Re: DMR Scanning, Private Calls and Talkgroups

additionally, if its a repeater/trunking output frequency, there's simple a lot of technical traffic like beaconing that cant be decoded into anything meaningful unless you're debugging network issues with dedicated gear.

Re: original firmware copy

First. search on the manufacturer website, otherwise you'll find many information in the dedicated forum section. Are you sure about the DM-1801 and it's not a BF-1801 (FW version looks suspicious)?! both DM- and BF- seem to sell in the same box and the only difference is their hw revision it seems

I discussed this with a technician who repairs Motorola DMR radios, and the radios have a special "Test" mode where they transmit a carrier with no DMR pulses etc, so that the technician can test the power output i think it would be something like ...
