In you video you are doing a VFO scan, so all kind of signals may appear in that frequency range,
the GD77 will lock on those signals and because they may be anything else, but not a DMR transmission,
no audio will be heard. Are you sure, it locked on a DMR signal?
And if you try to chase & listen to other services (legal ?), all kind of encoding can exist.
OpenGD77 supports FM and DMR dual time slot Tier I and Tier II
Program a known DMR repeater frequency pair in CPS, upload the codeplug to the GD77 and try to listen on such a channel.
Install 'RepeaterBook' or 'RFinder Worldwide Repeater Dir' on your mobile, so you will find the nearest repeater in your area.
Besides this, this app will show you if they are DMR, D-Star or C4FM - and only FM & DMR can be heard with OpenGD77.
It will work - straight forward, without any problems. As you said: 'understand?'
