SDS100/SDS200: Global Settings

[XPS720]

The other day I noticed that my DMR's were getting no signal and very little receiving on non-trunk. It took a while to spot it but I noticed G-ATT on my SDS 200. I went to Sentinel program-Edit Profile-miscellanies-and Global Attenuate was set to on. Turning it off did solve problem. Not sure how but it all started after I did Monday update. My question is what are proper Global's on the 536HP/CLMR and SDS200/DMR for Trunk listening.

Thaank you

There is no proper setting as every ones environment and variables will be different.

Updating the master database should not cause the radio to default to factory filter settings. But if it did, and you returned it to your previous CPS you should be fine.

Experimentation is key. Personally with my SDS100 I keep the global filter set to Normal unless I'm trying to bring in more distant systems/sites and in that case I change said sites' filter setting to "Invert" which I found works best for the weaker stuff, YMMV. Reference this PDF for a brief filter overview

Also the x36HPs have a different nomenclature for this setting & this is commonly adjusted to try and mitigate the effects of simulcast distortion
