This change is applicable to units prior to serial number 606xxxx.
On the RF unit (X44-1660-00) change C168 from a 33 pF capacitor to a 15 pF 50V capacitor.The following change will increase the VCO level and should prevent reoccurrence of this symptom. Reports of a PLL unlock on the lower frequencies may be due to low VCO levels.
