Peak Mode On/Off:
The Power display on the LED bargraph can display either average
power or peak forward power, in watts. Average mode is suitable for 100% duty cycle modes
such as FM, RTTY, or PSK. Peak mode is more useful on modes with varying duty cycle such as
SSB or AM. The factory default is average mode.
To toggle between power display modes, press
Func -> C Up
(Press and release
Func
, then
press and release
C Up
). Peak mode is indicated by a falling meter display, with the highest
power shown as a steady LED while the remaining LEDs fall back to zero. Average mode shows
the same display, but without the steady LED showing. Press
Func -> C Up
repeatedly to toggle
between Peak and Average modes.
