I am currently looking for a simple RF transceiver for transmitting digital data. I want to build it myself, not just using a ready transceiver module. So I suppose a 27 MHz frequency and a range of about 100 meters would be sufficient.
Do you have any advice or suggest? Can you give me links to other similar projecs?
27 MHz is not a proper frequency band to transmit digital datas due to CB communication.In this band there may be very strong RF signals that will disturb the transmission.
Instead, I suggest you to use 433MHz ISM band for this purpose.Design may be more difficult but the transmission will be clearer.
