This FM radio receiver circuit is very simple to build and is powered by just a single 1.5V battery cell. Receiver consists of a regenerative rf stage, TR1, followed by a two of three-stage audio amplifier, TR2 to TR4. In some areas 3 stages of audio amplification may not be necessary...

If the meter needle vibrates will indicate the working of the circuit and the RF emission. A different approach could be, to connect the oscillator with the Antenna and Ground terminals of a CW receiver that could be tuned with the crystal frequency in order to determine the RF oscillations....
A simple AM receiver circuit based on the MK484 AM receiver IC from Rapid Electronics Ltd is shown here. MK4844 is a monolithic integrated circuit that has all the necessary sections of a AM receiver like RF amplifier, detector, AGC etc. The IC is available in TO92 package and requires ...
A section providing a pulse on CSR8635's PWER_E pin which wakes it up after the circuit has received power. The power section with anLT1308DC/DC converter which boost the battery voltage to 5V at max 1A. The power section is disabled when CSR8635 goes to shutdown on low battery (< ...
Please open the case and found the frequency saw on circuit board, it's surface will be marked with 433.92 or others. Just send this info to us if you are not sure of it. 2. How to pay? We accept T/T , west union, paypal , L/c. ...
This article shows you how to build a very simple FM transmitter from thirteen components, a Printed Circuit Board (PCB) and a 9v battery. This project was designed to be mounted on a PCB, however you don’t have to. You could construct the project on V
please note when power on, the lamp will be in the status of "ON" and the fan will be at "Hi" Speed. If you need other status when the power on, pls let us know when you placing order.An RF transmitter is ONLY able to remote control ONE ceiling fan...
The receiver uses 433Mhz, and has four relays inside the unit. ~ other relays could be added if needed. I am using separating them so that battery 1 provides power to relay 1. After receiving the first signal, RF1, Relay 1 then powers any consecutive relays/circuits. ...
