Port Outputs the data signal to the DA Description number name DADATA CONVERTER (IC11, pin 17). The output voltage The voltage from the external power supply via from the 5 regulator circuit (IC5) is applied to the VDD ter- the W501 (OPC-465). The output voltage of (MAIN UNIT) the APC amplifier (IC15, pin 1) controls the bias voltage of The RF signals from the low-pass filter (VCO board) pass the power module (IC14) to reduce the output power via the through the high-pass filter (L69, C119) and attenuator APC controller (IC15, D531). The drive amplifier circuit amplifies the VCO oscillating sig- nal to a level needed at the power amplifier. When receiving strong 9, 8), and are then applied to the DA converter IC (IC4, pin signals, the detected voltage increases and the AGC voltage 13) to adjust modulation level.
