Detailed Description
General & Usability
- Wide Frequency Coverage: Operates on the 10-meter band (28.000–29.700 MHz) with an extended receive range of 24.500–30.105 MHz.
- Multi-Mode Operation: Supports AM, FM, SSB, and CW modes for versatile communication.
- High Power Output: Delivers up to 40W on FM/SSB/CW and 12W on AM.
- User-Friendly Interface: Features dual LCD displays for clear readout, a scan function, and a keyboard lock.
- Convenient Controls: Includes a programmable microphone with PTT/UP/DN switch and a beep voice prompt.
- DW Dual Watch Function: Allows monitoring of two frequencies simultaneously.
Advanced Technology & Optional Features
- AI-Based Noise Reduction (Optional): Enhances audio clarity by reducing background noise.
- VOX Function (Optional): Enables hands-free operation.
Technical Performance
- Precise Frequency Control: Utilizes a Phase-Locked-Loop (PLL) synthesizer with multiple step options (10Hz to 10KHz).
- Superior Receiver Sensitivity: Outstanding sensitivity for SSB (0.25µV) and AM/FM (1.0µV) ensuring weak signal reception.
- Excellent Selectivity: Provides sharp filtering (e.g., SSB: 6dB @ 2.1KHz / 60dB @ 3.3KHz) to minimize adjacent channel interference.
- Effective Noise Reduction: Includes a switchable RF-type Noise Blanker effective on all modes (AM/FM/SSB).
- Adjustable RF Gain: 45dB adjustable RF gain control for optimizing reception in varying signal conditions.
- Robust Audio: Delivers 3W of audio output into an 8-ohm speaker.
Durability & Power
- Built-in Protection: Features power supply voltage protection for reliable operation.
- Wide Operating Range: Stable performance across a wide temperature range (-30℃ to +50℃).
- Standard Connectivity: Equipped with a standard UHF (SO239) antenna connector.
