[Elecraft] K3s - Low Output Power

[Ed Lambert]

My K3s has been in service for several years. Power output has always easily
reached roughly 100 watts.

 

Now, with:

1.	ATU TUNE bypassed
2.	Good 50 ohm dummy load
3.	W1 in line with the load
4.	SWR 1:1

 

Next:

1.	With the PWR control set to show 100 watts on the LCD
2.	Select TUNE
3.	W1 shows about 80 watts output
4.	K3s LCD PWR display shows roughly 80 watts (both the "analog"
display and the numerical display) (depending on band)

 

I just used the K3 Utility to insure my firmware is up to date. It is. And,
I used the Utility to calibrate the transmitter gain. This did NOT change
the results of my power measurements.

 

I am hoping I am making a bone-headed mistake.
