Pin 3 on the ACC 1 connector on the rear
panel also allows you to connect an
independent keyer or computer to share CW
keying.
This would be useful if using the output of a
computer program for transmitting CW (like
contest logging software) while also desiring
a paddle to be connected to the radio for
using the internal keyer. Connect the CW
keying output of the computer logging
program to PTT pin (3) on the ACC 1 jack,
and then connect your paddle to the front
panel KEY jack. See the description of (31)
ACC 1 in Section 3 of this manual.
(4) MULTI ENCODER
The front panel MULTI knob is used for
adjusting a variety of transceiver functions.
Pushing various buttons on the
circumference of the screen enables
functions that are then value-adjusted by the
MULTI knob. Display letters in green on the
transceiver screen indicate the item being
adjusted. Example: pressing the PWR
button to adjust power changes the green
display to read POWER
MULTI knob adjusts power level up or down.
Example 2: pressing the NR button
changes the green display to read SET NR.
The NR value is shown just above the NR
button.
Several items that are found inside the
transceiver menu are adjusted using the
MULTI knob. These items can be accessed
by pressing the MULTI encoder towards the
front panel of the transceiver. The OMNI-VII
will cycle through various menu items
allowing them to be adjusted without
accessing the menu itself. Note not all
menu items are accessible via this method,
and that the all-mode squelch control is
ONLY available via this control method.
(5) PBT/BW ENCODER
Receiver bandwidth (BW) and passband
tuning (PBT) are adjustable using this
encoder.
To adjust BW or PBT value: A green LED
indicator is next to the BW and PBT legends
on the front of the radio above the encoder.
Press the encoder to switch between BW
and PBT.

Second release – August 2007
The BW control is used to set the value of
the DSP bandwidth filters. A value for each
filter is shown on the screen next to the
encoder itself. BW 2800 indicates a DSP
bandwidth value of 2800 Hz. There are 38
selectable DSP filters from a minimum of
200 Hz to 12 kHz maximum. Filtering is
selectable independent of mode.
The BW control can also be used to
automatically engage or disengage the 455
kHz I-F filters. See I-F FILTER in Section 4
of the manual.
If manual selection of I-F filters is done,
please note that the DSP BW filters are
locked out at bandwidths above that of the
manually selected I-F filter. Example: If the
2.5 kHz I-F filter has been selected manually
in the menu system, the DSP BW maximum
value will be 2500 Hz. All filters from 2500
Hz and down will be available. See I-F
FILTER in Section 4 of the manual.
PBT is adjustable + or – 2.5 kHz from
center. PBT can easily be cleared to zero.
When the PBT LED is lit next to the
encoder, press the encoder in and hold for
two seconds. The PBT value will revert to
zero.
(6) AF/RF ENCODER
AF GAIN (AUDIO) and RF GAIN are
adjustable using this encoder.
Press the encoder to toggle between the two
items. Turn the knob clockwise to increase,
counter-clockwise to decrease.
Values for AUDIO and RF GAIN are shown
in blue on the screen next to the encoder.
Limiting receiver sensitivity with the RF
GAIN control is also reflected on the s-
meter.
For true manual control of receiver gain, turn
AGC to OFF and use the RF GAIN control to
limit receiver response.
(7) MIC
Front panel jack used for connection of a
microphone. The OMNI-VII features the
common 8 pin microphone jack used by
many amateur radio transceivers. Most
dynamic or electret microphones can be
used. When adapting a microphone, please
refer to the wiring diagrams in Figures 2-2
and 2-3.
