Among other great functionalities available on Anytone DMR radios, I just recorded how you can initiate a remote monitor and ranging request from one radio to another.
With ranging request, the receiving station is replying with a location. On a successful receive, initiating station either shows you distance/bearing between two radios or GPS coordinates of the second radio. If a receiving radio, that initiated a request, has a GPS lock, distance and bearing will be shown. Without a GPS lock, just a GPS coordinates of a remote radio will be shown. Of course, remote radio needs to have a GPS lock.
