Automatic antenna selection

The transceiver covers 0.1–60 MHz over 10 bands.
Each band key has a band memory which can mem-
orize a selected antenna (ANT1, ANT2, ANT1/RX an-
tenna and ANT2/RX antenna). When you change the
operating frequency beyond a band, the previously
used antenna is automatically selected for the new
band. 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.
