Infrared controller
5-24 Filter change key 
One of a group of six keys contained within an outline, the
 key chooses filter selection for subsequent change
with the 
 and  keys. When  is pressed
the receiver briefly displays the legend Filter along with
the sequence number (1 to 6) of the current filter (the
standard receiver displays 1 to 4 because it is fitted with 4
filters). This message is displayed for about 5 seconds
then the display returns to its...

5-30 Volume increase and decrease keys
 
 
These two keys allow the volume of the receiver to be
varied between minimum and maximum. They will auto-
repeat if held down for more than half a second.
5-31 Store into memory key 
The  key is used to store the current receiver
frequency and mode into the current memory channel.
The legend Stored .. on the receiver’s display confirms
operation, and appears for about 5 seconds in the top left
corner. Keying in a memory...

6 Receiver operation - Main functions
It may be useful to refer to the overview and quick
reference guides in section 2 of this manual whilst working
through this section.
6-1 First switch-on
Connect an appropriate aerial to the input on the rear of
the receiver and make sure that the ANTENNA SELECT
switch is correctly set. The selection of aerial depends
upon your location and specific requirements but may
include a dipole or long wire.
Plug the d.c. cable of...

Typical displayed bandwidths for the optional Collins
filters are:-
Collins 500 Hz Displays as 0.7 or 0.8kHz
Collins 2.5 kHz Typically displays as 2.3 kHz
Collins 4.0 kHz Typically displays as 3.5 kHz
When the filter setup is complete, the receiver’s display
returns to frequency readout.
6-3 Memory restoration
If the data retention battery is discharged (refer section 6-
1) then some of the setup memories may contain rubbish
which will cause unusual operation of...

Used to backspace frequency entry from
the right hand side, each additional press
of this key deletes one further figure. This
is useful for correcting a mistake without
the need to re-enter the whole frequency.
Frequency entry using the infrared controller is accepted
in the range 0.051 MHz (actually 50.977 kHz) to 32 MHz
(actually 32.01672 MHz). Frequencies above the specified
top limit up to about 44 MHz will result in the receiver
tuning to the top frequency...

Other permutations are also accepted:-
  
or       
or      
The LCD briefly confirms entry as Step 05.00 in the top
left of the LCD to show that the entry is accepted as a
step size and not a frequency to tune to.
Each time the keys  or  are pressed, the
receiver will step up or down by 5kHz (as this is the step
size currently selected). The LCD frequency readout
changes as the receiver tunes to new frequencies. You
may hold down the 
 or  keys for
continuous...

The setting of AGC speed is important for SSB reception.
Usually a SLOW setting provides the best results when
background noise will usually be reduced. Select the 2.2
kHz IF filter and experiment with the AGC and IF GAIN
for best results. If splatter is encountered from adjacent
channels, it may help to reduce the bass audio tone control
to -5 and the treble control to no more than +2.
When listening to amateur band nets and wishing to keep
background noise to a...

Manual synchronous AM : If you prefer to be in total
control, the automatic synchronous AM system may be
switched off and a manual system used in its place with
selectable wide and narrow bandwidths.
From the SETUP menu (press the 
 button if Setup
is not displayed above the spin-wheel) choose 
 to
go the to CONFIGURE menu.
Rotate the spin-wheel until the display indicates
Sync detector:
Pressing the soft-key on the right will change the
synchronous detector...

To restore an S-meter display, press the  button.
VFO-A and VFO-B and each mode may have different
filter selections in order to provide the greatest flexibility,
especially when moving between AM and SSB while
DXing using ECSS.
6-7 Passband Shift (PBS)
The AR7030 is fitted with a powerful system to help
eliminate the effects of adjacent channel interference by
shifting the passband of the IF filter upward or downward
in frequency. PBS operates in all modes...
