Maximum total power derating is 50%, i.e. 5W unmodulated carrier at 13.8V DC supply.
Transmitter low power option
For applications not requiring nominal TX power it is possible to select to reduce carrier power
by 50% (5W unmodulated carrier).
This reduces electrical power consumption during TX by approximately 40%. This option may
also be helpful in compromised installations to reduce RF feedback issues during TX.
