[Yaesu] FT-990 Drifting problem ?

[RHAREL@f8maf1.jer.intel.com (Richard Harel - Tel:6086 Pager: 3/1587)]

I have a Yaesue FT-990 that is drifting on tx and rx - usually a few
10's of hertz but as much as +/- 200 hz. 
Can anyone suggest a fix for this problem ?
Also want to add that the display is not drifting, only the actual rx and tx
freq.
Any info would be appreciated.
Thanks,
Rich
