(16) AGC

Automatic gain control (AGC) is used to
provide a uniform output at the audio level of
varying signal strengths that appear at the
input of the receiver I-F chain.
Generally, SLOW and MED are used for
voice modes, and MED or FAST for CW
mode. Advanced users may want to disable
AGC altogether by selecting OFF and
control the receiver gain manually using the
RF GAIN control – see (6) AF/RF
ENCODER as described elsewhere in this
manual.
To select AGC setting, press the AGC
button to cycle through the available
.
choices OMNI-VII has four selectable AGC
settings: OFF, SLOW, MED, and FAST.
(17) BAND CHANGE AND DIRECT
FREQUENCY ENTRY KEYPAD
The 11 available amateur radio bands
useable by OMNI-VII are delineated in white
print on the band change keypad buttons.
To select one of the 10 HF amateur bands
or the 50 MHz band, press the appropriate
band button.
The last mode and setting of DSP BW are
recalled for that band when moving from
band to band. The last bandstacking
register in use on that band will also be in
use.
OMNI-VII is equipped with four bandstacking
registers. Bandstacking registers allow
various combinations of mode and filter
bandwidth on the same amateur band to be
"stored". To access the registers, press the
appropriate band change button for a band
already in use. When using 28 MHz, for
example, press the 28 MHz button again.
The four bandstacking registers are labeled
on the screen as A B C D just to the lower
left of the band change keypad.
Direct frequency entry is possible for the
main VFO using the keypad. To direct enter
a frequency, press ENT. The main display
will change to a series of green dashed
lines. Enter the frequency using the
numbers and decimal point. If entering a

frequency followed by a series of zeros, the
zeros can be automatically entered by
pressing ENT again to finish the entry.
Example: To move to 14.200.000, press
ENT, 1, 4, 2, ENT and the frequency display
will fill out to 14.200.000 automatically.
(18) A=B, A>B, SPL, REV
These four buttons control VFO A and B
functions on the transceiver.
The large main frequency display on the
screen is always VFO A – the smaller
frequency display below it is VFO B.
A=B takes the frequency and mode
information from VFO A and transfers it to
VFO B. The mode display for VFO B is
shown immediately to the right of the smaller
frequency display.
A/B flips the frequencies and modes
between the two VFO's.
SPL is used for split frequency operation.
Press SPL and the VFO B frequency display
turns to red and the Tx indicator on the
screen moves next to it. In SPLIT mode,
receiving is always on VFO A and
transmitting is always VFO B.
When in split mode, the REV button allows
monitoring and/or tuning of VFO B while the
button is held down. Press and hold to
monitor VFO B. The main tuning knob can
also be turned while holding down the REV
button to adjust frequency.
Notes: The REV function can be used even
when OMNI-VII is not in split mode if
momentarily monitoring the VFO B
frequency is desired. When REV is in use,
the A=B and A/B buttons are disabled.

(19) MAIN TUNING KNOB

The large tuning knob is for adjusting
frequency when the transceiver is in normal
use.
When the transceiver menu system is
enabled, the main tuning knob is used to
scroll up and down through the various line
items. See also (20) MNU.
