8 ANTENNA TUNER OPERATION ■ Automatic antenna selection The transceiver covers 0.03-60 MHz over 10 bands. Each band key has a band memory which can memorize a selected antenna (ANT1, ANT2, ANT1/RX antenna and ANT2/RX antenna). When you change the operating frequency beyond a band, the previously 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 confirm that "Auto" is selected as the [ANT] switch item. (p. 130) • Antenna selection mode: "Auto" (default) The antenna tuner ON/OFF condition is also memorized 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.
