4.3.4.

Automatic Transmit Power

Control

The RF power detector (D2) detects

transmitted  feedback  then  sends
the readout to audio processor U8.
The  special  firmware  module
compares  the  transmitted  power

against the referred level stored on
current channel memory adjusting

the power control level generated

as reference by one DAC output on
the same processor (U8) then

amplified by U3 (MCP6241U)
controlling the gate current on Q1

and Q17.
