KX1 Display Delay

[K8QI]

I just finished building KX1 s/n 2520 on Friday evening.    Have made about 25 contacts with it, getting good reports on the signal quality and all seems to be working as it should.    I do have a question about a delay of the Display.     When transmitting, I get 1 bar (no ATU installed).   When I stop sending there is about a 1 second delay before the Frequency is displayed.    Is this normal??

Thanks
