      Couple questions:1. When the transmitter goes out of range or loses power, how does the receiver react?2. What does the VT pin do?3. Can I use one transmitter to talk to several receivers (one at a time) by using an Arduino to change the coding bits on the transmitter to match different receivers?4. Why doesn't the transmitter send when D1-D4 are all low? Also, how does the receiver react to this condition?5. How often does the transmitter update the receiver?

      If you are looking for a money pit, then you just found one. this will not work to transmit any data signals (no wireless data transport). you will not be able to use this device to transmit serial data. the fastest signal it can transmit is a 2Hz (while not compromising signal quality) yes a two Hertz signal (that pretty jokes right?) the only thing this works for is a remote detonator, or wireless digital switch. It would have been nice if someone told me this before i spent the money. you people really need to be more honest with your advertising. karma is going to have it's way with you yet...........PS: I am an electronics engineering technologist.

      @123Fake - I want to thank you for that honest feedback. It is utterly frustrating to buy "28-mile" RF radios only to find out it takes being in outer space to even get 3-miles. The only REAL specs have to be found by user reviews such as yours. Thanks again.

      Hi There,Does this kit support point to multipoint commuication. In other words, can I use one transmitter and make as a master transmitter to transmit to many receivers ??

      Hi Dear Customer, it is designed for point to point transfer. we only test the point to point transfer and we don't test the point to mulitipoint transfer. thanks. Bill

      Hi Dear Customer, Sorry for the previous reply and just confirm with design and the point to multipoint mode works well. thanks. Bill.

      Hello everyone.My name is Ramon and I am new, I would like to know if this module can be extended with other modules.For example. Instead of 4 channels, pass to hold 8, 12, etc.Thank you and best regards to all.

      I purchased this product because I want to use it for remote control (ON/OFF) settings. However, I already have a 433mHz transmitter/receiver (see here: https://www.amazon.com/433Mhz-Transmitter-Module-Receiver-Arduino/dp/B00G86L87E ). So how do I incorporate my existing 433 Mhz transmitter/receiver with this? What is the layout supposed to look like on the breadboard?

      Hi Dear Customer, we suggest use them separately. please refer our wiki (see here: http://wiki.seeed.cc/2KM_Long_Range_RF_link_kits_w_encoder_and_decoder/) about how to use the 2km kit. thanks. Bill

      Hello,

      Can you use multiple of these in the same area? I mean, can you adjust the carrier frequency to transmite information from different sources to different receivers. Thank you.

      Hi Dear Customer, if we use in the same area at same time, they will interference each other. thanks. Bill

      What exactly do I have to do to get this to work. I just want to supply voltage to a light when I activate the transmitter. What terminals do I solder and what pins do I use on the transmitter and on the receiver. Thanks

      Does RF Transmitter and Receiver able to transmit data (eg.hello) in open space upto 2km.

      if more than one RF transmiter transmit the data ,does one rf receiver able receiver the data of more than two transmitter at a time

      <p>Hi FAHIM, this couple of wireless module is not able to transmit character data, it only used for transmitting HIHG/LOW signal. You could have a look at RFbee or XBee Pro Chip Antenna - S1.</p>

      you can encode on single channel with low bitrate ASK (amplitude shift keying) using arduino or other MCU on both ends.

      It works great! It does take awhile to figure out (because they have zero documentation or anything in clean English) but once you do, they are great simple little devices. I use them for a home security notification system. If the led in my car turns

      I assume that if the output is driven by a UART and the receiver inputs it into a UART that serial communication will occur. What is a good speed to use?

      300 or 600 baud does wonders

      can multiple transmitters and receivers be used simultaneously in the same area (room)?

      <p>Basically is OK. But you need to keep them maintain at least 1m distance.</p>
