3. Place the unit into transmit by grounding MIC KEY, P165A1-6.
4. Monitor the audio level out of COMM AUDIO/SIDETONE/INTERCOM OUT,
P165A1-9.
5. Adjust Nav frequency knobs for NLT 1.3VRMS and NMT 1.5VRMS.
5.2.2.4.3 Intercom
1. Go to INTC page
2. Input a 100mVrms, 1kHz tone into the INTERCOM MIC P165A1-B.
3. Monitor the audio level out of COMM AUDIO/SIDETONE/INTERCOM OUT,
P165A1-9.
4. Adjust Nav inc/dec knobs for NLT 7.07 Vrms
5.2.2.5 Glideslope Receiver Alignment
R25 fully CCW
5.2.2.5.1 Reference Crystal Oscillator
1.Monitor TP9 using a counter.
2.Adjust C66 so that the frequency is 20.950 MHz
5.2.2.5.2 VCO Adjustment
1.Channel the NAV receiver to 109.3 MHz(332 MHz GS channel, 331.970 GS LO
frequency).
2.Monitor the DC voltage at TP3.
3.Adjust C75 for 4.0
5.2.2.5.3 RF Front End Alignment
1.Channel the NAV receiver to 109.3 MHz(332 MHz GS channel, 331.970 GS LO
frequency).
2.Monitor TP6 with a DVM having 1 mV resolution.
3.Apply a 332 MHz RF input at -87 dBm.
4.Adjust L5, L6, and L13 to maximize the voltage at TP6. If necessary, increase
the RF input power so that TP6 voltage changes can be seen when adjusting L5,
L6, and L13. Reduce input power to -87 dBm for final adjustment.
5.2.2.5.4 RF AGC Adjustment
1.Channel the NAV receiver to 109.3 MHz (332 MHz GS channel, 331.970 GS LO
