transceiver circuit?

Hello. Can anyone help me with a design or a link to an rf short rang rc tranceiver circuit
that will output 4 bits and receive at least one back. I need at least 1 bit of feedback
from the device I am controlling remotely. I have done all the encoding and decoding.
I had a look at the rx5019/20. Would that do? Anyway, kick it around and I hope
to hear from someone soon. That would be hugely appreciated.
Regards,
lloyd88

I would use the modular 433MHz receivers and transmitters. I guessing that you do not need full-duplex links, meaning that you can listen for the acknowledgement after a command transmission is over?

transceiver circuit

Sorry, I should have said half duplex. I am using the 434`s now with the
ht12`s and it`s all good, but I need that feedback bit. What`s the best
way to go, do you think. I could duplicate for the sake of one bit, but
I know there is a better way. Cheers.

So are you asking if there is a 433 MHz transceiver instead of using two sets of TX/RX pairs?

I suppose that is what I am asking, yes. I have built a 4 bit one way system with
the ht12`s and if I swapped the transmitter and receivers with tranceivers,
I could just keep the 4 bit system and incorporate a 1 bit system around it.
Do you think?
