Changed Tx Pwr attenator range to 45dB

Browse Source 
This  is now  half way  between  the recent  change to  30dB when  the
formula was corrected  to voltage attenuation from power  and prior to
that.

Also corrected  formula for  the SoundOutput::attenuation  property to
use the correct voltage attenuation calculation.
