K3 Power Rise in WSJT-X Modes

[Elecraft mailing list]

I recently noticed when operating in any of WSJT-X modes, such as FT8, the power output on the K3starts out lower than what is initially set then rises to the set power level over the first five to eight seconds of transmitting.The power change is not indicated on radios meter, only my external meter(s).I have checked to see if the same thing occurs in other modes (RTTY, CW, SSB, etc) and it does not. I don't believe it is a K3 issue but I wanted to check and see if perhaps someone else has had a similar experience.Thanks, Bill - W0BBI

Hi Bill,


The problem you're having is typically caused by improper use of the
PWR and MIC controls to set the desired output power. If you try to
use the MIC control to set the output power level, the K3 will attempt
to reach the power level set by the PWR control causing the exact
symptom you're reporting.


First set the PWR control to the desired output power.


Then set the MIC control so that the fifth ALC bar is flickering.


If you need to change to output power; use the PWR control, never
the MIC control.


Good luck!

 Thank you Frank, W3LPL, as you placed me on the right path. It turns out the mic setting was fine, it was my settings on the Navigator interface that I must messed up. All is now well.Thanks again,Bill - W0BBI
