AR8600 Bulletin Page

The bulletins contained on this page are not generally intended for self-fit

, they generally

represent 'dealer assistance'. Fitting of the optional filters, optional battery and enabling of I.F.

output is intended for action by workshop technicians. No liability is accepted for damage

caused by inexperienced personnel.

AR8600 MK1 to MK2

The AR8600 Mark2 has been introduced during June 2002. The main RF PCB is completely

revised, it is not possible to update a Mark1 to a Mark2 by simple component change... the

frequency coverage has also been extended with a revised CPU being employed.

AR8600 I.F. output

The AR8600 is provided with a rear BNC socket which provides 10.7MHz I.F. output. The

bandwidth is about 2MHz and our workshop measurements using WFM mode suggest that a

positive gain exists between aerial input and I.F. output of 35dB to 40dB across the frequency

bands.

Out of the carton box, I.F. output is limited to WFM mode only to minimise the effects of

internal spurii, as the WFM oscillator is used to produce the 10.7MHz I.F. output. If you wish to

obtain I.F. output in ALL MODES, please refer to the associated bulletin (Acrobat PDF file) -

While the AR8600 may be used with either the SDU5000 or SDU5500 is passive mode, the

RS232 communication with either spectrum display unit is not supported.

Failure of IC410 - over-voltage (early AR8600 MK1)

We have encountered two AR8600 which have suffered damage due to over-voltage power

being applied to the power socket (20V), one via an unregulated power supply and the other by

vehicle connection. Here in the UK we only supply 12V & 15V ‘REGULATED’ power

supplies for the AR8600 (UK manufactured)... we cannot comment on power supplies provided

outside of the UK.
