Printed in USA
With the transceiver VFO A on 14.195.000,
press A=B. Now both VFO’s are on
14.195.000. Press and hold the REV button
while turning the main tuning knob. When
the display reads 14.200.000, release the
REV button. Now press SPL to engage split
frequency operation. The icon that reads
“Tx” next to the VFO A display will drop
down next to the displayed VFO B frequency
and the VFO B frequency will change to red
digits. You are now ready to transmit on
14.200 MHz and listen on 14.195 MHz.
When a DX station in this example is
“listening up 5 to 10”, it may be useful to
listen to your TRANSMIT frequency in
between DX station transmissions to
ascertain where the DX station is listening.
By pressing the REV button, you can listen
to your transmit frequency. As above, you
can also move the main tuning knob to tune
around while holding the REV button.
Release REV, and you are ready to
transmit.
EXTERNAL CW INPUT PLUS CW
KEYER OPERATION FROM
PADDLES
Some contest logging programs use
computer generated CW for transmission of
contest data (CQ’s, reports, etc.) but do not
employ the ability to send CW through any
device other than input from the computer
keyboard.
It is useful in this situation to be able to have
both an external keyer (in this case, the
computer) and the internal keyer in the
OMNI-VII both simultaneously available.
The “external keyer” is used for contest
CQ’s and information, while a paddle
connected to the internal keyer can be used
by the operator for quickly repeating
necessary information.
Pin 3 on the ACC 1 connector on the OMNI-
VIII rear panel is a PTT connection. In CW
modes, this can allow the radio to be keyed
by an external device in CW mode.
DRAG ADJUSTMENT FOR THE
MAIN TUNING KNOB
The main tuning knob is equipped with a
drag
control. To adjust the drag on the main
tuning knob, hold the silver skirt still while
rotating the knob about a quarter turn.
There will be a gentle “click” feel as the knob
is loosened or tightened. Counter-clockwise
twisting will loosen them and clockwise
twisting will increase the drag. Loosen them
up or increase the drag to your preference.
MASTER RESET
On rare occasions, it may be possible to
confuse the microprocessor in the
transceiver to the point where a master reset
may be necessary to restore operating state.
A master reset often needs to be done after
an upgrade for the transceiver is sent via the
serial port interface (see
UPDATING OMNI-
VII FIRMWARE
elsewhere in this section).
To perform a master reset, turn transceiver
power off. Press and hold the MNU button
down. Turn transceiver power on, and
continue to hold the MNU button until the
message “MASTER RESET” appears
towards the upper left of the radio screen.
This should take about 5 seconds after
turning radio power on.
UPDATING OMNI-VII FIRMWARE
Like other Ten-Tec transceivers, the
firmware in OMNI-VII is Flash-ROM
