The Retevis Ailunce HA1UV is a dual-band two-way radio designed for both amateur and users who demand durability, clarity, and power. This rugged handheld offers a mix of advanced features including IP67 waterproofing, a Sub-PTT function, and NOAA weather alerts. Because it supports both VHF and UHF bands, it’s ideal for a wide range of applications including outdoor use, emergencies, and ham radio operations.
Built with simplicity and performance in mind, the HA1UV is well-suited for beginners and experienced operators alike. Its robust build and flexible feature set make it a practical choice for those who want more from a handheld radio.
Frequency Support and Transmission Modes
The HA1UV operates on dual bands: VHF (136–174 MHz) and UHF (400–480 MHz). This broad frequency coverage allows the radio to access common ham radio repeaters, simplex channels, and other communication systems. Because of its dual-band capabilities, users can monitor or transmit on two frequencies at once, enhancing situational awareness and flexibility.
The radio supports both analog and digital transmission modes, giving it compatibility with a wide range of systems. This hybrid capability is valuable for operators transitioning between analog FM and digital standards, or those operating in mixed-mode environments.
Power Output and Performance
With a maximum power output of 5 watts, the HA1UV provides strong and reliable transmissions across various terrain types. This power level gives it excellent range for a handheld, especially when paired with an upgraded antenna. It also allows users to reduce power when operating near others, conserving battery and minimizing interference.
In terms of audio quality, the HA1UV delivers clear, crisp sound with strong reception even in busy RF environments. It uses a quality speaker and a sensitive receiver, which together improve communication in both quiet and noisy settings. As a result, voice clarity remains consistent across different use cases.
Waterproofing and Rugged Build
The radio is rated IP67 waterproof and dustproof, meaning it can survive being submerged in up to 1 meter of water for 30 minutes. Additionally, its completely sealed against dust, dirt, and sand.
The rugged reinforced casing is impact-resistant material, giving the radio shock protection from accidental drops. Therefore, it’s ideal for hiking, camping, emergency services, or any environment where conditions are unpredictable.
Battery Life and Charging
Equipped with a 2800mAh large capacity rechargeable lithium-ion battery, the HA1UV supports extended operating time. You will get up to 17 hours on a full charge depending on usage. The battery supports intelligent power management, so it can conserve energy when idle or transmitting on low power.
Charging is handled via a standard desktop cradle, making it convenient to dock at the end of the day. Some models also support USB charging, allowing for power on the go using portable battery banks or vehicle adapters.
Display and Interface
The HA1UV features a clear, backlit LCD display that shows essential information such as frequency, channel number, power level, battery status, and signal strength. The interface is easy to navigate, thanks to well-placed function keys and an intuitive menu system. Because of this, users can quickly adjust settings or switch between bands without diving through complicated menus.
The display also supports dual-watch mode, so users can monitor two channels at once. This is especially useful for operators managing both personal and emergency channels or keeping an ear on weather alerts while communicating.
Sub-PTT Function and Special Features
One standout feature of the HA1UV is its Sub-PTT (Push-To-Talk) capability. This allows users to transmit on two different channels using separate buttons, eliminating the need to switch back and forth between frequencies. As a result, multitasking becomes faster and communication more efficient, particularly in team or emergency operations.
The radio also includes NOAA weather alert support, providing real-time updates and warnings from weather broadcast services. This ensures users stay informed of storms, severe conditions, or sudden changes in the environment.
Advanced Features
Beyond its core specifications, the Retevis Ailunce HA1UV includes several advanced and practical features that enhance usability and reliability. These additions help the radio stand out in both emergency and recreational settings. Because of this, it offers greater control and adaptability in the field.
One standout feature is the customizable dual standby mode. This allows the radio to monitor two frequencies at the same time, ensuring you don’t miss important transmissions while engaged in other communications. This function is especially useful during group coordination or when monitoring a weather channel alongside your primary frequency.
Another helpful addition is the emergency alert function. With the press of a dedicated button, the radio can emit a loud alarm tone and send an alert signal to other radios on the same channel. Therefore, it provides a quick way to call for help or alert a team during urgent situations.
The programmable side keys give users fast access to commonly used features such as flashlight activation, scan mode, or switching power levels. Because the side buttons are customizable through software, operators can set up the radio to match their specific needs and preferences.
A built-in high-lumen flashlight adds utility in low-light situations. When you’re navigating a trail at night or searching a dark room during a power outage, the flashlight provides quick illumination without needing an extra device. Furthermore, it can serve as a visual beacon if you need to attract attention.
The HA1UV also supports channel naming, which allows users to label frequencies for easier identification. This simplifies navigation, especially when managing many active channels or sharing a radio with others who may not remember numeric assignments.
CTCSS/DCS
Finally, the radio includes CTCSS/DCS privacy codes, which reduce interference by allowing only radios using the same code to communicate. While not encryption, it helps keep channels quieter and more organized in busy areas. As a result, your communication experience remains clear and distraction-free.
