RF module 433hz

[afif]

when i build the simple circuit with encoder and decoder, my desired circuit is when i press the button it will light on the LED wirelessly......but the problem is sometimes when i press the button i manage to light on LED, but sometime when i press the button it really hard to get my desired output which is LED(on)....is there any possibility that RF module is broken??? or the circuit got something wrong??? please tell me any suggestion .........together with this im also attach the circuit

hi, better u switch the encoder ic from HT12E to HT12A...that is just enought to achieve ur objective....HT12A much more simpler than HT12E....i did some RF project last time...yes, it need some fine tuning..!
