Monitor USPS?

Is there a ways to find out if its a talk group? Would that be found in a Search?

As Dave indicated, first you need to SEARCH and see what is around you (what you can actually hear)
some of those Sorting Facility trunks are designed to ONLY cover the Bldg/Property, so you may need to be nearby

Spend a few weeks, searching/logging first, bring the list back here and share, see what you've found

Why stop at 408? The federal land mobile radio band is 406.1-420 MHz.

I scanned these, and I did find some on my SDS200, but I'm getting that jackhammer sound too. Which I don't understand, because I did get the DMR upgrade. Is this another digital mode??

And what Freq did you find, that you think is DMR ?
