Operation Manual

■ Automatic antenna selection
The transceiver covers 0.03–60 MHz over 10 bands.
Each band key has a band memory which can mem-
orize a selected antenna (ANT1, ANT2, ANT1/RX
antenna and ANT2/RX antenna). When you change
the operating frequency beyond a band, the previ-
ously used antenna is automatically selected. This
function is convenient when you use 2 or 3 antennas.
To use the band memory, enter set mode and con-
firm that “Auto” is selected as the [ANT] switch item.
(p. 130)
• Antenna selection mode: “Auto” (default)
The antenna tuner ON/OFF condition is also memo-
rized in the band memory.
[Example]: a 3.5/7 MHz antenna is connected to
[ANT1], a 21/28/50 MHz antenna is connected to
[ANT2]. When the antenna selector function is set to
“Auto,” an antenna is automatically selected when the
transceiver changes bands.
• Antenna selection mode: “Manual”
[ANT] (MF1) functions, however, band memory does
not function. In this case, you must select an antenna
manually.
When using an external antenna selector for more
than 3 antennas (except for receive antenna),
“Manual” should be selected as the [ANT] switch set
mode item. (p. 130)
NOTE: When “Auto” or “Manual” is selected, the
antenna tuner ON/OFF condition is consistent with
[ANT] (MF1).
• Antenna selection mode: “OFF”
[ANT] (MF1) does not function and [ANT1] is always
selected.
