3.3 100MW 50 OHM RF OUTPUT
This is the RF output and produces 100mW of power into a 50 ohm
resistive load. This is used to drive a dummy load or antenna or other
system that is designed with a 50 ohm input. This output should
always be terminated with 50 ohm when the transmitter is powered.
Operating the transmitter without a 50 ohm load will not cause
immediate damage, however, it will cause the internal amplifier to
operate at high temperature and thus reduce the long-term life of the
unit.
If the power is set to maximum with VR2 RF PWR ADJ turned fully
anticlockwise and the DRIVE POWER LED is dim or completely
extinguished, then antenna load is not 50 ohms. With a 50 ohm load
the DRIVE POWR LED will have normal brightness.
