| Step | Condition | Adjustment | Procedure |
|---|---|---|---|
| 1 | Mode: TX USB 27.185MHz S1 and S2 OFF | VR11 | Disconnect PC834. Connect DC Current Meter on TP9(+) and TP8(-). Adjust for 50mA. |
| 2 | Mode: TX USB 27.185MHz S1 and S2 OFF | VR9 | Disconnect PC834. Connect DC Current Meter on TP9(+) and TP8(-). Adjust for 4mA. |
| 3 | Mode: TX USB 27.185MHz S1 and S2 OFF | VR10 | Disconnect PC834. Connect DC Current Meter on TP9(+) and TP8(-). Adjust for 80mA. |
| 4 | Mode: TX USB 27.185MHz S1 and S2 ON Modulation: 2,4kHz and 500Hz | L46 | Set the core of L46 to the bottom, adjust VR12 to minimum. |
| 5 | Mode: TX USB 27.185MHz S1 and S2 ON Modulation: 2,4kHz and 500Hz | L45 L48 L49 | Adjust the cores to obtain max. deviation on RF VoltMeter. Repeat this operation with lower AF levelss on MIC input. |
| 6 | Mode: TX USB 27.185MHz S1 and S2 ON Modulation: 2,4kHz and 500Hz | L46 | Adjut to obtain max deviation on RF Voltmeter. Adjust to obtain a mimimum power difference between Ch.40 HIGH and Ch.1 LOW |
| 7 | Mode: TX AM 27.185MHz S1 ON Modulation: 1kHz | L37 | Adjust to obtain max deviation on S/RF Meter |
| 8 | Mode: TX AM 27.185MHz S1 ON Modulation: 1kHz | VR12 | Adjust to obtain 32,4 Volt on RF VoltMeter |
| 9 | Mode: TX USB 27.185MHz S1 and S2 OFF | VR7 | Adjust to obtain minimum difference between USB and LSB |
| 10 | Mode: TX AM 27.185MHz S2 OFF | VR13 | Adjust to obtain 10 Watt on RF Power meter |
| 11 | Mode: TX AM 27.185MHz S2 OFF | VR8 | Set Switch on S/RF. Adjust to set the S-meter between the Red and Green field |
| 12 | Mode: TX AM 27.185MHz S1 ON Modulation: 1kHz 30mV | VR14 | Adjust to obtain 90 % AM-Modulation on Oscilloscope. |
| 13 | Mode: TX FM 27.185MHz S1 ON Modulation: 1kHz 30mV | VR5 | Adjust to obtain +/- 2 kHz deviation on DeviationMeter. |
| 14 | Mode: TX AM 27.185MHz S1 ON | VR15 | Set switch on MOD, AF SignalGenerator to obtain 50% modulation. Adjust levels of AF Signal Generator to 16dB. Adjust VR15 to obtain 100% modulation on S-Meter. |
