If you are referring to RF transmitter and receiver modules (?), then I have used both the Abacom (www.abacom-tech.com) and the Linx (www.linxtechnologies.com) RX and TX modules with PIC chips in the past, both for OOK and serial data transmission.

I am trying to develop a RF alarm for my car - that could transmit a signal to me when the alarm is activated. Thank you. Regards, S.
