only one may be fitted at a time.  It’s fitting is recommended in a workshop.
The frequency limits of the VHF converters are:
108.00000 MHz to 139.99999 MHz
or
140.00000 MHz to 169.99999 MHz
Optional SSB filter
USB/LSB/FAX modes use a 2.4kHz Murata ceramic filter.  An optional
Collins 2.5kHz eight resonator mechanical filter ((526-8635-010) of higher
specification may be fitted into the normal position replacing the 2.4kHz filter
(workshop fitting).
Optional CW filter

Computer control software
A hands off IBM-PC computer program is planned to control the AR3030 via
the RS232C port.  A separate serial connecting lead will also be required.
LA320 loop aerial
Desktop active loop aerial for portable operation away from a base aerial such
as when while travelling on business or holiday.  Frequency coverage is 1.6 to
15MHz with optional elements to cover 0.2 to 0.54MHz and 0.54 to 1.6MHz.

and locate a small hole in the bottom cabinet close to the main rotary tuning
control.  This hole provides access to the microprocessor reset switch.
With the AR3030 connected to it’s power supply and switched On,
momentarily press this switch and release using preferably a non conductive
thin probe such as a cocktail stick or cotton bud.  This action will reset the
microprocessor.
Should the receiver fail to power up,  check the power supply and mains fuse.

aerial input should the VHF converter option be fitted.
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 fed into the high impedance aerial input of the AR3030
receiver.  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...

receiver like the AR3030 is that for the ultimate results many dedicated aerials
are required to cover the whole spectrum.  This may involve complex aerial
switching and reduces the ability to quickly monitor many bands.
As a compromise it may be worth making up a dipole aerial for a band of
particular interest and have a 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 should you have...

noise is introduced into the receiver.
Loop Aerials
Desk-top loop aerials have the advantage of small size (such as the AOR
LA320).  They too have tuning controls to reject unwanted signals.  As the
loop is within easy reach of the operator it can be rotated to provide directivity.
They can be particularly useful for DX’ing the lower bands.
Generally speaking they offer excellent portability but cannot compare on the
higher bands with a well sighted long wire aerial.
