Review on Songhe FM Transmitter Pickup Module - Mini Wireless Microphone for FM Emission - Wireless Audio Transmitter MIC Core Board V4.0 by Aaron Kindler

Revainrating 3 out of 5

The fundamental frequency is half the specified operating frequency

When the FM receiver receives a signal from a 100MHz transmitter, the fundamental frequency of the transmitter is 50MHz. You hear the second harmonic in the FM receiver. The power level of a 100MHz signal is about 11dB below pitch. The power level of the fundamental frequency is about 10 mW.

Pros
  • Price
Cons
  • No automatic
