An accurateDC voltmeter with a full scale of at least 10 volts isrequired. Connect the + lead of the voltmeter to theterminal located directly below VR2 at the top of theautomatic voltage regulator board. Connect the — lead tothe chassis and adjust VR1 for a voltmetér reading of 9volts.5.4 TRANSMITTER SECTIONCARRIER LEVEL AND CARRIER BALANCE(See Fig. 17)Set the rear panel SG SW switch to OFF.

Set theBAND switch to 28.5 and set the main tuning dial to28.8 MHz. Next tune the transceiver for maximum out-put. Now set the SG SW switch to OFF and measure theoutput at the antenna terminals with a sensitive highfrequency voltmeter. Adjust the neutralizing capacitor TC1(mounted on the side panel of the final amplifier shieldingbox) for minimum output. Normally the shielding boxdoes not have to be removed for neutralization.L3(14)DRIVE COILUNITshow the band.Coil Location Diagram
