Under the PTT button there are two side keys on GD-77. You can use programming software to customize them as hot keys based on your needs—Emergency On/Off, Scan On/Off, VOX On/Off, Repeater/Talk around, Zone select, etc (Up to 20 options). Once set, those features can be easily achieved when you press and hold or press and release the side keys.
Up to 5KM (3 Miles) Talking Range
Although GD-77 is only 3CM in body thickness, the talking range can be as far as 5KM (3 Miles) under most circumstances. There are other factors that affect the range of a two-way radio too such as weather, exact frequency used, and obstructions.
Please note that extended transmit time may lead excessive heat, affecting the battery lifespan.
