rf donr receive signal

[acheron]

i just bought PR16-Sending Data Using RF Module , but the Rx315 seem like cant receive any signal..how to check which module either TX or RX that broken? if we connect the rx or tx module in wrong polarity and then change it back to the right one, is the module already broken or no?

Most probably.... sudah mati . I don think this low cost RF wireless device come with polarity protection, need to be careful next time.
