| Step | Condition | Adjustment | Procedure |
|---|---|---|---|
| 1 | Band C, Channel 19 Mode: USB TX No modulation Mic Gain: Max. PA/CB: CB | VR10 | Disconnect the PCB-834 from Check Point of Main PCB and connect DC Ammeter to TP8 +, TP6 -. Adjust for 50mA on DC Ammeter. |
| 2 | Same as STEP 1 | VR9 | Connect AS Ammeter to TP8 +, TP7 -. Adjust to obtain the current 80mA. |
| 3 | Same as STEP 1 | L42 | Connect PCB-834 to Check Point of main PCB. Connect RF Power Meter, RF VTVM and Oscilloscope to Dummy Load. Set VR8 Max. Turn core of L42 ClockWise to maximum at the bottom. |
| 4 | Same as STEP 1 | L41 L43 L49 | Adjust coils for maximum indication. While then, keep output voltage under 25V by adjusting LF SSG |
| 5 | Band E, Channel 40 Mode: USB TX No modulation Mic Gain: Max. PA/CB: CB | L42 | Set E-band Ch. 40, adjust for maximum reading and then set A-band Ch. 1 and adjust for minimum difference from Band E Ch. 40. |
| 6 | Band E, Channel 19 Mode: USB TX No modulation Mic Gain: Max. PA/CB: CB | L30 | Adjust L30 to obtain the maximum indication on the RF VTVM. |
| 7 | Same as STEP 6 | VR8 | Adjust VR3 to obtain RF output of 32.4V on RF VTVM. |
| 8 | Same as STEP 1 | VR5 | Adjust VR5 to obtain the minimum carrier leakage between USB and LSB. |
| 9 | Band E, Channel 19 Mode: AM TX No modulation Mic Gain: Max. PA/CB: CB | VR11 | Adjust VR11 to obtain RF carrier power of 10Watt on RF Power Meter. |
| 10 | Band C, Channel 19 Mode: USB TX No modulation Mic Gain: Max. SW: S/RF | VR7 | Adjust for the needle of Bilt-in Meter to blank zone of TX Power meter. |
| 11 | Same as STEP 10 | VR12 | Adjust VR12 to obtain 90% (negative) modulation. |
| 12 | Band C, Channel 19 Mode: FM TX No modulation Mic Gain: Max. PA/CB: CB | VR4 | Connect Deviation Meter. Adjust for 3kHz Deviation on DeviationMeter. |
| 13 | Band C, Channel 19 Mode: USB TX No modulation Mic Gain: Max. SW: MOD | VR3 | Set AF SSG to 50% Modulation, then add 16dB. Adjust VR3 to 100% modulation indication on the Tranceiver meter. |
| 14 | Band C, Channel 19 Mode: AM TX No modulation Mic Gain: Max. | VR6 | Adjust Transmitter Frequency for 27.185MHz +/- 100Hz on Frequency Counter. |
