Robert,

Take a look at our site. http://www.orbitcoms.com/rf_modules.htm
The TRX2905 FSK, UHF transceiver module will do the trick

Up to 115k Baud.
Typical 300m range
USD$26.30 (1 up)

We will also be publishing details of a PIC based controller for this module
in the next 1-2 weeks that integrates the TRX2905 with a PIC16F876 and
provide all over-air firmware, Analog inputs, digital IO and Serial comms.

Regards

David Huisman
