TX power level tuning

This tuning must be done in all three bands.
Note: TX Power tuning must be done with a peak power meter, e.g. Anritsu model
ML2408A with Anritsu Peak Power Sensor MA2442A and a suitable attenuator.
The use of power meter in GSM testers is likely to cause larger error than the use of a
dedicated power meter and might cause the phone to be non-compliant with GSM spec-
ifications.
Set power supply voltage Vcc=3.6V!
