filter to wide normal with the IFX set to on and the difference was 100% improvement.Which filter settings did you use on analog? I'm seeing the biggest problems in the 460-480MHz range. I tried all of the different filters and I'm not noticing any difference.
I would pay $150 more without blinking for what would be an SDS200 with some switched bandpass filtering. At home, in my apartment, the stock SDS has no real problems, but if I put it in my car, there are intermod issues galore, and desensitizing too. A friend of mine was thinking about buying an SDS200, but when I took mine over there failed miserably mostly due to being slammed by a nearby business, and a not all that close FM station is in the mix on some frequencies too Even just adding an FM broadcast filter would be a huge help, but it still needs more help. Until then, his Pro 197 soldiers on.
