Operating Band Selection
This transceiver covers an incredibly wide frequency range, over which a number of different operating modes are used.
Therefore, this transceiver’s frequency coverage has been divided into different operating bands, each of with has its own
pre-set frequency steps and operating modes. You can change the channel steps and operating mode once you get started,
of course, per the next section.
To change the frequency band, press either the BAND(DWN) or BAND(UP) key to move to the next lower or higher
operating band, respectively.
VFOa and VFOb are independent VFOs, so they may be set to different bands. See the “Stacked VFO System” discussion
on page 22 for details.
Menu Quick Start
Many aspects of this transceiver’s configuration may be customized using the convenient “Menu” system, which allow
you to configure many “set and forget” settings just the way you want to. A full discussion of the Menu system begins on
page 52; for now, here is a brief discussion on how to change Menu settings:
1. Press and hold in the [F] key for one second to enter the Menu mode.
2. Rotate the MEM/VFO CH knob to recall the Menu Item to be changed (for example, Menu Mode No-001 [EXT
MENU], which Enables or Disables the “Extended Menu” Mode).
3. Rotate the DIAL knob to set this feature (in this example, the default setting is “OFF (Disabled),” so rotate the DIAL
knob to set this feature to “ON” (Enabled).
4. Press and hold in the [F] key for one second to save the new setting and exit to normal operation.
If you have momentarily pressed the [F] key to enable the changing of the function of the Multi Function keys ([A], [B],
and [C]) by the MEM/VFO CH knob.
Mode Selection
Press either the MODE(<) or MODE(>) key to move among the eight settings for the operating modes, respectively.
where “CWR” is “CW-Reverse,” using the opposite sideband from the “default” BFO injection sideband (in most cases,
the default injection sideband is on the “USB” side); “DIG” is an AFSK-based Digital mode, set up per Menu Mode No-
038 [DIG MODE]; and “PKT” represents either 1200 or 9600 bps FM packet.
You can set VFOa and VFOb to different modes in the same band, allowing you to have a “Phone” VFO and a “CW”
VFO, for example.
Adjusting the Audio Volume Level
Rotate the AF knob to set a comfortable listening level.
