I bought your RF module to build my circuit and used PR16 as a reference.My question is:
1) Referred to the PR16's circuit,the transmitter also include with the transistor,but,when I bought it,it don't have. Why?? Do we need to put it by ourself? What is the function of that transistor?
2)Is the circuit for PR16 also contain noise?
3)By using the RF module produced by Cytron, can we eliminated that noise? How to it?
