Review on HiLetgo Wireless 2 Channel Transmitter 100 600MW by Michael Moulton

My transmitter arrived with the main capacitor and microswitch module knocked off the surface mount board. Also no documentation or instructions of any kind and no website links. If you look at the manufacturer's website, there is no mention of this product. The only documentation I could find was for the BH1417 chip. It was easy enough to re-solder the capacitor and replace the dip switch with hard wires. After installation and operation, the transmitter works perfectly. Excellent separation and sound quality. Low hum from my backup source. The device is very stable regardless of the input voltage. The output power is 100 mW from my meter. My unit transmits about 600 feet with a 2 foot wire antenna in a ground floor room. Not bad for a cheap device.
