[Elecraft] K3 Power ON audio trouble

[IK2HKT - Sten]

Hi guys, 
I have trouble with my K3 when push power switch ON. 
If the RTX is switch OFF in SSB, AM or DATA mode and after is power 
ON, everythink is ok. 
But if I power OFF the RTX in CW mode, when I push the power ON, the audio 
on speaker or headphone is at maximum level for half second, just the 
time to see all data on the diplay. After the audio go less 
accordly to the position of AF potentiomenter and everythink work perfect. 
Seem to be a problem of "chek up" in the little time when the power 
switch is push ON (and no information appear on the display). 
As soon as the diplay have information, the audio work perfectly. 
I download the latest firmware, I tried several time with different
configuration 
(such as filters, only headphone, only speakers and others) but the problem
persist. 
Everytime switch off/on on SSB all is OK  --- Only when in CW mode the 
audio go to the max level just and half of second after the power on switch
is 
pressed. 
Any suggestion about this matter ? .... Some of you have note the 
same trouble? 
Thanks in advance for help!
