Simple help needed on RF TX RX circuit.

[AL3x]

Hi Guys and gals

This is my first post so firstly hello everyone!

Secondly i am looking for a simple RF TX RX decoder circuit which will give me the schematic and parts list?? its for a home pager project.

I have found this on the net: http://www.farnell.com/datasheets/65093.pdf#search='hirk433'

This would work for what i want but i cant get the schematic for the board so i cant alter the layout.

Any help will be greatly appreciated, i must warm everyone my electronics knowledge is limited but I'm hoping to learn alot more suring this project.

Thanks in advance

Alex

these guys make some fairly straighforward devices. kind of expensive though considering it's just a simple little tx/rx device. (ya hear that linx?)

Hey

Check this out:

You get modules from $17 for a RX/TX pair for 9600 and pretty good range to a more expensive 915MHz - 40,000bps - 90m Range FSK Modulation for about $30 bucks.

Bands range too - 2.5GHz and so on. I have used their cheapest little 315, 418, and 434MHz - 4800bps - 150m Range to download GPS plot info from my bike to the home computer. It works really cool - just like wireless RS232 cable HA

Thanks for the great help help guys.

The system im thinking of designiong would need to be encoded so it only works with the corresponding transmitter and reciever. So it doesnt interface with any surrounding products.

Any ideas on that front?

You can put unique serial # on each end and use basic software encoding - the key can be a hardware ID - real cheap, for about $2 per chip:

The DS1420 is a button that provides a 64-bit unique ID number, and is typically used to uniquely identify a person or a machine.
