You can set the default output power in the Makefile of your
application, with a line like this:

PFLAGS += -DCC2420_DEF_RFPOWER=7

If you do not define CC2420_DEF_RFPOWER, the default is 3, I think: the
lowest TX power setting defined in the datasheet. Look in the CC2420
driver for details (just search for CC2420_DEF_RFPOWER in the TinyOS
source tree to find the right spot).
