> 10.6Vdc or
voltage drifting?
Check power on
prescaler buffer output,
C823 using field probe.
Is power at
C823 >-15dBm?
Check if VCO is lock at
desired frequency using
field probe.
VCO locked?
Check parts around
U702. If OK, replace
U702.
Check lock_det line
circuitry in controller
section. Check R281
1 and
R2812 for continuity
.
Check loop filter R701,
R705, R708, C703,
C707, C713 for
continuity
. Fault found?
Replace suspected
