We used the receiver much more.  Beware that the default flags don't use
the barker code (because it's so cpu intensive), and that you'll have to
turn that on if you want to try to interoperate.

How are you injecting packets into the transmitter?  We had this set up
to use a pseudointerface to get packets to/from the kernel from the
802.11 code.  If you don't send it packets it won't send anything.
