Radio Code

Every field has its own technical terms and vocabulary. You can see a lot of "buzz words" or terms in BAOFENG radios' manuals and descriptions on websites. Here we would introduce the most commonly used technical terms and show their meaning in simpler English.

 

Abbreviation

 Full Name

Description

ABR

Display Illumination Time

Time-out for the LCD backlight(seconds), usually 0-10s.

AL-MOD

Alarm Mode

• SITE [0]: Sounds alarm through your radio speaker only
• TONE [1]: Transmits a cycling tone over-the-air
• CODE [2]: Transmits ‘19’(911 in reverse?) followed by the ANI code over-the-air

ANI-ID

Automatic Number ID

With this function, you can set your ID code. It can be programmed by the proper programming software. The number of max digits is different from radio to radio.

AUTOLK

Auto Keypad Lock

When this feature is activated, the keypad will be automatically locked after 15s; this prevents accidental pressure of any keys.
The keypad lock can be manually activated/deactivated through the keypad: keep pressed [#].

BCL

Busy Channel Lock

When this function is on, it may prevent other radios’ interference. If the selected channel is being used by other radios, when you press key PTT, your radio cannot transmit.
Release the PTT and transmit as soon as the frequency is no longer busy.

BEEP

Keypad Beep

When this function is enabled, every time a button is pressed, you will hear a beep tone.

CTCSS

Continuous Tone-Coded Squelch System

As DCS codes, the CTCSS codes can be added to the channels for creating new private channels.
Note: there are 50 groups of CTCSS tones. In channel mode, the CTCSS tones cannot be changed.

T-CTCS - Transmitting CTCS

R-CTCS - Receiving CTCS

DCS

Digital Code Squelch

 

DCS codes are similar to access codes and can be added to channels, so as to create a sort of personal channel. They enable the radio to communicate with the users that are tuned on the same channel and have set the same DCS code.

Note: the groups of DCS codes are 208. DCS codes cannot be changed in channel mode.

T-DCS - Transmitting DCS

R-DCS - Receiving DCS

DEL-CH

Delete a Memory Channel

You can delete a channel on the radio.

DTMFST

DTMF-Side Tone ofTransmit code

Determines when DTMF Side Tones can be heard from the transceiver speaker. You can choose amongst four options:
• Off: No DTMF Side Tones are heard.
• DT-ST: Side Tones are heard only from manually keyed DTMF codes.
• ANI-ST: Side Tones are heard only from automatically keyed DTMF codes.
• DT+ANI: All DTMF Side Tones are heard.

LED

WT-LED Display Backlight Color, Standby

RX-LED - Display Backlight Color- Receive

 

TX-LED - Display Backlight Color- Transmit

For UV-5R/GT-3TP and some other series:

OFF [0]

BLUE [1]

ORANGE [2]

PURPLE [3]

MDF-A

Channel A Display Mode

This function is used to set the display mode of channel A.
Display modes:
• CH [0]: Displays the channel number
• NAME [1]: Display the channel name
• FREQ [2]: Display programmed Frequency
Note: Channel name mode must be set by the programming software. In UV-5R there's up to three numbers or characters can be edited.

MDF-B

Channel B Display Mode

This function is used to set the display mode of channel B.
Display modes:
• CH [0]: Displays the channel number
• NAME [1]: Display the channel name
• FREQ [2]: Display programmed Frequency
Note: Channel name mode must be set by the programming software. In UV-5R there's up to three numbers or characters can be edited.

MEM-CH

Store a Memory Channel

This menu is used to either create new or modify existing channels so that they can be accessed from MR/Channel Mode.

MR Mode

Channel Mode

The use of Channel (MR) mode is dependent on actually having programmed in some channels to use.
Once you have channels programmed and ready, you can use the ▲/▼ keys or the encoder to navigate between channels.
◎ In MR mode, the channel number will be displayed on the right. Among them, GMRS communication (CH1-CH30) allows transmission and reception. Channels other than CH01-CH30 can only be scanned and received, and transmission is prohibited.

NOAA

Weather Receiver /Scan

Your radio can tune in to broadcasts by the United States National Oceanic and Atmospheric Administration (NOAA) Weather Radio and Environment Canada Weather Radio.

Your radio has an NOAA weather receiver function, to enable the user to receive weather reports from designated NOAA stations.

OFFSET

Frequency Offset

You can set the deviation between TX and RX. The frequency offset of this radio is 00.000-99.998MHz.

PONMSG

Power On Message

• FULL [0]: Performs an LCD screen test at power-on
• MSG [1]: Displays a 2-line power-on message
Controls the behavior of the display when the transceiver is turned on.

PTT-ID

When to send the PTT-ID

• OFF [0]: No ID is sent
• BOT [1]: The selected S-CODE is sent at the beginning
• EOT [2]: The selected S-CODE is sent at the beginning and ending
• PTT-ID Codes are sent during either the beginning or end of a transmission.

PTT-LT

Signal Code Sending Delay

PTT-ID Delay (milliseconds), 0-50ms.

