Full frequency coverage

FM radio: Supports the global frequency band of 87.5-108MHz (with a step of 0.01MHz), and can store 32 preset channels (including 10 sets of NOAA weather stations).

AM medium wave broadcasting (only supported by some firmware versions): covering 520-1710kHz, requires external AM antenna accessories (purchased separately).

Intelligent signal enhancement

FM mode: Built in DSP digital noise reduction chip, supports RDS broadcast information display (radio station name/program type), automatically switches to mono to improve clarity when the signal is weak.

AM mode: using secondary frequency conversion superheterodyne technology to suppress nighttime ionospheric reflection interference, with a signal-to-noise ratio of ≥ 45dB.

Function FM parameters AM parameters (if supported)

Sensitivity ≤ 2 μ V (S/N=30dB) ≤ 5mV/m (S/N=20dB)

Store 32 sets of channels (editable by name, such as "BBC Radio 1") and 16 sets

Stereo separation ≥ 40dB (strong signal area) is not supported

Compliance certification EN 303 345 V2.1.1 (FM emission limits) FCC Part 15B (AM reception)

Operation process

Target channel locking: manually tune to the frequency point to be decoded (such as 446.00625MHz)

Quick key trigger: Long press SCAN + PTT for 3 seconds to start spectrum analysis

Automatic matching: The device compares the built-in 210 sets of DCS code tables with 50 sets of CTCSS frequency libraries

Result output: The screen displays the cracked sub tone code type and numerical value (such as DCS 023)

Parameter synchronization: Select "Apply" to write to the device with one click and immediately join the target channel

Real time weather warning

Equipped with 10 sets of NOAA official weather channels (162.400-162.550MHz), it automatically receives emergency weather alerts such as storms, floods, hurricanes, and wildfires issued by the National Oceanic and Atmospheric Administration of the United States. The warning information is pushed in a dual form of voice broadcast and on-screen text prompts.

Intelligent alarm triggered

Supports silent monitoring mode (continuous monitoring of weather signals in the background). When a local disaster alarm with SAME encoding (Specific Area Message Encoding) is detected, it immediately triggers an 85dB high-frequency alarm sound and automatically lights up the screen (at night or in low light conditions) to ensure that users respond in a timely manner.

Channel priority management

One main weather channel and nine backup channels can be set up, and the device automatically switches to the best receiving frequency point based on signal strength, paired with a weather warning exclusive mode (temporarily blocking regular calls) to avoid interference with key warning information.

Outdoor safety: Be aware of extreme weather conditions in advance when climbing or camping to avoid the risks of lightning strikes and flash floods

Disaster response: Real time tracking of storm paths during hurricane season to buy time for emergency evacuation of households/businesses

Commercial application: Logistics fleets adjust transportation routes through weather warnings to reduce cargo losses
