[Elecraft] K3 Subreceiver problem

[4CX250B]

Hi All,
I installed my KRX3 last week and it seemed to be working well. However, today, during the 10m contest, I suddenly was unable to get any signals through it (just normal audio hiss). Now when I press the SUB button, I see a brief "ERR PL2" message. I tried redoing the VCO calibration for the subreceiver, but at the end of the calibration routine it stopped and the display indicated "E  00008" and "ERR VCO"   Unless I'm doing something stupid - always a possibility - I'm guessing the synthesizer in the subreceiver failed, but thought I'd see if anyone has any suggestions before I contact Customer Support.

FYI, this is my second K3 problem this month. The first was when an output xfmr on the KPA3 module shorted, during the CQ WWDX Test. Somebody up there doesn't want me to work contests with my K3!
