AR8200 Series-2 -

The Superior Concept

never before has one hand portable offered so much

The AR8200 represented a beacon when first released building on

the successful recipe of the AR8000 and technology developed for

the award winning AR5000 base receiver. Technology marches

forward with the AR8200 SERIES-2 keeping the innovative concept

and forward thinking alive and bright. It has not been easy improving

on what many thought to be the ultimate, however the AR8200

SERIES-2 does provide even more with nothing taken away.

A Temperature Compensated Crystal Oscillator (TCXO) now forms

the heart of the AR8200 SERIES-2, this ensures high stability with

minimal internal spurii... the TCXO replaces a crystal reference as

commonly employed in other receivers and is usually only seen in top

of the range (more expensive) table-top models such as the AR5000

and AR7030. Performance too has seen the AOR R&D team fine

tuning the design for best sensitivity and strong signal handling

over the extremely wide coverage of 530kHz to 2040MHz (all mode

receive without gaps). The standard aerial has been replaced by a

telescopic whip on a swivel base, this ensures the best results, a

medium wave bar aerial is also provided as standard. The design

team have certainly been taking account of customers wishes, the

keyboard ZERO key has been swapped in position with the DECIMAL

to match the telephone layout, LCD illumination has been increased

(for improved visibility) and following requests for longer operation

between charges, the 4 x AA size NiCads have been increased

in capacity, again reflecting improvements in modern technology.

The obvious change has been left for last... the cabinet colour has

been changed from green to black !

The list of features is vast, large multi-section backlit LCD, side

mounted navigation keys and rotary tuning control, alpha-numeric text

comments.

The all important 8.33 kHz airband channel step is

correctly

implemented

(eight-and-one-third, 33, 66, 00). Channel steps are

provided in a menu and may be programmed. Step may be

programmed by the operator in any receive mode using multiples of

50 Hz in any mode (i.e. 5 kHz, 12.5 kHz or even 1.25 kHz).

Extensive step-adjust and frequency offset facilities are also

provided (as per AR5000) to ensure tracking of the most obscure

band plans, AFC (Automatic Frequency Control) is included for spot on tuning ensuring that

nothing is missed. A wide frequency coverage is available from 530 kHz to 2040 MHz

(no gaps) with actual minimum acceptable frequency of 100 kHz.

The RF front-end is preselected around VHF to ensure the highest levels of adjacent channel

rejection with software spurii cancellation. The short wave bands are converted directly to an

IF of 45 MHz to remove compromise and the AR8200 SERIES-2 is supplied with a

detachable plug in medium wave bar aerial for localised monitoring with a negative

feedback circuit employed.

All mode receive: WFM, NFM, SFM (Super Narrow FM), WAM, AM, NAM (Wide, standard,

Narrow AM), USB, LSB & CW. A 3.0 kHz SSB filter is employed with true carrier re-insertion

resulting in non-offset frequency readout for easy tuning of SSB transmissions. An attenuator

and noise blanker are also featured. A meaningful band plan is factory programmed specific

to market area, this ensures that the AR8200 SERIES-2 automatically selects the correct

receive mode and tuning step (although mode and tuning step may be manually selected at

any time), the band plan may be edited via computer control.

The side keypad provides four arrow keys presented as a single ‘rocker’ resulting in

more natural and intuitive navigation through the on-screen menus.
