  708 B

is a Chinese backpack, used by artillery and anti aircraft artillery to build up an integrated firing net.
By linking two radios you can form a repeater.
It can be used as a field telefone up to a range of 2 km, and it can be remotely controlled by wire within 2 km.
A simple morse key is built in.
 
The radio comes in four versions, i.e. four frequency ranges:

  • 705 B : 36.0 ... 46.1 MHz
  • 708 B : 28.0 ... 36.5 MHz
  • 709 B : 21.5 ... 28.5 MHz
  • 714 B : 20.0 ... 26.0 MHz
     
    A close relationship between Russian and Chinese equipment can be seen: both use a kulikoff antenna, Russian and Chinese antenna rods are exchangeable. The antenna foot for mobile use also looks alike.

    Frequency range:
    28.0 ... 36.5 MHz (708 B)
