(1) Introduction & accessories
Thank you for purchasing the AOR AR3030 General Coverage Receiver. The
AR3030 uses the very latest DDS (Direct Digital Synthesizer) technology to
ensure the highest levels of design, performance and reliability.  A TCXO
(Temperature Compensated Crystal Oscillator) is provided for high stability
and the legendary Collins 6kHz AM filter for the ultimate in AM selectivity.
It is recommended that you carefully read this handbook and familiarise...

(3) Major features
General
The AR3030 offers the very latest technology through use of its’ DDS (Direct
Digital Synthesizer).  The legendary Collins 6kHz AM filter is fitted as standard
to provide the highest levels of AM selectivity.  High stability is accomplished
by the standard fitting of a TCXO (Temperature Compensated Crystal
Oscillator).
As the model name would suggest,  the tunable coverage is 30kHz - 30 MHz
(with 29.999995 MHz being the actual upper limit of tuning)...

One converter may be internally fitted to further extend the receive coverage of
the receiver.  A separate 50 OHM BNC aerial socket is fitted to the rear case of
the AR3030 in order to simplify connection to a dedicated VHF aerial.
SSB (Single Side-Band) - who uses it?
SSB is a general term given to two additional modes of operation USB for
upper-side-band and LSB for lower-side-band.  Generally speaking, SSB is
used by long range services such as oceanic airband, ship to shore...

optionally fitted (workshop fitting) to replace the 2.4kHz filter. Should the
narrow CW optional PCB position not be used,  it is possible to fit the optional
Collins 2.5kHz filter as an addition which will be selected in the narrow
position.
CW
2.4kHz Murata ceramic filter in the Normal position.  An optional 500Hz/-3dB
Collins seven resonator mechanical filter (526 8634 010) may be optionally
fitted (workshop fitting)in the Narrow position.

There is a massive EEPROM store for all memory channels and VFO data
so that no memory backup battery is required.  The memories may be over-
written time and time again.
RS232 computer port
A 9 pin D type socket is fitted to the rear case,  this will permitcontrol of many
receiver facilities via a computer.
Loudspeaker and audio output
The AR3030 has a built-in 66mm 3 WATT loudspeaker.  A 3.5mm jack socket
is located on the rear panel of the receiver for external speaker...

4-1 Location
Do not use or leave the receiver in direct sunlight.  It is best to avoid locations
where excessive heat,  humidity,  dust and vibration are expected.  Always
treat the receiver with care.
Take care to avoid spillage or leakage of liquids into the receiver and AC
power supply.  Special care should be taken to avoid liquid entering via the
power jack.  Always remove batteries if the receiver is not going to be used
for a while.
Avoid static discharge from wire...

The AR3030 power supply has no connection to the EARTH pin of the mains
plug.  However a separate earth point is provided on the rear panel of the
AR3030 for connection to a water pipe, central heating system radiator or
external earth rod.  If fitting a separate external earth rod,  consider the
implications carefully is your mains supply uses Protective Multiple Earth
(PME) system.  If in doubt consult an expert electrician.  Never earth to a
gas pipe!
Always disconnect the...

An ATU can improve the selectivity of any shortwave receiver when connected
to long wire aerial other than a short wire of a few metres.  This valuable extra
selectivity is created provided by the ATU rejecting out of band signals
enabling the receiver to “single out” one band of frequencies while rejecting
potentially strong unwanted transmissions.
An ATU is usually constructed in a small box with about two or three controls
on the front panel.  One disadvantage however is the...
