andrandr Yes, it is possible in GPS mode. You should pre-tune all radios in your workgroup and use the equal frequency. In GPS mode set to some station in your group and shortly click TX-button. You ask GPS - coordinates of chosen station and send yours simultaneously. You will see the GPS position of asked station marked by white dot in a circle, and your position will be always in the center of the circle, marked by the red dot. The top of the vertical line is always directed to the North, not to your antenna. Distance to asked station is in accordance to the distance of a white dot from You, red dot. To see where are the other stations, click buttons up or down. .
