Hello everybody (;

I want to transmit (in one direction) RS232 from my pic16f887 through a rf transmitter to my pc.
I use the telecontrolli 433Mhz rr3 receiver and rt4 transmitter modules.

The problem is when I see a lot of garbage on the screen when I connect it.

My circuit is designed considering voltage shifting(max232) and maximum datarate(2khz), but I still get a lot of unwanted noise, even with pairity check.


I know that my transmitter and receiver are working properly. the only problem with them I can think of is that they are not meant to work with rs232 communication.

What can be the problem?

I prefer to use my rf module, as I don't want to go and buy a new one.
What can I do?


if not, does anyone know a good rf transmitter and receiver I can use?
