List of sample output power:






Easily program your radio wirelessly via Bluetooth โ no cables required.
Compatible with iOS & Android devices
Use the official Radtel app to configure frequencies, channels, power settings, and more
Fast and flexible for both beginners and advanced users
Enhanced digital noise suppression ensures clear communication even in loud environments.
Filters out background noise in real time
Ideal for construction sites, events, industrial, or outdoor use
Improves voice clarity and reduces fatigue in long-term usage
Squelch determines whether the radio stays silent or emits static when no valid signal is detected.
Level 0: Squelch OFF โ all background noise passes through
Higher Levels: Block weak or unwanted signals
Recommended: Mid-range setting for optimal balance between reception and noise suppression
Defines the step size when tuning frequencies in VFO mode or scanning.
Available Values: 2.5K / 5.0K / 6.25K / 10.0K / 12.5K / 20.0K / 25.0K / 50.0K
Tip: Match with your regionโs standard frequency spacing
Select the desired transmission power level:
HIGH: Maximum range, faster battery drain
MIDDLE: Balanced between power and efficiency
LOW: Energy-saving, shorter range
Reduces battery consumption during standby by controlling the radio's sleep/awake ratio.

Allows hands-free operation by transmitting when sound is detected (no PTT button needed).
OFF: VOX disabled
Levels 1โ9: Enable VOX, with Level 1 being the most sensitive
โ ๏ธ Higher sensitivity may trigger transmission in noisy environments
Select the transmission bandwidth:
WIDE (25 kHz): Better audio quality
NARROW (12.5 kHz): Saves spectrum, ideal for crowded or regulated areas
Controls display lighting:
ON: Always-on backlight
OFF: Backlight turns off after inactivity to save battery
Monitor two channels/frequencies alternately.
ON: Dual standby enabled
OFF: Single-channel monitoring only
Enables audible feedback when pressing buttons.
ON: Key tones active
OFF: Silent keypad operation
Limits transmission duration to avoid long accidental transmissions.
OFF: No limit
ON: Transmission is limited to preset time
Save VFO frequencies to channel memory (CH0โCH256).
Channels marked โCH-โ are already programmed
Delete saved channels from memory.
Empty channels (no โCHโ) cannot be deleted
RX CTCSS: Radio unmutes only if incoming signal has matching tone
TX CTCSS: Transmits selected tone with voice
OFF: No tone used
Supports standard & custom tones
RX DCS: Only receives signals with matching DCS code
TX DCS: Transmits selected DCS code
OFF: Disabled
Choose from standard presets or enter custom codes
Encrypts your audio signal using sub-tone scrambling.
OFF: No encryption
Levels 1 / 2 / 3: Increasing levels of privacy
Prevents unauthorized listening on same frequency
Assign custom names to saved channels.
Use # key to switch input modes (letters/numbers/symbols)
Plays a tone at the end of each transmission.
OFF: No tone
BEEP: Standard confirmation tone
TONE1200: Playful โfrogโ tone
Audible feedback for settings and button presses.
ON: Prompts enabled
OFF: Prompts disabled
Choose the voice prompt language:
ENGLISH
CHINESE
Prevents transmitting if the channel is already in use.
ON: Blocks transmission on busy channel
Sets scan behavior when a signal is detected:
TO (Time Operation): Resume scan after 5 seconds
CO (Carrier Operation): Resume only after signal ends
SE (Search Operation): Stop scan and stay on signal
Assign custom features to short or long presses:
Options: SOS, LAMP (Flashlight), RADIO (FM), TXPOWER, SCAN, SEARCH, NOAA
PF2 and PF3 can be independently customized
Defines the frequency difference used with repeaters.
Example: 0.6000 MHz for VHF
Used with SFT-D to calculate final TX frequency
Sets direction for frequency shift:
OFF: Simplex operation
+: TX = RX + offset
โ: TX = RX โ offset
Choose whatโs displayed when powering on the device:
