AR8600 Mark2 ADDENDUM (paperwork V1.1)
Due to continuous development of our products, the AR8600 has been enhanced in several areas. The upper frequency
range has been extended to 3.0GHz (3000MHz), 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. However daily operation of the AR8600 Mark2 is largely
unaffected, just a few operational changes need be noted.
• An LCD / keypad illumination (lamp) dimmer has been added
• The LCD / keypad illumination can be squelch activated
• The rear panel ACC configuration has been amended with audio out now being squelch controlled
• The calibration of SCAN / SEARCH LEVEL has been changed

LAMP DIMMER
There are now effectively three states of LAMP, lamp off / lamp on / dimmer on. While
the lamp is bright for daily operation, in areas of permanent low lighting, it is nice to dim
the lamp. An additional line has been added to the CONFIG MENU, ‘DIMMER’ with a
value of OFF or ON, the default is OFF. To access the CONFIG menu
. The first item in the config menu is “BEEP”. òto move the
cursor to the line marked “DIMMER”. Use the main dial or ï ð keys to toggle the
DIMMER ON / OFF. The key may be used as a short cut to OFF.
to accept the data and return to a standard display. Alternatively to abort entry or ò to
move to the next item on the config menu. Refer to pages 106 - 107 of the operating manual.
SQUELCH OPERATED LAMP
When the lamp is set to AUTO, the lamp will illuminate when the squelch opens. In AUTO mode, the lamp illuminates either
when the keypad is operated or when a signal opens the squelch, after a few seconds the lamp will switch off. There may be
an audible ‘click’ under some circumstances when the lamp automatically switches on and off.
Refer to pages 106 - 107 of the operating manual.
