Radtel RT910 Spectrum Analyzer AM FM Ham Radio 4559Mhz TXRX Walkie Talkie With 960 Channels AMFM Air Band Type C

Radtel RT-910 5w 6 Meter Multi band Walkie Talkie with 50-59Mhz RX 960 Channels AM/FM Two Way Radio Frequency range: 45-59Mhz FM TX/RX 65-108Mhz FM RX 108-136Mhz AM RX 136-260Mhz TX/RX 260-299Mhz RX only 300-520Mhz TX/RX List of sample output power: Features: SQL Squelch Squelch controls whether the radio receiver remains open or muted when no signal is detected. Setting squelch to 0 turns it off completely, allowing all background noise in — this may cause interference. Higher squelch levels reduce sensitivity but block unwanted weak signals. It's best to set this to a middle value to balance sensitivity and noise rejection. STEP Frequency Step This setting determines how much the frequency increases or decreases when using the UP/DOWN keys in VFO mode or during scanning. Available step values include: 2.5K, 5.0K, 6.25K, 10.0K, 12.5K, 20.0K, 25.0K, and 50.0K. Choose a step size that matches your local channel spacing requirements. TXP Transmit Power Controls how much power the radio uses to transmit. HIGH: Maximum power output, longer transmission range, higher battery usage MIDDLE: Balanced range and battery usage LOW: Saves battery life, shorter transmission range SAVE Power Save Mode Enables or disables power-saving features by adjusting the ratio of sleep and awake cycles during standby. OFF: Power saving is disabled 1 Normal Mode 2 er Mode 3 Deep Mode The higher the mode, the longer the battery lasts. However, you might miss the first few syllables of a received message because the receiver is sleeping. VOX Voice Operated Transmit When enabled, this function allows voice-activated transmission without pressing the PTT Push-to-Talk button. OFF: VOX disabled Levels 1 to 9: Enable VOX, with 1 being the most sensitive and 9 the least sensitive Useful for hands-free operation, but may trigger accidentally in noisy environments if sensitivity is set too high. W/N Wide/Narrow Bandwidth s the transmission bandwidth: WIDE: 25 kHz – better audio quality, but uses spectrum NARROW: 12.5 kHz – efficient, suitable for crowded radio environments or when regulations require it Backlight ON / Auto Off When set to ON, the display backlight stays on continuously. When set to OFF, the backlight turns off automatically after a period of inactivity to save battery. TDR Dual Standby oON: Enables dual standby mode. The radio monitors two frequencies/channels alternately and receives on whichever becomes active first. oOFF: Disables dual standby. The radio will only monitor one frequency/channel at a time. Beep Keypad Tone oON: Enables a confirmation tone each time a button is pressed. oOFF: Disables all keypad tones for silent operation. TOT Time-Out Timer oWhen enabled, this feature limits the maximum duration of a single transmission to prevent long, accidental transmissions. oHelps conserve battery and reduces the risk of interference due to a stuck PTT Push-to-Talk button. oOFF: No time limit; continuous transmission is allowed. Channel Add CH Memory Programming Used to save frequencies as channels Channel 0 to 256 so they can be accessed in MR Memory Recall mode. If "CH-" appears on the sn, the channel is already programmed and cannot be overwritten without deleting it first. Channel Delete Allows removal of stored channels. Note: If the channel number does not start with "CH", it means the channel is empty and cannot be deleted. CTCSS RX – Receive Tone oOFF: No CTCSS tone is used during receive. oIf enabled, the radio will only open squelch when the incoming signal contains the specified CTCSS tone. You can choose from standard tones or manually input a custom tone using the keypad. DCS RX – Receive Digital Code oOFF: No DCS code is used during receive. oIf enabled, the radio will only open squelch when the signal includes the ed DCS digital code. You can a standard code or enter a custom one. CTCSS TX – Transmit Tone oOFF: No CTCSS tone is transmitted. oIf enabled, the radio transmits the ed CTCSS tone along with your voice signal. Used to match repeater or group tone settings. Custom tones can be entered via the keypad. oT-DCS Transmit DCS Code OFF: No DCS code is transmitted. If enabled, the radio will transmit the ed standard DCS code e.g., D023N to D754I. You can choose from preset values or enter a custom one via keypad. VOICEPRI Voice Privacy / Subtone Encryption OFF: No encryption is applied. Encryption 1/2/3: Enables subtone encryption. When turned on, other radios using the same frequency and CTCSS/DCS code will not be able to hear your transmission, unless they also have the same encryption level. CH-NAME Channel Naming Allows you to assign a custom name to each saved channel. Use the # key to switch input methods e.g., letters, numbers, symbols. ROGER End-of-Transmission Tone OFF: No tone is sent when a transmission ends. BEEP: A simple beep tone is played at the end of each transmission to let others know you`re done talking. TONE1200: Sends a frog-like tone at the end of each transmission — often used for fun or attention. VOICE Voice Prompts OFF: No voice feedback for key presses or actions. ON: Voice prompts are enabled, providing audible confirmation of key presses and settings changes. LANGE Voice Prompt Lange Choose the lange for the voice prompts: ENGLISH CHINESE BCL Busy Channel Lockout OFF: You can transmit even if the channel is in use. ON: The PTT Push-to-Talk button is disabled if the channel is already occupied, preventing accidental interference with ongoing conversations. SC-REV Scan Resume Mode This setting determines how the radio behaves after detecting a signal during scanning: TO Time Operation: Stops on a signal for ~5 seconds, then resumes scanning even if the signal continues. CO Carrier Operation: Stops on the signal and only resumes scanning when the signal disappears. SE Search Operation: Stops scanning completely and remains on the active frequency after a signal is detected. PF2 Short Press Function Key Assignment Allows you to assign a custom shortcut to the PF2 button short press. Available functions: SOS, LAMP Flashlight, RADIO FM, TXPOWER, SCAN, SEARCH, NOAA. Choose the one that best suits your usage. PF2 Long Press Same as above, but this applies when you long press the PF2 key. You can assign a different function than the short press if needed. PF3 Short Press Function Key Assignment Assigns a shortcut to the PF3 button short press. Functions include: SOS, LAMP, RADIO, TXPOWER, SCAN, SEARCH, NOAA. Customize this key based on your usage needs. OFFSET Transmit/Receive Frequency Offset Specifies the frequency difference between the transmit TX and receive RX frequencies. Used primarily for repeater operation, where TX and RX frequencies are not the same. Example: Set an offset of 0.6000 MHz for standard VHF repeaters. SFT-D Direction for Repeater Use Controls the repeater direction when an OFFSET is configured: OFF: No frequency — simplex mode + Plus : TX = RX frequency + offset – Minus : TX = RX frequency – offset Used to match repeater uplink/downlink spacing. POWER ON MSG Startup Display Message Sets what is displayed when the radio powers on: : Shows the brand or sn VOLTAGE: Displays current battery voltage at startup Shopping Note For color: Pictures are for reference only.
