AR8600
Mark2
RECEIVER
- any time, any place
wider coverage all mode receiver 100 kHz - 3000 MHz with RS232 port
The AR8600
Mark2
is an amazingly versatile receiver which can be used mobile, base or trans-portable... powered from
an external 12V d.c. power supply, 12V vehicle or from an optional internally fitted NiCad battery pack. Due to continuous
development of our products, the AR8600
Mark2
has been enhanced in several areas. The upper frequency range has
been extended to 3000MHz (3.0GHz), lower band sensitivity has been increased (now officially covering to 100kHz) with
an enhancement to short wave performance by the addition of further bandpass filters and selection of alternative I.F.
filters. Mini-Circuits RMS1 / RMS2 mixers have been employed with active SPM aerial switching devices
(not diode-switching) abundantly employed throughout the signal path. The AR8600
Mark2
provides remarkable short
wave performance, making other similar wide band competitors mediocre by comparison.

DELAY, AUDIO, LEVEL, MODE
l RS232 computer socket
l Flash-ROM memory (no battery required)
l Slot card sockets
l BNC socket for 10.7MHz i.f. output
A strong twin metal case with die cast front panel characterises the multi-purpose role.
All mode receive capability is provided including Single Side Band with programmable
tuning steps down to a resolution of 50Hz with the frequency established by a highly
accurate Temperature Compensated Crystal Oscillator (TCXO). An RS232 port
further extends the capabilities with free supporting control software available from the
AOR web sites.
Many microprocessor features have been adopted from the trendsetting AR8200
Series-2 hand portable receiver, with the addition of a lamp dimmer and squelch
operated lamp. The AR8600
Mark2
RF front-end is an all new design with additional
RF bandpass filters, sharper I.F. filters, SPM aerial switching devices for minimal signal
path loss and Mini-Circuits mixers. RF preselection is provided through the crowded
areas of VHF and UHF to ensure the highest levels of adjacent channel rejection with
software spurii cancellation. In addition to a hinged telescopic whip aerial, the AR8600
Mark2
is supplied with a detachable plug in medium wave bar aerial which locates
on the rear chassis of the receiver for localised medium wave monitoring. An additional
BNC socket is mounted on the rear chassis so that 10.7MHz i.f. output may be
extracted for use with external spectrum display and vector analyser units such as the
AOR SDU5500. The TCXO ensures high stability with minimal internal spurii and is
usually only seen in top of the range (more expensive) table-top models such as the
AR5000 and AR7030.
Centre stage is a custom multi-section back-lit LCD, numeric keypad, navigation keys,
rotary tuning control and separate controls for volume and squelch control, the LCD
can also display 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.
