[Yaesu] Themal drift in SQL in FT-650

Hi!
My FT-650 has developed a problem with the SQL threshold level. When the radio i just switched on the threshold is on SSB/CW close to maximum around 5 o clock. When the radio has been on for several hours the threshold moves to around 10 o clock.
On FM the threshold is constant at 10 o clock at any time or temperature.
AM I have not checked when cold, but even when warm the threshold is near maximum and not "sharpe"
Any ideas?
