For radio enthusiasts who demand both power and performance, the Radioddity VB70-B 70W VHF Mobile Ham Radio stands out as a robust option tailored for serious amateur radio users. Designed for the 144-148MHz VHF frequency range, the VB70-B brings together exceptional transmitting power, advanced audio features, and modern connectivity options in a compact and rugged form factor. This review explores its core capabilities, practical use cases, build quality, and overall value.
High Power and Performance
The most striking feature of the Radioddity VB70-B is its impressive 70-watt output power, a significant boost over the common 50-watt models in the same class. This added power extends transmission range, improves signal strength in less-than-ideal environments, and ensures that communications are stable even under challenging atmospheric conditions. Whether used in rural, mountainous terrain or in emergency preparedness setups, the 70W output makes a noticeable difference in clarity and reliability.
Users can also toggle between high (70W), medium (25W), and low (5W) power settings depending on their operational needs. This flexibility ensures efficient battery or power supply use and prevents unnecessary interference with nearby frequencies when less power suffices.
VHF Focus with Air Band Support
The VB70-B is designed to operate exclusively within the VHF band (144-148MHz), making it ideal for local and regional amateur radio communications. While it does not support UHF, it compensates with added Air Band reception. This allows listeners to monitor aviation communications, an appealing feature for hobbyists, emergency volunteers, or those with an interest in air traffic monitoring. Though it is receive-only for Air Band, the feature adds versatility to an already strong package.
Bluetooth and Wireless PTT
One of the modern touches that sets this unit apart is its integrated Bluetooth functionality. This feature enables wireless audio accessories, such as headsets, to be paired with the radio for hands-free operation. It’s especially useful for mobile setups in vehicles, where ease of access and minimal distraction are crucial.
Complementing the Bluetooth feature is the inclusion of a wireless Push-To-Talk (PTT) module. This small, separate device can be mounted within easy reach in a vehicle or held in hand during base station use. It brings added freedom of movement and allows operators to communicate without having to stay glued to the main radio unit or its handheld mic.
Effective Noise Reduction
Audio clarity is often a concern with high-powered radios, especially in mobile environments where background noise can interfere. The VB70-B addresses this issue with a built-in noise reduction function. This digital noise suppression system helps filter out engine hum, wind, and static interference, providing a crisper and cleaner audio experience for both the transmitting and receiving ends of a conversation.
Even in urban areas with electrical noise or in mobile units moving through noisy environments, the noise reduction technology contributes to improved intelligibility, reducing the need to repeat messages or strain to hear incoming signals.
Channel Capacity and Organization
With 510 programmable memory channels, the VB70-B provides ample room for organizing repeaters, simplex frequencies, weather channels, and more. These channels can be grouped, named, and managed using programming software, making it easier to navigate your preferred frequencies without manually tuning during operation.
This extensive channel capacity is useful for both daily use and special event setups where multiple frequencies may need to be monitored or cycled through quickly. Whether used in public service events, emergency response, or regional nets, having room for hundreds of custom channels is a major advantage.
Build Quality and Usability
The VB70-B features a durable metal chassis and a well-ventilated design to support long-duty cycles without overheating. The front panel is user-friendly, with a bright LCD display that shows essential data such as frequency, power level, and channel name. The control knob and buttons are tactile and responsive, allowing for quick adjustments even while driving or operating in low-light conditions.
The included hand mic is comfortable to use and features programmable buttons for quick access to commonly used functions. The unit's compact form makes it easy to mount in various vehicle configurations or integrate into a home station setup with minimal space requirements.
Versatility and Use Cases
This radio is an ideal match for a wide range of users:
-
Mobile Operators: With its powerful 70W output, wireless PTT, and Bluetooth headset support, the VB70-B is well-suited for amateur radio operators who communicate while on the move.
-
Emergency Communications: Its high power, channel flexibility, and noise reduction features make it a solid option for volunteer emergency communications teams.
-
Aviation Enthusiasts: The Air Band reception adds an extra layer of utility for those interested in following aviation communications.
-
Radio Clubs and Events: The channel memory, clear audio, and robust build make it reliable for ham radio clubs organizing nets or field events.
Conclusion
The Radioddity VB70-B is a well-rounded, high-performance VHF mobile radio that offers more than just brute power. With modern touches like Bluetooth connectivity, wireless PTT support, and noise reduction, it caters to both traditional ham operators and tech-savvy users looking for added convenience and functionality. Its 70-watt output provides extended reach, while the channel memory and Air Band reception enhance overall utility. Whether mounted in a vehicle, installed at a base station, or used in an emergency setup, this radio delivers performance, durability, and advanced features in one compelling package.
