Functional characteristics

1. Using digital pilot and ID code identity authentication technology, the same frequency band can be stacked 10 sets of machines at the same time

2. PLL frequency synthesis stabilization system is adopted to provide 200 channels

3. Adopt the latest high frequency filter to filter out the interference signal outside the band to the maximum extent

4. High frequency circuit design with double frequency conversion, with high sensitivity

5. Multiple noise control circuit, reject external interference receiving distance up to 250 meters.

6. Specially designed speech compression and expansion circuit, greatly improve the signal-to-noise ratio

7. Unique circuit design, large dynamic, wide frequency response, low noise
