FM DEVIATION: Mode to FM MIKE GAIN to maximum. Inject audio signal of 1KHz 30mV (-18 dBm) at MIC jack. VR8 Adjust so panel meter agrees with Wattmeter. VR16 VR21A Key TX & adjust for 1-3 Watt output VR21A S-3 only RF METER: Set mode to AM, MIKE GAIN at minimum.Ĭonnect wattmeter to ANT output. Damage to power transistors and inability to achieve 100% modulation from insufficient audio power will result. VR13 Key TX adjust for for 8-10 watts CAUTION! Do not exceed this level. AM CARRIER POWER HIGH: Set mode to AM, MIKE GAIN at minimum.
