Retevis Ailunce HS3 Software Defined HF VHF UHF Amateur Ham Radio

Retevis HS3 is an ultra-portable and all-band (100kHz to 2GHz) / all-mode (FT8, USB, LSB, CW, AM, FM, RTTY, DMR (optional) and WFM (receive only), etc.) SDR radio. With its dual VFO modes, it supports split-frequency operation, intermediate frequency offset adjustment, fine tuning, noise suppression, AGC speed selections, RF gain and squelch controls, integral pre-attenuator processing, integrated AM/FM broadcast receivers, automatic sleep and transmit-time-out timers, CAT and configuration cloning capabilities; the HS3 is truly a next generation field and QRP solution.

The HS3 leverages an externally attached modular 5AH battery-carrier designed to bean ideal complement for fully self-contained field radio deployments. This is especially true when the modular battery carrier is augmented with dual battery backup and the radio's native ultra-low power consumption architecture to significantly extend battery-powered operation times. To serve the varied interest of modern amateur radio operators, the Retevis HS3 also offers a standardized external 9VDC-18VDC power input (with reverse connection protection), allowing it to be equally at home in fixed-station and vehicle/mobile deployment scenarios.

To provide an optimized operational experience in a multitude of environments, the visual interface of the HS3 is designed around a high-resolution LCD display, with adjustable backlight brightness. This, combined with the user-selectable brightness level of the keypad, allows for clear and easy readability, even under the glare of mid-day outdoor conditions.

Designed as a modern multi-function SDR platform, the Retevis HS3 supports the QRadioBLE mobile app (amongst others), allowing for wireless control of the radio via Bluetooth and transforming operation and control into a convenient and fast app-based experience that very effectively eliminates problems related to wired common-mode interference. When direct wired connections are desired, the integrated internal sound card and serial control interface can still be accessed via a single USB cable, allowing for the support of a wide range of standard amateur radio software on a wide array of host computing platforms.

The HS3 has many advanced features typically available only in large base-station radios; dual VFO mode, split frequency operation, intermediate frequency offset adjustment, receiving frequency fine-tuning, intermediate frequency noise suppression, AGC speed selection, RF gain adjustment, squelch control, pre-attenuator, AM/FM broadcast reception, built-in CW automatic keying, automatic key point ratio adjustment, built-in CTCSS analog subtone, automatic sleep function and transmission timeout function (TOT) timers; computer-aided control functions, and data cloning options, amongst many other features, reinforce this concept.
