7. Rotate the INPUT, ANTENNA andINDUCTOR controls for maximumnoise or signal as heard on your re-ceiver. Refer to preset tuning chart onpage 12.8. Key your transmitter and adjust thepower level for a reading of 50-100watts on the FORWARD scale. Adjustthe INPUT, OUTPUT and INDUC-TOR controls for a minimum RE-FLECTED reading while maintaining a

FORWARD reading of 50-100 wattsusing your transmitter power control.9. Read the SWR on the red scale atthe point where the two needles inter-sect. Repeat TUNING the input andantenna controls until the lowest SWRreading is obtained. The SWR shouldbe 2:1 or lower.

This procedure takes patience the

first time. The input and antennacontrols vary the capacitors and provide fine adjustments. The roller inductor crank control providescoarse adjustment.
