Baofeng UV5R Instructions

Baofeng UV-5R

There isn't really much information out there on the Baofeng UV-5R so I thought I'd do the best to document what I know so far.


Frequency range:
    [TX] 136 – 174MHz, 400 – 520MHz
    [RX] 136 – 174MHz, 400 – 520MHz, 68-108MHz (FM Broadcast)

Channel Memory Capacity:
    128 Channels

Channel Spacing:
    25KHz (wide band)12.5KHz (narrow band)

    =0.25µV (wide band) =0.35µV (narrow band)

Operation Voltage:
    7.4V DC ±20%

Frequency step:
    2.5, 5, 6.25, 10, 12.5, 20, 25, 30 and 50KHz


Antenna Connector: 
    SMA-Female / Antenna Impedance: 50 Ohm

Accessory Connector:
    Kenwood 2 Pin Standard


Output power:
    RF 5W / 1W
    Audio 700mW/10%

Charger Problem

The charger can sometimes be intermittent or stop working completely. I've found the cause of the problem to be in the design.
The DC socket is connected to the main board with Spring connectors (Un-Soldered) You can either clean the contact plates with a glass fibre
brush or by soldering jump leads to the main board resulting is a much more reliable connection.


You will need a proper Baofeng programming cable, as some of the Chinese ones use chips that are now incompatible with Windows.

For programming the radio I recommend the latest version of CHIRP available from danplanet.com
