When a filter has been selected manually,
the DSP BW value cannot be adjusted
above that manual filter selection. Example:
If the 2.5 kHz filter is manually selected, the
highest available DSP BW is then 2500 Hz.
Note: Optional 500 Hz and 300 Hz filters
must be enabled in the menu before use.
See ENABLE 300 Hz, ENABLE 500 Hz in
the next sub-section.
ENABLE 300Hz, ENABLE 500 Hz
Available settings: YES, NO
Optional Collins™ mechanical 455 kHz I-F
filters at 500 Hz (model 2031) and 300 Hz
(model 2032) are available as options.
These filters must be enabled in the menu to
be used after installing.
After installation, turn the MULTI knob to
select YES for any filter installed.
Selecting YES for a filter that is not installed
will result in the receiver muting when that
filter is either manually selected or engaged
with the AUTO function under I-F FILTER.
An installed optional 500 Hz or 300 Hz filter
can be disengaged by selecting NO. For
example, if the optional 500 Hz filter is
installed, ENABLE 500 Hz is set to NO, and
I-F FILTER is set to AUTO, when turning the
BW control lower than 500 Hz the 500 Hz
I-F filter will not engage and will remain at
2.5 kHz.
How to install optional I-F filters is covered
under INSTALLATION OF OPTIONAL
COLLINS™ MECHANICAL FILTERS in
Section 5.
SQUELCH
Available settings: 0-100%
OMNI-VII is equipped with an all-mode
squelch that is accessible only from repeat
pressing of the MULTI knob; it is not shown
as a line item in the menu system. See the
description of (4) MULTI ENCODER earlier
in the manual.
The squelch control mutes receiver noise
until a signal of sufficient strength is
received, opening the squelch. This can be
useful for monitoring a calling frequency like
50.125 MHz on SSB or 10m FM repeaters
without having to listen to the constant
background noise of the band in use.

When the receiver is squelched, the legend
SQL will appear as a green rectangle on the
upper left of the screen, just above the PBT
value indicator.
