Radioddity GD-77S is a series product of GD-77. “S” stands for “Standard”. Without LCD screen, the newly added button makes it easy to switch between channels, and the voice prompt function helps you know all the frequency details.

All these are to make a “standard” and easy operation radio which can turn on and use directly.
