The SWR Bargraph shows the frequency, SWR, forward power, and SWR bar meter. The 12-block (31-
segment) SWR bar meter indicates SWR of 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6-1.7, 1.8-2.0, 2.1-2.5, 2.6-3.0,
3.1-5.0, 5.1 to infinity. The numeric reading of forward power appears at the end of the bar meter. There
is also an audio SWR indicator (see “SWR Beep Menu” section on page 14).
Figure 5 SWR Bargraph
L-Network Menu
Shows the configuration of the L-network matching circuit, SWR, and forward power. The antenna
symbol, on the upper left corner, indicates the antenna side of the L-network. The capacitance value is
displayed to the left when it is on the antenna side and to the right when it is on the transmitter side.
Inductance value is shown in microhenries (
µ
H) and capacitance value in picofarads (pF). The numeric
reading of forward power appears at the lower right corner of the display. See “Manual Tuning” on page
14.
Tuner Indicators
