1. Broad Compatibility
   – Covers 240 CB (Class D) channels (26.065–27.855 MHz), meeting multi-regional needs. The optional frequency range for Poland (26.060–27.850 MHz) ensures compliance with local regulations.
2. High Sensitivity and Anti-Interference Capability
   – Receiver sensitivity ≤1.0 µV (for 10dB S+N/N), enabling clear reception in weak signal environments.
   – Adjacent channel rejection ≥60 dB (at 10 kHz) / >70 dB (at 20 kHz), minimizing interference in crowded frequency bands.
   – Dual intermediate frequency (IF) design (1st IF: 10.695 MHz, 2nd IF: 455 kHz) enhances signal filtering and ensures stable reception.
3. Stable and Efficient Transmitter Performance
   – Output power 4W (max 7W), compliant with CB Class D standards for balanced range and legality.
   – A3 (AM) modulation capability of 80–90%, delivering efficient signal transmission and clear voice quality.
   – Spurious radiation ≤-62 dB and frequency tolerance <0.002%, ensuring minimal interference and high stability.
4. Practical Design and Adaptability
   – 50Ω standard antenna impedance, compatible with mainstream antenna systems.
   – Supports 12–16V DC (positive/negative ground), adaptable to various vehicle power systems.
   – Compact and lightweight (124×38×190 mm, 1.2 kg).
5. User-Friendly Features
   – Adjustable squelch range 1.2 µV–1 mV, adaptable to varying noise environments.
   – Audio output 4.5W (max) with 450–2500Hz frequency response, ensuring clear voice reproduction.

**Summary**: This transceiver excels in frequency coverage, anti-interference, transmission stability, and portability. It is ideal for CB radio users requiring reliable communication (e.g., fleets, outdoor operations), particularly in cross-border or multi-regional scenarios.
