Next, enter the desired frequency using the numeric keypad (Numeric
Keypad). Entering 1 or 2 digits is interpreted as MHz; 3 or more digits
as kHz. You can optionally include one or two decimal points during
frequency entry (MHz and kHz).
To scan a selected range, you'll first need to create a frequency
memory with VFO A and B as the start and end points. The stored
value of VFO A's mode will be used. Next, hold [SCAN] to initiate
scanning**. This will mute the receiver. A long hold (~3 seconds) will
unmute the receiver and proceed with "live" scanning, which is useful
when listening for weak signals on a very quiet band.
Also see BAND SELECTION.
VFO Controls
Three switches above VFO A are used to control the VFOs:
[A/B] swaps all of the settings of VFOs A and B
[SPLIT] enters SPLIT mode (see USING SPLIT)
[REV] swaps VFO A and B settings until the switch is released. This is
useful for checking your transmit frequency in SPLIT mode when the
sub RX is turned off.
[A>B] copies the VFO A frequency to VFO B. A second tap of [A>B]
within two seconds copies all settings, including preamp, attenuator,
etc. If VFO A is on a different band than VFO B, then the RX and TX
antenna selections are also copied. (To enable independent band
selection for VFO B, set MENU:VFO B Different Band to YES.)
[B>A] copies the VFO B frequency to VFO A. A second hold of [B>A]
within two seconds copies all settings, including preamp, attenuator,
etc. If VFO B is on a different band than VFO A, then the RX and TX
antenna selections are also copied.
Sub Receiver and Diversity Mode
Tap [SUB] to turn on the sub receiver. When the sub is on, its
frequency is controlled by VFO B, except in diversity mode, where
