18-1 Setting the RS232 parameters
The RS232 parameters may be altered using the “REMOTE” option in the
CONFIGURATION menu.  This is accessed in EXPERT status by pressing the
[FUNC] [LOCAL] keys.
Make sure that the EXPERT status is selected, if not use the UP/DOWN key to
move the cursor alongside the “NEWUSER” option and rotate the [DIAL] so
that the legend “EXPERT” is displayed.
Press the [DOWN] key until the “REMOTE” menu is
displayed.  There are two parameters which may be...

(19)  Clone (copy) data between two AR8000 receivers
It is possible to clone (copy) selected or ALL data from one AR8000 to another
AR8000 receiver.  This is a useful facility when two friends each have the
AR8000 receiver and wish to share data.
The optional CU-8232 interface is
required along with the necessary
cables for connecting two AR8000
receivers together.  Further
information will be provided with
the optional CU-8232 interface unit.
There are two levels of clone...

Make sure that the EXPERT status is selected, if not use the UP/DOWN key to
move the cursor alongside the “NEWUSER” option and rotate the [DIAL] so
that the legend “EXPERT” is displayed.  Press [ENT] to accept the changes.
The process of copying specific data is initiated using the “SET COPY” menu
which is accessed by pressing [FUNC] [0] while in EXPERT status.
Use the [DIAL] to select “SEND-MODE” for the receiver which will SEND the
data and “RCV-MODE” for the receiver which...

Both  “A” & “B” VFO frequencies will reset to 80.000 MHz and mode/step will
be set to AUTO.
Search/scan bank linkage and select scan data will be lost but the memory
contents will be retained.  The pass channels will be off, pass frequencies will
be deleted and password will be cancelled.
DO NOT USE THIS KEY SEQUENCE UNLESS ABSOLUTELY NECESSARY.
Search / scan data will need to be manually keyed into the receiver unless the
SYS-DATA has been previously cloned (copied) to...

transmissions (you can usually remove the aerial to determine this).
Alternatively the AR8000 (like all receivers) will produce spurii in certain places
such as 76.8 MHz and 49.725 MHz as examples.  You may use the PASS and
AUDIO SCAN/SEARCH facilities to reduce their annoyance to a minimum.
The display blinks and changes
Ensure that the PRIORITY facility is not engaged.  If it is, a letter “P” will be
displayed on the first line of the LCD.

“FREQ ERROR”
This error message will be displayed if you attempt to key in a frequency
outside of the acceptable range of 0.1 MHz (100 kHz) to 1900 MHz.  The
frequency will revert to the original display and you may re-enter a new
frequency.
“PLL ERROR”
This indicates that the PLL (Phase Lock Loop) has unlocked.  This is the
system used by the receiver to select and change frequency.  Ensure that you
have not set the “special” PLL LOCK DETECT inappropriately [FUNC] [1] while...

WA7000 wide band active whip aerial
Compact aerial designed for installation where space is a problem.  The
WA7000 is active on the lower frequency band 30kHz to 30MHz and passive
on the higher band between 30MHz to 2000MHz.
DA3000 VHF-UHF discone aerial
16 element VHF - UHF discone aerial with useable coverage of 25 MHz to
2000 MHz.  Supplied with cable and connectors etc.
ABF125
VHF civil airband filter to reduce the chances of breakthrough especially from
powerful VHF...

Long wire aerials
For shortwave reception a random length of long wire approximately 10 to 20
metres in length forms a good compromise.  The wire should be connected to
the centre pin of a BNC plug then connected to the BNC aerial input on the top
of the AR8000.
If possible try to locate the receiver close to a window so that the wire has the
shortest and most direct run from the rear of the receiver to the outside World.
Never attach the wire aerial directly to a support or...

As a compromise it may be worth making up a dipole aerial for a band of
particular interest and have a VHF-UHF discone plus second random wire for
general listening.
It is quite easy to make a dipole for shortwave, for that matter one can be
easily made up for VHF or UHF too.  If being made for VHF-UHF the centre
connection of the coaxial cable feeds the upper element set vertically.
Shortwave dipoles on the other hand are usually mounted horizontally
It is worth noting that...

Coaxial cables
When constructing dipole aerials or connecting VHF aerials 50 OHM coaxial
cable should be used.  For shortwave or short runs of VHF URM43, URM76
or RG58U is ideal,  for longer runs of VHF-UHF feeder it may be worth
considering a heavier URM67 or RG213 (or better!).
ATU & preselectors
Aerial tuning units (ATU) may improve the shortwave section of a wide
range receiver by rejecting unwanted signals and only allowing a specific band
of frequencies through.  These...
