*Full transmitter output power is available during battery revert.
NOTICE: The output power reference plane is the output connector of the power amplifier. The
loss of the transmitter output cable (PA output to back of base radio) 1% at 150 MHz. However,
the base radio software allows the transmitter output power to be set at 10% above rated value.
If more than 70 dB Intermodulation Attenuation is required at a site, an external circulator
should be added to the transmitter output.
