The Radtel RT-910B is a multi-band handheld radio that combines power, flexibility, and modern programming options. It covers a wide frequency range, including the 6-meter band from 45 to 59 MHz for both transmit and receive, making it a rare choice for operators who need coverage beyond standard VHF and UHF ranges.
This handheld also supports FM and AM reception, allowing users to monitor commercial broadcast stations and air band frequencies. With Bluetooth app programmability, this radio lets users manage channels and settings wirelessly, providing a streamlined way to customize and control the device.
Features and Performance
The Radtel RT-910B provides a broad selection of features that cater to amateur radio operators, emergency communication teams, and hobbyists. It includes DSP-based spectrum noise reduction, which improves clarity by cutting background interference.
As a result, communication remains crisp even in noisy environments. Additionally, the radio supports up to 960 programmable memory channels, making it ideal for complex communication setups.
Bluetooth app programming allows for rapid configuration without connecting to a computer. You can create channel groups, clone settings to other units, and adjust features directly from your smartphone. This eliminates the need for manual entry and speeds up deployment, especially when setting up multiple radios.
The radio offers three selectable transmit power levels: High for maximum range, Middle for balanced use, and Low for conserving battery life. These levels help users adapt to varying conditions, such as nearby repeaters or distant contacts. A multi-level power save mode further extends battery performance by reducing activity during idle periods, though higher levels of power saving may slightly delay signal reception.
Advanced Frequency Coverage
The RT-910B supports more than just basic amateur bands. It covers 65 to 108 MHz for FM broadcast reception, 108 to 136 MHz for AM air band monitoring, 136 to 260 MHz for VHF transmission and reception, 260 to 299 MHz for receive-only signals, and 300 to 520 MHz for UHF operations. This wide range provides unmatched versatility in a compact device, making it useful for monitoring, scanning, and communication.
Operators can fine-tune frequency selection with adjustable scan step sizes. Available options range from 2.5 kHz to 50 kHz, which improves scanning efficiency and helps locate signals precisely. The adjustable squelch feature allows users to block unwanted noise while staying sensitive to weak signals. For practical operation, a mid-range squelch setting often strikes the best balance between sensitivity and noise suppression.
Operational Tools
The Radtel RT-910B includes a range of tools designed to make communication easier and more efficient. The VOX feature enables hands-free transmission by activating the microphone through voice detection. Adjustable sensitivity levels let you tailor VOX performance to match your environment. Dual-standby mode, also known as TDR, allows the radio to monitor two different channels alternately, ensuring you never miss an important message.
The radio includes a Time-Out Timer (TOT) that automatically ends a transmission after a set period, preventing accidental long transmissions and reducing network congestion. Users can also choose between wide bandwidth (25 kHz) and narrow bandwidth (12.5 kHz) operation depending on local regulations and signal congestion.
Additional conveniences include keypad tones, adjustable backlighting for low-light use, and shortcut keys for quick access to common functions. These features make the radio practical and user-friendly, even for operators who are new to multi-band handheld radios.
Bluetooth Programming
Bluetooth connectivity is one of the defining features of the RT-910B. Through a dedicated smartphone app, you can program frequencies, organize memory channels, and even copy configurations between radios. This wireless method greatly simplifies setup compared to traditional programming cables. Channel grouping helps keep related frequencies organized, which is especially useful for emergency services or events with multiple teams.
With 960 channels available, users can store local repeater frequencies, simplex channels, and specialized monitoring frequencies without running out of space. This extensive memory makes the radio suitable for both hobbyist use and professional fieldwork.
Technical Specifications
The Radtel RT-910B includes a strong 1800 mAh rechargeable battery with modern USB Type-C charging.
