need a simple RF receiver which runs on 433Mhz

I need to design a simple 433Mhz RF receiver

I saw this post

.../thread27030.html

The receiver is really simple, but it is not calibrated on 433 mhz
does anyone know if you can incorporate a SAW filter
if it's necessary adding a transistor
I have seen some schematics of the transmitter with SAW and are very simple,
but I didn't find anything about a very simple SAW receiver.

You need to post a better link than that! What is the full URL?

I designed a data logger on a prototype board for my aquarium
that communicates with the PC for data exchange
via a transceiver module 433 mhz.
Now, I wanted to make others,for me and my friends, with a pcb
and so I wanted to integrate into the PCB also tranceiver
Consider the range is 6 / 7 mt ,and I can not use
the inexpensive IR technology because I did not always an optically visible field
I'm looking for a cheaper alternative to commercial modules 433
