[Elecraft] KX3 oscillator temperature

I recently started extensive temperature testing on the KX3 to get more data
on dissipation and stability.
For starters stability in RX. KX3 in original setup. Serial below #2000
I noticed that for a steady ambient temperature the oscillator temperature
varies with frequency used.
Has anyone else similar observations? Temp taken after long (2h) warm up
For example: 
50MHz: 39°C 
28MHz: 37°C
 7MHz: 36°C

PA in RX remains 28°C
Any feedback is welcome.
