[Elecraft] K3 TX moving away from RX frequency

[Yuri VE3XB]

Hello,

 

Recently I noticed that my transmit frequency is getting further away from
the receive and I have to use RIT in order to hear stations coming to my CQ.

Before, the difference was very small, just few Hz, but now I tune RIT up to
.25 - .30 kHz and it's not getting any better.

I went through couple years of messages but didn't find any mention of this
problem.

Is there known fix for that?

 

Thanks in advance,
