Exploring some wireless communication transmitter and receiver modules from eBay. They operate at 433.92 MHz RF frequency. Some tests, oscilloscope measurements, schematics and how do they work. Correction: dBm means decibel milliwatts, not decibel meters, but the abbreviation easily leads to confusions.
