RECALL SUB does not need to be set to
ON to save the VFO B frequency, FM
CTCSS tone, and split into memory. The
memory system will do this automatically.
They will not be recalled until RECALL SUB
is set to ON.
SIDETONE FRQ
Available settings: 0-1270 Hz in 10 Hz
steps.
The SIDETONE FRQ menu line item is used
to set CW sidetone and the autotracking CW
offset frequency.
Pressing and holding the SPOT button will
produce a tone at the SIDETONE FRQ
value set by the operator. This tone can be
matched to the received tone of an on-air
CW signal to achieve zero beat. Press and
hold the SPOT button while tuning in a CW
signal. When the tones match, you are on
the proper frequency.
This menu line item is also adjustable from
the front panel without entering the menu by
pressing ALT then S-T. See
(28) SPO/S-T
in Section 3.
SIDETONE VOL
Available settings: 0 to 100%.
SIDETONE VOL duplicates the S-T
adjustment that is selectable by pushing the
SPO/S-T button on the front panel. See
(28)
SPO/S-T
.
SPOT VOLUME
Available settings: 0 to 100%.
SPOT VOLUME duplicates the SPOTVOL
adjustment that is selectable by pushing the
SPO/S-T button on the front panel. See
(28)
SPO/S-T
.
CW QSK DELAY
Available settings: 0 to 100%
CW QSK DELAY allows slowing down or
partially defeating the full break-in CW
capability of the OMNI-VII.
A higher value represents more
transmit/receive delay between individual
transmitted CW characters. A setting of 0%
is full break-in CW. A delay of 100% is
approximately a 1 second recovery time
before receive audio is restored.
Please note that this control is not used for
“hanging” the transmitter for keying an
external linear amplifier. That function is
done with
EXT T/R DELY
, described
elsewhere in this section.
CW WEIGHTING
Available settings: 0 to 24%
CW WEIGHTING refers to the length of a
space between two transmitted dits in CW
versus the dit itself. At a setting of 0%, the
transmitted dit and the space after it are of
equal length. Adjusting this value upward
subtracts length from the available space
and adds it to the dit, to make the dit length
longer and the space between characters
shorter. The upper value of 24% refers to
24% of the space time being added to the
transmitted dit. Higher values past 24% (if
they had been made available) would
continue to shorten the space until all that
was transmitted is a continuous carrier at
100%.
CW KEYER
Available settings: OFF, MODE A, MODE B
The OMNI-VII’s internal keyer can be
configured for either Curtis mode A or mode
B keying. Turn the MULTI knob to select or
to turn the keyer off.
The difference between mode A and B is
what the keyer does when both
paddles are released after being squeezed
at the same time. Mode A completes the
element being sent when the paddles are
released. Mode B sends an additional
element opposite to the one being sent
when the paddles are released.
The basic difference between the modes
can be described by sending the letter C in
Morse Code. In mode A, squeeze both
paddles (dah before dit) and let go of both
