    Now I can return the favor.  A company called Linx Technologies:
www.linxtechnologies.com has a transmitter that operates just above 900MHz.
it has eight chanels that can be controlled by a PIC.  It takes in data
serially and can handle up to 50kps data rates.  The only external part
required is an antenna.  There is both a transmitter and a receiver.  They
cost about $28 dollars each.
