Hi everyone,

I need urgent help, pls.

I have searched for the topic but couldn't find any satisfactory answers. Or maybe did not know where to look !..

Shortly, my problem is:

I have been using standart 433 MHz RF Receiver-Transmitter kit to transmit and receive some data such as heat, in short range (max. 20 Metres). And it is very simple to use.

But now I need to transfer and receive data upto 600 metres. But I do not know which kit to use ? (it should be as simple as the 433 mhz standart receiver)...

Thanks all in advance....
 

The data transmission between Receiver and the Transmitter is 433.92 MHz. I use a predefined library (rf.jal) to control the transmitter and the receiver so I do not know the baud rate between the pIC and the rf module.

But, in the new system that I want to make; I only need to send and receive one character; for example sending only "A" letter...
