Hi Don, I have checked it with both my Bird 43 and Daiwa CN801. Both with the same results. Now with the K3 warmed up there is no problem. I will have to wait for another cold start since I didn't even bother to see if the power meter in the K3 was tracking with the other two. I'll post again when on a cold start if the K3 tracks the same.

There is a big difference in how your situation can be analyzed depending on whether the power increase is noted by the K3 display or whether with an external wattmeter. I am not saying that you have no problem, but that the area to look can be different depending on how you observe the power increase. 73, Don W3FPR On 11/30/2019 1:26 PM, Jim Kennedy wrote: > Fired up my K3 the last couple of mornings and noticed this.
