Works great for RF remote sniffing
I got this to decode signal from an rf remote and then send it out for automation purposes. Receiver (no antennas attached) is not great but it worked when the remote was right up to it. Transmitter works great.

Added functionality for your Arduino projects.
This item required me to tune it in order for it to work. TX pin 12 on the nano and RX pin 11 on nano. I also couldn't get it to work unless I soldered on an antenna on each module.

receiver is trash, transmitter is good
both receivers are worthless, transmitter works great.

The transmitter generates RF, the receiver receives rubbish. Save your money, look elsewhere
The transmitter does work, checked it with a frequency counter and it's pretty close to 315 MHz. The receiver however, occasionally responded to the transmitter but mostly just output digital rubbish. I tried tuning it as others have and could sort of peak the signal but the digital rubbish never went away.BTW, no info on transmitter voltage required, mine had no RF output below 7 VDC so forget running it on 5 Volts.

Great product, just one "issue".
So far so good! They communicate pretty effectively at a decent distance. Only issue I had was with getting the right frequency for the receiver. It wasn't calibrated at the factory. To those that are struggling: hook the pair up to some Arduinos and have one constantly transmit a signal, on the receiving end, just continually scan for that signal and slowly turn the frequency knob until you pick it up. Best wishes! Stay creative.

Ok for experienced people but beginners look elsewhere
Got it to work but doesn't have clear documentation

The receiver does not work well
The transmitter seems to work fine, but the receiver really doesn't work at all. It is not clear why, but it always required some jiggling and fiddling for it ever to receive a simple test signal.

Does what it does
It takes the air and makes it 315mhz bits instead. It did this with modest efficacy.Clearly recycled parts which is good.Probably made with slave labor. :-(
