Working principle: triode, LC oscillating circuit, secondary amplifier
Frequency adjustment: screw the trimmer capacitor
Frequency stability: The frequency is basically stable, the antenna does not drift when Pressed by hand, and the frequency of the power supply voltage changes will change
Audio input mode: onboard electret microphone, audio input, volume adjustment
Memory function: restore the last frequency each time the power is turned on
Name: C type transmitter module
Function: high power transmission
Power supply voltage: 3-5V
Working current: 85mA (5V)
Frequency range: 85-115MHz
Launch distance (open): 300-800 meters
Pickup and radio sensitivity: within 30 square meters, the audible sensitivity of the second hand is continuously adjustable
Channel: Mono
Uses: monitoring, maternal and child monitoring, stage performance, speech intercom, communication
1. [Receiving method] Ordinary FM radios can be received, and mobile phones with FM functions are also available, but Internet radios whose software APP requires network traffic cannot be used.
2. [Frequency adjustment] The miniature adjustable capacitor on the circuit board can be adjusted with a small screwdriver
3. [Sensitivity] The microphone is placed in a quiet 30 square meter room, and the second hand of the quartz clock is clear and audible.
4. [Scope of application] High-sensitivity wireless microphone, wireless recording, wireless monitoring, remote recording, maternal and child care, patient care, etc. Due to the high sensitivity, it is not suitable for stage performances, and it is easy to produce whistling noise
5. [Working time] The working time of the module is determined by the battery capacity. Output impedance 50 ohms
