c. Rf Tuning After Applying Rf Power.
The objective of using these tuning procedures is to bring the meter
needle on the band-pass filter to zero and have it remain there when
the transceiver is keyed.
To avoid equipment damage, complete rf tuning steps 1 through 5
within approximately 1 minute.
(1) Key the transceiver continuously to apply rf power while tuning.
(2) Adjust tuning knob A for minimum reflected power as indicated by a minimum reading on
mete-r. Adjust tuning knob B, and then tuning knob C, for a minimum reflected power.
