Introduction of new surface mount PCBs
in 9323/9360/9390/9680/9780
Transceivers
Introduction
This Service Bulletin affects users of the 9323/9360/9390/
9680/9780 Transceivers. The thru--hole printed circuit boards
(PCBs) of the Receiver Exciter and the Power Amplifier
assemblies have been replaced with surface mount PCBs (see
Table 1). The new PCBs increase the reliability of the
transceiver, and meet the changing availability of some
components.

Details
The 9323/9360/9390/9680/9780 Transceivers that have been fitted with the new PCBs
have a serial number prefix of J or greater. The serial number prefixes of the transceivers
fitted with the old and new PCBs are listed in Table 2.
During the transition period from thru--hole to surface mount PCBs, some
transceivers may have been manufactured using both thru--hole and surface mount
PCBs.

Software compatibility
Receiver Exciter PCB
Transceivers using software versions earlier than version 4.20
To fit the new Receiver Exciter PCB in transceivers using software versions earlier than
version 4.20, complete the following:
-Upgrade the software to at least version 4.20 (for details see Information Bulletin
IB--00001 and the Service Bulletin 9323/9360/9390 Series—Receiver Exciter (Codan
part number 17--00167)).
-Modify the PCB of the control panel, according to the Application Note 9323 software
upgrade (Codan part number 17--60056).
-Fit the new Receiver Exciter PCB.
Transceivers using software versions 4.20 or later
The new Receiver Exciter PCB can be used as a direct replacement in all transceivers using
software versions 4.20 or later.
Power Amplifier Assembly PCBs
The new Power Amplifier Assembly PCBs can be used as a direct replacement in all
transceivers.
Repair issues
The surface mount PCBs cannot be repaired in the field and should be considered for
module level repairs only.
