SW 1 RF ALIGNMENT
STEP SIGNAL SOURCE (SW Signal Gen.) CONNECT TO SET SIGNAL TO ALIGNMENT INDICATOR (Oscilloscope, VTVM) CONNECT TO
1 (modulated) (Lowest end) (Osc. coil)
2 A standard radiation (modulated) Across speaker (Highest end) (Osc. trimmer) Maximum control at
3 (modulated) 5.9 MHz (ant. coil)
