i bought two RF modules STT433 and STR433 modules and i tried to check it out...
i gave the power supply connections and shorted the antenna pins of the two modules and gave data input logic one at the transmitter ,
but i did not get the logic one at the receiver output, instead i am getting pulses at the output which is not having any time period
after that i used helical antennas at the antenna terminals and even after that i am not getting the required output.
can u please help me in the design of antennas for the STT433 STR433 modules and help me how to check the working of the modules....
thanks in the advance
please help me ....
yours sincerely,
