Er, I believe that *four* watts is the maximum legal power that a
cellular radio may transmit. This is what is meant by ERP--Effective
Radiated Power.  The *three* watts refered to by most ads is the
*chasis* power of the device. However, after antenna gain this is
increased, but should not exceed 4 watts nominal ERP.

Sorry I didn't make that clear.
