11-3 Measuring SWR
The IC-746 has a built-in circuit for measuring antenna
SWR while in SSB mode — no external equipment or
special adjustments are necessary.
Make sure the antenna whose SWR you want to mea-
sure is connected, that output power is set to 30 W or
more and that [TUNER] is OFF.
➥
While pushing [PTT], speak (a single, even pitch)
into the microphone.
• The measured SWR appears in the display.
• When the SWR reads higher than 1.5, antenna adjust-
ment is necessary.
