Figure 6-1: Typical PA A/D Values for One-PA Station (FM)
Note: Data shown for transmitter operating near 25 deg C ambient. The PA will draw higher
currents at higher ambient temperatures.
The following illustration (See Figure 6-3) shows typical PA A/D readings for a 2-PA
configuration (PT 1054) set at 75 Watts by subchannel.
