Hmm, what exactly do you mean by "Carrier signals"?  Do you just want to
change the power, freq, and modulation?  Or is there other stuff?

iwconfig can change many of these settings, but not necessarily all of
them.  It can certainly change frequency/channel and TX power, but
setting the modulation is likely not possible via iwconfig.  It may be
possible to force a modulation by locking the card's bitrate to <=
11Mbit though, not sure about that.
