Section 4 – USING THE MENU
The OMNI-VII is equipped with a single
menu, accessible by pressing the MNU
button. It is our philosophy that most
frequently used controls on an HF
transceiver should be accessible via buttons
and knobs on the front panel while leaving
less often used items in a menu system.
Each line item in the menu will be described
in this section in the order they appear on
the menu screen, as of the initial release of
the transceiver firmware.
Press MNU to access the menu. Scroll
down through the menu items by using the
large main tuning knob. To change the
value on an individual line item, turn the
MULTI knob.
AUTO TUNER
Available settings: ON, OFF.
This menu item is used to turn on or disable
the optional internal automatic antenna tuner
(if installed). When set to ON, the tuner can
be activated by pressing the TUNE button.
When set to OFF, the tuner is disabled until
set to ON in the menu – it cannot be
reactivated from the front panel.
See
OPERATING THE AUTOMATIC
ANTENNA TUNER (IF INSTALLED)
in
Section 5 for complete autotuner
instructions.
TX METER
Available settings: PWR, SWR.
OMNI-VII has a power and SWR bargraph
meter on the screen. This bargraph meter is
used to display received S-units in receive
mode. In transmit mode, the meter can be
configured to show either power output or
SWR by toggling this menu option.
TRANSMITTER
Available settings: ON, OFF
OMNI-VII’s transmitter can be disabled by
changing this line item to OFF.
SSB TX BW
Available settings: 1000-4000 Hz in 200 Hz
steps.
The SSB TX BW control determines the
bandwidth of a transmitted SSB signal. It is
selectable in 200 Hz steps from 1000-4000
Hz. The upper and lower ends of the
transmitted bandwidth are determined by
this value and the TX ROLL OFF menu item.
Example: If SSB TX BW is set to 2400 Hz
and TX ROLL OFF is set at 200 Hz, the SSB
transmit response is 200-2600 Hz.
We recommend you read and understand
FACTORS THAT AFFECT THE SOUND
OF SSB TRANSMIT AUDIO AND THEIR
ADJUSTMENT
as described in section 5
before experimenting with this control.
TX ROLL OFF
Available settings: 70-300 Hz in 10 Hz
steps.
TX ROLL OFF determines where the low
end frequency response of an SSB transmit
signal begins to attenuate. It is selectable in
10 Hz steps from 70-300 Hz. Example: If
SSB TX BW is set to 2400 Hz and TX ROLL
OFF is set at 200 Hz, the SSB transmit
response is 200-2600 Hz.
We recommend you read and understand
FACTORS THAT AFFECT THE SOUND
OF SSB TRANSMIT AUDIO AND THEIR
ADJUSTMENT
as described in section 5
before experimenting with this control.
KEYING LOOP
Available settings: ON, OFF.
The KEYING LOOP menu item is used to
enable the TX EN / TX OUT QSK keying
loop as described in Section 3 under
(36 &
37) TX EN / TX OUT
. The interface
instructions for using these jacks are
provided there and in Section 5 under
CONNECTING A LINEAR AMPLIFIER.
Note: If the loop is turned ON and no
connections are made it will prevent the
OMNI-VII from transmitting.
AUDIO SOURCE
Available settings: MIC, LINE, BOTH.
The AUDIO SOURCE menu item is used to
determine which audio input is used for