RESET

Restore Defaults

VFO| ALL. Resets the radio to factory defaults, with some exceptions.

ROGER

Roger Beep

OFF|ON. Sends an end-of-transmission tone to indicate to other stations that the transmission has ended.

RP-STE

Squelch Tail Elimination

OFF|1 - 10. This function is used to eliminate squelch tail noise when communicating through a repeater.

RPT-RL

Delay the squelch tail of the repeater

OFF|1 - 10. Delay the Tail Tone of Repeater(X100 milliseconds)

SAVE

Battery Save

Power Save

 

Battery Save:

Selects the radio of sleep cycles to wake up cycles (1:1, 2:1, 3:1, 4:1). The higher the number, the longer battery would last. The higher number increases the RX sleep cycle, but you may miss the first few syllables before the RX opens.

Power Save:

The power save feature enables a reduction in the consumption of the battery when the radio is on standby.
You have 5 selections available: Off/ Mode 1/ Mode 2/ Mode 3/ Mode 4.

For example Mode 1= 1s’ working and 1s’ battery saving. Mode 2= 1s’ working and 2s’ battery is saving.
NOTE: The higher the number the longer the battery lasts. The higher number increases the RX sleep cycle, but you may miss the first few syllables before the RX opens.

S-CODE

Signal Code

Selects 1 of 15 DTMF codes. The DTMF codes are programmed with software, in UV-5R they're up to 5 digits each.

SC-REV

Scanner Resume Method

• To [0]: Time Operation-Scanning. Will resume after a fixed time has passed.
• CO [1]: Carrier Operation-Scanning. Will resume after the signal disappears.
• SE [2]: Search Operation-Scanning. Will not resume.

SFT-D

Frequency Shift

Enables access of repeaters in VFO/ Frequency mode.
• OFF [0]: TX = RX (simplex)
• + [1]: TX will be shifted higher in frequency than RX
• -[2]: TX will be shifted lower in frequency than RX

SQL

Squelch Level

Squelch silences the receiver when there's no signal. If the squelch is set to the highest level, the radio will receive the strongest signals only. Usually, the squelch can be adjusted to 10 different levels:

• Level 0: opened squelch. With this setting, UV-5X will detect all signals, also the weakest ones, but will also receive the background noise or undesired signals.

• Levels 1- 9: level 1 (lowest squelch level), level 9 (highest squelch level).

STE

Squelch Tail Elimination

OFF|ON. This function is used to eliminate squelch tail noise between Baofeng handhelds that are communicating directly (no repeater).
The reception of a 55 Hz or 134.4 Hz tone burst mutes the audio long enough to prevent hearing any squelch tail noise.

STEP

Frequency Step

Selects the amount of frequency changed in Frequency mode when scanning or pressing the ▲ or ▼ button. Note: in channel mode, this function cannot be modified. 

TDR

Dual Watch, Dual Reception

When this function is activated, you can receive the frequency of channel A and channel B at the same time.
If a signal is detected, the▼/▲ pointer will blink on the corresponding channel or frequency.

Note: In Dual Watch operation mode, you can c0hange the parameter of AB channel or frequency freely.

TDR-AB

Transmit Selection while in Dual Watch Mode

When enabled, priority is returned to the selected display once the signal in the other display disappears.

TOT

Time-Out-Timer

The TOT function is used to prevent a too long transmission and limits the tx time: TOT temporarily stops the transmission if the radio has been used beyond the max pre-set time (for example 15s, 30s, 45s, etc).
Note: If this option is set to OFF, press and hold the PTT key to keep transmission.

TXP

Transmit Power

Selects between HIGH and LOW transmitter power when in VFO/Frequency mode. Use the minimum transmitter

the power necessary to carry out the desired communications.

VFO Mode

Frequency Mode

In Frequency (VFO) mode you can navigate up and down the band by using the ▲/▼ keys. Each press will increment or decrement your frequency according to the frequency step you've set your transceiver to.

You can also input frequencies directly on your numeric keypad with kilohertz accuracy.

VOX

Voice Level

This function allows hands-free conversations: just speak in the direction of the microphone and the communication will be automatically activated.

You can choose amongst 11 levels: Off, 1-9. 1 is the highest level, 10 is the lowest one. If this option is set to Off, the VOX function is turned off.

Note: the higher is the level, the higher is the microphone sensitivity. The VOX function cannot be modified in SCAN and FM radio mode.

VOICE

Voice prompts function

With this function, you activate a voice that informs you about any operation/ selection you are doing.

WN

Wide/Narrow bandwidth

This function is used to set the working bandwidth of the radio.
You can choose between wide or narrow bandwidth.

Note: In channel mode, this function cannot be modified.

Excellent information. I have had hand held. Baofeng is so inexpensive and worth every penny. Works well and durable. Best thing for a Nub like me.

Benoit

Really like this. I was wondering what all the buttons, etc. mean.

I wish it was in a PDF document or something that was easily downloadable.
