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.

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.

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. 17--00208 Issue 1, December 2000 Page 3 of 3
